webman 聊天室demo（ctrl+c && ctrl+v）

凌晨三点半的卢本伟 更新于2022-12-18

这个是我自己的demo项目，用一个后台做前端页面，后续会加上一个博客功能，目前只做了首页跟聊天室，再根据现有的页面完善这个项目

http://wm.1967it.top/

1. 在webman基础上引入文件

composer require webman/gateway-worker

2. 开启7272端口

3. 开启前端路由

4.下载官方聊天室demo

https://www.workerman.net/doc/gateway-worker/

5.前端页面代码，复制静态文件放到webman的public目录下,

根据实际项目修改你当前项目的路径

头像的话自己加一张图片，这是我的路径

$("#dialog").append('<div class="speech_item"><img src="http://wm.1967it.top/public/chat/web/img/1.jpg" class="user_icon" height="42" width="50"/> '+from_client_name+' <br> '+time+'<div style="clear:both;"></div><p class="triangle-isosceles top">'+content+'</p> </div>').parseEmotion();

7.展示成品效果，跟官方的一毛一样，我这个只是研究webman的聊天功能，仅此而已。后续会自己做一个私聊模式
