用socket 模擬一個(gè)微型的web服務(wù)器，當(dāng)py腳本run起后，實(shí)微型web server架起了，然后用本地瀏覽器訪問127.0.0.1:8080(web server的ip_port)時(shí)web服務(wù)器就會(huì)將網(wǎng)頁內(nèi)容傳給瀏覽器，實(shí)現(xiàn)網(wǎng)頁瀏覽

1. 當(dāng)get請(qǐng)求一個(gè)主頁時(shí)，要完整的顯示一個(gè)頁面（包括文本、圖片、css絢染等）是要get多次請(qǐng)求的。

2. respone回復(fù)本地頁網(wǎng)，open(filepath, rwa)時(shí)要特別的注意

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'當(dāng)前客戶端{(lán)new_addr}已連接上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}')
