Question

这是在我的Web API上调用PUT方法 - 方法的第三行（我从ASP.NET MVC前端调用Web API）：

enter image description here

client.BaseAddress是http://localhost/CallCOPAPI/。

这是contactUri：

enter image description here

这是contactUri.PathAndQuery：

enter image description here

最后，这是我的405回复：

enter image description here

这是我的Web API项目中的WebApi.config：

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

            config.Routes.MapHttpRoute(
                name: "DefaultApiGet",
                routeTemplate: "api/{controller}/{action}/{regionId}",
                defaults: new { action = "Get" },
                constraints: new { httpMethod = new HttpMethodConstraint("GET") });

            var json = config.Formatters.JsonFormatter;
            json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
            config.Formatters.Remove(config.Formatters.XmlFormatter);

我已经尝试剥离传递到PutAsJsonAsync到string.Format("/api/department/{0}", department.Id)和string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)但没有运气的路径。

有没有人知道我为什么会收到405错误？

根据请求，这是我的部门控制器代码（我将发布我的前端项目的部门控制器代码，以及WebAPI的部门ApiController代码）：

Answer 1

所以，我检查了Windows功能，以确保我没有安装这个名为WebDAV的东西，它说我没有。无论如何，我继续将我的web.config（前端和WebAPI，以确保）放在下面，它现在可以正常工作了。我把它放在<system.webServer>内。

<modules runAllManagedModulesForAllRequests="true">
    <remove name="WebDAVModule"/> <!-- add this -->
</modules>

此外，通常需要将以下内容添加到处理程序中的web.config。感谢Babak

<handlers>
    <remove name="WebDAV" />
    ...
</handlers>

Answer 2

WebDav-SchmebDav .. ..确保您正确创建了ID的网址。请勿像http://www.fluff.com/api/Fluff?id=MyID一样发送，请像http://www.fluff.com/api/Fluff/MyID一样发送。

例如

PUT http://www.fluff.com/api/Fluff/123 HTTP/1.1
Host: www.fluff.com
Content-Length: 11

{"Data":"1"}

这让我的小球永远破灭，完全尴尬。

Answer 3

将此添加到您的web.config。您需要告诉IIS PUT PATCH DELETE和OPTIONS的含义。以及IHttpHandler要调用的内容。

<configuation>
    <system.webServer>
    <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>
</configuration>

同时检查您是否启用了WebDAV。

Answer 4

我在IIS 8.5上运行ASP.NET MVC 5应用程序。我尝试了这里发布的所有变体，这就是我web.config的样子：

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        <remove name="WebDAVModule"/> <!-- add this -->
    </modules>  
    <handlers>      
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="WebDAV" />
      <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>

我无法从我的服务器上卸载WebDav，因为我没有管理员权限。此外，有时我在.css和.js文件上获得method not allowed。最后，通过上面的配置设置，一切都开始了。

Answer 5

用[FromBody]装饰一个动作参数解决了我的问题：

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    first_number, second_number, result = add(3,4)
TypeError: 'int' object is not iterable

但是，如果在方法参数中使用了复杂对象，ASP.NET会正确推断它：

public async Task<IHttpActionResult> SetAmountOnEntry(string id, [FromBody]int amount)

Answer 6

另一个原因可能是您没有使用＆＃34; id＆＃34;的默认变量名称。实际上是：id。

Answer 7

您的客户端应用程序和服务器应用程序必须位于同一个域下，例如：

客户端 - localhost

server - localhost

而不是：

客户端 - localhost：21234

server - localhost

Answer 8

在我的情况下，错误405由静态处理程序调用，因为路由（“api / images”）与同名文件夹（“〜/ images”）冲突。

Answer 9

您可以从GUI中手动删除特定于IIS的webdav模块。
1）转到II。
2）转到相应站点。
3）打开“处理程序映射”
4）向下滚动并选择WebDav模块。右键单击并将其删除。

注意：这还将更新您的Web应用程序的web.config。

Answer 10

这个简单的问题可能会引起头疼！

我可以看到您的控制器EDIT（PUT）方法需要两个参数：a）一个int id，以及b）一个部门对象。

当您从VS>使用具有读/写选项的添加控制器生成此代码时，它是默认代码。但是，您必须记住使用这两个参数来使用此服务，否则将出现错误405。

在我的情况下，我不需要PUT的id参数，因此我只是将它从标题中删除了……经过几个小时没有注意到它！如果将其保留在该位置，那么除非继续对配置进行必要的更改，否则名称也必须保留为id。
