20人文件服务器拒绝了连接,Python socket.error:[Errno 111]连接被拒绝

我正在尝试使用套接字编写一个文件传输程序.代码的服务器端运行正常.但是,在客户端,我收到以下错误

Traceback (most recent call last):

File "client.py", line 54, in

uploadFiles(directory)

File "client.py", line 36, in uploadFiles

transferFile(fname)

File "client.py", line 13, in transferFile

cs.connect((HOST, 36258))

File "/usr/lib/python2.7/socket.py", line 224, in meth

return getattr(self._sock,name)(*args)

socket.error: [Errno 111] Connection refused

我的代码如下

import os

import socket

def transferFile(fname):

HOST = '127.0.0.1'

CPORT = 36258

MPORT = 36250

FILE = fname

cs = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

cs.connect((HOST, 36258))

cs.send("SEND " + FILE)

cs.close()

ms = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

ms.connect((HOST, MPORT))

f = open(FILE, "rb")

data = f.read()

f.close()

ms.send(data)

ms.close()

def uploadFiles(directory):

home = os.getenv("HOME")

folder = str(home + "/" + directory)

os.chdir(folder)

dirList = os.listdir(folder)

print dirList

for fname in dirList:

if fname.endswith('.bin'):

transferFile(fname)

os.chdir(os.getenv("HOME"))

directory = "testdownload"

if not os.path.exists(directory):

os.makedirs(directory)

os.chdir(directory)

uploadFiles(directory)

我试图在谷歌和Stack Overflow上的其他帖子上寻求帮助,但没有一个帮助.有人可以帮帮我吗？行号可能不同,因为我只粘贴了部分代码
