I am implementing WeChat SSO for my web application, I have developer account, created an application there, followed this article exactly. I am using React on front-end and flask on backend. I am using this package for flask for WeChat-sso. So in my weChat dashboard I have registered official website e.g (chess.com), but I have to use callback url in such way so I can test redirection on my dev server.
My dev front-end is on (localhost:8000/) My backend server is running on (127.0.0.1:5050/)
I have tried saving different callback urls e.g (127.0.0.1:5050/api/users/wechat/callback), no matter what I save in callback url always receiving parameter error.
So my question is how do I actually achieve this functionality locally? Instead of parameter error I should be seeing QR code so that I can get code from which I can get access_token. Following code generates authentication url
from weixin import WXAPPAPI
from weixin.lib.wxcrypt import WXBizDataCrypt
from weixin.client import WeixinAPI
scope = ("snsapi_login",)
api = WeixinAPI(appid=WECHAT_APP_ID,
app_secret=WECHAT_APP_SECRET,
redirect_uri=WECHAT_REDIRECT_URI)
authorize_url = api.get_authorize_url(scope=scope)
The authentication url generated is as follows, redirect URI is properly encoded just like in the documentation.
https://open.weixin.qq.com/connect/qrconnect?appid=wx35c78a124e8f027b&redirect_uri=127.0.0.1%3A5050%2Fapi%2Fusers%2Fwechat%2Fcallback&response_type=code&scope=snsapi_base&state=689db1f29605481a492639e98c7b1f9f#wechat_redirect
Please look at the picture of error as well thanks
