在 Laravel 的 ajax JQUERY 请求中找到 302

Question

我在 Laravel 中使用 ajax 请求并传递 CSRF 令牌，但有时我的应用程序卡住并收到此错误：

代码：

  var formData = $(this).serialize();
    $.ajaxSetup({
        header:$('meta[name="_token"]').attr('content')
    });
    $.ajax({
        url:$(this).attr('action'),
        type:'POST',
        data:formData,
        headers: {
            Accept: "application/json"
        },
        success:function(response) {

此表单在模态弹出窗口中：

 <form id="user-login" class="login" action="{{ url('login') }}" method="post">
 {{ csrf_field() }}

控制器：

  public function login(Request $request)
    {  
        $validator = Validator::make($request->all(),[
            'email' => ['required'],
            'password' => ['required', 'string', 'min:5'],
        ]);
        if ($validator->passes()) {
        if (\Auth::guard('user')->attempt(['email' => $request->email, 'password' => $request->password, 'status' => 'active','isAdmin'=>'0']) || \Auth::guard('user')->attempt(['contact_number' => $request->email, 'password' => $request->password, 'status' => 'active','isAdmin'=>'0'])) {
            $request->session()->regenerate();
            return response(['success' => true,'message'=>'Successfully Login'], 200);
         }
        else
        {
            $message = 'Invalid username or password';
            return response()->json(['success'=>false,'message' => $message]);
        }
    }
    return Response::json(['errors' => $validator->errors()]);
    }

路线：

Route::post('/user-login', 'Auth\UserRegisterController@login')->name('user-login');

RedirectIfAuthenticated 中间件：

 public function handle($request, Closure $next, $guard = null)
    {
        if ($guard == "employee" && Auth::guard($guard)->check()) {
                return redirect(RouteServiceProvider::EMPLOYEE_HOME);
        }

        if (Auth::guard($guard)->check()) {
            return redirect(RouteServiceProvider::HOME);
        }

        return $next($request);
    }

任何解决方案，谢谢

修改控制器中的返回

return response(['success' => true,'message'=>'Successfully Login'], 200);

到

return response->json(['success' => true,'message'=>'Successfully Login'], 200);

你应该尝试几件事。

1. 这可能是由于外部组的中间件正在重定向请求

2. 您对此的 ajax 设置。确保你拿到了令牌

   $.ajaxSetup({ headers: { 'X-CSRF-TOKEN': '<?= csrf_token() ?>' } });

3. 确保正确返回响应。

   return response(['status' => true, 'message' => 'Success']);
