REST 服務錯誤 405：方法不允許

Question

我的 Get 工作正常，但我的更新和刪除給了我 405 錯誤。 這是我的 Web.config 和控制器。 抱歉格式不正確。 我嘗試了很多不同的方法，但我不確定為什么會出現 405 錯誤。 我的應用程序與我的其他 REST 服務一起使用，所以我知道它可以執行 CRUD，並且問題是我的服務。

這是我的控制器

public class ResponseItemsController : BaseApiController
{
    static readonly IwellService wellService = new wellService(new 
    wellRepository());

    [HttpGet]
    [BasicAuthentication(RequireSsl = false)]
    public HttpResponseMessage Get()
    {
        return base.BuildSuccessResult(HttpStatusCode.OK, 
        wellService.GetData());
    }

    [HttpPost]
    [BasicAuthentication(RequireSsl = false)]
    public HttpResponseMessage Create([FromBody]ResponseItem item)
    {
        try
        {
            if (item == null ||
                string.IsNullOrWhiteSpace(item.Name__c) ||
                string.IsNullOrWhiteSpace(item.Question_1__c))
            {
                return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.wellItemNameAndNotesRequired.ToString());
            }

            // Determine if the ID already exists
            var itemExists = wellService.DoesItemExist(item.ID);
            if (itemExists)
            {
                return base.BuildErrorResult(HttpStatusCode.Conflict, ErrorCode.wellItemIDInUse.ToString());
            }
            wellService.InsertData(item);
        }
        catch (Exception)
        {
            return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.CouldNotCreateItem.ToString());
        }

        return base.BuildSuccessResult(HttpStatusCode.Created);
    }

    [HttpPut]
    [BasicAuthentication(RequireSsl = false)]
    public HttpResponseMessage Edit(string id, [FromBody]ResponseItem item)
    {
        try
        {
            if (item == null ||
                string.IsNullOrWhiteSpace(item.Name__c) ||
                string.IsNullOrWhiteSpace(item.Mentor_name__c))
            {
                return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.wellItemNameAndNotesRequired.ToString());
            }

            var wellItem = wellService.Find(id);
            if (wellItem != null)
            {
                wellService.UpdateData(item);
            }
            else
            {
                return base.BuildErrorResult(HttpStatusCode.NotFound, ErrorCode.RecordNotFound.ToString());
            }
        }
        catch (Exception)
        {
            return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.CouldNotUpdateItem.ToString());
        }

        return base.BuildSuccessResult(HttpStatusCode.NoContent);
    }

    [HttpDelete]
    [BasicAuthentication(RequireSsl = false)]
    public HttpResponseMessage Delete(string id)
    {
        try
        {
            var wellItem = wellService.Find(id);
            if (wellItem != null)
            {
                wellService.DeleteData(id);
            }
            else
            {
                return base.BuildErrorResult(HttpStatusCode.NotFound, ErrorCode.RecordNotFound.ToString());
            }
        }
        catch (Exception)
        {
            return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.CouldNotDeleteItem.ToString());
        }

        return base.BuildSuccessResult(HttpStatusCode.NoContent);
    }
}

}

這是我的路由 WebApiconfig/Routeconfig。 我試過使用 [Route("api/responseitems/")] 作為控制器，然后使用 [Route("api/responseitems/{id}")] 作為方法，但同樣的 405 錯誤問題。 我寫的異常代碼只有 404,400,200。

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
        // Web API routes
        config.MapHttpAttributeRoutes();

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


public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new {id = UrlParameter.Optional }
        );
        }
    }

我認為問題在於您的應用程序的調用機制。 您可以在調用 API 時使用正確的 Http 動詞嗎？

或者將您的完整端點與您的方法類型放在一起，以便我可以進一步幫助您。
