laravel微信授权登录

微信登录通常是通过OAuth2.0来授权的。

客户端向微信服务端发起请求获取code；
获取到code后向服务端发起请求登录，
服务端通过code向微信服务器换取网页授权access_token和用户的openID，
再通过access_token获取用户信息，保存到服务端。

laravel中微信登录有集成的扩展，
socialiteproviders

安装扩展

composer require socialiteproviders/weixin

配置
app/Providers/EventServiceProvider.php

protected $listen = [
    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
        // add your listeners (aka providers) here
        'SocialiteProviders\Weixin\WeixinExtendSocialite@handle'
    ],
];

    'client_id' => env('WEIXIN_KEY'),
    'client_secret' => env('WEIXIN_SECRET'),
