IOError for oauth2.request when used with mod_wsgi + Apache - python

For a third party API, I'm using oauth2 module, I have following code:
Which works well when I use python run.py but throws IOError permission denied when using apache +mod_wsgi configuration.
Here is the error:

Several error working with blogger/google API using python and service account auth

I'm trying to access blogger API using the official Google python library and a service account with a JSON key file made at the Google Developer console.
I'm using Linux Debian.
google-api-python-client=2.65.0
The thing is that I'm getting this traceback:

OSError: [Errno 9] Bad file descriptor
Which point to some sort of error at the OS when opening some file, but I can't imagine which is the file that is causing trouble. The credentials seem like are doing all right when recovered from the json file and at the moment of the exception is just sending this:
b'GET /discovery/v1/apis/blogger/v3/rest HTTP/1.1\r\nHost: www.googleapis.com\r\ncontent-length: 0\r\nuser-agent: Python-httplib2/0.10.3 (gzip)\r\naccept-encoding: gzip, deflate\r\n\r\n'
through the internet. This also seems to do fine from my browser.
The code is here below:

return json.load(keyfile)
key_dict = get_key_dict()
credentials = ServiceAccountCredentials.from_json_keyfile_dict(key_dict, scopes=SCOPES)
# Here it breaks!
service = googleapiclient.discovery.build('blogger', 'v3', credentials=credentials, static_discovery=False,)

print("The posts for %s:" % blog["name"])
request = posts.list(blogId=blog["id"])
while request != None:

if "items" in posts_doc and not (posts_doc["items"] is None):
for post in posts_doc["items"]:
print(" %s (%s)" % (post["title"], post["url"]))
request = posts.list_next(request, posts_doc)
except client.AccessTokenRefreshError:
print(

)
if you check the documentation Authorizing requests and identifying your application you will find that it states that you can use Oauth2 for authorizing a user to the blogger api and api keys. There is no mention of using service account authorization with this api.
To my knowledge as i tried about five years ago this api does not support service account authentication. You will need to use Oauth2.

Invalid and/or missing SSL certificate for URL when calling apiclient.discovery.build

So I'm running my google endpoint locally with dev_appserver.py.
I use the API explorer to test the application.
The code I'm using to create the Service, so I can call the API is the following:
from apiclient.discovery import build
from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials.get_application_default()
service = build('speech', 'v1beta1', credentials=credentials)
I receive an SSL error (Invalid and/or missing SSL certificate), even though when I access the stated URL via browser it works fine (that is, the green padlock shows up).
I'm not sure what changed, but this was working fine not long ago.
I tried to disable SSL checking, but was unable to.

Any ideas what could be causing this problem?
Do I have to "install" or update the SSL certificates used by python?
According to App Engine issue 13477 it seems that some of the certificates found in urlfetch_cacerts.txt that is included in the App Engine Python SDK / gcloud-sdk expired 2017-01-01.
As a temporary workaround, you can replace the contents of <your-cloud-sdk-path>/platform/google_appengine/lib/cacerts/urlfetch_cacerts.txt with https://curl.haxx.se/ca/cacert.pem
To build on the answer by #danielx for those on macOS, this is what worked for me. The path to the certificates for me was:
/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/urlfetch_cacerts.txt
To update it, I used the following steps:
cd /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts
mv urlfetch_cacerts.txt urlfetch_cacerts.bup
curl -o urlfetch_cacerts.txt -k https://curl.haxx.se/ca/cacert.pem
If you don't have curl installed, you can manually download the certificates an move them to the folder above.
Don't forget to restart the App Engine dev server if it is already running.
Got this error on local dev environment as recently as Aug 2017. The fix is to update all urlfetch calls and force validation of the certs:
urlfetch.fetch(url=url, validate_certificate=True)
Did not have to touch the gcloud certs (MacOS). See Issuing an HTTPS request.

Httplib2 exception raised when calling Twilio from python

I'm trying to send an SMS message via Twilio from some Python code running in a Docker container. The container was built from an Ubuntu image with Python 2.7 and the latest twilio-python helper library. When calling the TwilioRestClient messages.create() function, I get the traceback below. Also, I have confirmed via curl that I can reach the url "api.twilio.com" as indicated in the traceback from this container. Any ideas?

How to print HTTP responses in python?

So I am coding this little simple script that I know will not work, but the script itself is running without errors and making a call to www.googleapis.com, so something is happening there. Without seeing the HTTP response I can't know what is wrong, though. The evidence of it actually doing something is because I am in china, and when I run the interpreter there is a time out until I break the script manually :
OUTPUT WITHOUT PROXY :

Now, when I run the interpreter through proxychains and tunnel it it works :

|S-chain|-<>-127.0.0.1:1080-<><>-173.194.208.95:443-<><>-OK
I am new to python, how can get the output of the HTTP error that google is sending me back when I try to connect erroneously to the API ? My code :
import httplib2
import os
from oauth2client import tools
from oauth2client.client import AccessTokenCredentials
#from oauth2client.client import AccessTokenRefreshError
from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload

def authenticate():

flow = AccessTokenCredentials(
acc_token,'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
http = flow.authorize(httplib2.Http())
service = build('youtube', 'v3',http=http)
return(service)

vid = youtube.videos().insert
media_body = MediaFileUpload('1977.mp4', mimetype='video/mp4',

def execute():
youtube = authenticate()
initialize_upload(youtube)
execute()
Use logging: https://developers.google.com/api-client-library/python/guide/logging
Also, you can use Fiddler or Wireshark to analyze the packets being sent to you.

You could try this 3rd party library for BigQuery. It's a thin wrapper around the Google BigQuery API.
To login to BigQuery:
import bigquery as bq
with open('my_key.pem', 'r') as key:
key_content = key.read()
bq_client = bq.get_client(project_id='foo',
service_account='bar',
private_key=key_content)
To submit a load job:
schema = [{'name':'foo', 'type':'STRING'}]
job = bq_client.import_data_from_uris(source_uris=['gs://foo/bar'],
dataset='foo',
table='bar',
schema=schema,
source_format=bq.client.JOB_FORMAT_CSV,
write_disposition=bq.client.JOB_WRITE_TRUNCATE,
field_delimiter=',',
skip_leading_rows=1)
try:
job_resource = bq_client.wait_for_job(job, timeout=60)
except bq.errors.BigQueryTimeoutException:
logging.critical('BigQuery loading timeout.')
Have you tried removing the "http=http" parameter ?
here is an example of the use of the BQ API:
import httplib2
from apiclient.discovery import build
from oauth2client.client import SignedJwtAssertionCredentials
# REPLACE WITH YOUR Project ID
PROJECT_NUMBER = 'XXXXXXXXXXX'
# REPLACE WITH THE SERVICE ACCOUNT EMAIL FROM GOOGLE DEV CONSOLE
SERVICE_ACCOUNT_EMAIL = 'XXXXX#developer.gserviceaccount.com'
# OBTAIN THE KEY FROM THE GOOGLE APIs CONSOLE
# More instructions here: http://goo.gl/w0YA0
f = file('key.p12', 'rb')
key = f.read()
f.close()
credentials = SignedJwtAssertionCredentials(
SERVICE_ACCOUNT_EMAIL,
key,
scope='https://www.googleapis.com/auth/bigquery')
http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2')
datasets = service.datasets()
response = datasets.list(projectId=PROJECT_NUMBER).execute(http)
print 'Dataset list:'
for dataset in response['datasets']:
print '%s' % dataset['datasetReference']['datasetId']
Solved this by specifying the proxy server host and port for the server that I was running this on. While initiating an authorized http service object with the help of credentials, I modified the code as follows:
BEFORE:
http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)
FIX:
http = httplib2.Http(proxy_info = httplib2.ProxyInfo(httplib2.socks.PROXY_TYPE_HTTP, 'your-proxy-host-name', your-proxy-port))
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)
