無法解析rss提要

Question

我想從python中使用feedparser解析來自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    
<h2> <i>Attempted to divide by zero.</i> </h2></span>\n\n   <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">\n\n   <b> Description: </b>An unhandled exception occurred during the execution of the current web request.

我什麼也沒得到輸出，而如果你去鏈接（http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801）它顯示了一大堆的東西！ 也許它會將我重定向到其他一些不存在的頁面（因爲我試圖使用scrapy抓取本網站的各個頁面，但無法執行，因爲我被重定向到了一些不存在的url）。

對此的任何幫助將是偉大的。謝謝！

你使用代理服務器嗎？ 如果你是，做這種方式 -

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