I am trying to send a post request with Alamofire 4.6. I am having an issue where it does not seem like the body of the request is never being reached. The server Is never getting a request and the print statements are never being hit. I am led to believe that the request is never started up.
let jsonData = ["request":
["method": "phoneNumberVerificationStart","id": 1,
"params":
["number": "\(PhoneNumber)"] ]]
let urlString = "*************************************"
let requestURL = URLRequest(url: URL(string: urlString)!)
let finalRequest = Alamofire.request(urlString, method: .post, parameters: jsonData, encoding: JSONEncoding.default, headers: nil)
finalRequest.responseJSON{
request in
print(request)
print("I am IN the request")
}
print("Here after Request")
The "Here after the Request" prints out but the "I am IN the request" never is hit so I am led to believe that the async call is never called. Does anyone have an idea what the issue is?

I have an URL that I, when called in a webbrowser, will redirect me 2 times and in the response header of the second redirect it will send the Information that I want to extract.
So to automatically extract that information in swift, I wrote this short piece of code that makes the HTTP Request and then prints the response headers:
printv(text: "Loading JSID Location")
req = URLRequest.init(url: JSIDLocation!)
var task : URLSessionDataTask
task = URLSession.shared.dataTask(with: req) {(data, response, error) in
if let res = response as? HTTPURLResponse {
res.allHeaderFields.forEach { (arg0) in
let (key, value) = arg0
self.printv(text: "\(key): \(value)")
}
}
self.printv(text: String.init(data: data!, encoding: String.Encoding.utf8)!)
}
task.resume()
(printv is a function that will format the string and print it to a label)
So when I run this, I expect it to print the response headers and the body of the last redirect, but what actually happens is that i just prints response headers and body of the original URL. As those don't contain the information im looking for, that won't help me. I already googled my problem, and I found out that HTTP Redirects by default are activated in URLSessions and that you'd had to mess with URLSessionDelegates in order to deactivate them but that's definetly not something I did.
Thank you for your help!
If you want redirect information, you need to become the URLSessionDataTaskDelegate.
let session = URLSession(configuration: .default, delegate: self, delegateQueue: nil)
Then you need to implement, the redirection delegate function and be sure to call the completion handler with the given new redirect request:
func urlSession(_ session: URLSession, task: URLSessionTask, willPerformHTTPRedirection response: HTTPURLResponse, newRequest request: URLRequest, completionHandler: #escaping (URLRequest?) -> Void) {
// operate on response to learn about the headers here
completionHandler(request)
}
I'm trying to find the correct syntax for calling ecobee's API from Swift 4 using Alamofire.
Their cURL example:
curl -H "Content-Type: text/json" -H "Authorization: Bearer ACCESS_TOKEN" 'https://api.ecobee.com/1/thermostat?format=json&body=\{"selection":\{"selectionType":"registered","selectionMatch":"","includeRuntime":true\}\}'
The closest I've been to a solution is this
func doRequest() {
guard let url = URL(string: "https://api.ecobee.com/1/thermostat?format=json") else { return }
let parameters: Parameters = [
"selection": [
"selectionType": "registered",
"selectionMatch": ""
]
]
let headers: HTTPHeaders = [
"Content-Type": "text/json",
"Authorization": "Bearer \(core.accessToken)"
]
let req = AF.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
.responseJSON { response in
print("Error:", response.error?.localizedDescription ?? "no error")
print("Data:", String(data: response.data!, encoding: .utf8)!)
}
debugPrint(req)
}
When I run this, the call ultimately fails with status code 408, a server timeout.
When I change the HTTP method to use .post, the call completes, but the response is an internal status 3 with message "Update failed due to a communication error."
Can anyone help me figure out what I'm doing wrong before I waste another day trying to hack my way through it?
Ecobee's request format is a bit bizarre, as it uses form encoded parameters, but one of the values is a JSON encoded body. You'll have to do a little bit of prep work, as Alamofire doesn't naturally support something like this. This is just sample code, you'll need to do the work to make it safer.
First, encode the JSON parameters and get the String value:
let jsonParameters = ["selection": ["selectionType": "registered", "selectionMatch": ""]]
let jsonData = try! JSONEncoder().encode(jsonParameters)
let jsonString = String(decoding: jsonData, as: UTF8.self)
Then, create the actual parameters and headers values:
let parameters = ["format": "json", "body": jsonString]
let token = "token"
let headers: HTTPHeaders = [.authorization(bearerToken: token), .contentType("text/json")]
let url = URL(string: "https://api.ecobee.com/1/thermostat")!
And make the request:
AF.request(url, parameters: parameters, headers: headers).responseJSON { response in ... }
In every one of my two calls to loadHeader with the same URL, I get "The request timed out" error. In first try, the function works and I manage to get and parse the response. In second, I get time out. In third it works and in forth time out again. Is it about my code or about server? I tried waiting before trying again as it might be some security protocol of server but it didn't change anything.
Here is error code:
FAILURE: Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."
And here is my code:
func loadHeader(url: String){
let parameters = ["foo": "bar"]
Alamofire.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default)
.validate { request, response, data in
// Custom evaluation closure now includes data (allows you to parse data to dig out error messages if necessary)
return .success
}
.responseJSON {
response in
let json=response.data
self.jsonToObjectHeader(json: json!)
}
}
func jsonToObjectHeader(json:Data){
do{
databases = try JSONDecoder().decode(responseHeader.self,from: json)
if databases.ordersHeader.count == 0 {
let alert = UIAlertView(title: "empty",message: "empty",delegate: nil,cancelButtonTitle: "OK")
alert.show()
}
else {
for i in 0...databases.ordersHeader.count-1 {
myArray2.append(databases.ordersHeader[i].productName!)
}
}
DispatchQueue.main.async {
self.myTableView.reloadData()
self.myTableView.tableFooterView = UIView()
}
//print(databases.ordersHeader[0].companyAddress)
}catch let jsonErr {
print(jsonErr)
}
}
I've added
let parameters = ["foo": "bar"]
thinking I've to give parameters as it is in the function. Just updated
Alamofire.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default)
to
Alamofire.request(url, method: .get, parameters: nil, encoding: JSONEncoding.default)
and it solved the issue. Posting this in case of someone experiences something similar.
I am trying to send a POST request with Alamofire 4.6.0 and the request is not firing, when I debug it, it shows that Alamofire is building the request but it does not seem like it is sending the request.
This code is nested in a method that has a completion handler.
func phoneVerifyStart(Step: Bool, PhoneNumber: String, authCode: String?, completionHandler: #escaping (_ response: Any? ->()){
//Create our request with the users phone number
let jsonData = ["request": ["method": "phoneNumberVerificationStart","id": 1, "params": ["number": "\(PhoneNumber)"] ]]
let urlString = “************************************”
Alamofire.request(requestURL, method: .post, parameters: jsonData, encoding: JSONEncoding.default).responseJSON { response in
print("here")
completionHandler(response)
}
}
I am not getting any response at all, I am also not able to hit the "here".
The server does not receive a call from this code so the code is not sending a request at all.
I am using Alamofire to make a post request to server. The post request is working fine.
Issue: When the post request is made, it returns some data which I need. How can I store/ retrieve that data
The POST Request:
Alamofire.request(.POST, postURL, parameters: params)
to get the response closure add
.response { request, response, data, error in }
to the end of your code
ie
Alamofire.request(.POST, "http://httpbin.org/get", parameters: ["foo": "bar"])
.response { request, response, data, error in
print(request)
print(response)
print(data)
print(error)
}
If you are using the latest version of AlamoFire.
If you are using the latest version of AlamoFire.
Try this working fine for me.(Change request arguments based on your need)
let url1 = "http://yoururl.com"
let head = [ "Accept": "application/json;charset=UTF-8",
"Content-Type": "application/json;charset=UTF-8"] // Adding headers
let p = ["Email":"anything","Password": "123"] // Adding parameters if any
Alamofire.request(.POST,url1, parameters: p, encoding : .JSON, headers : head)
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
}
