I am facing an issue with Alamofire requests and interceptor.
I have two types of responses from my server -> Success response which is kind of object and the error response which is always a message what's wrong.
I founded a sample code to create a very own function for decoding two types of responses which seems to work well.
The problem occurs after the Alamofire adapt function is called (adapt add a cookies for each request) -> in my .responseTwoDecodable i'll get always response as nil but the status code is 200 and everything is fine, server returns object but alamofire is ignoring it.
Here is my code for each request:
func request<T: Decodable>(
_ url: String,
method: HTTPMethod = .get,
parameters: Parameters? = nil,
decoder: JSONDecoder = JSONDecoder(),
headers: HTTPHeaders? = nil,
interceptor: RequestInterceptor? = nil
) -> Future<T, ServerError> {
return Future({ promise in
AF.request(
url,
method: method,
parameters: parameters,
encoding: JSONEncoding.default,
headers: headers
interceptor: interceptor ?? self
)
.validate(statusCode: [200, 201, 204, 401]
.responseTwoDecodable(of: T.self) { response in
switch response {
case .success(let value):
promise(.success(value))
case .failure(let error):
promise(.failure(error))
}
}
})
}
Here is adapt function:
func adapt(_ urlRequest: URLRequest, for session: Session, completion: #escaping (Result<URLRequest, ServerError>) -> Void) {
let request = urlRequest
if let accessToken = UserDefaults.standard.string(forKey: Constants.accessToken), let refreshToken = UserDefaults.standard.string(forKey: Constants.refreshToken) {
let access = [
HTTPCookiePropertyKey.domain: Constants.cookieDomain,
HTTPCookiePropertyKey.path: Constants.cookieAccessPath,
HTTPCookiePropertyKey.name: Constants.accessToken,
HTTPCookiePropertyKey.value: accessToken
]
let refresh = [
HTTPCookiePropertyKey.domain: Constants.cookieDomain,
HTTPCookiePropertyKey.path: Constants.cookieRefreshPath,
HTTPCookiePropertyKey.name: Constants.refreshToken,
HTTPCookiePropertyKey.value: refreshToken
]
if let accessCookie = HTTPCookie(properties: access), let refreshCookie = HTTPCookie(properties: refresh) {
AF.session.configuration.httpCookieStorage?.setCookie(accessCookie)
AF.session.configuration.httpCookieStorage?.setCookie(refreshCookie)
completion(.success(request))
}
}
completion(.success(request))
}
And here is my decoding code for two decodables:
struct ErrorMessage: Error, Decodable {
let message: String
}
struct ServerError: Error {
var message: String
var code: ServerErrorCodes
let args: [String]?
}
enum ServerErrorCodes: Int {
case unauthorized = 401
case forbidden = 403
case internalServerError = 500
case notFound = 404
case conflict = 409
case unknown
case emptyResponse
case unserialized
case userInput
case coreData
}
final class TwoDecodableResponseSerializer<T: Decodable>: ResponseSerializer {
lazy var decoder: JSONDecoder = {
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .iso8601
return decoder
}()
private lazy var successSerializer = DecodableResponseSerializer<T>(decoder: decoder)
private lazy var errorSerializer = DecodableResponseSerializer<ErrorMessage>(decoder: decoder)
public func serialize(request: URLRequest?, response: HTTPURLResponse?, data: Data?, error: Error?) throws -> Result<T, ServerError> {
guard error == nil else { return .failure(ServerError(message: "Unknown error", code: .unknown, args: [])) }
guard let response = response else { return .failure(ServerError(message: "Empty response", code: .emptyResponse, args: [])) } // HERE I AM GETTING A NIL AS A RESPONSE, BUT SERVER RESPONDED WITH CORRECT BODY AND 200 AS STATUS CODE
do {
print(response.debugDescription)
if response.statusCode < 200 || response.statusCode >= 300 {
let serverMessage = try errorSerializer.serialize(request: request, response: response, data: data, error: nil)
let responseCode: ServerErrorCodes
if let code = ServerErrorCodes(rawValue: response.statusCode) {
responseCode = code
} else {
responseCode = .unknown
}
let result = ServerError(message: serverMessage.message, code: responseCode, args: nil)
return .failure(result)
} else {
let result = try successSerializer.serialize(request: request, response: response, data: data, error: nil)
return .success(result)
}
} catch(let err) {
return .failure(ServerError(message: "Could not serialize body", code: .unserialized, args: [String(data: data!, encoding: .utf8)!, err.localizedDescription]))
}
}
}
extension DataRequest {
#discardableResult func responseTwoDecodable<T: Decodable>(queue: DispatchQueue = DispatchQueue.global(qos: .userInitiated), of t: T.Type, completionHandler: #escaping (Result<T, ServerError>) -> Void) -> Self {
return response(queue: .main, responseSerializer: TwoDecodableResponseSerializer<T>()) { response in
switch response.result {
case .success(let result):
completionHandler(result)
case .failure(let error):
completionHandler(.failure(ServerError(message: "Other error", code: .unknown, args: [error.localizedDescription])))
}
}
}
}
I am a newbie in Alamofire, so if something can be done in better way, I will appreciate your help or sharing your thoughts! Has anybody idea why this can happen? Thanks!
SOLVED: I completely wipe out the code implementing .responseTwoDecodable and write very own solution:
func createError(response: HTTPURLResponse?, error: AFError, data: Data?) -> ServerError {
guard let serverResponse = response else {
return .init(message: "Unknown error", code: .unknown, args: [error.localizedDescription])
}
guard let serverData = data else {
return .init(message: "Empty response", code: .emptyResponse, args: [error.localizedDescription])
}
let responseCode: ServerErrorCodes
if let code = ServerErrorCodes(rawValue: serverResponse.statusCode) {
responseCode = code
} else {
responseCode = .unknown
}
do {
let serverMessage = try JSONDecoder().decode(ErrorMessage.self, from: serverData)
return .init(message: serverMessage.message, code: responseCode, args: [])
} catch (let error) {
return .init(message: "Body not serializable", code: .unserialized, args: [String(data: serverData, encoding: .utf8) ?? "", error.localizedDescription])
}
}
And calling it like:
.responseDecodable(completionHandler: { (response: DataResponse<T, AFError>) in
switch response.result {
case .success(let value):
promise(.success(value))
case .failure(let error):
promise(.failure(self.createError(response: response.response, error: error, data: response.data)))
}
})
With this code I was able to decode all the errors from the server as expected.
Following code I have written and I am getting response in JSON also but the type of JSON is "AnyObject" and I am not able to convert that into Array so that I can use that.
Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
(request, response, JSON, error) in
println(JSON?)
}
The answer for Swift 2.0 Alamofire 3.0 should actually look more like this:
Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
case .Success(let JSON):
print("Success with JSON: \(JSON)")
let response = JSON as! NSDictionary
//example if there is an id
let userId = response.objectForKey("id")!
case .Failure(let error):
print("Request failed with error: \(error)")
}
}
https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%203.0%20Migration%20Guide.md
UPDATE for Alamofire 4.0 and Swift 3.0 :
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
//to get status code
if let status = response.response?.statusCode {
switch(status){
case 201:
print("example success")
default:
print("error with response status: \(status)")
}
}
//to get JSON return value
if let result = response.result.value {
let JSON = result as! NSDictionary
print(JSON)
}
}
like above mention you can use SwiftyJSON library and get your values like i have done below
Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
(request, response, data, error) in
var json = JSON(data: data!)
println(json)
println(json["productList"][1])
}
my json product list return from script
{ "productList" :[
{"productName" : "PIZZA","id" : "1","productRate" : "120.00","productDescription" : "PIZZA AT 120Rs","productImage" : "uploads\/pizza.jpeg"},
{"productName" : "BURGER","id" : "2","productRate" : "100.00","productDescription" : "BURGER AT Rs 100","productImage" : "uploads/Burgers.jpg"}
]
}
output :
{
"productName" : "BURGER",
"id" : "2",
"productRate" : "100.00",
"productDescription" : "BURGER AT Rs 100",
"productImage" : "uploads/Burgers.jpg"
}
Swift 3, Alamofire 4.4, and SwiftyJSON:
Alamofire.request(url, method: .get)
.responseJSON { response in
if response.data != nil {
let json = JSON(data: response.data!)
let name = json["people"][0]["name"].string
if name != nil {
print(name!)
}
}
}
That will parse this JSON input:
{
people: [
{ name: 'John' },
{ name: 'Dave' }
]
}
I found the answer on GitHub for Swift2
https://github.com/Alamofire/Alamofire/issues/641
Alamofire.request(.GET, URLString, parameters: ["foo": "bar"])
.responseJSON { request, response, result in
switch result {
case .Success(let JSON):
print("Success with JSON: \(JSON)")
case .Failure(let data, let error):
print("Request failed with error: \(error)")
if let data = data {
print("Response data: \(NSString(data: data, encoding: NSUTF8StringEncoding)!)")
}
}
}
I'm neither a JSON expert nor a Swift expert, but the following is working for me. :) I have extracted the code from my current app, and only changed "MyLog to println", and indented with spaces to get it to show as a code block (hopefully I didn't break it).
func getServerCourseVersion(){
Alamofire.request(.GET,"\(PUBLIC_URL)/vtcver.php")
.responseJSON { (_,_, JSON, _) in
if let jsonResult = JSON as? Array<Dictionary<String,String>> {
let courseName = jsonResult[0]["courseName"]
let courseVersion = jsonResult[0]["courseVersion"]
let courseZipFile = jsonResult[0]["courseZipFile"]
println("JSON: courseName: \(courseName)")
println("JSON: courseVersion: \(courseVersion)")
println("JSON: courseZipFile: \(courseZipFile)")
}
}
}
Hope this helps.
Edit:
For reference, here is what my PHP Script returns:
[{"courseName": "Training Title","courseVersion": "1.01","courseZipFile": "101/files.zip"}]
Swift 5
class User: Decodable {
var name: String
var email: String
var token: String
enum CodingKeys: String, CodingKey {
case name
case email
case token
}
public required init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
self.name = try container.decode(String.self, forKey: .name)
self.email = try container.decode(String.self, forKey: .email)
self.token = try container.decode(String.self, forKey: .token)
}
}
Alamofire API
Alamofire.request("url.endpoint/path", method: .get, parameters: params, encoding: URLEncoding.queryString, headers: nil)
.validate()
.responseJSON { response in
switch (response.result) {
case .success( _):
do {
let users = try JSONDecoder().decode([User].self, from: response.data!)
print(users)
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}
case .failure(let error):
print("Request error: \(error.localizedDescription)")
}
swift 3
pod 'Alamofire', '~> 4.4'
pod 'SwiftyJSON'
File json format:
{
"codeAd": {
"dateExpire": "2017/12/11",
"codeRemoveAd":"1231243134"
}
}
import Alamofire
import SwiftyJSON
private func downloadJson() {
Alamofire.request("https://yourlinkdownloadjson/abc").responseJSON { response in
debugPrint(response)
if let json = response.data {
let data = JSON(data: json)
print("data\(data["codeAd"]["dateExpire"])")
print("data\(data["codeAd"]["codeRemoveAd"])")
}
}
}
This was build with Xcode 10.1 and Swift 4
Perfect combination "Alamofire"(4.8.1) and "SwiftyJSON"(4.2.0). First you should install both pods
pod 'Alamofire' and pod 'SwiftyJSON'
The server response in JSON format:
{
"args": {},
"headers": {
"Accept": "*/*",
"Accept-Encoding": "gzip;q=1.0, compress;q=0.5",
"Accept-Language": "en;q=1.0",
"Host": "httpbin.org",
"User-Agent": "AlamoFire TEST/1.0 (com.ighost.AlamoFire-TEST; build:1; iOS 12.1.0) Alamofire/4.8.1"
},
"origin": "200.55.140.181, 200.55.140.181",
"url": "https://httpbin.org/get"
}
In this case I want print the "Host" info : "Host": "httpbin.org"
Alamofire.request("https://httpbin.org/get").validate().responseJSON { response in
switch response.result {
case .success:
print("Validation Successful)")
if let json = response.data {
do{
let data = try JSON(data: json)
let str = data["headers"]["Host"]
print("DATA PARSED: \(str)")
}
catch{
print("JSON Error")
}
}
case .failure(let error):
print(error)
}
}
Keep Calm and happy Code😎
I found a way to convert the response.result.value (inside an Alamofire responseJSON closure) into JSON format that I use in my app.
I'm using Alamofire 3 and Swift 2.2.
Here's the code I used:
Alamofire.request(.POST, requestString,
parameters: parameters,
encoding: .JSON,
headers: headers).validate(statusCode: 200..<303)
.validate(contentType: ["application/json"])
.responseJSON { (response) in
NSLog("response = \(response)")
switch response.result {
case .Success:
guard let resultValue = response.result.value else {
NSLog("Result value in response is nil")
completionHandler(response: nil)
return
}
let responseJSON = JSON(resultValue)
// I do any processing this function needs to do with the JSON here
// Here I call a completionHandler I wrote for the success case
break
case .Failure(let error):
NSLog("Error result: \(error)")
// Here I call a completionHandler I wrote for the failure case
return
}
I usually use Gloss library to serialize or deserialize JSON in iOS. For example, I have JSON that looks like this:
{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}
First, I model the JSON array in Gloss struct:
Struct Struct_Name: Decodable {
let IJ: String?
let KL: String?
init?(json: JSON){
self.IJ = "AB" <~~ json
self.KL = "CD" <~~ json
}
}
And then in Alamofire responseJSON, I do this following thing:
Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
switch response.result{
case .success (let data):
guard let value = data as? JSON,
let eventsArrayJSON = value["ABDC"] as? [JSON]
else { fatalError() }
let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
for i in 0 ..< Int((struct_name?.count)!) {
print((struct_name?[i].IJ!)!)
print((struct_name?[i].KL!)!)
}
break
case .failure(let error):
print("Error: \(error)")
break
}
}
The output from the code above:
qwerty
uiop
1234
asdf
in swift 5 we do like, Use typealias for the completion. Typlealias nothing just use to clean the code.
typealias response = (Bool,Any?)->()
static func postCall(_ url : String, param : [String : Any],completion : #escaping response){
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: [:]).responseJSON { (response) in
switch response.result {
case .success(let JSON):
print("\n\n Success value and JSON: \(JSON)")
case .failure(let error):
print("\n\n Request failed with error: \(error)")
}
}
}
The easy answer is to let AlamoFire do the decoding directly.
Surprisingly, you don't use the .responseJSON because that returns an untyped json object
Instead, you make your objects Decodable - and ask AF to decode directly to them
My json response contains an array of Account objects. I only care about the id and name keys (though there are many more)
struct Account:Codable {
let id:Int
let name:String
}
then simply
AF.request(url,
method: .get)
.responseDecodable(of:[Account].self) { response in
switch response.result {
case .success:
switch response.response?.statusCode {
case 200:
//response.value is of type [Account]
default:
//handle other cases
}
case let .failure(error):
//probably the decoding failed because your json doesn't match the expected format
}

Anyone can show us some tips or say what might be wrong?
Thanks to all the community!
-> I have created a dynamic function for uploading Image and Files you can even upload multiple images and files my this
func makeFormDataAPICall<T: Codable>(url: String, params: [String: Any], objectType: T.Type,
success: #escaping(_ responseObject: T) -> Void,
failure: #escaping (_ error: String) -> Void) {
let name = self.randomNumberWith(digits: 6)
self.headers = [kAuthorization: self.userData?.authToken ?? ""]
//Network check
if Utilities.isConnectedToNetwork() {
guard let urlIs = URL(string: url) else {
failure(ServerAPI.errorMessages.kServerDownError)
return
}
// Almofire upload request
AF.upload(multipartFormData: { multiPartData in
for (key, value) in params {
if value is UIImage {
let img = (value as? UIImage)?.jpegData(compressionQuality: 0.5)
multiPartData.append(img!, withName: key, fileName: "img_\(name).jpeg", mimeType: "image/jpeg")
} else if value is NSArray {
for childValue in value as? NSArray ?? [] {
if childValue is UIImage {
let img = (childValue as? UIImage)?.jpegData(compressionQuality: 0.5)
multiPartData.append(img!, withName: key, fileName: "profile_image.png", mimeType: "image/jpeg")
}
}
} else if value is NSURL || value is URL {
do {
guard let pdf: URL = value as? URL else { return }
let name = pdf.lastPathComponent
let mimeType = pdf.mimeType()
let pdfData = try Data(contentsOf: pdf)
multiPartData.append(pdfData, withName: key, fileName: name, mimeType: mimeType)
} catch { print(error) }
} else {
if value is String || value is Int || value is Bool {
multiPartData.append("\(value)".data(using: .utf8)!, withName: key)
}
}
}
}, to: urlIs,method: .post, headers: headers).responseDecodable(of: FetchAPI<T>.self) { response in
// preetify data
if let data = response.data {
let str = data.prettyPrintedJSONString!
Logger.logResponse(ofAPI: "\(urlIs)", logType: .success, object: str)
}
// response result
switch response.result {
case .success(let data):
// check auth token Exp condition
if data.statusCode == 401 {
let appDelegate = AppDelegate.shared()
let rootVC = R.storyboard.auth.authNavigationController()!
appDelegate.window?.rootViewController = rootVC
return
}
// check flag status
if data.flag! { success(data.data!) } else { failure(data.message!) }
case .failure(let error):
failure("Something went wrong.")
Logger.log(logType: .error, object: error.localizedDescription)
}
}
} else { failure(ServerAPI.errorMessages.kNoInternetConnectionMessage) }
}
-> Usage
APIManager.shared.makeFormDataAPICall(url: ServerAPI.editProfile, params: params, objectType: User.self, success: { response in
success(response)
print(response)
}, failure: { error in
failure(error)
}) // 1st Parameter is URL 2nd Parameter are params to send
//3rd parameter is Object to which you want to convert the Json data into
//4th and 5th parameter are compilation handler which gives you response and errors accordingly
-> you can remove auth token conditions which I have written for myself
-> if you are passing data in json you just have to write JSONEncoding: JSONEncoding.default before "header parameter" in almofire function
I tried convert the below code on Swift 3:
session.dataTaskWithURL(url! as URL, completionHandler: { (data : NSData?, response : URLResponse?, error : NSError?) -> Void in
if error != nil {
callback(items: nil, errorDescription: error!.localizedDescription, placesDetail: [])
}
if let statusCode = response as? NSHTTPURLResponse {
if statusCode.statusCode != 200 {
callback(items: nil, errorDescription: "Could not continue. HTTP Status Code was \(statusCode)", placesDetail: [])
}
}
NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
callback(items: GooglePlaces.parseFromData(data!), errorDescription: nil, placesDetail: GooglePlaces.arrayPlaces(data!))
})
}).resume()
So I do it:
session.dataTask(with: url!) { (data, response, error) -> Void in
if error != nil {
callback(items: nil, errorDescription: error!.localizedDescription, placesDetail: [])
}
if let statusCode = response as? NSHTTPURLResponse {
if statusCode.statusCode != 200 {
callback(items: nil, errorDescription: "Could not continue. HTTP Status Code was \(statusCode)", placesDetail: [])
}
}
OperationQueue.main.addOperation {
callback(items: GooglePlaces.parseFromData(data!), errorDescription: nil, placesDetail: GooglePlaces.arrayPlaces(data!))
}
}
But Have this error:
Ambiguous reference to member 'dataTask(with:completionHandler:)'
Why this error?
You are getting this error because in Swift 3 they have used all the API with URL not NSURL, so simply create the object of URL instead of NSURL and pass as first argument of dataTask(with:completionHandler:).
let url = URL(string: stringURL)
//Now this will works for you
session.dataTask(with: url!) { (data, response, error) -> Void in
For more details on this check URLSession documentations.
Note: You can also use.
dataTask(with request: URLRequest, completionHandler: #escaping (Data?, URLResponse?, Error?) -> Void) -> URLSessionDataTask
But for this you need to create URLRequest object not NSURLRequest.
You need to change only in Swift 3
session.dataTask(with: url!) { (data, response, error) -> Void in
to
session.dataTask(with: url as URLRequest) {
data, response, error in
Try this below code for URLSession in Swift 3
//MARK:- Parsing API here
public static func getparseMyApi(_ input: String, action:String, completion: #escaping (_ result: String, _ error: NSError?) -> Void) {
//Main API here
let is_URL: String = "http://yourURLhere.com"
let lobj_Request = NSMutableURLRequest(url: URL(string: is_URL)!)
let session = URLSession.shared
lobj_Request.httpMethod = "POST"
lobj_Request.httpBody = input.data(using: String.Encoding.utf8)
//lobj_Request.addValue("www.cgsapi.com", forHTTPHeaderField: "Host")
lobj_Request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
lobj_Request.addValue(String(input.characters.count), forHTTPHeaderField: "Content-Length")
lobj_Request.addValue("http://tempuri.org/IService/\(action)", forHTTPHeaderField: "SOAPAction")
let task = session.dataTask(with: lobj_Request as URLRequest) {
data, response, error in
print("Response: \(response)")
// Checking here Response
if response != nil {
let statusCode = (response as! HTTPURLResponse).statusCode
print("Success: \(statusCode)")
// Checking here Response Status
if statusCode == 200 {
//Handling Data here
if data?.count > 0 {
//Do something here with data
let strData = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
// Finish here Process
completion(strData, nil)
}else{
//Data nil Condition here
completion("", error as NSError?)
}
//Handling Error here
if error != nil
{
print("Error: " + error.debugDescription)
completion("", error as NSError?)
}
}else{
//Invalid Status
print("Error: " + error.debugDescription)
completion("", error as NSError?)
}
}else{
//Response Nil then handle here
print("Error: " + error.debugDescription)
completion("", error as NSError?)
}
}
task.resume()
}

How can I get response from POST method using Alamofire?
I have next POST method:
let parameters = [
"Firstname": "\(first_name)",
"Lastname": "\(last_name)",
];
Alamofire.request(.POST, URLString, parameters: parameters as? [String : AnyObject], encoding: .JSON)
And when this is done, I want to get a response my record with ID and other fields. How can I do it?
You can write a method like this...
func getData(result: (response: NSMutableArray!, error : NSError!) -> Void){
let parameters = [
"Firstname": "\(first_name)",
"Lastname": "\(last_name)", ];
//Request to fetch data from the server
Alamofire.request(.POST,URLString, parameters: parameters,encoding:.JSON).responseJSON
{ response in switch response.result {
case .Success(let jsonData):
result(response: jsonData as! NSMutableArray, error: nil)
case .Failure(let error):
result(response: nil, error: error)
}
}
}//getData
And call above method as...
YOURCLASSOBJECT.getFeedData( { (response, error) -> Void in
//If data is fetched successfully
if(response != nil){
print("Response : \(response)")
}
})
Alamofire.request(.POST, URLString, parameters:parameters,encoding:.JSON).responseJSON { (response) -> Void in
if response.result.value != nil {
print(response.result.value)
}
}
