Question

我定义了一个Restangular服务：

var dashboards = angular.module('models.dashboards', ['restangular']);

dashboards.factory('Dashboards', function(Restangular) {
    var Dashboards = Restangular.service('dashboards');
    Restangular.extendModel('dashboards', function (model) {
        //model.newMethod = function() {
        //}
    });
    return Dashboards;
});

在一个解决方案中，我想调用一个POST，然后在POST响应的Location头中返回的URL上调用GET。 POST不需要任何参数。

resolve: {
    'drafts': ['Dashboards', function (Dashboards) {
        return Dashboards.post().then(function(result) {
            return Dashboards.oneUrl('newDash', result.data).get();
        });
    }]
},

我配置了一个响应提取器，将位置标头设置为POST请求的响应数据。

RestangularProvider.setFullResponse(true);

RestangularProvider.setResponseExtractor(function(data, operation, route, url, response, deferred) {
    var returnData = data;

    if(operation === 'post') {
        console.log(response.headers());
        returnData = response.headers().location;
    }

    return returnData;
});

我可以看到POST请求，它返回201并带有正确的Location头。但我没有看到GET请求。相反，我得到了这个例外：

 TypeError: Cannot set property 'singleOne' of undefined

    at XMLHttpRequest.requestLoaded (ionic.bundle.js:17570)

创建服务时我犯了一个错误。我忘了在扩展它时返回model对象：

var dashboards = angular.module('models.dashboards', ['restangular']);

dashboards.factory('Dashboards', function(Restangular) {
    var Dashboards = Restangular.service('dashboards');
    Restangular.extendModel('dashboards', function (model) {
        //model.newMethod = function() {
        //}
        return model;
    });
    return Dashboards;
});
