How to develop seata-php? Brief analysis of development guide

How to develop seata-php? This article will talk about the seata-php development guide and explain some pre-requisite knowledge. I hope it will be helpful to you!

This article mainly hopes to help everyone participate in the development of seata/seata-php, and provide some explanations of pre-requisite knowledge .

seata/seata-php is currently a distributed transaction component package developed based on the hyperf framework and is compatible with swoole and swow Two coroutine extensions, I hope that subsequent developers can also consider compatibility with these two coroutine extensions

Pre-requisite knowledge

I hope that everyone must understand the following things before participating in seata/seata-php development

• seata

• ##hyperf development documentation

##swoole documentation
swow

##How to start the project

First We need to find a file directory to download the code

# 根据自己实际情况来创建目录
mkdir ./seata-dev

Next enter our directory

# 根据自己实际情况来创建目录
cd ./seata-dev

We will clone seata/seata-php

# 根据自己实际情况来创建目录
git clone git@github.com:seata/seata-php.git

Next Depending on whether you are using swoole or swow, execute the following commands to create a framework project, along with a hyperf project creation document hyperf

# swoole
composer create-project hyperf/hyperf-skeleton 

# swow
composer create-project hyperf/swow-skeleton

# 使用 swow 扩展建议使用 hyperf3.0 版本
composer create-project hyperf/swow-skeleton:dev-master

The next step is to enter the project and download the

clone

The

seata/seata-php

is loaded into the projectFirst we need to modify the composer.json file in the project and add the following content

{
    "require": {
        "hyperf/seata": "dev-master"
    },
    "repositories": {
        "seata": {
            "type": "path",
            "url": "../seata-php"
        }
    }
}

Finally, execute composer update -o in the directory and project directory.

And use the command php bin/hyperf.php vendor:publis hyperf/seata Publish the seata configuration file

Finally use php bin/hyperf.php start Start the project

Finally, interested friends can also learn more about hyperf Documents related to component package development

seata -When was php started?

Finally, let me explain to you how the seata/seata-php

project was started

We can take a look at the code link of Hyperf\Seata\Listener\InitListener

in the

seata/seata-php

project:InitListener<pre class="brush:php;toolbar:false">&lt;?php declare(strict_types=1); /** * This file is part of Hyperf. * * @link https://www.hyperf.io * @document https://hyperf.wiki * @contact group@hyperf.io * @license https://github.com/hyperf/hyperf/blob/master/LIC */ namespace Hyperf\Seata\Listener; use Hyperf\DbConnection\Db; use Hyperf\Event\Contract\ListenerInterface; use Hyperf\Framework\Event\MainWorkerStart; use Hyperf\Seata\Annotation\GlobalTransactionScanner; use Hyperf\Seata\Rm\DataSource\DataSourceProxy; use Hyperf\Server\Event\MainCoroutineServerStart; class InitListener implements ListenerInterface { protected GlobalTransactionScanner $globalTransactionScanner; protected DataSourceProxy $dataSourceProxy; public function __construct(GlobalTransactionScanner $globalTransactionScanner, DataSourceProxy $dataSourceProxy) { $this-&gt;globalTransactionScanner = $globalTransactionScanner;         $this-&gt;dataSourceProxy = $dataSourceProxy;     }     public function listen(): array     {         // 我们这里监听了下面两个事件,在 server 启动时候，则开始执行该监听器         return [             MainCoroutineServerStart::class,             MainWorkerStart::class,         ];     }     public function process(object $event)     {         // Execute any sql to init the database connection         Db::select('select 1');         // Init TM and RM clients         // 这里则是开始初始化 TM 和 RM 的客户端         $this-&gt;globalTransactionScanner-&gt;initClients();     } }</pre>At the end Let’s take a look at the life cycle document of hyperf
