当我尝试使用错误的凭据登录时，我收到此错误：

<!doctype html>

I want to receive JSON response like this in Postman : 
{
  "error":"invalid username or password"
}

api.php文件的内容：

Route::post('user/register','APIRegisterController@register');

Route::post('user/login','APILoginController@login');

Route::middleware('jwt.auth')->get('/users', function (Request $request) {
    return auth()->user();
});

Route::middleware('jwt.auth')->group( function(){
   Route::resource('/cars', 'API\CarController');
} );

我发现问题出在我作为数组传递的错误消息编号中

return response()->json(['error'=>'invalid username or password'], [401]);

我应该去掉括号，像int一样传递它

return response()->json(['error'=>'invalid username or password'], 401);

请更改此选项，并尝试同时捕获两个

try {
            if(! $token = JWTAuth::attempt($credentials))
            {
                return response()->json(['error'=>'invalid username or password'], 401);
            }
        } catch (JWTException $e) {
            //throw $th;
            return response()->json(['error'=>'could not create token'], 500);
        }

这就是我在拉雷维尔的做法

return Response::json(['message' => $value,'other_info'=>$vlue2],201);

或使用辅助函数：

return response()->json(['message' => $value,'other_info'=>$vlue2], 201);

您需要从PostMani发送一个POST请求。如果您要发布route.php或api.php的内容，那么它将非常有用file@SalimDjerbouh我确实发送了一个POST请求，这是我发送时收到的it@jobvink我在上面添加了api.php文件，但我不知道在哪里可以找到route.phpfile@SalimDjerbouh我用POST替换了我得到的错误要求

return response()->json(['message' => $value,'other_info'=>$vlue2], 201);
