ASP.NET Web API - 不允许PUT和DELETE动词 - IIS 8

Question

我最近从Visual Studio 2010升级到Visual Studio 2012 RC.安装程序还会安装IIS 8 Express,Visual Studio现在将其用作默认Web服务器.

IIS 8阻止了我使用PUT AND DELETE谓词的WEB API请求.IIS返回405错误,The requested resource does not support http method 'PUT'.

我知道过去人们对此有疑问,Stack Overflow上有几条关于它的消息.使用IIS 7 Express,解决方案是卸载WebDav.不幸的是,我没有看到任何与IIS 8相关的方法.

我已经尝试从applicationhost.config编辑出WebDav部分,但这没有帮助.例如,我<add name="WebDAVModule" image="%IIS_BIN%\webdav.dll" />从配置文件中删除了.

我花了很长时间才研究这个问题.必须有一种简单的方法来启用PUT和DELETE？

Answer 1

好的.我终于到底了.你需要跳过一些箍来让PUT和DELETE动词与IIS8一起正常工作.实际上,如果您安装VS 2012的候选版本并创建一个新的WEB API项目,您会发现示例PUT和DELETE方法会立即返回404错误.

要将PUT和DELETE谓词与Web API一起使用,您需要编辑%userprofile%\ documents\iisexpress\config\applicationhost.config并将动词添加到ExtensionlessUrl处理程序,如下所示:

改变这一行:

<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

至:

<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

除上述内容外,您还应确保WebDAV不会干扰您的请求.这可以通过注释applicationhost.config中的以下行来完成.

<add name="WebDAVModule" image="%IIS_BIN%\webdav.dll" />
<add name="WebDAVModule" /> 
<add name="WebDAV" path="*" verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" />

另请注意,默认Web API约定是您的方法名称应与调用的HTTP谓词相同.例如,如果您要发送HTTP删除请求,则默认情况下,您的方法应命名为"删除".

Answer 2

更改您的Web.Config文件,如下所示.它会像魅力一样.

在节点中<system.webServer>添加下面的代码部分

<modules runAllManagedModulesForAllRequests="true">
  <remove name="WebDAVModule"/>
</modules>

添加后,您的Web.Config将如下所示

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
        <remove name="WebDAVModule"/>
    </modules>
    <httpProtocol>
    <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
    </customHeaders>
    </httpProtocol>
    <handlers>
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>

Answer 3

删除WebDAV完全适合我的情况:

<modules>
  <remove name="WebDAVModule"/>
</modules>
<handlers>
  <remove name="WebDAV" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" 
       type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

通过web.config解决问题总是更好,而不是通过iis或machine.config修复它,如果应用程序托管在另一台机器上,它将不会发生

Answer 4

更新您的web.config

  <system.webServer>
    <modules>
      <remove name="WebDAVModule"/>
    </modules>
    <handlers>
      <remove name="WebDAV" />
      <remove name="ExtensionlessUrl-Integrated-4.0" />
      <add name="ExtensionlessUrl-Integrated-4.0"
           path="*."
           verb="GET,HEAD,POST,DEBUG,DELETE,PUT"
           type="System.Web.Handlers.TransferRequestHandler"
           preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
  </system.webServer>

无需修改主机配置.

Answer 5

在Asp.Net Web API中 - webconfig.这适用于所有浏览器.

在System.web标记内添加以下代码

<webServices>
  <protocols>
    <add name="HttpGet"/>
    <add name="HttpPost"/>
  </protocols>
</webServices>

用以下代码替换您的system.webserver标记

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
  </customHeaders>
</httpProtocol>
<modules runAllManagedModulesForAllRequests="false">
  <remove name="WebDAVModule" />
</modules>

<validation validateIntegratedModeConfiguration="false" />
<handlers>
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />

  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

</handlers>

Answer 6

启用 CORS（漂亮又整洁）

1.添加CORS nuget包

Install-Package microsoft.aspnet.webapi.cors

2.在WebApiConfig.cs文件中的Register方法中添加以下代码：

config.EnableCors();

例如：
使用 System.Web.Http；

namespace test
{
public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services


        config.EnableCors(); //add this**************************


        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );           
    }
}
}

3.将以下代码添加到控制器的命名空间中，包括 get、post、delete、put 或任何 http 方法

[EnableCors(origins: "The address from which the request comes", headers: "*", methods: "*")]

前任：

using System.Web.Http.Cors;//add this******************************
namespace Test.Controllers
{
[EnableCors(origins: "http://localhost:53681/HTML/Restaurant.html", headers: "*", methods: "*")]
public class RestaurantController : ApiController
{
    protected TestBusinessLayer DevTestBLL = new TestBusinessLayer();

    public List<Restaurant> GET()
    {
        return DevTestBLL.GetRestaurant();
    }

    public List<Restaurant> DELETE(int id)
    {
        return DevTestBLL.DeleteRestaurant(id);
    }       
}
}

Answer 7

这对iis8和其他一些答案都适用.我的错误是404.6具体

<system.webServer>
  <security>
  <requestFiltering>
    <verbs applyToWebDAV="false">
       <add verb="DELETE" allowed="true" />
    </verbs>
  </requestFiltering>
  </security>
</system.webServer>

Answer 8

只是对可能遇到此问题的任何其他人的快速更新.截至今天,更改%userprofile%\ documents\iisexpress\config\applicationhost.config不再起作用(这一直工作到现在,不确定这是否是由于Windows更新).经过数小时的挫折,我更改了web.config以将这些处理程序添加到system.webserver以使其工作:

<handlers>
        <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
        <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />

        <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
        <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>

Answer 9

对于 PHP，很简单：

1. 打开IIS
2. 转到处理程序映射
3. 单击 php5.6.x 或 php7.0.x 上的编辑
4. 点击“请求限制”
5. 在“动词”选项卡下，选择“以下动词之一”并添加“GET、HEAD、POST、PUT、PATCH、DELETE、OPTIONS”

我想这也适用于其他处理程序。
