MVC3行动作为一个简单的Web服务

问题描述

我怎么能使用此操作作为一种服务？

How could I use this action as a service?

 public class HomeController : Controller {

     public string GetSomeValue(){
         return "This is some value";
     }
 }

如果我浏览到这个网址，，它返回一个字符串，没有任何形式的任何HTML或标记。

If I navigate to this URL, http://mysite.com/Home/GetSomeValue, it returns a string, without any html or markup of any kind.

那么，是什么让我使用此方法作为返回有意义的服务，比如JSON，我可以从任何地方打电话？

So, what is to keep me from using this method as a service that returned something meaningful, say json, that I could call from anywhere?

如果这是可能的，我会怎么做（说从另一个asp.net网站背后的code）？

And if this is possible, how would I do this (Say from the code behind of another asp.net web site)?

先谢谢了。

推荐答案

100％的没有错，这样做。

100% Nothing wrong with doing this.

一个示例应用程序 - 的NerdDinner - 这是否同样的事情以REST风格加载晚餐

A sample application - NerdDinner - does this very same thing to load dinners restfully.

请参阅控制器和的以JavaScript文件（寻找NerdDinner.FindMostPopularDinners）

See http://nerddinner.codeplex.com/SourceControl/changeset/view/70027#874260 for controller and http://nerddinner.codeplex.com/SourceControl/changeset/view/70027#874293 for javascript file ( look for NerdDinner.FindMostPopularDinners )

例如

C＃

    // AJAX: /Search/GetMostPopularDinners
    // AJAX: /Search/GetMostPopularDinners?limit=5

    [HttpPost]
    public ActionResult GetMostPopularDinners(int? limit)
    {
        var dinners = dinnerRepository.FindUpcomingDinners();

        // Default the limit to 40, if not supplied.
        if (!limit.HasValue)
            limit = 40;

        var mostPopularDinners = from dinner in dinners
                                 orderby dinner.RSVPs.Count descending
                                 select dinner;

        var jsonDinners =
            mostPopularDinners.Take(limit.Value).AsEnumerable()
            .Select(item => JsonDinnerFromDinner(item));

        return Json(jsonDinners.ToList());
    } 

JS

NerdDinner.FindMostPopularDinners = function (limit) {
    $.post("/Search/GetMostPopularDinners", { "limit": limit }, NerdDinner._renderDinners, "json");
}
