问题描述

我有一个Web API应用程序。它的工作原理，当我测试它使用VS 2010的调试开发服务器非常清楚。但我现在部署它IIS 7.5和我正在试图访问应用程序时，一个HTTP 404错误。

下面是我的web.config

解决方案

我这个苦苦挣扎也是如此。幸运的是，史蒂夫米凯洛蒂记载，为我工作的解决方案<一href=\"http://geekswithblogs.net/michelotti/archive/2011/05/28/resolve-404-in-iis-ex$p$pss-for-put-and-delete-verbs.aspx\">here.

在一天结束的时候，我所有启用的动词（动词=*）的ExtensionlessUrlHandler - 集成 - 4.0处理程序在我的web配置。

 ＆LT; system.webServer＆GT;
    ＆LT;验证validateIntegratedModeConfiguration =FALSE/＆GT;
    ＆LT;模块runAllManagedModulesForAllRequests =真/＆GT;
        ＆LT;＆处理GT;
            ＆LT;清除NAME =ExtensionlessUrlHandler  - 集成 -  4.0/＆GT;
            ＆LT;添加名称=ExtensionlessUrlHandler  - 集成 -  4.0PATH =*。动词=*TYPE =System.Web.Handlers.TransferRequestHandler= resourceType为未指定requireAccess =脚本preCondition =integratedMode，runtimeVersionv4.0/＆GT;
        ＆LT; /处理器＆GT;
＆LT; /system.webServer>
 

另一些人指出，有WebDAV的启用导致的问题。幸运的是，我没有碰到这个问题为好。

I have a Web Api application. It works perfectly well when I tested it using the VS 2010 debugging dev server. But I now deployed it to IIS 7.5 and I am getting a HTTP 404 error when trying to access the application.

Here is my web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-FlowGearProxy-20123141219;Integrated Security=True" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <appSettings>
    <add key="webpages:Version" value="2.0.0.0" />
    <add key="webpages:Enabled" value="true" />
    <add key="PreserveLoginUrl" value="true" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
    <authentication mode="Forms">
      <forms loginUrl="~/Account/Login" timeout="2880" />
    </authentication>
    <pages>
      <namespaces>
        <add namespace="System.Web.Helpers" />
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Routing" />
        <add namespace="System.Web.WebPages" />
      </namespaces>
    </pages>
  </system.web>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>
</configuration>

解决方案

I was struggling with this as well. Fortunately, Steve Michelotti documented a solution that worked for me here.

At the end of the day, I enabled all verbs (verb="*") to the ExtensionlessUrlHandler-Integrated-4.0 handler in my web config.

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true" />
        <handlers>
            <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
            <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
        </handlers>
</system.webServer>

Others have pointed out that having WebDAV enabled causes issues. Fortunately, I did not run into that issue as well.
