lavarel 5.5升级到lavarel 5.6

一、修改composer.json文件夹前提php最低7.13

图中 "php": ">=7.1.3",
"fideloper/proxy": "~4.0",
"laravel/framework": "5.6.*",
"phpunit/phpunit": "~7.0",
修改完成后

二、清空缓存

php artisan view:clear
php artisan route:clear

三、composer 更新

composer update

然后会有个坑处，会报错，需要修改点东西，打开界面报错

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;
