Question

我希望你能帮助我。我想把头发拉出来！

我正在尝试使用Id作为传递参数进行API调用以查找特定记录。

这样的事情：$http.get("/api/vendor/ReadVendor/" + vendorId)

需要做什么：

当我选择供应商时，使用唯一的供应商ID进行API调用。这将传递给Controller和DTO以及DB，并返回指定的数据。

我收到错误：

404 / Not Found {＆＃34; Message＆＃34;：＆＃34;未找到与请求URI匹配的HTTP资源＆＃39; http://localhost:60090/api/vendor/ReadVendor/5＆＃39; 。＆＃34;，＆＃34; MessageDetail＆＃34;：＆＃34;未在控制器＆＃39;供应商＆＃39;上找到任何操作。与请求匹配。＆＃34; }

我的堆栈流程是这样的：

adminVendorNumber.html
adminVendorNumber.controller.js
VendorController.cs
VendorDTO.cs

以下是用于调用AngularJS函数的adminVendorNumber.html的一部分：

                        <label>Vendor</label>
                        <div class="input-dropdown">
                            <cc-dropdown cc-placeholder="Select Vendor"
                                         ng-model="NewVendorNumber.Vendor"
                                         ng-disabled="false"
                                         ng-options="vendorData"
                                         cc-fields="VendorId"
                                         cc-key-field="VendorId"
                                         cc-allow-search="false"
                                         ng-required="false"
                                         ng-change="vendorSelected()"
                                         name="iVendor">
                            </cc-dropdown>
                        </div>
                    </div>

这是我的AngularJS控制器（具有我特定功能的部分）：

(function () {
    "use strict";

    angular
        .module('app.adminVendorNumber')
        .controller('adminVendorNumberController', adminVendorNumberController);

    adminVendorNumberController.$inject = ['$http', 'logger', '$scope'];

    function adminVendorNumberController($http, logger, $scope) {
        var vm = $scope;
        vm.formSubmmision = true;

        vm.vendorItemData = null;
        vm.itemGroupData = null;
        vm.vendorData = null;

        vm.vendorSelected = vendorSelected;

        vm.save = save;

        activate();

        function activate() {
            return vendorItemData().then(getAllItemGroups).then(getVendorData).then(function () {
                logger.info('Activated Vendor Number Creation');
            });
        }


        function vendorSelected() {

            vm.formSubmmision = true;
            return getVendorById(vm.NewVendorNumber.Vendor.VendorId);
        }

        function getVendorById(vendorId) {
            return $http.get("/api/vendor/ReadVendor/" + vendorId)
                .then(Success)
                .catch(Failure);

            function Success(responce) {
                vm.vendorSelected = responce.data.Records;
                return vm.vendorSelected;
            }

            function Failure(error) {
                logger.error('Failed to get Vendor Data ' + error.data.Message);
            }
        }

    };
}
)();

以下是我的VendorController.cs函数的一部分：

    public class VendorController : ApiController
    {
        private VendorDTO dto = new VendorDTO();

        public HttpResponseMessage ReadVendor(int vendorId)
        {
            try
            {
                CommandResult<Vendor> result = dto.ReadVendor(vendorId);
                return Request.CreateResponse((result.Status == CommandStatus.Success ? HttpStatusCode.OK : HttpStatusCode.InternalServerError), result);
            }
            catch (IOWAException ex)
            {
                return Request.CreateResponse(HttpStatusCode.InternalServerError, ex.Message);
            }
        }

    }
}

以下是调用VedorDTO.cs的下一步：

public class VendorDTO
{

    public CommandResult<Vendor> ReadVendor(int vendorId)
    {
        return readVendor(vendorId);
    }

    private CommandResult<Vendor> readVendor(int vendorId)
    {
        CommandResult<Vendor> result = null;

        try
        {
            VendorContext dalVendor = new VendorContext();
            result = dalVendor.Read(vendorId);
        }
        catch (IOWAException ex)
        {
            result = new CommandResult<Vendor>(ex, "Error reading Vendors");
        }

        return result;
    }

Answer 1

如下所述，在动作上指定[HttpGet]属性：

[HttpGet]
public HttpResponseMessage ReadVendor(int vendorId)

Answer 2

请使用 GetReadVendor

更改您的方法名称

或

在方法上方添加HttpGet，如下所示：

# Using mlply to run the function, and find the closest coordinates with progress bar library(plyr) postcode[mlply(cbind(x1, y1), .fun = algo, .progress = "tk")]

Answer 3

[HttpGet]
 public CommandResult<Vendor> ReadVendor(int vendorId)
{
    return readVendor(vendorId);
}

还有一件事试试这个获得的陈述

         $http.get('Your URL/?vendorId='+your val)

Answer 4

您的API控制器似乎存在一些问题。您必须在控制器中定义HTTP方法和路由以使其工作。此外，您需要将vendorId更改为id。

[RoutePrefix("api/vendor")]
public class VendorController : ApiController
{
    [Route("ReadVendor"), HttpGet]
    public HttpResponseMessage ReadVendor(int? id)
    {
        return Request.CreateResponse(HttpStatusCode.OK, "");
    }
    //Rest of your code
}

AngularJS API调用ID为param和C＃Contoller
