这是我的代码:
socketcheck.py
import time
import subprocess
subprocess.Popen(["python", "server.py"])
for i in range(10):
time.sleep(2)
print i
def print_from_server(data):
print data
server.py
import socket
from socketcheck import print_from_server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('localhost',3005))
client_connected = 1
while 1:
s.listen(1)
conn, addr = s.accept()
data = conn.recv(1024)
if data:
client_connected = 0
else: break
if client_connected == 0:
print 'data received'
print_from_server(data)
client_connected = 1
conn.sendall(data)
client.py
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('localhost',3005))
s.sendall('Hello, world')
data = s.recv(1024)
#s.close()
print 'Received', repr(data)
我在这里要做的是,运行socketcheck.py
,它在后台运行server.py
并侦听客户端连接。因此,无论客户端发送什么数据,我都希望将其传递给socketcheck.py
。这有效吗?如果是这样,那我该如何实现呢?
现在,当我尝试运行socketcheck.py
时,for循环无限期地运行。
谢谢:)
编辑:
这最初我尝试作为单个程序,但在客户端连接之前,程序的其余部分不执行(阻塞),setblocking(0)
程序流不会停止但是当客户端连接到服务器它不打印(做任何事情)。服务器代码看起来像这样:
导入套接字 来自socketcheck import print_from_server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('localhost',3005))
s.setblocking(0)
while 1:
try:
s.listen(1)
conn, addr = s.accept()
conn.setblocking(0)
data = conn.recv(1024)
if not data: break
print 'data received'
conn.sendall(data)
except:
print 'non blocking'
print 'the lengthy program continues from here'
答案 0 :(得分:0)
使用多线程可以轻松实现功能:)
