# 微信公众号channel

鉴于个人微信号在服务器上通过itchat登录有封号风险,这里新增了微信公众号channel,提供无风险的服务。
目前支持订阅号和服务号两种类型的公众号。个人主体的微信订阅号由于无法通过微信认证,接口存在限制,目前仅支持最基本的文本交互和语音输入。通过微信认证的订阅号或者服务号可以回复图片和语音

程序启动并监听端口后,在刚才的“服务器配置”中点击`提交`即可验证你的服务器。
随后在[微信公众平台](https://mp.weixin.qq.com)启用服务器,关闭手动填写规则的自动回复,即可实现ChatGPT的自动回复。

如果在启用后如果遇到如下报错:
之后需要在公众号开发信息下将本机IP加入到IP白名单。

不然在启用后,发送语音、图片等消息可能会遇到如下报错:
```
'errcode': 40164, 'errmsg': 'invalid ip xx.xx.xx.xx not in whitelist rid
```

需要在公众号开发信息下将IP加入到IP白名单。

## 个人微信公众号的限制
由于人微信公众号不能通过微信认证,所以没有客服接口,因此公众号无法主动发出消息,只能被动回复。而微信官方对被动回复有5秒的时间限制,最多重试2次,因此最多只有15秒的自动回复时间窗口。因此如果问题比较复杂或者我们的服务器比较忙,ChatGPT的回答就没办法及时回复给用户。为了解决这个问题,这里做了回答缓存,它需要你在回复超时后,再次主动发送任意文字(例如1)来尝试拿到回答缓存。为了优化使用体验,目前设置了两分钟(120秒)的timeout,用户在至多两分钟后即可得到查询到回复或者错误原因。
