iOS : http Post using swift - ios

Question

I figured it out solution at the bottom
I am trying to make an HTTP post request to my server. Here's what I did
var request : NSMutableURLRequest = NSMutableURLRequest(URL : NSURL(string : "myURL")
let session : NSURLSession = NSURLSession.sharedSession()
request.allHTTPHeaderFields = (headers as [NSObject : AnyObject])
request.HTTPShouldHandleCookies = true
request.HTTPMethod = "POST"
var postData = "frontend=iOS"
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
NSHTTPCookieStorage.sharedHTTPCookieStorage().cookieAcceptPolicy = NSHTTPCookieAcceptPolicy.Always
println(request.allHTTPHeaderFields)
println(request.HTTPBody)
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
let json:JSON = JSON(data: data)
println(json)
onCompletion(json, error)
})
task.resume()
this is not setting the HTTPRequest.POST
I tried printing the request to the server on the server side. IT said post was empty
POST : [QueryDict : {}]
What am I missing here? Any help is appreciated
Solution :
I mistakenly set the content-value to application/json when in fact it
was not a json body. Removing it solved the problem

Answer 1

use https://github.com/Alamofire/Alamofire
easy networking :)
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.response { (request, response, data, error) in
println(request)
println(response)
println(error)
}
you can use all of the below.
public enum Method: String {
case OPTIONS = "OPTIONS"
case GET = "GET"
case HEAD = "HEAD"
case POST = "POST"
case PUT = "PUT"
case PATCH = "PATCH"
case DELETE = "DELETE"
case TRACE = "TRACE"
case CONNECT = "CONNECT"
}

Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs
var url = NSURL(string: urlstring)
var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)
See How to escape the HTTP params in Swift on the way to correctly encode key-value pairs into the data string.
