It is best to modify the Avatar url after the avatar changes.

If you want the url to remain unchanged, remember to include? R = xxxRemember thisXxxRandomly generated by the server or client each time.

Another method is to use a fixed url for a user's profile picture, such as facebook. However, when accessing this url, a 302 jump will be generated to the real image address, the actual image address ensures that each avatar is different.
