Deleting .info files and moving uploaded file to another directory after upload complete

[kathirvelkg]

After successful upload, I need to move the uploaded file(.bin) to another directory and delete the .info file which is not need after that. Is there any call back function I can use to perform this operation.
And please let me know whether the following is feasible:
I have 'n' number of clients uploading files; I want to store the files in separate directory with respect to the client uploading it. This may be a feature of file server; but I foresee tus as a upload file server rather than just a uploading protocol.

If you use tusd programmatically using it's Go API, you can listen on the CompleteUploads channel in your handler struct (https://godoc.org/github.com/tus/tusd#UnroutedHandler). In the case that you are simply running the tusd binary, we currently have a hook system which allows you to run scripts whenever an upload is finished. However, this feature is not well documented yet, but you can try it:

tusd -hooks-dir ./hooks/

This will cause the ./hooks/post-finish file to be executed if an upload finishes. The process will have special environment variables (and can read from stdin) for more information about the upload (see https://github.com/tus/tusd/blob/master/cmd/tusd/main.go#L182).

I have 'n' number of clients uploading files; I want to store the files in separate directory with respect to the client uploading it.

I guess, the best way to implement this is to move the files after they have been uploaded and not in the beginning. You can use the hooks system for this as described above.

Thanks for the quick and detailed reply. hooks system will solve my problem and have gone through the hooks function.
I have developed the upload client using tus java client library; now the requirement is I should move the customer uploaded files under their directory; not to store all files in same directory. Is there any way I can share the customer guid to the server/ store it in the info.json; then I can use post finish hook to move the file to respective directory.

You can use the TusUpload#setMetadata method to add optional information to an upload:

TusUpload upload = new TusUpload(/* ... */);
Map<String, String> meta = upload.getMetadata();
meta.put("client_id", "55");
upload.setMetadata(meta);

This will then show up in the .info file in the MetaData object.

Thanks for the update. Hope this solves my problem. Will check and update

The following code
Map<String, String> meta = upload.getMetadata();
always returns null and adding new <k,v> pair throws null pointer exception.
I followed the same code which you have mentioned, since it returned null; I used
Map<String, String> meta = new HashMap<String, String>(); and it worked.

That's correct. It's not guaranteed that the object returned is not null. I will make sure to update the documentation to fix this.
