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)

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
