Request method 'POST' not supported

Hi,

how can i execute in swift a web service that was build in java ?

the url is http://52.30.114.86:8080/mimosms/v1/user/login?username=xxxx&password=5555

The service works fine in my browser, but when i try to run in xcode i receive the message : Optional({"errors":["Request method 'POST' not supported"]})

below the code :

            let url:NSURL = NSURL(string: "http:/
            let session = NSURLSession.sharedSession()
           
            let request = NSMutableURLRequest(URL: url)
            request.HTTPMethod = "POST"
            request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringCacheData
           
            let paramString = "login?username=xxxx&password=5555"
            request.HTTPBody = paramString.dataUsingEncoding(NSUTF8StringEncoding)
           
            let task = session.dataTaskWithRequest(request) {
                (
               
                let data, let response, let error) in
               
                guard let _:NSData = data, let _:NSURLResponse = response  where error == nil else {
                   
                    print("error")
                   
                    return
                }
               
                let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)
                print(dataString)
               
            }
           
            task.resume()
           
       
    }

what could be wrong in the code ?
