Umbraco-检查请求是否为XmlHttpRequest

Question

I'm doing an AJAX feature for my Umbraco website.

Basically what I'm trying to do is when someone requests for http://mysite.com/news with the XmlHttpRequest header then I want Umbraco to return JSON of the following page.

What I've been trying to do is finding the right place to check for the header in Umbraco. Basically I want to override or inherit some class where I could check the header and return the page in Json or HTML depending on the header.

I'm using Umbraco 4.7.0 (1.0.4090.21631)

Any feedback would be more than welcome! Thanks!

Answer 1

You should check the Content-Type header from server side logic. Your Javascript should be specifying a Content-Type like application/json .

Answer 2

I'd probably use the URL Rewriting module for IIS7 to detect the content-type in the request, then redirect to the same URL with /jsonTemplate on the end of it. You would then create a masterpage called jsonTemplate, with a single macro inside it, which would return your JSON.

This is common for Umbraco - specifying a separate template with a separate macro to return a different view of the same content. Check out http://blog4umbraco.codeplex.com/SourceControl/changeset/view/68424#1138733 for an example of an XSLT macro that returns RSS using this approach.
