Laravel:使用多列进行身份验证 [英] Laravel: Using multiple columns for authentication

问题描述

我有一个Laravel 6应用程序.

I have a Laravel 6 application.

在典型的应用程序中，用户只需指定自己的 email ，其中电子邮件是唯一的.

In a typical application, the user would just specify their email, where the email is unique.

但是，在我的应用程序中，用户模型中有2列用于验证用户身份.

However, in my application, I have 2 columns in the User model that is used to authenticate users.

• app_id
• 电子邮件
• 唯一(app_id，电子邮件)

因此，要登录，我们需要同时传递 app_id 和 email 以及 password .相同的 email 可以用于不同的 app_id s.

So in order to login, we need to pass both an app_id and an email, along with the password. The same email could be used across different app_ids.

我将如何实现?

推荐答案

Auth :: routes()提供的默认登录操作如下:

The default login actions provided by Auth::routes() are the following:

Route::get('login', 'Auth\LoginController@showLoginForm')->name('login');
Route::post('login', 'Auth\LoginController@login');

这是默认的 login 函数，是 LoginController 使用的 AuthenticatesUsers 特性的一部分:

This is the default login function, part of the AuthenticatesUsers trait used by the LoginController:

    /**
     * Handle a login request to the application.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Http\Response|\Illuminate\Http\JsonResponse
     *
     * @throws \Illuminate\Validation\ValidationException
     */
    public function login(Request $request)
    {
        $this->validateLogin($request);

        // If the class is using the ThrottlesLogins trait, we can automatically throttle
        // the login attempts for this application. We'll key this by the username and
        // the IP address of the client making these requests into this application.
        if (method_exists($this, 'hasTooManyLoginAttempts') &&
            $this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        if ($this->attemptLogin($request)) {
            return $this->sendLoginResponse($request);
        }

        // If the login attempt was unsuccessful we will increment the number of attempts
        // to login and redirect the user back to the login form. Of course, when this
        // user surpasses their maximum number of attempts they will get locked out.
        $this->incrementLoginAttempts($request);

        return $this->sendFailedLoginResponse($request);
    }

有几种方法可以解决这个问题.

There are a few ways to approach this.

# app/Http/Controllers/Auth/LoginController.php

    public function login(Request $request)
    {
        // add more stuff like validation, return the view you want, etc.
        // This is barebones
        auth()->attempt($request->only(['app_id', 'login', 'password']);
    }

选项2:覆盖 LoginController

中的 validateLogin 和 credentials 函数

# app/Http/Controllers/Auth/LoginController.php

    protected function validateLogin(Request $request)
    {
        $request->validate([
            'app_id' => 'required|string',
            'email' => 'required|string',
            'password' => 'required|string',
        ]);
    }

    /**
     * Get the needed authorization credentials from the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    protected function credentials(Request $request)
    {
        return $request->only('app_id', 'email', 'password');
    }
