python爬虫问题01--‘gbk‘，utf-8

被爬虫的网页是"UTF-8"格式的编码，但是我在保存内容时

from urllib.request import urlopen

def get_url():
    url = 'https://www.hao123.com/'
    resp = urlopen(url)
    with open('baidu.html', mode='w') as file:
        content = resp.read()
        # print(f)
        # file.write(f)
        file.write(content.decode("UTF-8"))
        print('file is done!!')


if __name__ == '__main__':
    get_url()

出现了下面的错误

UnicodeEncodeError: 'gbk' codec can't encode character 'u2022' in position 252532: illegal multibyte sequence

原因是windows默认打开文件的时候采用的是‘gbk'编码，这里我们修改其编码的方式为’UTF-8‘即可

with open('baidu.html', mode='w', encoding="utf-8") as file:

在打开的这行函数加了encoding="utf-8"
