StrongLoop / LoopBack:在Rest连接器数据源模板上获取完整的jSON

时间:2015-06-23 04:30:23

标签: node.js loopbackjs strongloop

我正在尝试从Google地理编码API获取完整的jSON响应,以便我可以测试结果“状态”。

来自文档:

  

responsePath:应用于HTTP正文的可选JSONPath。看到   https://github.com/s3u/JSONPath了解JSON路径的语法。

所以我使用了“responsePath”:“$ .. *”但它得到的反应都搞砸了。

示例:

好的,现在好像很清楚。 '搞砸了' response是应用JSONPath表达式的结果,其结果是数组,而不是JSON对象。您可以在此处查看一些示例:https://github.com/s3u/JSONPath/blob/master/test/test.examples.js

因此,如果您只需要状态,则可以使用此过滤器:"responsePath": "$.status"。否则,您可以完全删除responsePath并获取原始JSON对象。
