Design & Implementation Notes

  • The problem
    • Scanning the QR code to login web wechat
    • No published official WeChat api interface
  • Workaround for login
    • Need login manually by scanning the QR code once
    • Capture all the required data as hubot configuration(details in next slide)
  • Shoot the trouble
    • Use chrome/firefox to analyze web WeChat API
    • Try its web APIs by curl
    • Analyze the parameters and what it is
    • Analyze the wxApp.js
  • Notes:
    • The hubot wechat on the mobile side keeps online is preferred
    • Reason: WeChat server disconnects your hubot with websync failure after 3~4 days. But hubot works again once login mobile wechat app again.
