Question

我想在拦截器完成基本消息处理后使用$ promise.then（successCallback，errorCallback）。如果我收到错误400,401等信息，它总是以某种方式一直运行到successCallback中，而不会运行到errorCallback中。如果我删除了拦截器，它就可以正常工作。我还发现，我可以在拦截器中创建新的承诺来解决此问题，但我认为这不是最好的方法。在我的情况下，我只想要一个用于某些基本消息处理的拦截器，然后在主控制器中继续使用主逻辑。目前这是不可能的，因为如果遇到错误，我总是会碰到successCallback。我了解错了吗？这是我想要的示例：

var resourceObj = $resource("url/abc/:action/:id", {}, {
    getMember: {
        method: 'GET',
        params: { action: 'member' },
        interceptor: {
            responseError: function(response) {
                console.log("Interceptor responseError");
                //Show some default error messages here
                return response; //create new promise with $http(response); to solve the problem? 
            },
            response: function(response) {
                console.log("Interceptor responseSuccess");
                //Show some default success messages here
                return response; //create new promise with $http(response); to solve the problem? 
            }
        }
    }
});
myModule.controller('myCtrl', function($scope) {
    $scope.checkMember() = function(memberId) {
        resourceObj.getMember({ id: memberId }, {}).$promise.then(
            function(responseOK) { //successCallback
                console.log(responseOK);
                $scope.testMember = responseOK.data; // or if no interceptor is used responseOK.toJSON()
                //do some stuff here after async call is finished               
            },
            function(responseError) { //errorCallback, never called in error case if an interceptor is used. 
                console.log(responseError);
                //do maybe some advanced error handling here after async call is finished
            }
        );
    }
});

重新抛出错误响应很重要。

var resourceObj = $resource("url/abc/:action/:id", {}, {
    getMember: {
        method: 'GET',
        params: { action: 'member' },
        interceptor: {
            responseError: function(response) {
                console.log("Interceptor responseError");
                //Show some default error messages here
                ̶r̶e̶t̶u̶r̶n̶ ̶r̶e̶s̶p̶o̶n̶s̶e̶;̶
                //IMPORTANT re-throw error response
                throw response;
            },
            response: function(response) {
                console.log("Interceptor responseSuccess");
                //Show some default success messages here
                return response;
            }
        }
    }
});

如果仅返回错误响应，则会错误地将其转换为，从拒绝到成功。

在拦截器之后错误地使用$ promise.then（）调用successCallback
