need to transfer userid to openid
reference documentation: http://work.weixin.qq.com/api.

enter http://work.weixin.qq.com/api. into the browser to get openid, so ask this address in the project not to request the address in that silly document, and get the desired data.
I just want to say that the debug address " http://work.weixin.qq.com/api. is stable? Screw the documents and three unknown customer service!
