authentication - How to make 'post' HTTP request in Swift? -


i've log in page in app in i'm doing authentication , making post request. i'll grabbing token api i'm provided with. however, code isn't printing on print log. please help!!

    @ibaction func submit(sender: anyobject) {    //creating function connect api             func connecttowebapi(){    //setting base64-encoded credentials           let username = "user"           let password = "pass"           let loginstring = nsstring(format: "%@:%@", username, password)           let logindata: nsdata = loginstring.datausingencoding(nsutf8stringencoding)!           let base64loginstring = logindata.base64encodedstringwithoptions(nil)    //creating request           let url = nsurl(string: "http://www.telize.com/geoip")          var request = nsmutableurlrequest(url: url!)           let config = nsurlsessionconfiguration.defaultsessionconfiguration()           let session = nsurlsession.sharedsession()           request.addvalue("application/json", forhttpheaderfield: "content-type")           request.addvalue("application/json", forhttpheaderfield: "accept")            let urlconnection = nsurlconnection(request: request, delegate: self)           request.httpmethod = "post"           request.setvalue(base64loginstring, forhttpheaderfield: "authorization")             let task = session.datataskwithurl(url!, completionhandler: {data, response, error -> void in           if (error != nil) {                       println(error)            }           else {    // converting data dictionary            let jsonresult = nsjsonserialization.jsonobjectwithdata(data, options: nsjsonreadingoptions.mutablecontainers, error: nil) as! nsdictionary            println(jsonresult)                    }               })     //fire off request            task.resume()            }

a couple of issues:

  1. first, you're using both nsurlconnection , nsurlsession. means you're performing request twice. nowadays, nsurlconnection being deprecated soon, should eliminate nsurlconnection portion of code snippet , use nsurlsession.

  2. second, when parsing json, you've explicitly told not report error (you set error parameter nil). should @ error, if any:

    var parseerror: nserror? if let jsonresult = nsjsonserialization.jsonobjectwithdata(data, options: nsjsonreadingoptions.mutablecontainers, error: &parseerror) as? nsdictionary {     println("jsonresult = \(jsonresult)")   } else {      // if didn't work, show enough can figure out why:      println("parseerror = \(parseerror)")     println("response = \(response)")     let responsestring = nsstring(data: data, encoding: nsutf8stringencoding)     println("responsestring = \(responsestring)") // html server describing problem in request }

usually these sorts of requests fail because of wrong how original nsurlrequest created, not showing enough information source of problem.
