Deploy WeChat Official Account Bot ​

Deploy WeChat Official Account bot to connect with LangBot.

LangBot WeChat Official Account Integration Modes ​

Currently, LangBot provides two ways to integrate with WeChat Official Accounts:

  1. Traditional Message Exchange Mode

    • Official accounts require requests to be processed within 15 seconds, AI-generated content that exceeds this timeout cannot be sent.
    • When AI content generation timeout occurs, LangBot will print request timeout information in the console.

  2. "Send Any Text to Get Reply" Mode

    • This method can break the 15 second limit, but very long text may not be sent successfully.
    • When using this method, after sending a message to the official account, it will reply "AI is thinking, please send any content to get the answer". At this point, you need to send any content to get the answer.

For more complex functionality, please contact the LangBot team for customized support.

Create Bot ​

Enter the WeChat Official Account Platform, if you already have an official account, scan the QR code to log in and enter the console. If you haven't registered an official account before, click Register Now, select Official Account, fill in the information in sequence, and enter the console. The console looks like this: Console Page

Set Callback Address ​

Get Configuration Items ​

Click Settings and Development, Development Interface Management, and you'll see a page like this: Set Development Items

Record the Developer ID (AppID), Developer Password (AppSecret), and add the server where LangBot is deployed to the IP Whitelist.

Set Up Reverse Proxy ​

Since WeChat Official Accounts only support http (port 80) and https (port 443), this article assumes that port 80 is already occupied and uses port 443 to reverse proxy to LangBot.

The specific reverse proxy configuration tutorial is the same as the QQ Official Bot Reverse Proxy Configuration, except that reverse_proxy 127.0.0.1:2284 is changed to reverse_proxy 127.0.0.1:2287.

Save Callback Address ​

Click Set Server Configuration, enter Token, EncodingAESKey, and change the message encryption/decryption method to Safe Mode.

At this point, open the LangBot Webui page, create a new bot, and fill in the four configuration items obtained (AppID, AppSecret, token, EncodingAESKey)

Set Development Items

In the configuration items, the Mode option is the selected integration mode, where the default is drop. drop is the traditional message exchange mode, and passive is the "send any text to get reply" mode.

The LoadingMessage option is the loading message, which can be changed to other content, and is only valid when the mode is passive. Set enable to true.

After filling in successfully, start LangBot.

Fill in the URL as https://your_domain_name/callback/command, where your_domain_name is the domain name filled in Caddy. Click Save. If it can be saved successfully, it means the deployment is successful. If you see System error, please try again later, please recheck whether the above configuration content is filled in correctly.
