如何更改输入请求流 [英] How can I change the Input request stream

问题描述

详细信息是:

我想将输入流中的文本1"替换为文本2"

第一个:我将Request.Filter用作 http://msdn.microsoft. com/en-us/library/system.web.httprequest.filter.aspx 但是这种方式我只能将一个字节数据替换为另一个字节，不能将字符串替换为字符串，也不能更改缓冲区大小.我需要使用其他字节数组(content和buffer.length)访问并替换旧缓冲区.

第二个:我尝试使用ISAPI筛选器，但是似乎IIS 7及更高版本不再支持SF_NOTIFY_READ_RAW_DATA.我谷歌，结果是我应该写一个本地的HttpModule与CHttpModule :: OnReadEntity事件.是吗?

如果您能告诉我如何更改输入请求流，将不胜感激.

非常感谢.

Detail is:

I want to replace the ''Text 1'' in the Input stream to ''Text 2''

The first: I use the Request.Filter as http://msdn.microsoft.com/en-us/library/system.web.httprequest.filter.aspx But this way I can only replace a byte data by an other byte, I can not replace a string by a string and I also can not change buffer size. I need to access and replace the old buffer by an other byte array (content and buffer.length)

The second: I try to use a ISAPI Filter, but It seem that the IIS 7 and above is no longer support for SF_NOTIFY_READ_RAW_DATA. I google and result is I should write a native HttpModule with CHttpModule::OnReadEntity event. Is it right ?

I would be very appreciate if you can tell me how I can change the input request stream.

Thank you very much.
