在 ASP.NET & 中记录原始和压缩的 HTTP 响应IIS7 [英] Logging raw and compressed HTTP responses in ASP.NET & IIS7

问题描述

按照这个问题 我想创建一个 HttpModule 来为我们记录一些自定义的请求和响应.使用该问题最流行的答案中的代码，我已经启动并运行了一个确实有效的 HttpModule:

Along the lines of this question I want to create a HttpModule that will do some custom logging of requests and responses for us. Using the code in the most popular answer for that question I've got a HttpModule up and running which does indeed work:

class PortalTrafficModule : IHttpModule
{
    public void Dispose()
    {
        // Do Nothing
    }

    public void Init(HttpApplication context)
    {
        context.BeginRequest += new EventHandler(context_BeginRequest);
        context.EndRequest += new EventHandler(context_EndRequest);
    }

    private void context_BeginRequest(object sender, EventArgs e)
    {
        HttpContext context = ((HttpApplication)sender).Context;

        // Create and attach the OutputFilterStream to the Response and store it for later retrieval.
        OutputFilterStream filter = new OutputFilterStream(context.Response.Filter);
        context.Response.Filter = filter;
        context.Items.Add("OutputFilter", filter);

        // TODO: If required the request headers and content could be recorded here
    }

    private void context_EndRequest(object sender, EventArgs e)
    {
        HttpContext context = ((HttpApplication)sender).Context;
        OutputFilterStream filter = context.Items["OutputFilter"] as OutputFilterStream;

        if (filter != null)
        {
            // TODO: Log here - for now just debug.
            Debug.WriteLine("{0},{1},{2}",
                context.Response.Status,
                context.Request.Path,
                filter.ReadStream().Length);
        }
    }
}

(注意代码中引用的OutputFilterStream类在引用的问题).

但是，响应似乎缺少我在 Fiddler 中看到的一些 HTTP 标头(例如日期")，更重要的是，当我打开压缩时，我正在记录的响应没有被压缩，而我在 Fiddler 中看到的是.

However, the responses seem to be missing some HTTP headers that I see in Fiddler (like "Date") and more importantly, when I turn on compression the responses I'm logging aren't compressed whereas what I see in Fiddler is.

所以我的问题 - 是否可以记录压缩内容，或者这是否发生在我的模块无法连接的后续步骤中?

So my question - is it possible to log the compressed content or is this happening in a subsequent step my module can't hook in to?

作为记录，我也尝试过处理 PreSendRequestContent 事件，但响应仍未压缩.

For the record, I've also tried handling the PreSendRequestContent event and the response is still uncompressed.

推荐答案

您好，虽然我无法直接回答您的问题，但我过去曾做过类似的事情，并且发现以下资源非常有帮助和启发.最后，通过在 web config 中配置 System.Diagnostics 节点并创建流量跟踪日志，我设法实现了我需要的原始 soap 标头.我了解您的需求可能比这更细化，但我相信此资源可能仍有帮助.

Hi although I cannot answer your questions directly I have had cause to do similar things in the past and have found the following resource extremely helpful and enlightening. In the end I managed to acheive what I needed for raw soap headers by configuring the System.Diagnostics node within web config and create a trace log of traffic. I understand that your needs may be more granular than that however I believe this resource may still help.

特别感兴趣的可能是上面的消息日志配置和查看消息日志链接.

Of particular interest may be the message log configuration and viewing message logs links from the one above.
