In this project, we exposed some useful back-end helper APIs:

1. captureHTMLScreen

   This service uses headless browser to capture any HTML page to a image file and store it into Qiniu cloud

2. drawQRCodeOnPicture

   This api can draw a QR code on a picture in any position you want

3. copyRemoteFile

   Copy any remote file to Qiniu cloud

4. recognize

   Convert Wechat's audio file from silk format to wav format so most voice engine can process

   More apis will come...

   How to use it???

   Very simple, just build a docker image by using the Dockerfile, and deploy it.
