我正在处理一个具有基本 CRUD 操作的 ASP.NET WebAPI 项目。该项目在本地运行，并有一个位于 Windows Azure 中的示例数据库。

到目前为止，Http GET 和 POST 工作正常，给了我一个 200 和 201。但我正在努力处理 DELETE 和 POST。我更改了 Web.config 中的处理程序，删除了 WebDav，但这些都不起作用。此外，启用 CORS 和 [AcceptVerbs] 等各种属性也不起作用。

知道我做错了什么吗？

网络配置:

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
      <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" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
 </system.webServer>

Controller :

 public class ProductController : BaseApiController
    {
        public ProductController(IRepository<Product> repo)
            : base(repo)
        {

        }

        [HttpGet]
        public IEnumerable<Product> Get()
        {
            //...
        }

        [HttpGet]
        public Product Get(int id)
        {
            //...
        }

        [HttpPost]
        public HttpResponseMessage Post([FromBody] Product product)
        {
           //...
        }

        [HttpPut]
        public HttpResponseMessage Put(int productId, [FromBody] Product product)
        {
            //..
        }

        [HttpDelete]
        public HttpResponseMessage Delete(int productId)
        {
            //..
        }

    }

路由和格式化程序:

 public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));


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

        // Custom Formatters:
        config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(
            config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml"));

        var jsonFormatter = config.Formatters.OfType<JsonMediaTypeFormatter>().First();
        jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    }
}

最佳答案

我终于找到我搞砸的地方了。两个 Controller 方法(Post 和 Put)中 Id (productId) 的命名必须与自定义路由 (id) 中的命名相同。当我将它从 productId 更改为 id 时，POST 和 PUT 都在 fiddler 中工作。之后，我将我的 Web.config 设置切换回默认设置。这是我改变的:

Controller :

    [HttpPut]
    public HttpResponseMessage Put(int id, [FromBody] Product product)
    {
        //..
    }

    [HttpDelete]
    public HttpResponseMessage Delete(int id)
    {
        //..
    }

网络配置:

<system.webServer>
<modules>
  <remove name="FormsAuthentication" />
</modules>
<handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
