-计算机网络（自顶向下的方法）python实现多线程web服务器

-先编写两个本地的html文件，success.html和fail.html用来测试

-success.html

<!DOCTYPE html>
<html>

	<title></title>
<meta http-equiv="content-type" content="text/html"; charset="utf-8"/>

<style type="text/css">

		font-family: 楷体;

	a{

-fail.html

-web server

from socket import *

import os

'''自定义线程函数'''
def Server(tcpClisock, addr):

    BUFSIZE = 1024
    print('Waiting for the connection：', addr)
    data = tcpClisock.recv(BUFSIZE).decode()
    filename = data.split()[1]
    filename = filename[1:]

    '''当网络质量差没有收到浏览器的访问数据时执行'''
    if filename == "":
        tcpClisock.close()
        print("请输入要访问的文件")

    base_dir = os.getcwd()
    file_dir = os.path.join(base_dir,filename)

    '''当访问的文件在本地服务器存在时执行'''
    if os.path.exists(file_dir):
        f = open(file_dir,encoding = 'utf-8')
        SUCCESS_PAGE = "HTTP/1.1 200 OK\r\n\r\n" + f.read()
        print(SUCCESS_PAGE)
        tcpClisock.sendall(SUCCESS_PAGE.encode())
        tcpClisock.close()
    else:
        FAIL_PAGE = "HTTP/1.1 404 NotFound\r\n\r\n" + open(os.path.join(base_dir, "fail.html"), encoding="utf-8").read()
        print(FAIL_PAGE)
        tcpClisock.sendall(FAIL_PAGE.encode())
        tcpClisock.close()

'''主函数'''
if __name__ == '__main__':

    '''分配IP、端口、创建套接字对象'''
    ADDR = ("", 8080)
    tcpSersock = socket(AF_INET, SOCK_STREAM)
    tcpSersock.bind(ADDR)
    tcpSersock.listen(5)
    print("waiting for connection......\n")
    while True:
        tcpClisock, addr = tcpSersock.accept()
        thread = threading.Thread(target=Server, args=(tcpClisock, addr))
        thread.start()
    tcpSersock.close()

-项目文件目录

-下面开始测试

-在浏览器中输入http://localhost:8080/success.html 因为success.html文件在本地服务器存在所以可以返回success.html页面
- 在这里插入图片描述

-在浏览器中输入http://localhost:8080/index.html 因为index.html文件在本地服务器不存在所以可以返回fail.html页面
在这里插入图片描述

-控制台的打印信息

D:\anaconda\python.exe "C:/Users/Administrator/Desktop/传输与交换技术作业/web多线程服务器/web server.py"
