Python 2.7 upload error
Hi,
This was working up until a few weeks ago and I can't for the life of me see what is wrong - maybe a fresh set of eyes will help.
I am trying to loop through the contents of a directory and upload the unique files to an applicaiton folder in dropbox apps:
import dropbox
import os
from datetime import datetime
access_token = '########################'
def upload_file(file_from, file_to):
print "Source :"+file_from
print "Dest :"+file_to
dbx = dropbox.Dropbox(access_token)
f = open(file_from, 'rb')
dbx.files_upload(f.read(), file_to)
for jpgfile in os.listdir("/home/pi/pir/captures/jpg"):
if jpgfile.endswith(".jpg"):
print datetime.now().strftime("%y/%m/%d %H:%M:%S")+": "+"Uploading capture image."#
file_from='/home/pi/pir/captures/jpg/180817182433.jpg'
file_to = '/PIR_APP/180817182433.jpg
upload_file(file_from, file_to)Note, I have hardcoded the file name for testing purposes.
I get the following error:
Traceback (most recent call last):

Any ideas?
Thanks in advance,

It looks like this is failing at a much lower level than the Dropbox SDK, so I'm afraid I can't offer too much insight. For reference, here's the documentation for the 'OpenSSL.SSL.WantWriteError' error.
Your Dropbox code looks fine though, and I just tried it and it worked for me (when putting in a valid path on my computer).
A few thoughts to try to narrow this down:
- Is there anything on the network connection, e.g., firewall, proxy, etc., that may be interfering with the Dropbox API HTTPS connection (to content.dropboxapi.com in particular, for uploads)?
- Does this happen only for specific file(s), or any files?
- Does downloading work?
- Does getting metadata work (e.g., files_list_folder or files_get_metadata)?
- Did you change/update any libraries when this broke?
- Have you tried this on another computer, and if so does this issue reproduce elsewhere?
A bit more testing...
I fi I cange the file type filter to ".py" and remove the hardcoded filenames it works and the files get uploaded. So the DropBox API doesn't work with JPG files anymore????
I may have done an update (sudo get-apt update) recently, I can't remember.
Thanks for the link but I'm going to try the following as a workaround:

- Greg-DBThe Dropbox API certainly still works with .jpg files. (I tested your code with a .jpg file in fact.)
At the layer where this is failing, the file type shouldn't matter anyway. It may have to do with the file size though. Perhaps try to different sizes to verify that?
Otherwise, it if you did do an update, it may be a bug in one of those lower level libraries.
