Permintaan Put API Web menghasilkan kesalahan Metode Http 405 Tidak Diizinkan

Inilah panggilan ke PUTmetode pada API Web saya - baris ketiga dalam metode (Saya memanggil API Web dari ujung depan ASP.NET MVC):

client.BaseAddressadalah http://localhost/CallCOPAPI/.

Inilah contactUri:

Inilah contactUri.PathAndQuery:

Dan akhirnya, inilah tanggapan 405 saya:

Inilah WebApi.config dalam proyek API Web saya:

        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);

Saya sudah mencoba melucuti menuruni jalan yang akan masuk ke PutAsJsonAsyncke string.Format("/api/department/{0}", department.Id)dan string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)tidak berhasil.

Adakah yang tahu mengapa saya mendapatkan error 405?

Jadi, saya memeriksa Fitur Windows untuk memastikan saya tidak memiliki hal yang disebut WebDAV diinstal, dan katanya saya tidak. Bagaimanapun, saya pergi ke depan dan menempatkan yang berikut di web.config saya (baik front end dan WebAPI, hanya untuk memastikan), dan itu berfungsi sekarang. Saya menempatkan ini di dalam <system.webServer>.

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

Selain itu, sering kali diperlukan untuk menambahkan yang berikut ke web.configdalam penangan. Terima kasih untuk Babak

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

WebDav-SchmebDav ... ..pastikan Anda membuat url dengan ID dengan benar. Jangan kirim seperti http://www.fluff.com/api/Fluff?id=MyID , kirimkan seperti http://www.fluff.com/api/Fluff/MyID .

Misalnya.

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

{"Data":"1"}

Ini membuatku kesal karena kekekalan kecil, benar-benar memalukan.

Tambahkan ini ke web.config. Anda perlu memberi tahu IIS apa PUT PATCH DELETEdan OPTIONSartinya. Dan yang IHttpHandlerharus dipanggil.

<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>

Periksa juga Anda tidak mengaktifkan WebDAV.

Saya menjalankan aplikasi ASP.NET MVC 5 di IIS 8.5. Saya mencoba semua variasi yang diposting di sini, dan inilah yang web.configterlihat seperti:

<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>

Saya tidak dapat menghapus WebDav dari Server saya karena saya tidak memiliki hak admin. Juga, kadang-kadang saya mendapatkan file method not allowed.css dan .js. Pada akhirnya, dengan konfigurasi di atas mengatur semuanya mulai berfungsi kembali.

Dekorasi salah satu aksi params dengan [FromBody] memecahkan masalah bagi saya:

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

Namun ASP.NET akan menyimpulkannya dengan benar jika objek kompleks digunakan dalam parameter metode:

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

Penyebab lain dari hal ini adalah jika Anda tidak menggunakan nama variabel default untuk "id" yang sebenarnya: id.

Dalam kasus saya kesalahan 405 dipanggil oleh pengendali statis karena rute ("api / gambar") yang bertentangan dengan folder dengan nama yang sama ("~ / gambar").

Anda dapat menghapus modul webdav secara manual dari GUI untuk khususnya di IIS.
1) Pergi ke IIs.
2) Mendapat situs masing-masing.
3) Buka "Pemetaan Handler"
4) Gulir ke bawah dan pilih modul WebDav. Klik kanan padanya dan hapus.

Catatan: ini juga akan memperbarui web.config Anda dari aplikasi web.

Aplikasi klien dan aplikasi server Anda harus di bawah domain yang sama, misalnya:

client - localhost

server - localhost

dan tidak :

client - localhost: 21234

server - localhost
