你有一个ASP.NET MVC操作方法做了什么聪明的事情 [英] What clever things have you done with an ASP.NET MVC Action method

问题描述

在ASP.NET MVC控制器操作方法主要用于处理业务操作，但它可以用于其它更多的。

The ASP.NET MVC controller action methods are primarily used for handling 'business' operations but it can be used for lots more.

我认为这将是有趣的，看看有什么创意，有用的东西的人创造了动作，它们可以是实际的或有用的人。

I thought it would be fun to see what creative, useful things people have created actions for that may be practical or useful for others.

下面是我的贡献：

JavaScript文件连接符 - 来减少HTTP请求数：

Javascript file concatenator - to reduce number of http requests:

    [OutputCache(Duration = 5 * 60, VaryByParam="")]  // DONT USE "None" here *
    public ContentResult RenderJavascript(){

        StringBuilder js = new StringBuilder();
        StringWriter sw = new StringWriter(js);

        // load all my javascript files
        js.AppendLine(File.ReadAllText(Request.MapPath("~/Scripts/jquery.hoverIntent.minified.js")));
        js.AppendLine(File.ReadAllText(Request.MapPath("~/Scripts/jquery.corner.js")));
        js.AppendLine(File.ReadAllText(Request.MapPath("~/Scripts/rollingrazor.js")));

        return new ContentResult()
        {
            Content = js.ToString(),
            ContentType = "application/x-javascript"
        };
    }

该地图的路线吧：

  // javascript
  routes.MapRoute(
     "js-route",
     "dynamic/js",
     new { controller = "Application", action = "RenderJavascript" }
  );

这是你的母版页参考吧：

Refer to it from your master page :

    <script type="text/javascript" src="/dynamic/js"></script>

被警告我设置为输出缓存，所以如果你改变你的JS和刷新页面，您可能要禁用缓存！

Be warned I've set a cache for the output, so if you're changing your JS and refreshing the page you might want to disable the cache!

我仅仅指刚要回来，并找出如何gzip压缩了。

I jsut need to come back and figure out how to gzip it.

* 你不应该使用的VaryByParam =无，因为这会导致Vary标头进行发送，其中的使浏览器回过头去检查是否有新版本。如果你真的有改变你的js的内容，那么你的用户只是布莱恩不得不等待5分钟吧！

* You shouldn't use VaryByParam="None" because that causes the Vary header to be send, which causes the browser to go back and check for a new version. If you really have to change your js content then your users are just goin to have to wait 5 minutes for it!

推荐答案

难道一个 HTTP 301重定向算聪明吗？

public class PermanentRedirectResult : ActionResult
{
    public string Url { get; set; }

    public PermanentRedirectResult(string url)
    {
        if (string.IsNullOrEmpty(url))
        {
            throw new ArgumentException("url is null or empty", "url");
        }
        this.Url = url;
    } 

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }
        context.HttpContext.Response.StatusCode = 301;
        context.HttpContext.Response.RedirectLocation = Url;
    }
}
