I"ve been looking for it for a long time, but I can"t find it.

1. After the direct upload of web is completed, the server cannot know whether the file was uploaded successfully, who uploaded it, and the information of the file

2. Using web to directly call the server interface makes it feel much less reliable

3. It seems impossible to know the uploader information by using Tencent Cloud serverless cloud function scf, and sometimes it is not triggered. At present, bucket also has region restrictions
