Question

下面是我从后端生成的json数据

{"langs":[{"cisAreaId":100,"area":"Prog","name":"C#"},{"cisAreaId":110,"area":"Prog","name":"Java"},{"cisAreaId":120,"area":"Prog","name":"MS.NET languages(VB.NET,etc)"},{"cisAreaId":130,"area":"Prog","name":"MS Visual Languages (VB, C++, etc)"},{"cisAreaId":140,"area":"Prog","name":"Python"},{"cisAreaId":150,"area":"Prog","name":"Ruby"}]}

以上数据我复制到$ scope.areas。现在在我看来

<div ng-repeat="lang in areas.langs">
        <label><input type="checkbox" ng-model="lang.selected" value="{{lang.cisAreaId}}" /> {{lang.name}}</label>
    </div>

用户点击提交后，我需要捕获所选的复选框值并将其作为JSON数据发送。

    $scope.languageArray = [];
    angular.forEach($scope.areas.langs, function (lang) {
        if (lang.selected) $scope.languageArray.push({ "cisAreaId": lang.cisAreaId });
    });
    var data = JSON.stringify({
        languages: $scope.languageArray,
    });

在选择两个复选框值

之后形成数组

{"languages":[{"cisAreaId":110},{"cisAreaId":120}]}

从上面的代码中我如何在URL中传递上述动态数组来调用后端方法

Angularjs Controller Code:    
XXXService.step2Form(data).then(function (results) {
            console.log(results.data); 
        }, function (error) {
            alert(error.data.message);
        });

service code:
var _step2Form = function (data) {
       return $http.post(serviceBase + 'api/feedback/Step2Data' + data , { headers: { 'Content-Type': 'application/json' } });
        };

我已将数据动态传递到后端

public HttpResponseMessage Step2Data([FromBody] int[] languages)

但是我收到了这样的错误

http://localhost:53401/api/XXXX/Step2Data[object%20Object],[object%20Object] 404 (Not Found)

任何人都可以告诉我如何在url中动态传递数组值来调用webapi方法。

在$scope.languageArray中

你只需要推送id：

$scope.languageArray = [];
angular.forEach($scope.areas.langs, function (lang) {
   if (lang.selected) $scope.languageArray.push(lang.cisAreaId);
});
var data = JSON.stringify({
     languages: $scope.languageArray,
});

在URL中动态传递Array数据以调用webapi方法（C＃）
