implement file upload on Android phone, upload and read address is C:.paked (forget how to write)
use API for createUpload upload can upload server, but file can"t be downloaded always think it is a problem to get file path, I would like to ask how to get the file address and how to splice the address
since it can be uploaded to the server, did the server receive your request to process and save the image and return a correct url?
if the server processes successfully, it will return a url, that url is the address where the image is downloaded
1. The client requests the backend interface to upload the file
2, and the backend interface will handle the file storage operation, including the specific storage address
3, call the backend to return to you
4 directly, or write the backend
