 使用requests请求网页时，返回的页面信息有时是乱码，如下代码

headers = {
    'user-agent': 'mozilla/5.0 (windows nt 6.1; wow64) applewebkit/537.36 (khtml, like gecko) chrome/65.0.3325.181 safari/537.36'
}
def get_all(url,key):
    params = {
        'keyword':key,
        'enc':'utf-8'
    }
    response = requests.get(url=url,params=params,headers=headers)

    with open('jd.html','w',encoding='utf-8') as f:
        f.write(response.text)



if __name__ == '__main__':
    key = input('输入搜索内容：')
    url = 'https://search.jd.com/search?'
    get_all(url,key)

返回的部分内容；

<div class="p-name p-name-type-2">
            <a target="_blank" title="极地传说短袖t恤男夏季韩版潮流短袖男士半袖t恤圆领休闲修身大码五分袖潮牌青年学生t恤衣服男装 430黄色 m" href="//item.jd.com/51029271063.html" onclick="searchlog(1,51029271063,8,1,'','flagsclk=1077936264')">
                <em>极地传说短袖t恤<font class="skcolor_ljg">男</font>夏季韩版潮流短袖男士半袖t恤圆领休闲修身大码五分袖潮牌青年学生t恤衣服<font class="skcolor_ljg">男装</font> 430黄色 m</em>
                <i class="promo-words" id="j_ad_51029271063"></i>
            </a>
        </div>

解决方法和思路过程；

代码；

def get_all(url,key):
    params = {
        'keyword':key,
        'enc':'utf-8'
    }
    response = requests.get(url=url,params=params,headers=headers)
    # 打印出所请求页面返回的编码方式
    print(response.encoding)
    # response.apparent_encoding是通过内容分析出的编码方式，这里是urf-8
    print(response.apparent_encoding)
    # 转码
    content = response.text.encode(response.encoding).decode(response.apparent_encoding)
    print(content)
    with open('jd.html','w',encoding='utf-8') as f:
        f.write(content)



if __name__ == '__main__':
    key = input('输入搜索内容：')
    url = 'https://search.jd.com/search?'
    get_all(url,key)

控制台输出（部分）；
