Reasons for not sending requests after uni app packaging

Developing uni-app There are always various strange things when bug, Take the request interface for example , Real machine debugging and wechat developer tools can send requests normally , Pack it up apk Then it failed , Why? ？

After some tumbling , I found that both real machine debugging and wechat developer tools are development environments , Pack it up apk Then there is the production environment , Finally, modify the production environment baseUrl that will do .

encapsulation request It is much more convenient in development , But it is easy to cause some bug.
