jquery - Laravel 5.3 Ajax 登录

Question

我正在尝试使用新的 Laravel 5.3 项目使用 ajax 登录我的用户。

我已经生成了身份验证路由，并将其添加到我的 web.php 中:

Auth::routes();

我有一个包含电子邮件、密码输入和 csrf 字段的 html 表单。然后我还有这个 javascript 文件:

$("form.login").submit(function(e) {
    e.preventDefault();

    $.ajax({   
        method: "POST",
        dataType: "json",
        headers: { 
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
        },
        data: $("form.login").serialize(),
        url: "/login"
    })
    .done(function(data) {
        console.log(data);
    });
});

但是，当我发布它时，它会显示在我的网络选项卡中:

它重定向回原始页面，不返回任何数据。

为什么要这样做？ 5.3 不再提供 json 响应了吗？

完整的解决方案:

嗨，赖尼尔科斯，

我也尝试对5.3版本做同样的事情，我终于解决了它:)并且解决方案非常干净。

首先，我在App\Http\Controllers\Api下 创建了一个名为 Auth的新文件夹，我这样做只是为了添加新的身份验证api 的 Controller ，以便我可以重写一些函数，然后我将身份验证 Controller ( LoginController、 ForgotPasswordController、 RegisterController)复制到这个新文件夹。

在 LoginController 类中:我重写了进行重定向的函数。

The first function: will be automatically called when theauthentication return success.

The second function: will be automatically called when theauthentication return error.

The last function: will be automatically called when the user has beenlocked out after trying 5 login attempts.

     /**
     * Send the response after the user was authenticated.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    protected function sendLoginResponse(Request $request) {
        $this->clearLoginAttempts($request);

        return response()->json(['SUCCESS' => 'AUTHENTICATED'], 200);
    }

    /**
     * Get the failed login response instance.
     *
     * @return \Illuminate\Http\Response
     */
    protected function sendFailedLoginResponse() {
        return response()->json(['ERROR' => 'AUTH_FAILED'], 401);
    }

    /**
     * Error after determining they are locked out.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    protected function sendLockoutResponse(Request $request) {
        $seconds = $this->limiter()->availableIn(
            $this->throttleKey($request)
        );

        return response()->json(['ERROR' => 'TOO_MANY_ATTEMPTS', 'WAIT' => $seconds], 401);
    }

在 RegisterController 类中:我重写了进行重定向的函数。

In the first function: I modified the validator response to return a more comfortable response (array) to work with.

The second function: will be automatically called when the registration return success.

    /**
     * Handle a registration request for the application.
     *
     * @param Request $request
     * @return \Illuminate\Http\Response
     */
    public function register(Request $request) {
        $validator = $this->validator($request->all());

        if($validator->fails())
            return response()->json(['ERROR' => $validator->errors()->getMessages()], 422);

        event(new Registered($user = $this->create($request->all())));

        $this->guard()->login($user);

        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
    }

    /**
     * The user has been registered.
     *
     * @param Request $request
     * @param  mixed $user
     * @return mixed
     */
    protected function registered(Request $request, $user) {
        return response()->json(['SUCCESS' => 'AUTHENTICATED']);
    }

在 ForgotPasswordController 类中:我重写了进行重定向的函数。

I modified the reset link email function so we can get the messages and display as json instead of the redirects.

     /**
     * Send a reset link to the given user.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse
     */
    public function sendResetLinkEmail(Request $request)
    {
        $validator = Validator::make($request->only('email'), [
            'email' => 'required|email',
        ]);

        if ($validator->fails())
            return response()->json(['ERROR' => 'VALID_EMAIL_REQUIRED'], 422);

        // We will send the password reset link to this user. Once we have attempted
        // to send the link, we will examine the response then see the message we
        // need to show to the user. Finally, we'll send out a proper response.
        $response = $this->broker()->sendResetLink(
            $request->only('email')
        );

        if ($response === Password::RESET_LINK_SENT) {
            return response()->json(['SUCCESS' => 'EMAIL_SENT'], 200);
        }

        // If an error was returned by the password broker, we will get this message
        // translated so we can notify a user of the problem. We'll redirect back
        // to where the users came from so they can attempt this process again.
        return response()->json(['ERROR' => 'EMAIL_NOT_FOUND'], 401);
    }
