# 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（个人）和服务号（企业）两种类型的公众号，它们的主要区别就是被动回复和主动回复。
个人微信订阅号有许多接口限制，目前仅支持最基本的文本对话和语音输入，支持加载插件，支持私有api_key。
暂未实现图片输入输出、语音输出等交互形式。

```
然后运行`python3 app.py`启动web服务器。这里会默认监听8080端口，但是微信公众号的服务器配置只支持80/443端口，有两种方法来解决这个问题。第一个是推荐的方法，使用端口转发命令将80端口转发到8080端口（443同理，注意需要支持SSL，也就是https的访问，在`wechatmp_channel.py`需要修改相应的证书路径）：

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo iptables-save > /etc/iptables/rules.v4
```
第二个方法是让python程序直接监听80端口。这样可能会导致权限问题，在linux上需要使用`sudo`。然而这会导致后续缓存文件的权限问题，因此不是推荐的方法。
最后在刚才的“服务器配置”中点击`提交`即可验证你的服务器。
第二个方法是让python程序直接监听80端口，在配置文件中设置`"wechatmp_port": 80` ，在linux上需要使用`sudo python3 app.py`启动程序。然而这会导致一系列环境和权限问题，因此不是推荐的方法。

443端口同理，注意需要支持SSL，也就是https的访问，在`wechatmp_channel.py`中需要修改相应的证书路径。

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：
```
'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。

另外，由于微信官方的限制，自动回复有长度限制。因此这里将ChatGPT的回答拆分，分成每段600字回复（限制大约在700字）。

## 私有api_key
公共api有访问频率限制（免费账号每分钟最多20次ChatGPT的API调用），这在服务多人的时候会遇到问题。因此这里多加了一个设置私有api_key的功能。目前通过godcmd插件的命令来设置私有api_key。

## 语音输入
利用微信自带的语音识别功能，提供语音输入能力。需要在公众号管理页面的“设置与开发”->“接口权限”页面开启“接收语音识别结果”。

## 测试范围
目前在`RoboStyle`这个公众号上进行了测试（基于[wechatmp分支](https://github.com/JS00000/chatgpt-on-wechat/tree/wechatmp)），感兴趣的可以关注并体验。开启了godcmd, Banwords, role, dungeon, finish这五个插件，其他的插件还没有测试。百度的接口暂未测试。语音对话没有测试。图片直接以链接形式回复（没有临时素材上传接口的权限）。
## 语音回复
请在配置文件中添加以下词条：
```
"voice_reply_voice": true,
```
这样公众号将会用语音回复语音消息，实现语音对话。

默认的语音合成引擎是`google`，它是免费使用的。

如果要选择其他的语音合成引擎，请添加以下配置项：
```
"text_to_voice": "pytts"
```

pytts是本地的语音合成引擎。还支持baidu,azure，这些你需要自行配置相关的依赖和key。

如果使用pytts，在ubuntu上需要安装如下依赖：
```
sudo apt update
sudo apt install espeak
sudo apt install ffmpeg
python3 -m pip install pyttsx3
```
不是很建议开启pytts语音回复，因为它是离线本地计算，算的慢会拖垮服务器，且声音不好听。

## 图片回复
现在认证公众号和非认证公众号都可以实现的图片和语音回复。但是非认证公众号使用了永久素材接口，每天有1000次的调用上限（每个月有10次重置机会，程序中已设定遇到上限会自动重置），且永久素材库存也有上限。因此对于非认证公众号，我们会在回复图片或者语音消息后的10秒内从永久素材库存内删除该素材。

## 测试
目前在`RoboStyle`这个公众号上进行了测试（基于[wechatmp分支](https://github.com/JS00000/chatgpt-on-wechat/tree/wechatmp)），感兴趣的可以关注并体验。开启了godcmd, Banwords, role, dungeon, finish这五个插件，其他的插件还没有详尽测试。百度的接口暂未测试。[wechatmp-stable分支](https://github.com/JS00000/chatgpt-on-wechat/tree/wechatmp-stable)是较稳定的上个版本，但也缺少最新的功能支持。

## TODO
* 服务号交互完善
* 服务号使用临时素材接口，提供图片回复能力
* 插件测试
- [x] 语音输入
- [ ] 图片输入
- [x] 使用临时素材接口提供认证公众号的图片和语音回复
- [x] 使用永久素材接口提供未认证公众号的图片和语音回复
- [ ] 高并发支持
