python3：爬取的内容包含中文，输出后乱码的问题

需求：想要实现这样的功能：用户输入喜欢的电影名字，程序即可在电影天堂https://www.ygdy8.com爬取电影所对应的下载链接，并将下载链接打印出来

遇到的问题：获取磁力的链接中包含中文，打印出来后乱码

解决办法：手动指定编码方式：

if res.encoding == ‘ISO-8859-1‘:
    encodings = requests.utils.get_encodings_from_content(res.text)
    if encodings:
        encoding = encodings[0]
    else:
        encoding = res.apparent_encoding
else:
    encoding = res.encoding
encode_content = res.content.decode(encoding, ‘replace‘).encode(‘utf-8‘, ‘replace‘)

# 想要实现这样的功能：用户输入喜欢的电影名字，程序即可在电影天堂https://www.ygdy8.com爬取电影所对应的下载链接，并将下载链接打印出来

import requests
from bs4 import BeautifulSoup
from urllib.request import pathname2url

# 为躲避反爬机制，伪装成浏览器的请求头
headers = {‘User-Agent‘: ‘Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36 OPR/65.0.3467.78 (Edition Baidu)‘}

# 获取电影磁力链接
def getMovieDownloadLink(filmlink):
    res = requests.get(filmlink, headers=headers)
    if res.status_code == 200:

        # 请求后的内容中文乱码处理办法：
        # 当response编码是‘ISO-8859-1’，我们应该首先查找response header设置的编码；如果此编码不存在，查看返回的Html的header设置的编码
        if res.encoding == ‘ISO-8859-1‘:
            encodings = requests.utils.get_encodings_from_content(res.text)
            if encodings:
                encoding = encodings[0]
            else:
                encoding = res.apparent_encoding
        else:
            encoding = res.encoding
        encode_content = res.content.decode(encoding, ‘replace‘).encode(‘utf-8‘, ‘replace‘)

        soup = BeautifulSoup(encode_content, ‘html.parser‘)
        Zoom = soup.select_one(‘#Zoom‘)
        fileurl = Zoom.find(‘table‘).find(‘a‘).text
        with open(‘./17-电影天堂磁力.txt‘,‘a‘, newline=‘‘) as file:
            file.write(fileurl + ‘\n‘)

    else:
        print(‘电影链接：{}请求失败！‘.format(filmlink))

def main():
    dyurl = ‘https://www.ygdy8.com‘
    # movie = input(‘请输入电影名称：‘)
    movie = ‘沉睡魔咒‘
    movie = movie.encode(‘gbk‘)
    url = ‘http://s.ygdy8.com/plus/s0.php?typeid=1&keyword={0}‘.format(pathname2url(movie))
    res = requests.get(url, headers=headers)
    if res.status_code == 200:
        htmltext = res.text
        soup = BeautifulSoup(htmltext, ‘html.parser‘)
        co_content8 = soup.find(‘div‘, class_=‘co_content8‘)
        tables = co_content8.find(‘ul‘).find_all(‘table‘)
        if len(tables) <= 0:
            print(‘没有找到相关的资源，可到站点上搜索 {0}‘.format(dyurl))
        else:
            for table in tables:
                filmlink = dyurl + table.find(‘a‘)[‘href‘]
                getMovieDownloadLink(filmlink)

    else:
        print(‘请求失败！‘)

main()

结果：
