Google-api-python-client: Signature mismatch on get_media for dfareporting

[asiunov]

Environment details

• OS: macOS 10.14.4, linux
• Python version: 3.7.4
• pip version: 19.0.3
• google-api-python-client version: 1.7.11

Steps to reproduce

Sorry, I cannot share the whole code, but the main idea is:

from apiclient import discovery
creds = OAuth2Credentials(...)
http = creds.authorize(http = httplib2.Http())
service = discovery.build('dfareporting', 'v3.3', http=http)  
service.files().get_media(...).execute()

I'm getting this error:

W0813 19:40:45.663586 1 http.py:118] Invalid JSON content from response: b"<?xml version='1.0' encoding='UTF-8'?><Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method.</Message><StringToSign>GET\n\n\n1565725545\nx-goog-api-client:gdcl/1.7.11 gl-python/3.7.4\n/...</StringToSign></Error>"

I've tested the same code with version 1.7.10, and it works. I think this may be a regression introduced here, but I'm not sure: https://github.com/googleapis/google-api-python-client/pull/734

@asiunov Is it possible to know which service you're using?

service = discovery.build('...', 'v3.3', http=http)

just in case someone needs a workaround, try to downgrade the lib:

pip3 uninstall google-api-python-client
pip3 install google-api-python-client==1.7.10

I tested a .get_media on the Drive API, as I don't have Campaign Manager set up.

I uploaded a .txt to Drive and downloaded it. I did not see the error above. :thinking: There may be something different about the DFA Reporting API. I will do some more investigation and get back to you.

The DFA Reporting backend cannot correctly process requests sent with the X-Goog-Api-Client header. Internal Issue 127940526

As a workaround, please use continue to use the previous library version.
google-api-python-client==1.7.10
Thanks for reporting this @asiunov!

[asiunov]

@busunkim96 👍
Thank you!

[busunkim96]

Fix has been deployed on the backend.

[btx]

This is still not working with google-api-python-client==1.8.
API service dfareporting
API version v3.4

@btx Would you mind opening a new issue? Repository maintainers are better able to track new issues than replies to closed issues.

Are you seeing the same error or a different one?
