Question

我是python的新手。所以问题似乎很愚蠢。

我想在python中为客户端和服务器实现一个简单的程序。

server.py是

import socket
#s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, 25, "wlan0"+'\0')
host = socket.gethostname()
port = 12345
s.bind((host,port))
s.listen(5)
while True:
    c,addr = s.accept()
    print "Got connection from",addr
    c.send("Thank you for connecting")
    c.close()

client.py是

import socket
#s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, 25, "wlan0"+'\0')
host = socket.gethostname()
port = 12345
s.connect((host,port))
print s.recv(1024)
s.close

问题是编译器显示错误＆＃34;不允许操作＆＃34;。我尝试以root身份执行程序。错误消失了，但没有建立客户端和服务器连接。

在添加此行之前一切正常

   s.setsockopt(socket.SOL_SOCKET, 25, "wlan0"+'\0')

希望有人可以解决我的问题。我想通过wlan0接口连接客户端和服务器。

感谢。

服务器PY：

import socket
import fcntl
import struct
#s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)




def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,  # SIOCGIFADDR
        struct.pack('256s', ifname[:15])
    )[20:24])

host = get_ip_address("eth0")#replace with "wlan0"
port = 12345
s.bind((host,port))
s.listen(5)
while True:
    c,addr = s.accept()
    print "Got connection from",addr
    c.send("Thank you for connecting")
    c.close()

客户PY：

import socket
import fcntl
import struct

def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,  # SIOCGIFADDR
        struct.pack('256s', ifname[:15])
    )[20:24])

#s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = get_ip_address("eth0")#replace with "wlan0"
port = 12345
s.connect((host,port))
print s.recv(1024)
s.close

check this。 警告：服务器py在shell上运行（＆＃34; python server.py＆＃34;），客户端在空闲时运行。

无法在python中使用setsockopt进行连接
