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)
