urllib.request.urlretrieve() 函数不能提交 header 信息?
下载图片时(等同直接访问图片地址)就会触发防盗,返回错误的图片

这个方法也是不行
content = requests.get(picurl, headers =headers).content
with open('F:\\PyDowns\\zhuoku\\demo.jpg', 'wb') as fp:
fp.write(content)
打开 20180425160320(10)
request headers 为
GET 20180425160320(10) HTTP/1.1
Host: com
Proxy-Connection: keep-alive
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9,zh-CN;q=0.8,zh;q=0.7,zh-TW;q=0.6

其中图片的 request headers 为
GET 2019-Bugatti-Chiron-Sport-10 HTTP/1.1
Host: com
Proxy-Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

(由于论坛回复机制删除了 URL )
图片地址 http://bizhi.zhuoku.com/2018/04/25/Bugatti/2019-Bugatti-Chiron-Sport-10.jpg
在这个下 http://www.zhuoku.com/zhuomianbizhi/jing-car/20180425160320(10).htm
htm 可以直接访问不用加 referer,在该页面显示图片正常,图片右击新标签页打开也正常
(浏览器打开正常应该不是封 IP 吧)

代码如下返回了错误的图片
import urllib.request
import requests
import re

headers = {
'Host':'www.zhuoku.com',
'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36',

'Cookie':'cck_lasttime=1535598582789; cck_count=0; bdshare_firstime=1535598583191'
}
url = 'http://www.zhuoku.com/zhuomianbizhi/jing-car/20180425160320(10).htm'
req = requests.get(url, headers = headers)
req.encoding = 'GBK'
html = req.text
picurl = re.findall(r'<img id="imageview" src="(.*?)"', html)[0]
picname = re.findall(r'thumbs/tn_(.*?)"', html)[0]
path = 'F:\\PyDowns\\zhuoku\\' + picname
urllib.request.urlretrieve(picurl, path)
