[Use this form for both apiclient and oauth2client issues] I have a Google Service Account which is being used by an installed application to upload files into GCS, and then send a POST request to a GAE Module.

The upload of files to GCS works great, but when the credentials of the default service account are used to send a POST to a GAE Module (in its yaml file the login for the GAE Module handler is declared to be required), the 'Server presented certificate does not match' the URI

After searching this site, as well as using Google Search, I have not discovered a solution to this problem, and not much general info about this type of problem. I'm using the latest version of the Goolge API Python client (1.9.24)

Here's the stack trace:

Traceback (most recent call last): File "gcs_bq_file_uploader.py", line 302, in main gae_endpoint = discovery.build(config._GAE_API, config._GAE_API_VERSION, discoveryServiceUrl=dis covery_url, http=http_auth) File "C:\Python27\Lib\site-packages\oauth2client\util.py", line 137, in positional_wrapper return wrapped(*args, **kwargs) File "C:\Python27\lib\site-packages\google_api_python_client-1.4.1-py2.7.egg\googleapiclient\disco very.py", line 197, in build resp, content = http.request(requested_url) File "C:\Python27\Lib\site-packages\oauth2client\client.py", line 562, in new_request redirections, connection_type) File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1608, in request (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, re directions, cachekey) File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1350, in _request (response, content) = self._conn_request(conn, request_uri, method, body, headers) File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1272, in _conn_request conn.connect() File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1047, in connect 'host %s: %s' % (hostname, cert), hostname, cert) CertificateHostnameMismatch: Server presented certificate that does not match host www.ethereal-shap e-89619.appspot.com: {'notAfter': 'Oct 13 00:00:00 2015 GMT', 'subjectAltName': (('DNS', '.appspot. com'), ('DNS', '.thinkwithgoogle.com'), ('DNS', '.withgoogle.com'), ('DNS', 'appspot.com'), ('DNS' , 'thinkwithgoogle.com'), ('DNS', 'withgoogle.com')), 'subject': ((('countryName', u'US'),), (('stat eOrProvinceName', u'California'),), (('localityName', u'Mountain View'),), (('organizationName', u'G oogle Inc'),), (('commonName', u'.appspot.com'),))} INFO:root:None INFO:root:------------------------------------------------------------

What steps will reproduce the problem? 1. Running the code 2. 3.

What is the expected output? What do you see instead? See stack trace shown above. Source code is attached. And the yaml of the target GAE Module is included as well (if that is of any help).

What version of the product are you using? On what operating system? Product version 1.9.24. Windows 7 Professional 32-bit

Please provide any additional information below. This is my first attempt at sending a POST request to a GAE Module from an installed application, so my guess is I've got an easily detected bug in my code, or I'm entirely missing some critical bit of code.

FYI, I have worked past this problem by making the following change to the code: http_auth = credentials.authorize(httplib2.Http()) is now: http_auth = credentials.authorize(httplib2.Http(disable_ssl_certificate_validation=True))

But, doing so has resulting in the repressing the prior certificate error message, while triggering another error (likely caused by my code, which I am now investigating):

Traceback (most recent call last): File "gcs_bq_file_uploader.py", line 304, in main gae_endpoint = discovery.build(config._GAE_API, config._GAE_API_VERSION, discoveryServiceUrl=dis covery_url, http=http_auth) File "C:\Python27\Lib\site-packages\oauth2client\util.py", line 137, in positional_wrapper return wrapped(*args, **kwargs) File "C:\Python27\lib\site-packages\google_api_python_client-1.4.1-py2.7.egg\googleapiclient\disco very.py", line 197, in build resp, content = http.request(requested_url) File "C:\Python27\Lib\site-packages\oauth2client\client.py", line 562, in new_request redirections, connection_type) File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1608, in request (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, re directions, cachekey) File "C:\Python27\Lib\site-packages\httplib2__init__.py", line 1403, in _request redirections=redirections - 1) File "C:\Python27\Lib\site-packages\oauth2client\client.py", line 552, in new_request headers['user-agent'] = self.user_agent + ' ' + headers['user-agent'] TypeError: can only concatenate tuple (not "str") to tuple

Hopefully, I'll resolve this one shortly.
