You have to ask the backend about this...

• First confirm whether there is any problem with the agreed interface. Did you call it according to the URL, method and parameters of the agreed interface?

• Confirm that it is not a permission issue

• Ask the backend. If the upload is successful but the file cannot be retrieved, let the backend give you an example of how to retrieve the file. You can try it

Check whether it is really transmitted to the server. If it is on the server, the path is wrong.

Log in to the server and check where it is, the file name, path, etc. Then check the consistency of your access address
I just saw the long-distance transfer pictures of our game today, the file names, unified naming rules before and after, the directory must be writable;
To ensure security, the backend will first move to tmp and then rename the new address
