Set Cache-Control：no-cache对GET请求 [英] Set Cache-Control: no-cache on GET requests

问题描述

我尝试在GET请求的响应中设置Cache-Control标头。

I am trying to set the Cache-Control header on the response for GET request.

这样做与OPTIONS请求：

This works, with OPTIONS requests:

PreRequestFilters.Add((httpRequest, httpResponse) =>
{
   if (httpRequest.HttpMethod == "OPTIONS")
   {
      httpResponse.AddHeader("Cache-Control", "no-cache");
      httpResponse.EndServiceStackRequest();
   }
});

这不适用于GET请求：

This does not work, with GET requests:

ResponseFilters.Add((httpRequest, httpResponse, dto) =>
{
   httpResponse.AddHeader("Cache-Control", "no-cache");
});

过滤器正在工作...也可以使用上面的方法。

The filters are working... Also I am able to add my own headers to the response using the above method.

我使用的是3.9.58。

I am using 3.9.58.

在我的代码中），或者是由于REST和GET请求的性质而设计的？

So, is this a bug (in ServiceStack or in my code), or is this by design because of the nature of REST and GET request ?

推荐答案

为此，它终止请求：

httpResponse.EndServiceStackRequest();

这也是不推荐使用的，如果你想短接请求并阻止未来的处理，你应该使用：

Which is also deprecated, If you want to short-circuit the request and prevent future processing you should use:

httpResponse.EndRequest();

但在这种情况下，你只是想添加一个头，你不想这样做。

But in this situation you just want to add a header, you don't want to do this.
