The Laravel code is as follows:

Routes. php ---------- Route: post ('login/signin', ['as' => 'signature', 'uses '=> 'login \ LoginController @ signin']); LoginController. php ---------- public function signin () {$ message = "Logon successful"; $ data = array ('phone' => '000000', 'Password' => '000000 '); $ code = 0; return response ()-> json (['message' => $ message, 'data' => $ data, 'code' => 0]);}

Error message: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.}

However, change Route: post to Route: getmanage POST: @ "login/signin" to manage GET: @ "login/signin"

You can return the following data:

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

Where is the problem? Could you help me? Thank you: D.

When you use Paw to view POST data, the following php error occurs:

Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid thiswarning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0Warning: Cannot modify header information - headers already sent in Unknown on line 0

Phpinfo () knows always_populate_raw_post_data and changes it to-1.
