Done.
Instead of converting data to String try to convert it Dictionary direct
let task = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
let response = try NSJSONSerialization.JSONObjectWithData(data!, options:.MutableContainers) as! [String: AnyObject]
let status = response["status"] as! String
if status == "success" {
let array = response["result"] as! [[String: AnyObject]]
print(array)
}
})
Note: You have already written your code inside do block thats why i have not declare that block for try, you just need to replace your task block with my one.
Edit:
func callAddWithPOST(Name mname:String, PhoneNo mphone:String, Email memail:String, Comment mcomments:String){
let login = ["countryId":"1"]
print("Your Result is : = \(login)")
let url = NSURL(string: "http://photokeeper.mgtcloud.co.uk/commonwebservice.asmx/getStateList")!
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: url)
do {
let auth = try NSJSONSerialization.dataWithJSONObject(login, options: .PrettyPrinted)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.HTTPMethod = "POST"
request.HTTPBody = auth
let task = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
let response = try NSJSONSerialization.JSONObjectWithData(data!, options:.MutableContainers) as! [String: AnyObject]
let status = response["status"] as! String
if status == "success" {
let array = response["result"] as! [[String: AnyObject]]
print(array)
}
})
task.resume()
} catch let error as NSError {
print(error.localizedDescription)
}
}

URL Session Post with form-data parameter in iOS Swift
I am trying to POST a parameter using form-data in swift.
I want to pass a mobile number with url session in form-data format. but I can't able to send data properly . please help me to pass data on form-data format in url session.
code I have Tried:
func registerService(){
print("register tapped")
let parameters: [String: Any] = [
"mobile" : mobileNumber
]
let url = URL(string: "http://54.251.198.30/api/user/login")
var req = URLRequest(url: url!)
req.httpMethod = "POST"
let boundary = "Boundary-\(UUID().uuidString)"
req.addValue("multipart/form-data : \(boundary)", forHTTPHeaderField: "Contet-Type")
req.addValue("multipart/form-data", forHTTPHeaderField: "Accept")
req.httpBody = NSKeyedArchiver.archivedData(withRootObject: parameters)
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) else {return}
req.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: req, completionHandler: {(data, response, error) in
if response != nil {
print(response)
}

print(jsonResponse)
}else{
print("error")
}
}).resume()
}
I have added an image which parameter I want to pass. you Can see Here
thanks for your response
I have modified your function parameter as well as request-body in the correct syntax. Now you can use as follows:-
func Register(){
print("register tapped")
let parameters: [String: Any] = ["mobile" : mobileNumber] as Dictionary<String, Any>
var request = URLRequest(url: URL(string: "http://54.251.198.30/api/user/login")!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: [])
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
let task = session.dataTask(with: request, completionHandler: { data, response, error -> Void in
print(response!)
do {
let json = try JSONSerialization.jsonObject(with: data!) as! Dictionary<String, AnyObject>
print(json)
} catch {
print("error")
}
})
task.resume()
}
Swift: How to add Dictionary format in forHTTPHeaderField in GET request
In GET request, I am trying to add header.
request.setValue(value: String?, forHTTPHeaderField: "SessionInfo")
But, SessionInfo value is in [String : Any]
Attempt 1:
func SO_Function() {
let service_url = WebService.sharedManager().serviceURL
let getMenuURL = service_url + "/MyPage/FileDownload.ashx"
var convertedString = ""
do {
let data1 = try JSONSerialization.data(withJSONObject: WebService.sharedManager().mobInfoDict, options: [])
convertedString = String(data: data1, encoding: .utf8)!
print("\n\nconvertedJSONtoData ", convertedString)
} catch {
print("\n\nCAtcLL___Err ",error.localizedDescription)
}
let url = NSURL(string: getMenuURL)
let request = NSMutableURLRequest(url: url! as URL)
//Below line, If I can able to add [String:Any] then I will get
proper Image as output.
request.setValue(convertedString, forHTTPHeaderField: "SessionInfo")
request.setValue("67a2a6fb1d13450a", forHTTPHeaderField: "Flowid")
request.setValue("d29566ac42de4e99", forHTTPHeaderField: "Fileid")
request.setValue("LMS_LEAVEREQUEST", forHTTPHeaderField: "Form")
request.httpMethod = "GET"
let session = URLSession.shared
let mData = session.dataTask(with: request as URLRequest) { (data, response, error) -> Void in
if let res = response as? HTTPURLResponse {
DispatchQueue.main.async {
let img = UIImage(data: data!)
self.attachmentImgVw.image = img
}
}else{
print("\n\nError: \(String(describing: error))")
}
}
mData.resume()
}
Output
The data couldn’t be read because it isn’t in the correct format.

In postman, I am giving SessionInfo value as in Dictionary format. Working fine.
How to solve this issue?
urlrequest not sending post request
Hi i am new to IOS App developement.
My code is
func sendRequest<T: Decodable>(api: String, parameters: [String: String]? = nil, outputBlock: #escaping (T) -> () ) {
guard let url = URL(string: "http://xxyyzz.com/appRegister.php") else {return}
print("hitting : -", url.absoluteString)
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let newparam = ["name": "rr", "pass": "123456", "email": "rr#rr.com", "passConfirm":"123456"]
let httpBody = try? JSONSerialization.data(withJSONObject: newparam)
request.httpBody = httpBody
if let data = request.httpBody, let str = String(data: data, encoding: String.Encoding.utf8) {
print(str)
}
URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
DispatchQueue.main.async {
Indicator.shared.hideProgressView()
if let err = error {
print(err.localizedDescription)
return
}
guard let data = data else {return}
do {
let obj = String(data: data, encoding: String.Encoding.utf8)
print(obj ?? "oberrrrr")
}
}
}.resume()
}
and console printed result as per code is below
hitting : - http://xxyyzz.com/appRegister.php
{"email":"rr#rr.com","passConfirm":"123456","name":"rr","pass":"123456"}
{"error":"Please enter all fields."}
url and parameters works well on postman that means their is something missing in my code.
just to answer the problem if anyone else faces this.
this code is fine but the problem was with php web-service as the backend developer was not accepting json values as parameter instead form data was need to send.
So, two types of fix can be made here
accept json at backend by adding :-
$postdata = file_get_contents("php://input");
$request = json_decode($postdata, true);
send form data instead json
func sendRequest<T: Decodable>(api: String, parameters: [String: Any]? = nil, outputBlock: #escaping (T) -> () ) {
guard let url = URL(string: api) else {return}
print("hitting : -", url.absoluteString)
var request = URLRequest(url: url)
if let parameters = parameters {
request.httpMethod = "POST"
var postArr = [String]()
for(key, value) in parameters
{
postArr.append(key + "=\(value)")
}
let postString = postArr.map { String($0) }.joined(separator: "&")
request.httpBody = postString.data(using: .utf8)
if let data = request.httpBody, let str = String(data: data, encoding: String.Encoding.utf8) {
print(str)
}
}
URLSession.shared.dataTask(with: request) { (data, response, error) in
DispatchQueue.main.async {
Indicator.shared.hideProgressView()
if let err = error {
print(err.localizedDescription)
return
}
guard let data = data else {return}
do {
let obj = try JSONDecoder().decode(T.self, from: data)
outputBlock(obj)
} catch let jsonErr {
print(jsonErr)
}
}
}.resume()
}
Send dictionary data via HTTP POST method in Swift
I'm trying to make an HTTP post request with params set in a dictionary here's my dict
let parameters = [
["name": "tag","value": "login"],
["name": "email","value": "s#s.com"],
["name": "password","value": "aaaa"]
]
but I don't to know how to access it in hers's my complete request function
func data_request(_ url:String)
{
let parameter = [
["name": "tag","value": "login"],
["name": "email","value": "s#s.com"],
["name": "password","value": "aaaa"]
]
let url:NSURL = NSURL(string: url)!
let session = URLSession.shared
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
let paramString = parameter?
request.httpBody = paramString.data(using: String.Encoding.utf8)
let task = session.dataTask(with: request as URLRequest) {
(
data, response, error) in
guard let _:NSData = data as NSData?, let _:URLResponse = response, error == nil else {
print("error")
return
}
if let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
{
print(dataString)
}
}
task.resume()
}
Need to convert dictionary to json string like below:
let jsonData = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
After that pass to the http.Body
// insert json data to the request
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = jsonData
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
if error != nil{
print("Error -> \(error)")
return
}
do {
let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject]
print("Result -> \(result)")
} catch {
print("Error -> \(error)")
}
}
task.resume()
return task
} catch {
print(error)
}
You need to convert the Dictionary into Data and set it to httpBody you could solve in this way let paramData = try? JSONSerialization.data(withJSONObject: parameter, options: []) request.httpBody = paramData
Why does post request work much faster from the second call?
I launch the app. Press the button which call this function, wait 2-3 seconds and than get the JSON. Then I press it again, wait 0-1 and then I get the JSON. Can you explain me the reason why it's happening and how can I avoid it?
public func serverUserRegister(userPhone: String?, userEmail: String?, completionHandler: #escaping ((String) -> ())) {
if let phone = userPhone {
if let email = userEmail {
let url = URL(string: "https://example.com/service.php")!
let session = URLSession.shared
let request = NSMutableURLRequest(url: url)
request.httpMethod = "POST"
request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
let paramString = "phone=\(phone)&email=\(email)"
request.httpBody = paramString.data(using: .utf8)
let task = session.dataTask(with: request as URLRequest) { (data, response, error) in
guard let _: Data = data, let _: URLResponse = response, error == nil else {
return
}
if let json = try? JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary {
if let jsonStatus = json?["status"] as? String {
completionHandler(jsonStatus)
}
}
}
task.resume()
}
}
}
