我如何可以通过编程修改aspx文件内容之前处理程序处理呢？ [英] How can I programmatically modify an aspx file content before the handler handle it?

问题描述

我之所以需要修改一个aspx的内容（而不是身体，而是改在内存中的内容），因为有我做之前，整个ASPX被处理需要被解析到正确的数据一定的自定义标签在HttpHandler的。

The reason I need to modify the content of an aspx (not physically, but change the content in the memory) is because there are certain custom tags I made needs to be parsed to the correct data before the entire aspx is handled by the HttpHandler.

有没有一个办法？

推荐答案

您可以使用响应滤波器（HttpFilter）和修改内容的动态，响应基本形成后，过滤器被称为EndRequest之前（这是一个流后裔）并且你愿意，你可以修改它。在HTTP模块，你有init方法来安装HttpFilter（Response.Filter），它会调用该请求。

You can use Response Filters (HttpFilter) and modify content on the fly, basically after response is formed, before EndRequest your filter is called (it's a stream descendant) and you can modify it as you wish. In the HttpModule, Init method you got to install HttpFilter (Response.Filter) and it will be called for that request.
