登录时为什么不需要指定 guard 看守

默认 web 看守
参考一下：

guard() method

Illuminate/Auth/AuthManager.php

    /**
     * Attempt to get the guard from the local cache.
     *
     * @param  string  $name
     * @return \Illuminate\Contracts\Auth\Guard|\Illuminate\Contracts\Auth\StatefulGuard
     */
    public function guard($name = null)
    {
        $name = $name ?: $this->getDefaultDriver();
        return $this->guards[$name] ?? $this->guards[$name] = $this->resolve($name);
    }

    /**
     * Get the default authentication driver name.
     *
     * @return string
     */
    public function getDefaultDriver()
    {
        return $this->app['config']['auth.defaults.guard'];
    }

config/auth.php

   'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],
