Yahoo Pipes:可以从feedproxy.google.com网址获取真实网址吗? [英] Yahoo Pipes: Possible to retrieve get real url from feedproxy.google.com url?

问题描述

使用Yahoo Pipes，是否可以轮询此URL
http://feedproxy.google.com/~r/Techcrunch/〜3/P-_qWQXyAPU/
并获取真实的URL
http://www.techcrunch.com/2009/12/08/build-it-with-me
返回管道?

Using Yahoo Pipes, is it possible to poll this url
http://feedproxy.google.com/~r/Techcrunch/~3/P-_qWQXyAPU/
and get the real url
http://www.techcrunch.com/2009/12/08/build-it-with-me
returned to the pipe?

理想情况下，该解决方案将具有足够的通用性，可以轮询任何URL并获取其真实" URL. 我认为YQL可能会实现，但不确定.

Ideally the solution would be generic enough to poll any url and get it's "real" url. I'm thinking it might be possible with YQL but am not sure.

如果使用 y.rest() 进行呼叫，则可以使用 followRedirects(false) 像这样:

If you use y.rest() to make the call you can use followRedirects(false) like this:

use 'http://javarants.com/yql/javascript.xml'as j; select * from j where code='response.object =
y.rest("http://feedproxy.google.com/~r/Techcrunch/~3/P-%5FqWQXyAPU/").followRedirects(false).get().headers.location;'
