The binary content returned by the WeChat applet code interface is processed and returned to the front-end display

Insert picture description here

The code is as above. The name of the interface directly opened by the front end is the small program code returned by WeChat. Or the back-end can generate images and upload them to the image server, for example, to Alibaba Cloud OSS, and return an image address to the front-end. I didn't do this, and I feel a waste of resources. . .
