Question

我正在使用Web Api Asp。网并想用javascript运行我的控制器：

JS

 function cargarCatalogo() {
            apiService.get("../../api/CatalogoRegistro/get/", null,
                function (res) {
                    $scope.Catalogos = res.data.Nombre; 
                },
                errorCatalogo);
        }

控制器

[AllowAnonymous]
    [HttpGet]
    [Route("{catalogo}")]
    public HttpResponseMessage Get(HttpRequestMessage request, string catalogo)
    {
        return CreateHttpResponse(request, () =>
        {
            HttpResponseMessage response = null;                
            var cr = _pService.Listar(param => param.Catalogos.Nombre.Equals(catalogo));
            IEnumerable<CatalogoRegistroViewModel> crs = Mapper.Map<IEnumerable<CatalogoRegistro>, IEnumerable<CatalogoRegistroViewModel>>(cr);
            var version = request.Headers.GetValues("Version").FirstOrDefault();// ServerVariables.Get("HTTP_X_MY_CUSTOM_HEADER_NAME");
            List<string> errores = new List<string>();

            if(cr==null)
            {
                errores.Add("El Catalogo no existe" );
                //response = request.CreateResponse<string>(HttpStatusCode.BadRequest, "El parametro no existe");                 
            }
            if(errores.Count>0)
                response = request.CreateResponse(HttpStatusCode.BadRequest, new { success = false, errores });
            else 
            {
                response = request.CreateResponse<IEnumerable<CatalogoRegistroViewModel>>(HttpStatusCode.OK, crs);   
            }

            return response;
        });
    }

但是我遇到了问题

获取http://localhost:55720/api/CatalogoRegistro/get/ 404（未找到）

我的api路线到底是什么？我不明白

Answer 1

您尝试使用[RoutePrefix("api/Catalogo")]致电api/CatalogoRegistro/get。我不确定您打算将哪些内容作为参数传递，但您希望采用/api/Catalogo/{catalogo}格式的内容，其中{catalogo}是GET的适当值打电话。

Answer 2

[RoutePrefix("api/Catalogo")]基本上说网址应为api/Catalogo而不是api/CatalogoRegistro。

function cargarCatalogo() {
   apiService.get("../../api/Catalogo", null,
   function (res) {
      $scope.Catalogos = res.data.Nombre; 
   },
   errorCatalogo);
}

如果你想从Angular传递catalogo到Web API，我相信你需要使用第二个参数 -

function cargarCatalogo() {
   apiService.get("../../api/Catalogo", catalogo,
   function (res) {
      $scope.Catalogos = res.data.Nombre; 
   },
   errorCatalogo);
}

Answer 3

试试这个：

在您的WebApi

中

[Route("api/CatalogoRegistro/get/{catalogo}")]

来自JS

 function cargarCatalogo() {
        var catalogoValue = "somevalueHere";
        apiService.get("/api/CatalogoRegistro/get/" + catalogoValue, null,
            function (res) {
                $scope.Catalogos = res.data.Nombre; 
            },
            errorCatalogo);
    }

用javascript调用get方法
