python获取服务器进程 python获取服务器文件

下面的示例演示如何通过tcp从服务器下载文件。

客户代码：

import socket
import os
HOST = 'localhost'
PORT = 1024
downloadDir = "/tmp"
filename = raw_input('Enter your filename: ')
socket1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket1.connect((HOST, PORT))
socket1.send(filename)
with open(os.path.join(downloadDir, filename), 'wb') as file_to_write:
while True:
data = socket1.recv(1024)
if not data:
break
file_to_write.write(data)
file_to_write.close()
socket1.close()

服务器代码：

import socket
HOST = 'localhost'
PORT = 1024
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.bind((HOST, PORT))
socket.listen(1)
while (1):
conn, addr = socket.accept()
reqFile = conn.recv(1024)
with open(reqFile, 'rb') as file_to_send:
for data in file_to_send:
conn.sendall(data)
conn.close()
socket.close()

注意：服务器代码不健壮，当文件不存在时将崩溃。你应该根据你的需要修改上面的例子。
