内容图文
我已经为此工作了2天,但仍然没有让它正常工作.
我想编写一个使用2个插槽且中间有介质的应用程序
此介质是此脚本,应从socketA读取并写入SocketB并从SocketB读取并写入SocketA.
然而,似乎我无法指出它.
我的脚本在运行时接受连接,但它不允许我在telnet屏幕上输入内容.
我在套接字之间使用2个共享列表来传递数据.
#!/usr/bin/env python
import sys
import arduinoReadThread
import arduinoWriteThread
import socket
import thread
bolt = 0
socketArray=list()
HOST =""
HOST2=""
PORT1 =50115
PORT2 =50125
s1=socket.socket(socket.AF_INET, socket.SOCK_STREAM ) #create an INET, STREAMing socket
s1.bind((HOST,PORT1)) #bind to that port
s1.listen(2) #listen for user input and accept 1 connection at a time.
socketArray.append(s1)
s2=socket.socket(socket.AF_INET, socket.SOCK_STREAM ) #create an INET, STREAMing socket
s2.bind((HOST2,PORT2)) #bind to that port
s2.listen(2) #listen for user input and accept 1 connection at a time.
socketArray.append(s2)
print "sockets set up"
s1ToWriteList = list()
s2ToWriteList = list()
def socketFunctionWrite1():
while(bolt == 0):
client, address = s1.accept()
print "Writing connections"
if len(s1ToWriteList) > 0:
client.send(s1ToWriteList.pop(0))
def socketFunctionRead1():
while(bolt == 0):
client2, address = s2.accept()
f = client2.recv(1024)
print "reading connection"
s1ToWriteList.append(f)
print len(s1ToWriteList)
def socketFunctionWrite2():
while(bolt == 0):
client2, address = s2.accept()
print "Writing connections"
if len(s2ToWriteList) > 0:
client2.send(s2ToWriteList.pop(0))
def socketFunctionRead2():
while(bolt == 0):
client, address = s1.accept()
f = client.recv(1024)
print "reading connection"
s2ToWriteList.append(f)
print len(s2ToWriteList)
def shutDown():
test = raw_input("Quit ?")
if(test =="y"):
bolt = 1
else:
shutDown()
def spreadSockets():
thread.start_new_thread(socketFunctionRead1,())
print "launch 1"
thread.start_new_thread(socketFunctionRead2,())
print "launch 2"
thread.start_new_thread(socketFunctionWrite1,())
print "launch 3"
thread.start_new_thread(socketFunctionWrite2,())
print "launch 4"
spreadSockets()
while(True):
pass
解决方法:
使用您的确切代码,它对我有用.我认为你可能做错的是telnet到错误的IP.不要使用’localhost’或127.0.0.1,您需要使用您的盒子的实际(内部)IP.
如果在linux上,您可以在Windows上查看ifconfig -a或ipconfig / all.
完全运行代码,无需修改(除了删除顶部的2个未知导入)：
推出脚本：
[ 15:01 jon@hozbox.com ~/SO/python ]$./sock.py
sockets set up
launch 1
launch 2
launch 3
launch 4
Writing connections
Writing connections
^CTraceback (most recent call last):
File "./sock.py", line 93, in <module>
time.sleep(1)
KeyboardInterrupt
然后telnet’d：
[ 15:01 jon@hozbox.com ~ ]$telnet 10.10.1.11 50115
Trying 10.10.1.11...
Connected to 10.10.1.11.
Escape character is '^]'.
Hello, World!
Hello 2
^]
telnet> quit
Connection closed.
[ 15:02 jon@hozbox.com ~ ]$telnet 10.10.1.11 50125
Trying 10.10.1.11...
Connected to 10.10.1.11.
Escape character is '^]'.
Hello 50125!
Hi!
^]
telnet> quit
Connection closed.
[ 15:02 jon@hozbox.com ~ ]$
我的内部接口配置(inet addr：10.10.1.11)：
[ 15:07 jon@hozbox.com ~/SO/python ]$ifconfig eth0
eth0 Link encap:Ethernet HWaddr **:**:**:**:**:**
inet addr:10.10.1.11 Bcast:10.10.1.255 Mask:255.255.255.0
...
