# WebSocket development skeleton
帮助你快速搭建 WebSocket 项目骨架,并指导你如何使用该骨架的细节,骨架默认开启了 SQL、Redis 日志,压测前请先关闭 `.env` 的 `APP_DEBUG`
## 安装
> 需要先安装 [Swoole](https://wiki.swoole.com/#/environment)
- Swoole >= 4.4.15: https://wiki.swoole.com/#/environment
```
composer create-project --prefer-dist mix/websocket-skeleton websocket
```
## 快速开始
启动 Swoole 协程服务
```
composer run-script --timeout=0 swooleco:start
```
## 执行脚本
- `composer run-script` 命令中的 `--timeout=0` 参数是防止 composer [执行超时](https://getcomposer.org/doc/06-config.md#process-timeout)
- `composer.json` 定义了命令执行脚本,对应上面的执行命令
```json
"scripts": {
"swooleco:start": "php bin/swooleco.php",
"cli:clearcache": "php bin/cli.php clearcache"
}
```
当然也可以直接下面这样启动,效果是一样的,但是 `scripts` 能帮你记录到底有哪些可用的命令,同时在IDE中调试更加方便。
```
php bin/swooleco.php start
```
## 编写一个 WebSocket 服务
首先修改根目录 `.env` 文件的数据库信息
然后在 `routes/index.php` 定义一个新的路由
```php
$vega->handle('/websocket', [new WebSocket(), 'index'])->methods('GET');
```
路由里使用了 `WebSocket` 控制器,我们需要创建他
- 如何配置路由:[mix/vega](https://github.com/mix-php/vega#readme)
- 如何使用 WebSocket 升级器:[mix/websocket](https://github.com/mix-php/websocket#readme)
```php
upgrade($ctx->request, $ctx->response);
$session = new Session($conn);
$session->start();
}
}
```
控制器中使用了一个 `Session` 类来处理连接事务
```php
conn = $conn;
$this->writeChan = new Channel(10);
}
/**
* @param string $data
*/
public function send(string $data): void
{
$this->writeChan->push($data);
}
public function start(): void
{
// 接收消息
go(function () {
while (true) {
$frame = $this->conn->recv();
$message = $frame->data;
(new Hello($this))->index($message);
}
});
// 发送消息
go(function () {
while (true) {
$data = $this->writeChan->pop();
if (!$data) {
return;
}
$frame = new \Swoole\WebSocket\Frame();
$frame->data = $data;
$frame->opcode = WEBSOCKET_OPCODE_TEXT; // or WEBSOCKET_OPCODE_BINARY
$this->conn->send($frame);
}
});
}
}
```
在接收消息处,使用了 `src/Handler/Hello.php` 处理器对当前发送的消息做逻辑处理,我们只需根据自己的需求增加新的处理器来处理不同消息即可。
```
(new Hello($this))->index($message);
```
重新启动服务器后方可测试新开发的接口
> 实际开发中使用 PhpStorm 的 Run 功能,只需要点击一下重启按钮即可
```
// 查找进程 PID
ps -ef | grep swooleco
// 通过 PID 停止进程
kill PID
// 重新启动进程
composer run-script swooleco:start
```
使用测试工具测试
- [WEBSOCKET 在线测试工具](http://www.easyswoole.com/wstool.html) `ws://127.0.0.1:9502/websocket`
## 如何使用 WebSocket 客户端
- [mix/websocket#客户端-client](https://github.com/mix-php/websocket#%E5%AE%A2%E6%88%B7%E7%AB%AF-client)
## 使用容器中的对象
容器采用了一个简单的单例模式,你可以修改为更加适合自己的方式。
- 数据库:[mix/database](https://github.com/mix-php/database#readme)
```
DB::instance()
```
- Redis:[mix/redis](https://github.com/mix-php/redis#readme)
```
RDS::instance()
```
- 日志:[monolog/monolog](https://seldaek.github.io/monolog/doc/01-usage.html)
```
Logger::instance()
```
- 配置:[hassankhan/config](https://github.com/hassankhan/config#getting-values)
```
Config::instance()
```
## 部署
线上部署启动时,修改 `shell/server.sh` 脚本中的绝对路径和参数
```
php=/usr/local/bin/php
file=/project/bin/swooleco.php
cmd=start
numprocs=1
```
启动管理
```
sh shell/server.sh start
sh shell/server.sh stop
sh shell/server.sh restart
```
使用 `nginx` 或者 `SLB` 代理到服务器端口即可
```
location /websocket {
proxy_pass http://127.0.0.1:9502;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
```
