iOS calls Laravel interface returns error message

The iOS port code is as follows:

Afhttprequestoperationmanager *manage = [[Afhttprequestoperationmanager alloc]initwithbaseurl:[nsurl URLWithString: @ "Http://localhost:8000/login/signin"]];manage.requestserializer = [Afjsonrequestserializer serializer]; Manage.responseserializer = [Afjsonresponseserializer serializer]; [Manage.requestserializer setvalue:@ "Application/json" forhttpheaderfield:@ "Accept"]; Manage.responseSerializer.acceptableContentTypes = [Nsset setwithobjects:@ "Application/json", @ "Text/plain", @ "text /javascript ", @" Text/json ", @" text/html ", nil]; [Manage post:@ "Login/signin" Parameters:[self.mylogin Toparams] success:^ (afhttprequestoperation *operation, ID        Responseobject) {Debuglog (@ "\n===========response===========\n%@:\n%@", @ "Login/signin", responseObject);        [_activityindicator stopanimating];    _loginbutton.enabled = YES; } failure:^ (Afhttprequestoperation *operation, Nserror *error) {Debuglog (@ "\n===========response===========\n%@:\n        %@ ", @" Login/signin ", error); [_Activityindicator stopanimating];    _loginbutton.enabled = YES; }];

The code for Laravel is as follows:

routes.php----------Route::post('login/signin',[    'as'=>'signin','uses'=>'Login\LoginController@signin']);LoginController.php----------public function signin(){      $message = "登录成功";    $data = array('phone'=>'13800138000','password'=>'123456');    $code = 0;    return response()->json(['message'=>$message,'data'=>$data,'code'=>0]);}

Prompt error:Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x7fe00d90a3a0 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

But change the Route::p OST to Route::get

Manage post:@ "Login/signin" changed to manage get:@ "Login/signin"

You can return data as follows:

{    code = 0;    data =     {        password = 123456;        phone = 13800138000;    };    message = "\U767b\U5f55\U6210\U529f";}
