I can no longer upload files

Hi all,

For some time now I have not been able to upload my files via the HTTP API.

The file/upload or file/get_temporary_upload_link gives me a 404 error even though it worked perfectly until now.

If I do CURL tests then everything works perfectly, so I suspect an unsupported header. Here is the list of headers on my HTTP request (I use python/requests to do this):

Headers: {'User-Agent': 'python-requests/2.25.1', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Content-Type': 'application/octet-stream', 'Dropbox-API-Arg': '{"mode":"overwrite","path":"/Sans nom 1.odt","autorename":false,"mute":false,"strict_conflict":false}', 'Content-Length': '473722', 'Authorization': 'Bearer sl.B_3Hk1dv...'}

I'll try adding these headers to CURL to see if that's where it comes from, but I'm interested in any good information.

Thanks.

Ok the CURL header that seems to be no longer supported is:

--header "Accept-Encoding: gzip, deflate" \

How is this possible?

I just gave this a try myself, but I'm not getting back a 404 error when I use that header. Can you share the full request and response for this issue so we can take a look? If you're using curl, use the -v option to enable verbose mode. Please redact your access token though. Thanks in advance!

Hi Greg,

No, it doesn't come from the headers, sorry.

I can get this Curl query to work correctly:

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer sl.B_2..." \
    --header "Dropbox-API-Arg: {\"autorename\":false,\"mode\":\"overwrite\",\"mute\":false,\"path\":\"/Test Dropbox.odt\",\"strict_conflict\":false}" \
    --header "User-Agent: python-requests/2.25.1" \
    --header "Accept-Encoding: gzip, deflate" \
    --header "Accept: */*" \
    --header "Connection: keep-alive" \
    --header "Content-Type: application/octet-stream" \
    --write-out "%{http_code}\n" \
    --data-binary "@/home/prrvchr/Test Dropbox.odt"

On the other hand, if I use Python/Requests instead of Curl, it gives me a 404:

import requests

url = 'https://content.dropboxapi.com/2/files/upload'
headers = {'Content-Type': 'application/octet-stream',
           'Dropbox-API-Arg': '{"autorename": false, "mode": "overwrite", "mute": false, "path": "/Test Dropbox.odt", "strict_conflict": false}',
           'Authorization': 'Bearer sl.B_2...'}
data = open('/home/prrvchr/Test Dropbox.odt', 'rb')
response = requests.put(url, headers=headers, data=data)
print("Status Code: %s" % response.status_code)
response.close()
data.close()

I don't see why...

Thanks for following up and sharing that. In your Python code, you're using the "PUT" method, via the ".put" call, however the /2/files/upload endpoint expects a "POST". That would be ".post" in the requests library.

Thanks Greg for finding my mistakes...

But this code that you just corrected was only created to test the file/get_temporary_upload_link command which has stopped working for some time.

And I just found what was preventing it from working, it is apparently the temporary upload link which no longer supports an Authorization headers which was there by mistake.

Here is an example of code that worked and no longer works, it now returns a status code 500:

import requests

url = 'https://api.dropboxapi.com/2/files/get_temporary_upload_link'
token = 'Bearer sl.B_...'
headers = {'Authorization': token}
json = {'commit_info': {'path': '/Test Dropbox.odt',
                        'mode': 'overwrite'},
        'duration': 3600}
response = requests.post(url, headers=headers, json=json)
if not response.ok:
    print("Request on Url: %s give Status Code: %s" % (url, response.status_code))
    response.close()
else:
    url = response.json().get('link')
    response.close()
    headers = {'Content-Type': 'application/octet-stream',
               'Authorization': token}
    data = open('/home/prrvchr/Test Dropbox.odt', 'rb')
    response = requests.post(url, headers=headers, data=data)
    print("Request on Url: %s give Status Code: %s" % (url, response.status_code))
    response.close()
    data.close()

Anyway, all these problems were caused by a mistake in my code and now it is fixed.

Thanks for your help and I think we can close.
