最近在公司利用直播间搭建一个图文直播间时正好要用到chatsever，研究了一下html5的websocket 实现了双向通信，根据前人的经验折腾了几天弄了个聊天室，实现了发送图片，发送QQ表情，群聊私聊等功能，特地分享给各位新手参考学习，大牛可以忽略。

前端：client.html

P70系列延期，华为新旗舰将在下月发布

3月20日消息，近期博主@数码闲聊站透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。

而博主@定焦数码爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？
根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
