无法解析 RSS 提要

Question

我正在尝试使用 python 中的 feedparser 解析来自 url 的 RSS 提要。

>>> import feedparser 
>>> d = feedparser.parse('http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801')
>>> d
{'feed': {'summary': u'<span><h1>Server Error in \'/mobile\' Application.<hr color="silver" size="1" width="100%" /></h1>\n\n

我在输出中一无所获，而如果您转到链接 (http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801)，它会显示很多东西！ 也许它会将我重定向到其他不存在的页面（因为我尝试使用 scrapy 抓取该网站的各个页面，但由于我被重定向到了一些不存在的 url，所以不能）。

对此的任何帮助都会很棒。谢谢！

你在使用代理吗？ 如果你是，就这样做吧-

import urllib2, feedparser
proxy = urllib2.ProxyHandler({"http":"proxy:port"})
d = feedparser.parse('http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801', handlers = [proxy])
