python带cookie发包demo

以登录和发布新浪微博信息为例

 1 def sendMsgToSina(username, password,msg):
 2     loginUrl = "http://login.sina.com.cn/sso/login.php";
 3     value = {"service" : "miniblog",
 4              "encoding" : "utf-8",
 5              "gateway" : "1",
 6              "savestate" : "7",
 7              "username" : username,
 8              "password" : password};
 9     cookie = cookielib.CookieJar();
10     opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie));
11     urllib2.install_opener(opener);
12     data = urllib.urlencode(value);
13     #req = urllib2.Request(loginUrl, data);
14     #res = opener.open(req);
15     res = urllib2.urlopen(loginUrl, data);
16     #print res;
17 
18     publishUrl = "http://t.sina.com.cn/mblog/publish.php";
19     #print msg;
20     param = "content=" + msg.encode("utf-8");
21     req = urllib2.Request(publishUrl, param);
22     req.add_header("Referer", "http://t.sina.com.cn/");
23     #opener.open(req);
24     res = urllib2.urlopen(req);
25     print res.read();

方法大概是可以在一个opener里安装一个cookie，下次POST的时候就会自动带上这个cookie。
