Web API Put Request生成Http 405 Method Not Allowed错误

Question

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

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

这是contactUri:

这是contactUri.PathAndQuery:

最后,这是我的405回复:

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);

我试着剥离下来获取传递到路径PutAsJsonAsync,以string.Format("/api/department/{0}", department.Id)和string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)没有运气.

有没有人有任何想法为什么我得到405错误？

UPDATE

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,我继续把我的web.config(前端和WebAPI,以确保)放在下面,现在它可以工作了.我把它放在里面<system.webServer>.

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

此外,通常需要web.config在处理程序中添加以下内容.感谢Babak

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

Answer 2

WebDav-SchmebDav .. ..确保您正确创建了ID.不要把它像http://www.fluff.com/api/Fluff?id=MyID,把它像http://www.fluff.com/api/Fluff/MyID.

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.你需要告诉IIS什么PUT PATCH DELETE和OPTIONS意味着什么.IHttpHandler要调用哪个.

<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>

另请检查您是否未启用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化,这就是我的web.config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卸载WebDav,因为我没有管理员权限.此外,有时我得到了method not allowed.css和.js文件.最后,通过上面的配置设置,一切都开始了.

Answer 5

使用[FromBody]装饰其中一个动作参数解决了我的问题:

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

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> UpdateEntry(string id, MyEntry entry)
