blocks|key|1670446|text|您可以使用fiddler作为客户端和服务器之间的代理。这意味着您可以启动fiddler，然后使用fiddler的端口而不是通常的端口(我认为fiddler2的默认端口是8888+)访问服务器。如果需要调试服务器“实时”与真实客户端，可以将IIS绑定从:80更改为其他绑定，并将fiddler的代理放在端口80上。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1670447|编辑:顺便说一下，默认情况下，fiddler2会更改浏览器上的代理设置，这样浏览器就可以通过fiddler访问所有内容(仅在安装了fiddler的机器上)|1670448|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can use fiddler as a proxy between your clients and the server. This means you start up fiddler, and then access the server using fiddler's port rather then the usual port (default for fiddler2 is 8888 I think). If you need to debug the server "live" vs. real world clients, you can change the IIS binding from :80 to something else, and place fiddler's proxy on port 80.

EDIT: By the way, by default fiddler2 changes the proxy settings on your browsers so that they access everything through fiddler anyway (on the machine in which fiddler is installed only)

This has nothing to do with IIS7 Express and everything to do with the fact that you're using loopback traffic.

Ref: <a href="https://www.fiddlerbook.com/fiddler/help/hookup.asp#Q-LocalTraffic" rel="noreferrer">https://www.fiddlerbook.com/fiddler/help/hookup.asp#Q-LocalTraffic</a>

Click Rules > Customize Rules.

Update your Rules file like so:

<pre><code>static function OnBeforeRequest(oSession:Fiddler.Session)
{
 if (oSession.HostnameIs("MYAPP")) { oSession.host = "localhost:portnumber"; }
}
</code></pre>

Then, just visit <code>http://myapp</code> in your browser.

Or use the address <code>http://localhost.fiddler/</code> and Fiddler will use the hostname <code>localhost</code> instead of converting to an IP address.

blocks|key|636747|text|Eric的答案(由Brett编辑)的一个有用的变体是使用oSession.port来构建oSession.host。通过这个小小的改变，如果需要捕获http://localhost:12345上的IIS+express流量，他们可以使用http://iisexpress:12345。这将使捕获WebMatrix和VS创建的具有随机端口的站点的流量变得更容易。我在IE和Firefox上试用过，捕获IIS+Express流量轻而易举。小提琴手太棒了！|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|636748|static+function+OnBeforeRequest(oSession:Fiddler.Session)

One useful variation of Eric's answer (that was edited by Brett) would be to use <code>oSession.port</code> to build the <code>oSession.host</code>. With this little change, if one needs to capture IIS express traffic on <code>http://localhost:12345</code>, they could use <code>http://iisexpress:12345</code>. That will make it easier to capture traffic for sites with random ports as created by WebMatrix and VS. I tried it out with IE and Firefox and capturing IIS Express traffic was a breeze. Fiddler rocks!.

<pre><code>static function OnBeforeRequest(oSession:Fiddler.Session)
{
 //...
 // workaround the iisexpress limitation
 // URL http://iisexpress:port can be used for capturing IIS Express traffic
 if (oSession.HostnameIs("iisexpress")) { oSession.host = "localhost:"+oSession.port; }
 //...
}
</code></pre>

With the latest version of fiddler, you only need to navigate to localhost.fiddler:port. However, doing that alone didn't help me and I was still getting access denied when using Windows Authentication. To fix this, I found this blog entry: <a href="http://www.parago.de/2013/01/fiddler-and-the-401-unauthorized-error-with-asp-net-web-api-using-integrated-windows-authentication-wia/" rel="nofollow">http://www.parago.de/2013/01/fiddler-and-the-401-unauthorized-error-with-asp-net-web-api-using-integrated-windows-authentication-wia/</a>

In short, create this key:

Key Path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Lsa\MSV1_0

Value Name BackConnectionHostNames

Value Type REG_MULTI_SZ 

String Value localhost.fiddler

I am using IIS7 Express while developing my web application. I need to use fiddler to investigate an issue and cannot figure out how to configure things so I can get the HTTP stream. It seems that IIS7 express will only listen on localhost which means I cannot access the stream.

在开发我的web应用程序时，我正在使用IIS7 Express。我需要使用fiddler来调查一个问题，但我不知道如何配置才能获得HTTP流。IIS7 express似乎只在本地主机上侦听，这意味着我不能访问流。
