角資源與HATEOAS和應用/ HAL + JSON

Question

予有這種響應格式從後端（URL是http://localhost:8080/App/api/currency）：

要使用角查詢它我使用$resource's查詢方法。但是，此響應結構不適用於$resource：

• 查詢需要數組。在這裏，我有一個對象
• 陣列項目作爲單一資源

我怎樣才能使與$resource即此響應工作指導其採取content作爲構建$resource對象的實際數據處理。還是有任何強大的解決方案呢？

Answer 1

一種方法是使用$promise明確：

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

當然，使用$resource當這種方式，有沒有與$http太大的區別，並且使用$resource超過$http，如直接結合的結果的優點範圍，都丟失了。
