• 2.1 版本主要增加了底层驱动 hyperf/engine，允许 Hyperf 框架跑在 Swoole 或 Swow 之上。
• PHP 最低版本由 7.2 修改为 7.3

Swow 暂为预览版本，请谨慎使用。

修改 Hyperf 组件版本

直接将 composer.json 中的 hyperf/* 统一修改为 2.1.* 即可。

{
    "require": {
        "php": ">=7.3",
        "ext-json": "*",
        "ext-openssl": "*",
        "ext-pdo": "*",
        "ext-pdo_mysql": "*",
        "ext-redis": "*",
        "ext-swoole": ">=4.5",
        "hyperf/async-queue": "2.1.*",
        "hyperf/cache": "2.1.*",
        "hyperf/command": "2.1.*",
        "hyperf/config": "2.1.*",
        "hyperf/constants": "2.1.*",
        "hyperf/contract": "2.1.*",
        "hyperf/database": "2.1.*",
        "hyperf/db-connection": "2.1.*",
        "hyperf/di": "2.1.*",
        "hyperf/dispatcher": "2.1.*",
        "hyperf/event": "2.1.*",
        "hyperf/exception-handler": "2.1.*",
        "hyperf/framework": "2.1.*",
        "hyperf/guzzle": "2.1.*",
        "hyperf/http-server": "2.1.*",
        "hyperf/logger": "2.1.*",
        "hyperf/model-cache": "2.1.*",
        "hyperf/pool": "2.1.*",
        "hyperf/process": "2.1.*",
        "hyperf/redis": "2.1.*",
        "hyperf/server": "2.1.*",
        "hyperf/utils": "2.1.*"
    },
    "require-dev": {
        "friendsofphp/php-cs-fixer": "^2.14",
        "hyperf/devtool": "2.1.*",
        "hyperf/testing": "2.1.*",
        "mockery/mockery": "^1.0",
        "phpstan/phpstan": "^0.12.18",
        "swoole/ide-helper": "dev-master",
        "symfony/var-dumper": "^5.1"
    }
}

后面只需要执行 composer update -o，就可以正常完成升级了。

增加 optimize-autoloader 配置

因为 Hyperf 自从 2.0 开始，需要使用到 composer 生成的 class_map，这就要求用户每次更新依赖都要使用 -o 进行优化，但很多用户从来没有这个习惯。 于是我们建议在 composer.json 中增加对应配置，以满足这个需要。

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

修改 SwooleEvent

类 Hyperf\Server\SwooleEvent 在 2.1 中已经更名为 Hyperf\Server\Event，所以我们需要在 server.php 配置中修改对应代码。

SwooleEvent 会在 3.0 中正式被移除，请尽快修改为 Event

<?php

declare(strict_types=1);

use Hyperf\Server\Event;
use Hyperf\Server\Server;

return [
    'mode' => SWOOLE_BASE,
    'servers' => [
        [
            'name' => 'http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 9501,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
            ],
        ],
    ],
    'callbacks' => [
        Event::ON_BEFORE_START => [Hyperf\Framework\Bootstrap\ServerStartCallback::class, 'beforeStart'],
        Event::ON_WORKER_START => [Hyperf\Framework\Bootstrap\WorkerStartCallback::class, 'onWorkerStart'],
        Event::ON_PIPE_MESSAGE => [Hyperf\Framework\Bootstrap\PipeMessageCallback::class, 'onPipeMessage'],
        Event::ON_WORKER_EXIT => [Hyperf\Framework\Bootstrap\WorkerExitCallback::class, 'onWorkerExit'],
    ],
];

分页器

因为组件 hyperf/paginator 已从 hyperf/database 依赖中移除。所以在 database 中使用到分页器的同学，还需要额外引入 hyperf/paginator 组件。

修改 DBAL 版本

倘若使用了 doctrine/dbal 组件，则需要升级到 ^3.0 版本。

移除组件 doctrine/common

doctrine/common 组件与 hyperf/utils 存在依赖冲突。故需要从 composer.json 中移除此组件。

# 移除组件
composer remove doctrine/common
# 更新
composer update "hyperf/*" -o

注意事项

• 尽量不要将老项目的引擎修改为 Swow，如果想要使用 Swow，请尽量在新项目中尝试。因为 Swow 并不是 Swoole 的替代品，所以并不是所有 Swoole 的场景，都能在 Swow 中找到对应的替代方案。
