如何讓我的TCP服務器永久運行？

Question

我有這樣的代碼，我從文檔有：

#!/usr/bin/env python 

import socket 

TCP_IP = '192.168.1.66' 
TCP_PORT = 40000 
BUFFER_SIZE = 20 # Normally 1024, but we want fast response 

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) 
s.bind((TCP_IP, TCP_PORT)) 
s.listen(1) 

conn, addr = s.accept() 

print 'Connection address:', addr 

while True: 
    data = conn.recv(BUFFER_SIZE) 
    if not data: break 
    print "received data:", data 
    conn.send(data) 

conn.close() 

但每次我斷開時間關機，怎麼我讓它運行，直到永遠？

Answer 1

你需要調用一次accept()每個你想要處理的連接。到第一個近似值：

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) 
s.bind((TCP_IP, TCP_PORT)) 
s.listen(1) 

while True:  
    conn, addr = s.accept() 

    print 'Connection address:', addr 

    while True: 
     data = conn.recv(BUFFER_SIZE) 
     if not data: break 
     print "received data:", data 
     conn.send(data) 

    conn.close()

嘗試改變線路

if not data: break 

到

if not data: continue 

這種方式，而不是退出循環，它會等待更多的數據
