如何获取/跟踪asp.net传出的响应文本 [英] how to get/trace asp.net outgoing response text

问题描述

我的服务器似乎有时返回错误的HTML Web客户

my server seems to be sometimes returning wrong html to webclients

使用asp.net 4在IIS上与前preSS VS 2012的调试IM。

im using asp.net 4 with VS 2012. debugging on IIS Express.

为了调试这个问题，我还想跟踪的ASP.NET是发送HTML

in order to debug this issue, id like to trace the html that asp.net is sending

在 Global_asax_ preRequestHandlerExecute 我可以访问响应code和地位，但不能似乎发现身体HTML

in the Global_asax_PreRequestHandlerExecute i can access the response code and status, but cant seem to find the body html

我想读的OutputStream 是这样的：

Dim ms = New MemoryStream
CurContext.Response.OutputStream.CopyTo(ms)
Dim sr = New StreamReader(ms)
Dim rtext = sr.ReadToEnd

但抛出一个引发NotSupportedException 流不支持读取。

什么想法？

非常感谢

修改

我现在测试这是肯定的。

i now tested this for sure

我在页面上的标签具有以下属性。

i have a label on the page with the following attributes

<asp:label id="l" runat="server" Font-Bold="true" Font-Size="X-Large" BackColor="Pink"/>

在浏览器中显示

当它显示就好了，如下：

when displayed in the browser it shows just fine, as follows:

<span id="C1_FormView1_l" style="background-color:Pink;font-size:X-Large;font-weight:bold;">Processed</span>

但与Web客户端下载，我得到

but when downloaded with webclient i get

<span id="C1_FormView1_l"><b><font size="6">Processed</font></b></span>

为什么是背景色失去了什么？和顺便说一句，为什么没有用更现代的风格属性，而不是加入 B 和字体

如果我能读ResponseStream我至少知道它在哪里丢失，甚至，我不知道现在。

if i could read the ResponseStream i would at least know WHERE it gets lost, even that i dont know now.

非常感谢你。

P.S。如果.NET 4.5是这更好的话，我可能会考虑更改目标框架

P.S. if .net 4.5 is better for this, then i might consider changing the target framework

推荐答案

这并没有回答我原来的问题在技术上，但它确实解决了我是有问题的。

this does not answer my original question technically, but it does solve the issue i was having

问题是，HTML渲染wasnt正确

the problem was that the html wasnt rendering correctly

我现在记得的aspx具有自适应渲染，所以我fgured请求中使用用户代理可能是罪魁祸首。

i now remembered that aspx has adaptive rendering, so i fgured the useragent used in the request might be to blame

我改变了我的code为：

i changed my code to:

 Dim myReq As HttpWebRequest = WebRequest.Create(MailUrl)
 myReq.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1"
 Dim resp As HttpWebResponse = myReq.GetResponse
 Dim stream = resp.GetResponseStream
 Dim rdr = New StreamReader(stream)
 Dim BodyText = rdr.ReadToEnd

和现在的HTML是正确的现代HTML5 / CSS3标记渲染

and now the html is rendering in correct modern Html5/Css3 markup

我AP preciate您的帮助和指导。
