iOS调用Laravel接口返回错误信息

iOS端代码如下:

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;

}];

Laravel的代码如下:

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]);

}

提示错误：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.}

但是将Route::post 改成 Route::get

manage POST:@"login/signin" 改成 manage GET:@"login/signin"

可以返回数据如下：

{

code = 0;

data = {

password = 123456;

phone = 13800138000;

};

message = "\U767b\U5f55\U6210\U529f";

}

请问问题出在哪里，求帮助，谢谢各位:D 。

使用Paw查看POST数据会出现php错误如下：

Deprecated: Automatically populating $HTTP_RAW_POST_DATA is

deprecated and will be removed in a future version. To avoid this

warning set 'always_populate_raw_post_data' to '-1' in php.ini and

use the php://input stream instead. in Unknown on line 0

Warning: Cannot modify header information

- headers already sent in Unknown on line 0
