StrongLoop / LoopBack：在其他连接器数据源模板上获得完整的jSON
我试图从谷歌地理编码API得到完整的json响应，所以我可以testing结果“状态”。
从文档：
responsePath：应用于HTTP正文的可选JSONPath。 有关JSONpath的语法，请参阅https://github.com/s3u/JSONPath 。
所以我使用“responsePath”：“$ .. *”，但它得到的响应都搞砸了。
例：

所以，如果你只需要状态，你可以使用这个filter： "responsePath": "$.status" 。 否则，您可以完全删除responsePath并获取原始的JSON对象。
