Why is Google telling me that my REST httplib2 code is malformed?

StackOverflow https://stackoverflow.com/questions/11008377

Question 

import httplib2
from urllib import urlencode
h = httplib2.Http()
h.add_credentials('zackster@gmail.com', 'PassWord')
data = dict(key="ThisIsMyApiKeyICopiedAndPastedIt")
resp, content = h.request("https://www.googleapis.com/calendar/v3/users/me/calendarList", "GET", urlencode(data), headers={'content-type':'text/plain'})



>>> resp
{'date': 'Wed, 13 Jun 2012 04:33:03 GMT', 'status': '400', 'content-length': '925', 'content-type': 'text/html; charset=UTF-8', 'server': 'GFE/2.0'}

>>> print content

Solution

I'm guessing, but you are sending your API key as POST data. It needs to be appended to the URL as a query string. This is the HTTP request generated by your code:

GET /calendar/v3/users/me/calendarList HTTP/1.1
Host: www.googleapis.com
Content-Length: 36
content-type: text/plain
accept-encoding: gzip, deflate
user-agent: Python-httplib2/$Rev$

key=ThisIsMyApiKeyICopiedAndPastedIt

Rather (if my guess is right) it should be:

GET /calendar/v3/users/me/calendarList?key=ThisIsMyApiKeyICopiedAndPastedIt HTTP/1.1
Host: localhost:1234
content-type: text/plain
accept-encoding: gzip, deflate
user-agent: Python-httplib2/$Rev$

So your code should be modified to something like this:

url = 'https://www.googleapis.com/calendar/v3/users/me/calendarList'
uri = '%s?%s' % (url, urlencode(data))
resp, content = h.request(uri, "GET", headers={'content-type':'text/plain'})
