我有一个控制器动作,返回大量的动态
JavaScript(一次服务到客户端),我已经启用了GZip压缩.我想做的一件事是阅读执行的结果流并对其应用JS缩小.

是否可以使用动作过滤器属性执行此操作.我想我的问题归结为 – 假设我的minifier需要一串JavaScript,有没有办法将执行结果拉出View(view).ExecuteResult(ControllerContext)？

解决方法

我认为YUI Compressor for .NET将完全满足您的需求.

编辑：上面错了,因为我误解了这个问题.下面的代码将安装一个响应过滤器,允许您操作输出,在这种情况下,它只是删除换行符.

希望这可以帮助.

public class HomeController : Controller
{
    [Minify]
    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";

        return View();
    }
}

public class Minify : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        //You can check if the content type is CSS/JS here and prevent the filter running on HTML pages 

        filterContext.HttpContext.Response.Filter = new MinifyFilter(filterContext.HttpContext.Response.Filter);

        base.OnActionExecuting(filterContext);
    }
}

public class MinifyFilter : MemoryStream
{
    private StringBuilder outputString = new StringBuilder();
    private Stream outputStream = null;

    public MinifyFilter(Stream outputStream)
    {
        this.outputStream = outputStream;
    }

    public override void Write(byte[] buffer,int offset,int count)
    {
        outputString.Append(Encoding.UTF8.GetString(buffer));
    }

    public override void Close()
    {
        //Call the minifier here,your data is in outputString
        string result = outputString.ToString().Replace(Environment.NewLine,string.Empty);

        byte[] rawResult = Encoding.UTF8.GetBytes(result);
        outputStream.Write(rawResult,rawResult.Length);

        base.Close();
        outputStream.Close();
    }
}
