python scrapy图像管道未下载（301错误）

Question

我想在这个网站上下载这样的网页图片：http://39.moscowfilmfestival.ru/miff39/eng/films/?id=39016。但我收到301错误，图像未下载。我可以毫无问题地下载所有其他数据点，包括images_url。 （我正在重复使用已经在其他类似网站上运行的scrapy代码。）如果我将下载的images_url输入浏览器，它将返回带有图像的页面。但是，页面的URL略有不同，插入正斜杠（/）：

submit: http://39.moscowfilmfestival.ru/upimg/cache/photo/640/6521.jpg
receive: http://moscowfilmfestival.ru/upimg//cache/photo/640/6521.jpg

上述页面的输出日志显示为：

解决问题：

1. 我试图通过插入额外的/来模仿浏览器网址。没有效果。
2. 我试图在蜘蛛类（handle_httpstatus_all = True）和settings.py文件中添加301异常处理程序。没有效果。

有趣的是，我写的蜘蛛的早期版本错误地用一个额外的/（在URL的.ru和miff部分之间）完成了部分url，并且GET和POST请求工作正常。它们与当前版本的蜘蛛中的正确原始页面URL一样工作。

任何帮助真诚地感谢。

我建议你使用urllib库下载任何图像。

import urllib
from urllib import request
url = 'http://39.moscowfilmfestival.ru/upimg/cache/photo/640/6521.jpg'
file_path = r'C:/Users/admin/Desktop/test/6521.jpg'
getPath, headers = urllib.request.urlretrieve(url, file_path)
print(getPath) #This is the image path
