Error on put_file (Header)

[Atheryl]

Hi,

The library sounds amazing but I'm stuck with an issue while trying to upload something (Both put_file and put_directory)

requests.exceptions.InvalidHeader: Header value 1475201477.79 must be of type str or bytes, not <type 'float'>

The full stack :

Traceback (most recent call last):

Running on Centos 7, python 2.7

Can you tell me the exact file size in bytes of file-2016-08.xlsx ? Could be related to #175

[Atheryl]

It's a pretty small file below 50 KB.

I can try the fix about Thursday to confirm.

[PVince81]

hmm, but the header says 1475201477.79 which sounds like 1 TB, weird

[Atheryl]

I think that's a timestamp

Timestamp Converter
1475201477.79
Is equivalent to:

09/30/2016 @ 2:11am (UTC)
2016-09-30T02:11:17+00:00 in ISO 8601

Fri, 30 Sep 2016 02:11:17 +0000 in RFC 822, 1036, 1123, 2822

Friday, 30-Sep-16 02:11:17 UTC in RFC 2822

2016-09-30T02:11:17+00:00 in RFC 3339

Ah, indeed. I guess it might be the OC-MTime header.

So the code needs to be fixed to remove the decimal places I guess.

[Atheryl]

I think so, but I haven't get much time to dig into where this take places.

Hi there,
I just had the same issue and it is related to requests 2.11.1.

Temporarily you can revert back to requests 2.10.0 with e.g.
pip install requests==2.10.0

Perhaps this link clarifies the issue a little bit more:

Thanks. So if I understand correctly the values for headers need to be converted to string every time ? This would be likely to be backwards compatible.

I'm not sure when I'll have time to look into this, so if you guys have time, feel free to submit a PR.

[PVince81]

This is already fixed on master apparently 8de5d39 through python3 support, the fix will be in 0.3

[PVince81]

Seems there is more to it: #190

Maybe some Python versions return float values for the timestamp?
