【问题描述】:
我正在编写一个程序,将数据从服务器连续发送到客户端。在这里,我使用时间戳作为示例将其发送给连接的多个客户端。我使用多线程来支持多个客户端。我希望每 10 秒向客户端发送一次时间。但在我的代码中,客户端在收到第一个数据后停止。如何让客户端连续接收数据。我尝试在客户端添加 while 循环,但它无法实现。大家有什么建议
这是示例代码: 服务器端:
import socket
import os
from threading import Thread
import thread
import threading
import time
import datetime
def listener(client, address):
print "Accepted connection from: ", address
with clients_lock:
clients.add(client)
try:
while True:
data = client.recv(1024)
if not data:
break
else:
print repr(data)
with clients_lock:
for c in clients:
c.sendall(data)
finally:
with clients_lock:
clients.remove(client)
client.close()
clients = set()
clients_lock = threading.Lock()
host = socket.gethostname()
port = 10016
s = socket.socket()
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host,port))
s.listen(3)
th = []
while True:
print "Server is listening for connections..."
client, address = s.accept()
timestamp = datetime.datetime.now().strftime("%I:%M:%S %p")
client.send(timestamp)
time.sleep(10)
th.append(Thread(target=listener, args = (client,address)).start())
s.close()
客户端:
import socket
import os
from threading import Thread
import socket
import time
s = socket.socket()
host = socket.gethostname()
port = 10016
s.connect((host, port))
print (s.recv(1024))
s.close()
# close the connection
我的输出:
01:15:10
客户端所需的输出:
01:15:10
01:15:20
01:15:30
#and should go on
