4.爬取数据文件本地保存

import ssl
import requests

url="https://www.bilibili.com"
headers={
    "User-Agent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45."
}


def use_requests(url):
    response=requests.get(url,headers=headers)
    data=response.text
    # print(data)
    file_path="D:/Pycharm/file/bilibili/bilibili.html"
    with open(file_path,"w",encoding="utf-8") as f:
        f.write(data)

if __name__=='__main__':
    use_requests(url)

打开文件：with open(file_path,"w",encoding="utf-8") as f中的w参数说明：

本地windows系统默认编码GBK，python默认编码utf8，设定编码方式不会出现乱码。
