分享一段tornado登陆豆瓣的代码，只简单实现了登陆，并没有实现异步登陆。需要的网友可以自己将代码完善一下。
直接上代码：
#coding=utf8
import settings
import urllib
from tornado import httpclient
import json
class douban:
authurl = 'https://www.douban.com/service/auth2/'
user_info_url = 'https://api.douban.com/v2/user/~me'
def get_authorization_code(self):
params = {
"client_id":settings.oauth2['douban']['key'],
"redirect_uri":settings.oauth2['redirect_url'],
"response_type":"code",
"scope":"douban_basic_common",
}
return self.authurl+'auth?'+urllib.urlencode(params)
def get_access_token(self,code):
params = {
"client_id":settings.oauth2['douban']['key'],
"client_secret":settings.oauth2['douban']['sercet'],
"redirect_uri":settings.oauth2['redirect_url'],
"grant_type":"authorization_code",
"code":code,
}
url = self.authurl+'token'
http_client = httpclient.HTTPClient()
req = httpclient.HTTPRequest(url,method='POST',body=urllib.urlencode(params))
response = http_client.fetch(req)
return json.loads(response.body)
def get_user_info(self,access_token):
url = 'https://api.douban.com/v2/user/~me'
http_client = httpclient.HTTPClient()
req = httpclient.HTTPRequest(url,headers={"Authorization":"Bearer "+access_token})
response = http_client.fetch(req)
return json.loads(response.body)
