java - 微信菜单点击回复即使生成的图片？

Question

就是点击微信菜单栏自动给用户回复一张图片，但这张图片是临时生成的，每个用户都有自己的二维码！

Answer 1

If you want to reply to only one picture, you need to authenticate the public account permissions. First upload the picture to WeChat material and obtain the mediaid returned. Since the WeChat interface requires a response in 5 seconds, it may time out

It is recommended to use the customer service interface function to proactively send messages or only reply to the user with a picture URL
