Question

我正在编码服务器-客户端程序，其中python为服务器，java为客户端。当用户启动python服务器时，它将创建一个套接字并侦听客户端的连接（活动时，java客户端会每隔17秒尝试连接到服务器）。这样做是为了向服务器用户显示活动客户端的列表。听了20秒后，插座关闭了

服务器用户现在拥有所有活动客户端及其IP的列表。服务器用户现在可以输入一条消息，该消息应该发送到活动的Java客户端之一。因此，他还需要输入应该接收该消息的一个客户端的IP（所有其他连接在传输任何数据之前都会关闭）。为此，服务器在相同的地址上创建了一个新的套接字，但它只说：“ [Errno 98]地址已在使用中”，即使旧套接字已被s.close（）关闭。仅当第一个套接字没有任何连接或我重新启动程序时，才能创建该套接字（对我来说似乎很奇怪...）。我的整个python服务器：

import getpass
from requests import get
import os
import thread
import socket
import sys
import signal
import time

HOST = '0.0.0.0'
PORT = 1979

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print 'Socket created!'


try:
        s.bind((HOST, PORT))
except socket.error as e:
    print(e)
        sys.exit()

print 'Socket bind complete'

s.settimeout(30)
s.listen(10)

print 'Listening...'

timeout = 10

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    try:
            conn, addr = s.accept()
        msg = conn.recv(1024)
        print ('--------------------------------------')
        print (msg) 


    except socket.timeout as e:
        print(e,': Scan finished')
        s.close()
        break

        print 'Client connected: ' + addr[0] + ':' + str(addr[1])
    print ('--------------------------------------')




s.close()

print ('--------------------------------------')
print ('Please enter command')

while True:
    x = raw_input("#").lower()


    if x == "sercom":

        serocom = raw_input('Enter the operation you want to do: ').lower()

        if serocom == "rcos":

            playername = raw_input('Enter command to be executed on the server: ')
            opip = raw_input('Enter serverip (check above): ')

            hosto = '0.0.0.0'
            porto = 1979
            soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

            print 'Socket created!'

            try:
                    soc.bind((hosto, porto))
            except socket.error as e:
                print(e)
                    sys.exit()

这时出现错误。（[Errno 98]：地址已在使用中）

            print 'Socket bind complete'

            soc.settimeout(30)
            soc.listen(10)

            print 'Listening...'

            timeout = 8

            timeout_start = time.time()

            while time.time() < timeout_start + timeout:
                try:
                        conn, addr = soc.accept()
                    if addr[0] != opip:
                        conn.shutdown(socket.SHUT_RDWR)
                        conn.close()
                    else:
                        msg = conn.recv(1024)
                        print ('--------------------------------------')
                        print (msg)
                        conn.send((playername).encode('UTF-8'))
                        print ('Success! The following command has been                             sent to: ' + opip + ':' + playername )
                        print ('--------------------------------------')
                        soc.close()
                        break 
                except socket.timeout as e:
                    print(e,': Server not online or wrong ip')
                    soc.close()
                    break




        else:
            print("kk")
