my ueditor image access prefix can"t be added!

set
"imageUrlPrefix": "http://127.0.0.1:8000", / picture access path prefix /

description:
1, background configuration and other codes are all intact
2, xadmin can display the picture correctly,
3, the path of the relevant picture saved in the database is the relative path
4, after setting imageUrlPrefix according to the Internet, the access path of the front end should be imageUrlPrefix plus the relative path, but the front end still shows the relative path, so the front end can not get the picture data

how can I set the access path of the front end to imageUrlPrefix plus the relative path
