篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了微信小程序实现即时通信聊天功能的实例代码相关的知识,希望对你有一定的参考价值。
项目背景:小程序中实现实时聊天功能
一、服务器域名配置
配置流程
配置参考URL:https://developers.weixin.qq.com/miniprogram/dev/api/api-network.html
二、nginx中配置反向代理加密websocket(wss)

三、安装swoole
编译安装:

wget http: //pecl.php.net/get/swoole-1.9.3.tgz //下载swoole tar -zvxf swoole-1.9.3.tgz //解压swoole cd swoole-1.9.3/; //进入swoole /usr/local/php54/bin/phpize; //生成configure ./configure -- with -php-config=/usr/local/php/bin/php-config make && make install //安装 cd /phpstudy/server/php/lib/php/extensions/no-debug-non-zts-20121212 //查看是否安转上了swoole.so (注意:此文件下边都是你安装的拓展) vim /phpstudy/server/php/etc/php.ini //在php.ini添加extension=swoole.so加入到文件最后一行 lnmp restart; //重启nginx php -m; //查看phpinfo,这时候swoole拓展已经装上了 |
四、服务器端运行程序
1、创建server.php放到项目的根目录即可

<?php //实例化一个swoole的websocket服务监听本机的9501端口 $server = new swoole_websocket_server( "服务器IP" , 9090); //只需要绑定要监听的ip和端口。如果ip指定为127.0.0.1,则表示客户端只能位于本机才能连接,其他计算机无法连接。 //端口这里指定为9090,可以通过netstat查看下该端口是否被占用。如果该端口被占用,可更改为其他端口,如9502,9503等。 $server->on( \'open\' , function (swoole_websocket_server $server, $request) { echo "你好连接成功{$request->fd}\\n" ; }); $server->on( \'message\' , function (swoole_websocket_server $server, $frame) { foreach($server->connections as $key => $fd) { $user_message = $frame->data; $server->push($fd, $user_message); } }); $server->on( \'close\' , function ($ser, $fd) { echo "client {$fd} closed\\n" ; }); $server->start(); ?> |
2、由于swoole_server只能运行在CLI模式下,所以不要试图通过浏览器进行访问,这样是无效的,我们在命令行下面执行,注意一定要找到php的绝对路径php server.php (这行代码的意思是,把程序在服务器跑起来)
注意:php server.php
命令运行后,下面的黑框关闭后将无法聊天。所以一般使用命令:nohup php server.php &
五、客户端
