该Python脚本创建了一个简单的HTTP服务器，监听8080端口。当接收到请求时，它接收文件名，打开文件，发送HTTP头部信息，然后将文件内容分块发送给客户端。如果文件未找到，它会发送404错误响应。

在这里插入图片描述

#!python
#import socket module

from socket import *
import sys # In order to terminate the program
serverSocket = socket(AF_INET, SOCK_STREAM)
#Prepare a sever socket
serverPort=8080
serverSocket.bind(('',serverPort))
serverSocket.listen(10)
while True:
 	#Establish the connection
	print('Ready to serve...')
	connectionSocket, addr = serverSocket.accept()
	try:
		message = connectionSocket.recv(204800000).decode()
		filename = message.split()[1] 
		f = open(filename[1:]) 
		outputdata = f.read()
		#Send one HTTP header line into socket
		header = ' HTTP/1.1 200 OK\nConnection: close\nContent-Type: text/html\nContent-Length: %d\n\n' % (len(outputdata))
		connectionSocket.send(header.encode()) 

		#Send the content of the requested file to the client
		for i in range(0, len(outputdata)): 
			connectionSocket.send(outputdata[i].encode())
		connectionSocket.send("\r\n".encode())
		connectionSocket.close()
	except IOError:

		#Send response message for file not found
		header = ' HTTP/1.1 404 Not Found'
		connectionSocket.send(header.encode()) 
		#Close client socket
		connectionSocket.close()
serverSocket.close()
sys.exit()#Terminate the program after sending the corresponding data
