Angularjs $ resource保存操作返回promise对象而不是响应的实际值

我将此工厂定义为调用rest方法:

(function() {
    'use strict';
    angular.module('rgh').factory('Charge', Charge);

    function Charge($resource) {
        return $resource('rgh/charge/charge', {}, {
            'save' : {
                url : 'rgh/charge/charge',
                method : 'POST'
            }
        });
    }
})();

RestContrller

@RestController
@RequestMapping("/rgh/charge/charge")
public class ChargeResource {

    @Autowired
    private IChargeService chargeService;

    @PostMapping
    public long save(@RequestBody ChargeViewModel viewModelEntity) {
        return chargeService.save(ModelMapper.map(viewModelEntity, Charge.class));
    }
}

你可以看到save方法返回已保存对象的id,现在我想在角度控制器中得到这个返回的id:

(function() {
    'use strict';

    angular
        .module('rgh')
        .controller('ChargeDetailController', ChargeDetailController);

    function ChargeDetailController(Charge) {
        var vm = this;
        vm.save = save;

        function save() {
            vm.isSaving = true;
            Charge.save(vm.charge, onSaveSuccess, onSaveError);
        }

        var onSaveSuccess = function (result) {
            vm.isSaving = false;

            console.log(result);
        };

        var onSaveError = function () {
            vm.isSaving = false;
        };
    }
})();

但是当我检查控制台时,我看到$promise对象而不是实际ID。

您可以按如下方式更改Angular Controller中的save方法:

function save() {

    vm.isSaving = true;

    Charge.save(vm.charge).$promise
        .then(function (result) {
            console.log(result);
        })
        .catch(function (error) {
            // Error
        })
        .finally(function() {
            vm.isSaving = false;
        });
}
