Question

我使用python来分析在线广告系统。我尝试连接到服务器但失败了，我在终端中运行的代码模板是：python client.py username portnumber，

这是服务器端的代码：

import sys
import time
import socket
TIMEOUT = 30

class Firefly:
def __init__(self, port):
    self._port = port
def _get_the_dataz(self, s):
    ret = ""
    s.settimeout(TIMEOUT)
    while True:
        data = s.recv(4096)
        if not data:
            break
        ret = ret + data;
    return ret

def _send_command(self, command, retries=3):
    try:
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        #s.connect(('127.0.0.1', self._port))
        s.connect(('localhost', self._port))
        s.send(command)
        ret = self._get_the_dataz(s)
        s.close()
        return ret
    except socket.error as ex:
        print "Firefly timeout, %d retries left" % retries
        print str(ex)

        if retries == 0:
            print "Can't reach firefly on port %d!" % self._port
            raise
        retries -= 1
        time.sleep([30, 10, 2][retries])
        return self._send_command(command, retries)

def get_visual_elements(self, url):
    return self._send_command('GOTO %s' % url)

它总是这样返回：

[errno 111] connection refused
cannot reach server on port 80
traceback(most recent call last):
file "server.py", line 27, in _send_command
  s.connect(('localhost', self._port))
file "server.py", line 224, in meth
  return getattr(self._sock,name)(*args)

然后我尝试“telnet 127.0.0.1 80”，它返回：

无法连接到远程主机，连接被拒绝。

我该怎么办？

ubuntu python socket错误[errno 111]
