Answer 1

上面那位同事的回答，原则上是对的。只是他忘了提到，在文件中进行所有更改后，您需要删除该包fideloper/proxy：

https://laravel.com/docs/9.x/upgrade

可信代理

影响的可能性：低

如果您通过将现有应用程序代码导入全新的 Laravel 9 应用程序框架来将 Laravel 8 项目升级到 Laravel 9，则可能需要更新应用程序的“可信代理”中间件。

在您的app/Http/Middleware/TrustProxies.php文件中，更新use Fideloper\Proxy\TrustProxies as Middleware为use Illuminate\Http\Middleware\TrustProxies as Middleware.

接下来，在 中app/Http/Middleware/TrustProxies.php，您应该更新$headers属性定义：

// Before...
protected $headers = Request::HEADER_X_FORWARDED_ALL;

// After...
protected $headers =
   Request::HEADER_X_FORWARDED_FOR |
   Request::HEADER_X_FORWARDED_HOST |
   Request::HEADER_X_FORWARDED_PORT |
   Request::HEADER_X_FORWARDED_PROTO |
   Request::HEADER_X_FORWARDED_AWS_ELB;

fideloper/proxy最后，您可以从应用程序中删除Composer 依赖项：

composer remove fideloper/proxy

Answer 2

如果您通过将现有应用程序代码导入全新的 Laravel 9 应用程序框架来将 Laravel 8 项目升级到 Laravel 9，则可能需要更新应用程序的“可信代理”中间件。

在您的app/Http/Middleware/TrustProxies.php文件中，更新：

use Fideloper\Proxy\TrustProxies as Middleware

到

use Illuminate\Http\Middleware\TrustProxies as Middleware

接下来，在 中app/Http/Middleware/TrustProxies.php，您应该更新$headers属性定义：

// 前...

protected $headers = Request::HEADER_X_FORWARDED_ALL;

// 后...

protected $headers =
    Request::HEADER_X_FORWARDED_FOR |
    Request::HEADER_X_FORWARDED_HOST |
    Request::HEADER_X_FORWARDED_PORT |
    Request::HEADER_X_FORWARDED_PROTO |
    Request::HEADER_X_FORWARDED_AWS_ELB;

然后运行composer update

确保您使用的是 PHP 8.0

Answer 3

如果上述答案对您不起作用并且您遇到相同的错误，请再执行一行以从composer.json 中删除 fideloper/proxy。

// Before...
protected $headers = Request::HEADER_X_FORWARDED_ALL;
 
// After...
protected $headers =
    Request::HEADER_X_FORWARDED_FOR |
    Request::HEADER_X_FORWARDED_HOST |
    Request::HEADER_X_FORWARDED_PORT |
    Request::HEADER_X_FORWARDED_PROTO |
    Request::HEADER_X_FORWARDED_AWS_ELB;

这将从composer.json中删除代理，并且异常将消失。

composer remove fideloper/proxy

laravel 9 升级指南中正确提到了这一点。 https://laravel.com/docs/9.x/upgrade#the-assert-deleted-method
