如果在授权标头中找不到它，我特别试图让 Sanctum 的 Guard 类在 JSON 请求正文中查找 API 令牌。我只需要在检查承载令牌后添加一个 elseif。
所以问题是：在不触及原始 Sanctum 文件的情况下，用我自己的方法（或类）覆盖此方法（或类）的最佳方法是什么？
<?php

use Illuminate\Http\Request;

/**

*
* @var int
*/
protected $expiration;
/**
* Create a new guard instance.

* @param \Illuminate\Contracts\Auth\Factory $auth
* @param int $expiration
* @return void
*/
public function __construct(AuthFactory $auth, $expiration = null)
{
$this->auth = $auth;
$this->expiration = $expiration;
}
/**

*/
public function __invoke(Request $request)
{
if ($user = $this->auth->guard('web')->user()) {
return $this->supportsTokens($user)
? $user->withAccessToken(new TransientToken)
: $user;
}
if ($token = $request->bearerToken()) {
$model = Sanctum::$personalAccessTokenModel;
$accessToken = $model::where('token', hash('sha256', $token))->first();
if (! $accessToken ||
($this->expiration &&
$accessToken->created_at->lte(now()->subMinutes($this->expiration)))) {
return;
}
return $this->supportsTokens($accessToken->tokenable) ? $accessToken->tokenable->withAccessToken(
tap($accessToken->forceFill(['last_used_at' => now()]))->save()
) : null;
}
}
