我为文件传输编写了以下python代码。它在本地主机环境中运行良好。它在两个不同的物理机器之间发生故障。我得到了文件，但数据不完整。在向客户端发送文件大小时，将字符串转换为long时也存在无效的文本错误。我不明白为什么？在

服务器.pyfrom socket import *

import thread

import os

l = {}

def handler(clientsocket, clientaddr):

print "Accepted connection from: ", clientaddr

while 1:

data = clientsocket.recv(8192)

if not data:

break

else:

print "The following data was received - ",data

l[clientaddr] = data

print l

print "Opening file - ",data

fp = open(data,'r')

size = os.path.getsize(data)

clientsocket.send(str(size))

strng = "hi"

print size

while size > 0:

strng = fp.read(8192)

clientsocket.send (strng)

size = size - 8192

clientsocket.close()

if __name__ == "__main__":

host = 'localhost'

port = 55573

buf = 8192

addr = (host, port)

serversocket = socket(AF_INET, SOCK_STREAM)

serversocket.bind(addr)

serversocket.listen(5)

while 1:

print "Server is listening for connections\n"

clientsocket, clientaddr = serversocket.accept()

thread.start_new_thread(handler, (clientsocket, clientaddr))

serversocket.close()
