角资源与HATEOAS和应用/ HAL + JSON

Question

予有这种响应格式从后端（URL是http://localhost:8080/App/api/currency）：

要使用角查询它我使用$resource's查询方法。但是，此响应结构不适用于$resource：

• 查询需要数组。在这里，我有一个对象
• 阵列项目作为单一资源

我怎样才能使与$resource即此响应工作指导其采取content作为构建$resource对象的实际数据处理。还是有任何强大的解决方案呢？

Answer 1

一种方法是使用$promise明确：

return $resource(url).get().$promise.then(function(response){ 
    return response.content; 
}); 

当然，使用$resource当这种方式，有没有与$http太大的区别，并且使用$resource超过$http，如直接结合的结果的优点范围，都丢失了。
