将 laravel 从 5.5 更新到 5.7 时出错（未定义 class 常量“HEADER_CLIENT_IP”）

Question

我收到这个错误。

未定义 class 常量“HEADER_CLIENT_IP”脚本@php artisan package：发现处理返回错误代码 1 的自动加载转储后事件

我变了

app\Http\Middleware\TrustedProxies.php by:

    <?php

  namespace App\Http\Middleware;

  use Illuminate\Http\Request;
  use Fideloper\Proxy\TrustProxies as Middleware;

  class TrustProxies extends Middleware
  {
    protected $proxies;
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
  }

这是 my.composerjson 文件

    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",

    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    } }

我仍在处理同样的错误。 大佬能看出来问题出在哪里吗？

Answer 1

在composer.json更改fideloper / proxy

从

"fideloper/proxy": "~3.3",

至

"fideloper/proxy": "^4.0",

在那之后

composer update

Answer 2

如果你们在更新到 laravel 9.0 时遇到此错误，请从 composer.json 中删除以下代码行

"fideloper/proxy": "^4.4.1",

并在终端运行 composer update 命令

composer update

然后，更改use Fideloper\Proxy\TrustProxies as Middleware; use Illuminate\Http\Middleware\TrustProxies as Middleware; 在文件app\Http\Middleware\TrustProxies.php file

Answer 3

1）将您的composer.json更改为以下内容

"php": ">=7.1.3",
"fideloper/proxy": "^4.0",
"laravel/framework": "5.7.*",
"laravel/tinker": "~1.0",

2）将您的App \\ Http \\ Middleware \\ TrustProxies.php更改为以下内容

<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Fideloper\Proxy\TrustProxies as Middleware;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array|string
     */
    protected $proxies;
    /**
     * The headers that should be used to detect proxies.
     *
     * @var int
     */
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
}

3）从配置目录中删除名称为trustedproxy.php的文件（如果存在）

4）从您的应用程序目录在控制台中运行以下命令

composer update

5）此步骤不是必需的，但是它将清除所有缓存和自动加载文件

php artisan clear-compiled

composer dump-autoload

php artisan cache:clear

php artisan config:clear

php artisan view:clear

Answer 4

您是否尝试更新作曲家

composer update

并转储自动加载？

composer dump-autoload
