楼主最近刚开始学习python QAQ 然后想写一个模拟登陆的脚本现在想登陆 http://10.3.8.241/nav_login 这个网站现在就是请求第一次页面之后 js中有一个checkcode 需要提取出来再加上自己的信息学号密码啥的再POST过去就可以登录但是。。就是运行不成功有点方。。。我看了cookie也是加进去了啊还有不是httplib2也是什么keep-alive这种的下面贴一下浏览器下bp抓的包还有python调试抓的包还有我的代码第一个包： GET /nav_login HTTP/1.1 Host: 10.3.8.241 User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate Referer: http://10.3.8.241/ Cookie: JSESSIONID=8F7DD457FDCB1CBE5B4A770EB5B3F516 Connection: keep-alive Cache-Control: max-age=0 第二个登陆时候的 POST /LoginAction.action HTTP/1.1 Host: gwself.bupt.edu.cn User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate Referer: http://gwself.bupt.edu.cn/nav_login Connection: keep-alive Cookie: JSESSIONID=B1F479C2896813E6F9B23B638F942D7A; Path= Content-Type: application/x-www-form-urlencoded Content-Length: 107 code=&account=XXXXXXXXX&password=xxxxxxxxx&checkcode=381&Submit=%E7%99%BB+%E5%BD%95 再贴一下我开调试显示的抓包内容：第一次： connect: (10.3.8.241, 80) ************ send: 'GET /nav_login HTTP/1.1\r\nHost: 10.3.8.241\r\naccept-language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3\r\naccept-encoding: gzip, deflate\r\naccept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nuser-agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0\r\nconnection: keep-alive\r\nreferer: http://gwself.bupt.edu.cn/nav_login\r\ncookie: \r\n\r\n' reply: 'HTTP/1.1 200 OK\r\n' header: Server: Apache-Coyote/1.1 header: Set-Cookie: JSESSIONID=5352656CD023ACDAD1CDE2FBF9C9A4CD; Path=/ header: Content-Type: text/html;charset=UTF-8 header: Content-Length: 5586 header: Date: Tue, 22 Mar 2016 09:12:27 GMT checkcode="2849"; 2849 {'status': '200', 'content-length': '5586', 'content-location': 'http://10.3.8.241/nav_login', 'set-cookie': 'JSESSIONID=5352656CD023ACDAD1CDE2FBF9C9A4CD; Path=/', 'server': 'Apache-Coyote/1.1', 'date': 'Tue, 22 Mar 2016 09:12:27 GMT', 'content-type': 'text/html;charset=UTF-8'} 第二次的： connect: (gwself.bupt.edu.cn, 80) ************ send: 'POST /LoginAction.action HTTP/1.1\r\nHost: gwself.bupt.edu.cn\r\nContent-Length: 108\r\naccept-language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3\r\naccept-encoding: gzip, deflate\r\naccept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nuser-agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0\r\nconnection: keep-alive\r\nreferer: http://gwself.bupt.edu.cn/nav_login\r\ncookie: JSESSIONID=5352656CD023ACDAD1CDE2FBF9C9A4CD; Path=/\r\n\r\ncode=&account=XXXXXXXX&password=xxxxxxxxxx&checkcode=2849&Submit=%E7%99%BB+%E5%BD%95' reply: 'HTTP/1.1 200 OK\r\n' header: Server: Apache-Coyote/1.1 header: Content-Type: text/html;charset=UTF-8 header: Content-Length: 5586 header: Date: Tue, 22 Mar 2016 09:12:29 GMT No exception was raised. {'date': 'Tue, 22 Mar 2016 09:12:29 GMT', 'status': '200', 'content-length': '5586', 'content-type': 'text/html;charset=UTF-8', 'server': 'Apache-Coyote/1.1'} #获取页面里面的checkcode def getselfcode(page): pattern = re.compile(r'checkcode=\".*\";') match = pattern.search(page) if match: info = match.group() print match.group() else: print "no match" info = info.split('"') return info[1] #登陆 def getselfinfo(): http = httplib2.Http() url = 'http://10.3.8.241/nav_login' user_agent = 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0' values = { 'account' : 'XXXXXXXXX', 'password' : 'xxxxxxxxxxxx', 'code' : '', 'Submit' : '登录', 'checkcode':'1234' } headers = { 'User-Agent' : user_agent, 'Referer' : 'http://gwself.bupt.edu.cn/nav_login', 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'Accept-Language': 'zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3', 'Accept-Encoding': 'gzip, deflate', 'Connection': 'keep-alive', 'Cookie':'' } response, content = http.request(url,'GET', headers = headers) headers['Cookie'] = response['set-cookie'] values['checkcode'] = getselfcode(content) print values['checkcode'] data = urllib.urlencode(values) print response print content url = 'http://gwself.bupt.edu.cn/LoginAction.action' try: response, content = http.request(url,'POST', headers = headers, body = data) except urllib2.URLError,e: if hasattr(e, 'code'): print 'The server couldn\'t fulfill the request.' print 'Error code: ', e.code elif hasattr(e, 'reason'): print 'We failed to reach a server.' print 'Reason: ', e.reason else: print 'No exception was raised.' # everything is fine print response return content 求大神帮忙看看！还有什么其他的代码风格或者用法不好或者习惯不好什么的都请提出来！
