问题描述

我正在尝试将我的 Laravel 5.5 升级到 5.6. 我已经按照 laravel 网站，但我收到此错误:

I am trying to upgrade my Laravel 5.5 to 5.6. I have followed the instructions from the laravel website, yet I got this error:

Your requirements could not be resolved to an installable set of packages.
    Problem 1
        - The requested package laravel/framework 5.6.* is satisfiable by laravel/framework[5.6.x-dev] but these conflict with your requirements or minimum-stability.

因此，我更改了我的 composer.json 文件并添加了 2 行:**"minimum-stability": "dev", "prefer-stable": true,** 基于 this laracast 讨论.

So, I changed my composer.json file and added 2 lines: **"minimum-stability": "dev", "prefer-stable": true,** based on the first answer on this laracast discussion.

一切似乎都很好，直到出现另一个错误:

Everything seemed to be working just fine until I got another error:

Loading composer repositories with package information

Writing lock file
Generating optimized autoload files
> IlluminateFoundationComposerScripts::postAutoloadDump
> @php artisan package:discover

In trustedproxy.php line 66:

  Undefined class constant 'HEADER_CLIENT_IP'  


Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1

第 66 行的问题是 IlluminateHttpRequest::HEADER_CLIENT_IP => 'X_FORWARDED_FOR',.我在 stackoverflow 上搜索了其他帖子，但仍然没有运气.我尝试的最后一件事是在 composer dump 帖子中提到的 composer selfupdate 和 composer global update-自动加载无法识别的命令

The problem on line 66 is IlluminateHttpRequest::HEADER_CLIENT_IP => 'X_FORWARDED_FOR',. I have searched other posts on stackoverflow but still no luck. The last thing I tried was composer selfupdate and composer global update which was mentioned on the post composer dump-autoload not recognized command

另外，我不能删除 "minimum-stability": "dev","prefer-stable": true 因为如果我这样做，我会得到以下错误:

Also, I cannot remove "minimum-stability": "dev","prefer-stable": true because if I do, then I will get the following error:

    - Installation request for laravel/framework 5.6.* -> satisfiable by laravel/framework[5.6.x-dev].
- Removal request for laravel/framework == 5.6.9999999.9999999-dev

我分别附上了我的 composer.json 文件和 trustproxy.php.任何帮助将不胜感激.

I have attached my composer.json file and trustedproxy.php respectively. Any help will be highly appreciated.

推荐答案

我这样做了，而且效果很好.

I did this and it works perfectly.

1.composer.json:

来自:

"require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.5.*",
        "laravel/tinker": "~1.0"
    },

致:

"require": {
        "php": ">=7.1.3",
        "fideloper/proxy": "~4.0",
        "laravel/framework": "5.6.*",
        "laravel/tinker": "~1.0"
    },

2.将 appHttpMiddlewareTrustedProxies.php 文件替换为以下内容:

<?php

namespace AppHttpMiddleware;

use IlluminateHttpRequest;
use FideloperProxyTrustProxies as Middleware;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array
     */
    protected $proxies;

    /**
     * The headers that should be used to detect proxies.
     *
     * @var string
     */
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
}
