python3实现微型的web服务器
人气:0实验目的:用socket 模拟一个微型的web服务器,当py脚本run起后,实微型web server架起了,然后用本地浏览器访问127.0.0.1:8080(web server的ip_port)时web服务器就会将网页内容传给浏览器,实现网页浏览.
sw+sys: python3.7.2 + windows10 64bit
本地准备的server端网页为下载的hao123主页(我已上载并上传,点击这里)
通过这个实验让我学到了:
1. 当get请求一个主页时,要完整的显示一个页面(包括文本、图片、css绚染等)是要get多次请求的。
2. respone回复本地页网,open(filepath, rwa)时要特别的注意
import socket import os curfilepath = os.path.split(os.path.realpath(__file__))[0].replace("\\" , "/") print(f'curfilepath: {curfilepath}') def new_socket_server(new_socket, new_addr): if new_addr[0] != '': print(f'当前客户端{new_addr}已连接上server端. ') # 3.接收信息 file_name = '' request_data = new_socket.recv(1024).decode('utf-8') if request_data != '': print(f'有收到新的信息,信息如下:\n{request_data}') file_name = request_data.splitlines()[0].split(' ')[1] print(f'file_name: {file_name}') if file_name == '/': file_name = '/index.html' print(f'file_name: {file_name}') with open(curfilepath + '/test.txt', 'a+') as f: f.write(file_name + '\n') # 4.回复信息 try: f = open(curfilepath + '/htmltest' + file_name, 'rb') except: response = 'HTTP/1.1 404 NOT FOUND\r\n' response += '\r\n' response += '----------file not found-------' new_socket.send(response.encode('utf-8')) else: html_content = f.read() f.close() response = 'HTTP/1.1 200 OK\r\n' + '\r\n' new_socket.send(response.encode('utf-8')) new_socket.send(html_content) def main(): # 1.创建socket tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 2.连接server server_ip_port = ('127.0.0.1', 8080) tcp_server_socket.bind(server_ip_port) tcp_server_socket.listen(128) while True: print('正在等待client端连接... ...') new_socket, new_addr = tcp_server_socket.accept() new_socket_server(new_socket, new_addr) new_socket.close() if __name__ == '__main__': main()
