问题描述
我正在尝试使用python中的feedparser从URL解析RSS feed.
I'm trying to parse RSS feeds from a url using feedparser in python.
>>> 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

如果您转到链接( http ://www.shop.inonit.in/RSSFeedDetails.aspx?PID = 801 )，它显示了很多东西！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来爬网此网站的各个页面，但不能，因为我被重定向到了一些不存在的URL).
I get nothing in the output, while if you go to the link (http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801) it shows a whole lot of stuff!Maybe it is redirecting me to some other page that does't exist (as I tried crawling individual pages of this website using scrapy, but couldn't, since I was redirected to some non-existant url).
任何对此的帮助都会很棒.谢谢！
Any help on this would be great. Thanks!
推荐答案
您是否正在使用代理?如果是这样，请按照以下方式进行操作-
Are you using proxy?If you are, do it this way -
import urllib2, feedparser
proxy = urllib2.ProxyHandler({"http":"proxy:port"})
d = feedparser.parse('http://www.shop.inonit.in/RSSFeedDetails.aspx?PID=801', handlers = [proxy])
