客户端未从服务器python接收数据

我是Python的新手。我正在编写服务器程序和客户端程序。在这里,服务器扮演着将数据分发到多个客户端的角色。效果很好。我的任务是使用server.py文件从服务器分发数据。每当有任何客户需要时,他只要在笔记本电脑中执行client.py并获取结果即可。但是在这里,服务器开始分发数据。 IP,服务器使用的是127.0.1.1。它不采取网络提供的IP。如何使用局域网提供的IP。当其他计算机上的客户端执行client.py文件时。它显示连接拒绝错误。请注意,我们都连接在LAN中。如何解决它并使客户接收数据。

这是示例客户端代码:

import socket
import os
from threading import Thread


import socket
import time

s = socket.socket()  
host = '127.0.1.1'  
port = 10016
print(host)


s.connect((host, port))
while True:
    print(s.recv(1024))
s.close() 

示例服务器代码:

import socket
import os
from threading import Thread
import thread
import threading
import time
import datetime

def listener(client, address):
    print ("Accepted connection from: ", address)
    with clients_lock:
        clients.add(client)
    try:    
        while True: 
            client.send(a)
            time.sleep(2)   

    finally:
        with clients_lock:
            clients.remove(client)
            client.close()

clients = set()
clients_lock = threading.Lock()

host = socket.gethostname()
port = 10016

s = socket.socket()
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host,port))
s.listen(3)
th = []
print ("Server is listening for connections...")
while True:
    client, address = s.accept()
    timestamp = datetime.datetime.now().strftime("%b %d %Y,%a, %I:%M:%S %p")
    a = "Hi Steven!!!" + timestamp
    th.append(Thread(target=listener, args = (client,address)).start())
s.close()

最后找到答案

在“ / etc / hosts”文件内容中,我有一个IP地址,其主机名映射为“ 127.0.1.1”。这导致名称解析得到127.0.1.1。我评论了这一行。现在可以了。我的局域网中的每个人都可以接收数据

客户代码:

import socket
import os
from threading import Thread
import thread
import threading
import time
import datetime

def listener(client, address):
    print ("Accepted connection from: ", address)
    with clients_lock:
        clients.add(client)
    try:    
        while True: 
            client.send(a)
            time.sleep(2)   

    finally:
        with clients_lock:
            clients.remove(client)
            client.close()

clients = set()
clients_lock = threading.Lock()

host = socket.gethostname()  # it gets ip of lan
port = 10016

s = socket.socket()
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host,port))
s.listen(3)
th = []
print ("Server is listening for connections...")
while True:
    client, address = s.accept()
    timestamp = datetime.datetime.now().strftime("%b %d %Y,%a, %I:%M:%S %p")
    a = "Hi Steven!!!" + timestamp
    th.append(Thread(target=listener, args = (client,address)).start())
s.close()

答案 1 :(得分:0)

配置LAN提供给client.py的IP(LAN中的IP像这样:192.168.122.33)

host = 'ip provided by LAN'
