python httplib问题

zchao4251500

我想写一个IP扫描器。代码如下

#/usr/bin/env python
# -*- coding: utf-8 -*-
import threading,httplib,time,sys
class Mythread(threading.Thread):
        def __init__(self):
                threading.Thread.__init__(self)
        def run(self,host=sys.argv[1]):
                self.host = host
                ports = [80,443,4848,8080,8090,8000,8082,8888,9043,7001,7002,7003,7080,8443,9060,9440,9090,8081,9043,9080,81,18100,9956]
                for port in ports:
                        conn = httplib.HTTPConnection(self.host,port,True,6)
                        i_headers = {"User-Agent": "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.1) Gecko/20090624 Firefox/3.5","Accept": "text/plain"}
                        conn.request('GET','/',headers = i_headers)
                        r1 = conn.getresponse()
                        print r1.status
                        conn.close()
if __name__ == '__main__':
        #global host
        Mythread().start()

但是一运行。

貌似只访问了一个端口。

我的想法是：一次访问每个端口 打印出http状态响应码。

错误如下:


D:\script>python dump.py 220.181.111.147
200
Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Python27\lib\threading.py", line 551, in __bootstrap_inner
    self.run()
  File "dump.py", line 13, in run
    conn.request('GET','/',headers = i_headers)
  File "C:\Python27\lib\httplib.py", line 958, in request
    self._send_request(method, url, body, headers)
  File "C:\Python27\lib\httplib.py", line 992, in _send_request
    self.endheaders(body)
  File "C:\Python27\lib\httplib.py", line 954, in endheaders
    self._send_output(message_body)
  File "C:\Python27\lib\httplib.py", line 814, in _send_output
    self.send(msg)
  File "C:\Python27\lib\httplib.py", line 776, in send
    self.connect()
  File "C:\Python27\lib\httplib.py", line 757, in connect
    self.timeout, self.source_address)
  File "C:\Python27\lib\socket.py", line 571, in create_connection
    raise err
timeout: timed out

不知道怎么回事了。如果有知道的 还请帮忙解决下 谢谢了

没响应，超时了，试一下用
try：
   conn.request('GET','/',headers = i_headers)
