Python SDK File Uploading - Working with the Response
Hi there,
I am new to interfacing with the Dropbox API and am using Python 3.6
I am uploading large files to my account using the following function called dropboxupload (not my own) . I simply call it at the end of my code:
import os import sys from tqdm import tqdm import dropbox filenameonly = sys.argv[1] filenamewithextension = sys.argv[2] fullfilepath = sys.argv[3] access_token = "removedforsecurity" def dropboxupload(access_token,file_path,target_path,timeout=3600,chunk_size=150 * 1024 * 1024,): dbx = dropbox.Dropbox(access_token, timeout=timeout) with open(file_path, "rb") as f: file_size = os.path.getsize(file_path) chunk_size = 150 * 1024 * 1024 if file_size <= chunk_size: print(dbx.files_upload(f.read(), target_path)) else: with tqdm(total=file_size, desc="Uploaded") as pbar: upload_session_start_result = dbx.files_upload_session_start( f.read(chunk_size) ) pbar.update(chunk_size) cursor = dropbox.files.UploadSessionCursor( session_id=upload_session_start_result.session_id, offset=f.tell(), ) commit = dropbox.files.CommitInfo(path=target_path) while f.tell() < file_size: if (file_size - f.tell()) <= chunk_size: print( dbx.files_upload_session_finish( f.read(chunk_size), cursor, commit ) ) else: dbx.files_upload_session_append( f.read(chunk_size), cursor.session_id, cursor.offset, ) cursor.offset = f.tell() pbar.update(chunk_size) dropboxupload(access_token, fullfilepath, "/"+filenamewithextension)
It works perfectly.
The response that comes back automatically is the FileMetadata; example as follows:
FileMetadata(name='500.mp4', id='id:a5yk0DAylOAAAAAAAAADbA', client_modified=datetime.datetime(2020, 2, 19, 13, 56, 31), server_modified=datetime.datetime(2020, 2, 19, 13, 56, 31), rev='59eee27d89b134c0970a9', size=512727070, path_lower='/500.mp4', path_display='/500.mp4', parent_shared_folder_id=None, media_info=None, symlink_info=None, sharing_info=None, is_downloadable=True, export_info=None, property_groups=None, has_explicit_shared_members=None, content_hash='e134be9c61057696145fbe4c416d5e62c983649bb756c9e9597d982781a1cb83')
What i want to do is capture this response and use the data within it for other means in the next step of my project.
For example i want to take the id and set as a new variable called "data". I have tried doing this with
data = str(dropbox.files.FileMetadata.id) print ("THE DATA VARIABLE IS") print(data)
but all that gets printed is....
THE DATA VARIABLE IS property object at 0x03A82F60
I am obviously capturing the data wrong - please can you help?!
Thanks

Hi yekootmada,
Your code will work when you refer to actual metadata! Where in the code you get the uploaded file's metadata?! :thinking: Only in the function you use! :wink: This function don't return anything yet. Just return the metadata as a result (small modification) and use it further after.
Out of your question: That function has a hidden BUG!!! Be careful! Even not very likely, it's possible the size of a big file to be exactly equal to multiple of the chunk size. In such a case transmission will never be finalized! No check in the algorithm for such a situation and finalization left not guaranteed.
Hope this gives a direction.

Thank you!
That is the part I am struggling with! I cannot find the correct syntax to return the response as data.
I tried
data = dropbox.files.FileMetadata.id print("THE DATA VARIABLE IS") print(data)
but the result is
THE DATA VARIABLE IS property object at 0x03A82F60

If you are newbie, learn some basics of Python syntax, at least. On your question: there is keyword 'return', as in many other languages (like C/C++, Java, Kotlin and others), which denote the returning value. This keyword could be used more than once, whenever the algorithm have a value ready to return. When such function gets called it carries a returned value which could be used directly or assigned to a variable. Follows some pseudo code:
def funcName(param1, param2): ...do some calculations... if some.check(): return param1+param2 ...do something else... result = param1 * param2 ...possible finalization... return result resValue = funcName(3, 5) ...do something using resValue here...
Hope this casts some extra light.

The 'dropbox.files.FileMetadata' is just the class, and not an instance containing the information for this uploaded file. That is, you'll want to do something like this (or return it and use it later like Здравко said):
file_metadata = dbx.files_upload_session_finish(f.read(CHUNK_SIZE), cursor, commit) print("This is the id of the uploaded file:") print(file_metadata.id)

great thanks Greg.
Still cant find where that should go in, everytime I try its giving me inconsistent use of tabs, spaces and indentations error.
