在laravel5.8中集成swoole组件----用协程实现的服务端和客户端(nginx配置篇章)

• laravel项目中的配置  原文出处：https://laravelacademy.org/post/19700.html，感谢原文作者让laravel这款可爱的php框架，进入了高并发的殿堂

如果你已经成功安装了laravelS组件，并用他接管了你的laravel项目，那么接下来就是实现一个websocket服务器的类，
类声明在项目app目录下的Services（没有就自己建一个）目录，
也许这些命名空间已经多的把你吓了一跳，但其实他们都源自你安装的laravelS组件，类的实现部分你也许并不感到陌生，没错，
他们就是按照swoole websocket原生类进行了封装

Hhxsv5类空间的源码可以参照 项目空间下的vendor/hhxsv5/laravel-s/src/Swoole/Coroutine

<?php
namespace App\Services;

use Hhxsv5\LaravelS\Swoole\WebSocketHandlerInterface;
use Illuminate\Support\Facades\Log;
use Swoole\Http\Request;
use Swoole\WebSocket\Frame;
use Swoole\WebSocket\Server;
class mywebsocket implements WebSocketHandlerInterface
{

    public function __construct()
    {
        Log::info('launching laravel-swoole websocket');
    }

    public function onOpen(Server $server, Request $request)
    {
        Log::info('launching swoole websocket');
        $server->push($request->fd,'欢迎使用，基于swoole的laravel websocket');
    }

    public function onMessage(Server $server, Frame $frame)
    {
        $server->push($frame->fd,date('Y-m-dH:i:s').'服务器响应你的请求');
    }

    public function onClose(Server $server, $fd, $reactorId)
    {
        Log::info('websocket服务器关闭');
    }
}

然后，你就要到config目录下找到laravels.php,进行一番配置。

找到下列关联数组的键名，并作配置

'websocket'                => [
        'enable' => true,
        'handler'=>\App\Services\mywebsocket::class,#这个就是上述声明的类
        //'handler' => XxxWebSocketHandler::class,
    ],

'swoole' => [
    ...

    // 每隔 60s 检测一次所有连接，如果某个连接在 600s 内都没有发送任何数据，则关闭该连接
    'heartbeat_idle_time'      => ,
    'heartbeat_check_interval' => ,

    ...
],

• nginx配置部分(分站点配置)

如果你对nginx多站点配置还感到陌生，可以随便搜罗一篇博文来看，这里的配置是在分站点目录vhosts下的，针对目标站点的 
.conf文件进行配置的，如果你急于上机，不妨全部拷贝，把域名更改过来

map $http_upgrade $connection_upgrade #这行代码的目的是把http协议 “提升”到websocket协议的标准
{
    default upgrade;
    ''      close;
}
upstream laravels {#server后面是需要监听的ip地址，如果你使用了docker容器部署你的项目，那server后面跟的是容器名
    # Connect IP:Port
    server yinti.com: weight= max_fails= fail_timeout=30s;
    keepalive ;
}

server {
    listen       ;#端口可以根据项目实际需要进行调整
    server_name yinti.com;
    root  /dingshub2/yinti/public;
    index index.html index.htm index.php;

    location / {
        # WordPress固定链接URL重写
        try_files $uri @laravels;

    }

    # PHP配置
    location ~ \.php$ {
            fastcgi_pass   127.0.0.1:;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
    }
    #下面这段是websocket服务器的具体部署实现
    location =/ws {
        # proxy_connect_timeout 60s;
        # proxy_send_timeout 60s;
        # proxy_read_timeout: Nginx will close the connection if
 the proxied server does not send data to Nginx in  seconds;
        # At the same time, this close behavior is also affected by heartbeat setting of Swoole.

        proxy_set_header X-Real-IP $remote_addr;

• html实现部分(blade模版，继承了母版页)

@extends('masterpage.chatroom')

@section('passage')
    <div class="pricing-header px-3 py-3 pt-md-5 pb-md-4 mx-auto text-center">
        <h1 class="display-4">帅哥聊天室</h1>
        <p class="lead">四海之内皆兄弟，请文明交流</p>
    </div>
@endsection

@section('pad')
    <div class="card-deck mb-3">
        <div class="card mb-10 box-shadow">
            <div class="card-header">
                <h4 class="my-0 font-weight-normal  text-center">交流板</h4>
            </div>
            <div class="card-body">
                <h1 class="card-title pricing-card-title"> <small class="text-muted"></small></h1>
                <textarea id="chatpad" class='form-control' cols="" rows=""></textarea>
                <p style="margin-left: 2px" class="my-0 font-weight-normal">消息输入框</p>
                <textarea class='form-control'  cols="" rows=""></textarea>
                <br>
                <button id="joinin" type="button" class="btn btn-lg btn-block btn-outline-primary">进入聊天室</button>
            </div>
        </div>
    </div>
@endsection

@section('tailscript')
    <script src="{{asset(config('mystatic._js_').'/jquery-3.3.1.min.js')}}" ></script>
    <script src="{{asset(config('mystatic._myjs_').'/joinintalk.js')}}"></script>
@endsection

• js具体实现----点击按钮即实现websocket服务器的连接

$("#joinin").click(function()
{
    var mysocket = new WebSocket('ws://yinti.com:5200/ws');
    mysocket.onopen=function (event) {
        $("#chatpad").val("");
        $("#chatpad").val("大家好！音提来了\n");
    };

});
