Question

我有一个AngularJS 1.0.7 webapp。在我的service.js中，我有一个SearcherService服务尝试同步调用CurrencyService服务，但有些东西无法正常工作。

.factory('SearcherService', function(CurrencyService, LocationService) {
    return {
        var currency = LocationService.getCurrency(); 
        if (currency == undefined) {
            var currency = CurrencyService.getCurrency();
            // do more thing after currency is got
        }
    };
})
.factory('CurrencyService', function(LocationService, Currency) {
    return {
        getCurrency: function() {
            Currency.query(function success(result) {
                var currencies = result;
                LocationService.setCurrency(currency[0]);                       
                return currency[0];         
            });
        }
    };
});

更新实际上没有错误堆栈跟踪。但我的预期行为是在继续执行//执行更多操作之前从CurrencyService.getCurrency获取货币值。我不知道为什么我有其他服务调用不会继续，直到服务方法调用完全执行但我没有看到差异。另请参阅我的货币服务。我想做这样的事情。但这不起作用。它永远不会进入回调函数。

var currency = LocationService.getCurrency(); 
if (currency == undefined) {
    CurrencyService.getCurrency().then(function(result) {
        currency = result;
        // do more thigs
    });                                                         
}

另见我的货币服务：

.factory('Currency', 

      function($resource, SERVER_URL){          
        var currencies =
         $resource('http://' + SERVER_URL +'/:action', {action:'currencies'}, {       
            query: {method:'GET', isArray: true},
            getConversionRate: {method:'GET', params:{action:'getConversionRate'}, isArray: false}
         });        
         return currencies;           
      }
  )

AngularJS 1.0.7服务同步调用
