Recently, silly loser app wechat authorized login reported an error 40029. After checking for a long time, I finally found that the appid configured by the back-end code is different from that configured by the app. If this error occurs, on the one hand, check whether the code is used and whether the configuration file is the same

{” errcode”:40029,”errmsg”:”invalid code, hints: [ req_id: bHlBdZyFe-tOmSea ]”}
