IIS返回500，当节点的应用程序返回4XX [英] IIS returns 500 when Node app returns a 4xx
问题描述
我也问过这个在 iisnode GitHub的项目
我通过Windows Azure的网站使用IISNode。
I am using IISNode via a Windows Azure Website.
如果我的节点的应用程序返回2xx状态code（200，201等），那么一切都很好，按预期工作。
If my Node app returns a 2xx status code (200, 201, etc), then all is well and works as expected.
如果我的节点的应用程序返回4xx状态code，例如： response.send（404，未找到）（我用的RESTify）然后我得到发送到客户端500和简直是无法显示身体页因为发生内部服务器错误。
if my Node app returns a 4xx status code, for example:
response.send(404, "not found") (I am using Restify) then I get a 500 sent to the client and the body is simply "The page cannot be displayed because an internal server error has occurred."
如果我蔚蓝的网站日志结尾＆LT;网站名称方式＆gt; ，那么当500被发送到客户端，日志中包含一个404的HTML
If I do azure site log tail <sitename>, then when the 500 gets sent to the client, the log contains HTML of a 404.
...
<body>
<div id="content">
<div class="content-container">
<h3>HTTP Error 404.0 - Not Found</h3>
<h4>The resource you are looking for has been removed, had its name changed,
or is temporarily unavailable.</h4>
</div>
...
我真的只是想IISNode / IIS把我的404，并将其发送下来到客户端。这也是401S，409s，等真正的他们都导致500获得送吧。
I really just want IISNode/IIS to take my 404 and send it on down to the client. This is also true of 401s, 409s, etc. They all cause a 500 to get sent instead.
我曾尝试＆LT;的customErrors模式=关/＆GT; 和＆LT; httpErrors existingResponse =直通/＆GT; 在我的web.config无济于事。这是我现在的web.config：
I have tried <customErrors mode="off" /> and <httpErrors existingResponse="passThrough" /> in my web.config to no avail. Here is my web.config now:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<customErrors mode="off" />
</system.web>
<system.webServer>
<httpErrors existingResponse="PassThrough" />
<staticContent>
<mimeMap fileExtension=".svg" mimeType="image/svg+xml" />
<mimeMap fileExtension=".ico" mimeType="image/x-icon" />
</staticContent>
<handlers>
<add name="iisnode" path="server.js" verb="*" modules="iisnode"/>
</handlers>
<rewrite>
<rules>
<rule name="DynamicContent">
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
</conditions>
<action type="Rewrite" url="server.js"/>
<match url="/*" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
有关它的价值，我不能让IISnode做任何事情，但是从我的节点应用程序返回200S。试图让IIS服务于我的静态文件，使节点检查，或者任何其他的更有趣IISNode功能造成500我。不知道为什么，很想得到过去吧！
For what it's worth, I can't get IISnode to do anything but return 200s from my node app. Trying to get IIS to serve my static files, enable node-inspector, or really any of the more interesting IISNode features cause a 500 for me. No idea why, and would love to get past it!
<一个href=\"http://stackoverflow.com/questions/15144405/windows-azure-websites-is-overriding-my-404-and-500-error-pages-in-my-node-js-ap\">this问题是pretty多的究竟的我的问题。除＆LT; httpErrors existingResponse =直通/＆GT; 不为我工作。我觉得我有一些更根本性的错误我IISNode的设置，因此，如果任何人有任何的事情的想法去尝试，我所有的耳朵。
this question is pretty much exactly my problem. Except that <httpErrors existingResponse="PassThrough" /> does not work for me. I feel like I have something more fundamentally wrong with my IISNode setup, so if anyone has any ideas on things to try I'm all ears.
推荐答案
由于某种原因，在你的配置以下部分导致此问题：
for some reason the following section in your config is causing this issue:
<staticContent>
<mimeMap fileExtension=".svg" mimeType="image/svg+xml" />
<mimeMap fileExtension=".ico" mimeType="image/x-icon" />
</staticContent>
作为解决办法，如果可能的话除去这部分，然后重试。我将调查为什么这部分导致了此问题。
As a workaround, remove this section if possible and retry. I will investigate why this section is causing this issue.
