Laravel5.5学习笔记之框架自带API Token认证

框架自带Token认证

• 1. 需要在用户表加api_token字段

• 2.路由配置

登录注册等省略，详细参考文档
https://laravelacademy.org/post/9153.html#toc_12

• 3. 配置需要认证的路由

Route::group(['middleware'=>'auth:api'],function(){
    Route::any('user', function (Request $request) {
        return $request->user();
    });
});

上面需要认证通过，才能拿到用户的Token信息

['middleware'=>'auth:api'] 这段配置的意思：

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
    ],

路由中间件： 'auth' => IlluminateAuthMiddlewareAuthenticate::class, 对应的配置文件 auth.php auth.guards.api

dirver 文件是token 对应的是框架的：

　vendor/laravel/framework/src/Illuminate/Auth/TokenGuard.php

   vendor/laravel/framework/src/Illuminate/Auth/Middleware/Authenticate.php

获取Token 的方法，从header里面获取

  public function getTokenForRequest()
    {

        $token = $this->request->query($this->inputKey);
        if (empty($token)) {
            $token = $this->request->input($this->inputKey);
        }
        if (empty($token)) {
            $token = $this->request->bearerToken();
        }
        if (empty($token)) {
            $token = $this->request->getPassword();
        }

        return $token;
    }

    /**
     * Get the bearer token from the request headers.
     *
     * @return string|null
     */
    public function bearerToken()
    {
        $header = $this->header('Authorization', '');

        if (Str::startsWith($header, 'Bearer ')) {
            return Str::substr($header, 7);
        }
    }

由此可知框架从header里面获取默认的字段是Authorization ,且字段值是 Bearer api_token,如下图

开始没有看源码测试了 api_toke, token,Authorization 都试过不可以（其实Authorization 这个是可以的）

不可以的原因是因为,路由配置是get请求，结果代码里面是post请求导致路由异常

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException

访问用户

https://laravelacademy.org/post/9153.html#toc_12
$request->user() 或 Auth 门面访问当前用户：
Auth::guard('api')->user(); // 登录用户实例
Auth::guard('api')->check(); // 用户是否登录
Auth::guard('api')->id(); // 登录用户ID

Location of auth:api Middleware

It's not a good idea to edit vendor files
