Laravel5.5升级碰到5.6的问题

如果你在laravel5.5 升级到laravel5.6之后出现这个错误，打开app\Http\Middleware\TrustProxies.php

更改以下内容

protected $headers = [
    Request::HEADER_FORWARDED => ‘FORWARDED‘,
    Request::HEADER_X_FORWARDED_FOR => ‘X_FORWARDED_FOR‘,
    Request::HEADER_X_FORWARDED_HOST => ‘X_FORWARDED_HOST‘,
    Request::HEADER_X_FORWARDED_PORT => ‘X_FORWARDED_PORT‘,
    Request::HEADER_X_FORWARDED_PROTO => ‘X_FORWARDED_PROTO‘,
];

修改为

protected $headers = Request::HEADER_X_FORWARDED_ALL;
