http = httplib2.Http()
url= ''
body ={'USERNAME': 'foo', 'PASSWORD': 'bar'}
headers = {'Content-type': 'application/x-www-form-urlencoded'}
response, content = http.request(url, 'POST', headers=headers, body=urllib.urlencode(body))
headers = {'Cookie': response['set-cookie']}
url = ''
response, content = http.request(url, 'GET', headers=headers)

httplib2文档：  
从http post method的response里拿到cookie，然后之后用这个cookie与服务器交互。
