Google Reader API Unread Count

问题:

Does Google Reader have an API and if so, how can I get the count of the number of unread posts for a specific user knowing their username and password?

回答1:

This URL will give you a count of unread posts per feed. You can then iterate over the feeds and sum up the counts.

http://www.google.com/reader/api/0/unread-count?all=true

Here is a minimalist example in Python...parsing the xml/json and summing the counts is left as an exercise for the reader:

import urllib import urllib2  username = 'username@gmail.com' password = '******'  # Authenticate to obtain SID auth_url = 'https://www.google.com/accounts/ClientLogin' auth_req_data = urllib.urlencode({'Email': username,                                   'Passwd': password,                                   'service': 'reader'}) auth_req = urllib2.Request(auth_url, data=auth_req_data) auth_resp = urllib2.urlopen(auth_req) auth_resp_content = auth_resp.read() auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x) auth_token = auth_resp_dict["Auth"]  # Create a cookie in the header using the SID  header = {} header['Authorization'] = 'GoogleLogin auth=%s' % auth_token  reader_base_url = 'http://www.google.com/reader/api/0/unread-count?%s' reader_req_data = urllib.urlencode({'all': 'true',                                     'output': 'xml'}) reader_url = reader_base_url % (reader_req_data) reader_req = urllib2.Request(reader_url, None, header) reader_resp = urllib2.urlopen(reader_req) reader_resp_content = reader_resp.read()  print reader_resp_content

It is there. Still in Beta though.

Here is an update to this answer

import urllib import urllib2  username = 'username@gmail.com' password = '******'  # Authenticate to obtain Auth auth_url = 'https://www.google.com/accounts/ClientLogin' #auth_req_data = urllib.urlencode({'Email': username, #                                  'Passwd': password}) auth_req_data = urllib.urlencode({'Email': username,                                   'Passwd': password,                                   'service': 'reader'}) auth_req = urllib2.Request(auth_url, data=auth_req_data) auth_resp = urllib2.urlopen(auth_req) auth_resp_content = auth_resp.read() auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x) # SID = auth_resp_dict["SID"] AUTH = auth_resp_dict["Auth"]  # Create a cookie in the header using the Auth header = {} #header['Cookie'] = 'Name=SID;SID=%s;Domain=.google.com;Path=/;Expires=160000000000' % SID header['Authorization'] = 'GoogleLogin auth=%s' % AUTH  reader_base_url = 'http://www.google.com/reader/api/0/unread-count?%s' reader_req_data = urllib.urlencode({'all': 'true',                                     'output': 'xml'}) reader_url = reader_base_url % (reader_req_data) reader_req = urllib2.Request(reader_url, None, header) reader_resp = urllib2.urlopen(reader_req) reader_resp_content = reader_resp.read()  print reader_resp_content 

Google Reader removed SID auth around June, 2010 (I think), using new Auth from ClientLogin is the new way and it's a bit simpler (header is shorter). You will have to add service in data for requesting Auth, I noticed no Auth returned if you don't send the service=reader.

You can read more about the change of authentication method in this thread.

In the API posted in [1], the "token" field should be "T"
