c# - used - La API de Web Put Request genera un error Http 405 Method Not Allowed

method not allowed java

Question

Aquí está la llamada al método PUT en mi API web: la tercera línea del método (estoy llamando a la API web desde una interfaz de usuario ASP.NET MVC):

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

Aquí está el contactUri :

Aquí está contactUri.PathAndQuery :

Y finalmente, esta es mi respuesta 405:

Aquí está el WebApi.config en mi proyecto de API web:

        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);

He intentado desglosar la ruta que pasa en PutAsJsonAsync a string.Format("/api/department/{0}", department.Id) y string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id) sin suerte.

¿Alguien tiene alguna idea de por qué estoy recibiendo el error 405?

ACTUALIZAR

Según solicitud, este es el código de mi controlador de departamento (publicaré tanto el código de controlador del departamento para mi proyecto de interfaz, como el código de ApiController del Departamento para WebAPI):

Answer 1

Agregue esto a su web.config . Necesita decirle a IIS qué significa PUT PATCH DELETE y OPTIONS . Y que IHttpHandler para invocar.

<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>

También compruebe que no tiene WebDAV habilitado.

Answer 2

Decorar uno de los params de acción con [FromBody] resolvió el problema para mí:

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

Sin embargo, ASP.NET lo inferiría correctamente si se utilizara un objeto complejo en el parámetro del método:

public async Task<IHttpActionResult> UpdateEntry(string id, MyEntry entry)

Answer 3

En mi caso, el controlador 405 invocó el error 405 debido a la ruta ("api / images") en conflicto con la carpeta del mismo nombre ("~ / images").

Answer 4

Entonces, revisé las características de Windows para asegurarme de que no tenía instalada esta cosa, llamada WebDAV, y dije que no. De todos modos, seguí y coloqué lo siguiente en mi web.config (tanto en el front end como en WebAPI, solo para estar seguro), y funciona ahora. <system.webServer> esto dentro de <system.webServer> .

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

Además, a menudo se requiere agregar lo siguiente a web.config en los controladores. Gracias a Babak

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

Answer 5

Estoy ejecutando una aplicación ASP.NET MVC 5 en IIS 8.5. Probé todas las variaciones publicadas aquí, y así es como se ve mi web.config :

<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>

No pude desinstalar WebDav de mi servidor porque no tenía privilegios de administrador. Además, a veces obtenía el method not allowed en los archivos .css y .js. Al final, con la configuración anterior configurada, todo comenzó a funcionar nuevamente.

Answer 6

La aplicación del cliente y la aplicación del servidor deben estar bajo el mismo dominio, por ejemplo:

cliente - localhost

servidor - localhost

y no :

cliente - localhost: 21234

servidor - localhost

Answer 7

Otra causa de esto podría ser si no usa el nombre de variable predeterminado para el "id" que en realidad es: id.

Answer 8

WebDav-SchmebDav ... asegúrese de crear correctamente la URL con la ID. No lo envíe como http://www.fluff.com/api/Fluff?id=MyID , envíelo como http://www.fluff.com/api/Fluff/MyID .

P.ej.

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

{"Data":"1"}

Esto estaba revienta mis bolas por una pequeña eternidad, total vergüenza.
