Error Domain=NSURLErrorDomain Code=-1017 "cannot parse response"

Question

Here I am getting error while I post json.

Error Domain=NSURLErrorDomain Code=-1017 "cannot parse response" UserInfo=0x7f89dac01a40 {NSUnderlyingError=0x7f89e0277a20 "cannot parse response", NSErrorFailingURLStringKey=http://test-onboard.qlc.in/FieldSense/authenticate, NSErrorFailingURLKey=http://test-onboard.qlc.in/FieldSense/authenticate, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-1, NSLocalizedDescription=cannot parse response}

Here is my code:

NSDictionary *dictionaryData=[[NSDictionary alloc]initWithObjectsAndKeys:self.txtUsername.text, @"userEmailAddress", self.txtPassword.text, @"password",nil];            
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:dictionaryData options:kNilOptions error:&error];

[request setURL:url];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:jsonData];

Answer 1

I am also getting this error but i overcome this by adding a line

request.HTTPMethod = "POST"

for Objective-C programming use this:

[request setHTTPMethod:@"POST"];

Answer 2

I had the same problem with Alamofire and the error caused this:

let encoding = Alamofire.ParameterEncoding.JSON let (encodedRequest, _) = encoding.encode(URLRequest, parameters: params)

my variable params was dict [:]. I changed to parameters: nil and it's work.
