我刚刚为客户端/服务器示例复制了此代码:

当我运行代码时出现此错误:

OSError: [Errno 99] Cannot assign requested address

服务器:

# server.py 
import socket                                         
import time

# create a socket object
serversocket = socket.socket(
            socket.AF_INET, socket.SOCK_STREAM) 

# get local machine name
host = socket.gethostname()                           

port = 9999                                           

# bind to the port
serversocket.bind((host, port))                                  

# queue up to 5 requests
serversocket.listen(5)                                           

while True:
    # establish a connection
    clientsocket,addr = serversocket.accept()      

    print("Got a connection from %s" % str(addr))
    currentTime = time.ctime(time.time()) + "\r\n"
    clientsocket.send(currentTime.encode('ascii'))
    clientsocket.close()

客户端:

# client.py  
import socket

# create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 

# get local machine name
host = socket.gethostname()                           

port = 9999

# connection to hostname on the port.
s.connect((host, port))                               

# Receive no more than 1024 bytes
tm = s.recv(1024)                                     

s.close()

print("The time got from the server is %s" % tm.decode('ascii'))

答案 0 :(得分:1)

host = socket.gethostname()替换为host = '127.0.0.1',它应该有效。
