# # request

根据url获取服务器响应 ，再使用bs4对响应进行解析；

```python
import urllib.request
from typing import List
import bs4
from bs4 import BeautifulSoup
import time

def send_request(url: str) -> bs4.BeautifulSoup:
    req = urllib.request.Request(url)
    # 设置请求头
    req.add_header('User-Agent',
                   'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36')  # set user-agent header
    req.add_header('Cookie','xxx') 
    response_ = urllib.request.urlopen(req)
    # to_html_by_response(response_, "baike.html")
    soup = BeautifulSoup(response_, "html.parser")
    # 给服务器减压
    time.sleep(0.3)
    return soup
```
