我有来自后端的这种响应格式（URL为http://localhost:8080/App/api/currency）：

要使用Angular查询它我使用$resource's查询方法。但是这种响应结构不适用于$resource：

查询需要数组。这里我有单个对象
数组项被视为单个资源

如何使此回复与$resource一起使用，即指示它将content作为构建$resource对象的实际数据。或者有任何可靠的解决方案吗？

Answer 1

一种方法是明确使用<div class="content-section-b"> <div class="row"> <div class="col-lg-12">...：

$promise

当然，以这种方式使用return $resource(url).get().$promise.then(function(response){ return response.content; });时，$resource与$http没有太大区别，使用$resource优于$http的优势，就像直接使用{{1}}一样将结果绑定到范围，将丢失。

Hateoas和application / hal + json
