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()
