Perform Anfrage POST in Swift

Question

Ich versuche, so etwas zu tun:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://google.com"]]; 

request.HTTPMethod = @"POST"; 

NSString *stringData = @"some data"; 
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding]; 
request.HTTPBody = requestBodyData; 

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 

Dies ist, was so weit ich habe:

var url = NSURL(string: "some url") 
var request = NSMutableURLRequest(URL: url) 
request.HTTPMethod = "POST" 

var dataString = "some data" 
var requestBodyData: NSData = dataString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding) as NSData 

request.HTTPBody = requestBodyData 

var connection = NSURLConnection(request: request, delegate: self, startImmediately: false) 

println("sending request...") 

connection.start() 

jedoch die var requestBodyData: Linie wirft den ersten Stein with "Kann den Typ NSData des Ausdrucks nicht in den Datentyp NSData konvertieren"

Wer sollte schon wiegen?

Answer 1

stringByAddingPercentEscapesUsingEncoding gibt eine Zeichenfolge anstelle eines NSData-Objekts zurück. Nach this Antwort, müssen Sie dies zu einer NSData Instanz zu konvertieren verwenden:

let data = (anySwiftString as NSString).dataUsingEncoding(NSUTF8StringEncoding) 

Answer 2

Alamofire über die HTTP-POST-Anforderung wie

let request = NSMutableURLRequest(URL: NSURL(string: "https://www.google.com")!) 
request.HTTPMethod = "POST" 

let body = "email=\(email)&access_token=\(token)" 
request.HTTPBody = body.dataUsingEncoding(NSUTF8StringEncoding) 

Alamofire.request(request).responseJSON { response in 

     NSLog("response.request: \(response.request)") // original URL request 
     NSLog("esponse.response: \(response.response)") // URL response 

     switch response.result { 
     case .Success: 
      NSLog("Validation Successful") 
     case .Failure(let error): 
      // Logout 
      NSLog("\(error), \(String(data: response.data!, encoding: NSUTF8StringEncoding))") 
      return 
     } 

     // Save sip account information to NSUserdefaults 
     if let json = response.result.value as? [String: AnyObject]{ 
      // Do your stuff 
     } 
}
