编码错误解决

1.先在浏览器中检查charset 例如<meta charset="utf-8">，'utf-8'比较常见，也有“gbk”,

​ 对get返回的对象的编码，进行相应的调整

2.尝试使用content属性代替text

3.对于局部乱码（多为中文），例如img标签中的“alt"属性可尝试使用‘’iso-8859-1"进行编码，然后使用‘’gbk"进行 解码

import requests

from bs4 import BeautifulSoup
url_model = 'http://pic.netbian.com/4kdongman/index_{index}.html'
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36'}
pre = 'http://pic.netbian.com'
for i in range(2,6):
    url = url_model.format(index = i)
    response = requests.get(url = url,headers = headers)
    response.encoding = 'gbk'   #----------------  1
    ht = response.text
    exit()
    soup = BeautifulSoup(ht,'lxml')
    tagImg = soup.select('.slist > ul > li > a')
    for j in tagImg:
        imgurl = pre + j['href']
        response1 = requests.get(url = imgurl,headers = headers)
        ht1 = response1.content  #使用text属性乱码（先使用gbk编码没问题）  # -----------2
        soup1 = BeautifulSoup(ht1,'lxml')
        ImgDate = soup1.select('#img > img')[0]
        final_url = 'http://pic.netbian.com' + ImgDate['src']
        imgname = ImgDate['alt'] +'.jpg'  # ---------------3
        imgpath = './图片/' + imgname
        request.urlretrieve(final_url,imgpath)
