Question

我已经在这几个小时了。你如何过滤工作？在线解决方案都没有。

我想要做的就是从名称“Tori Smith”的json中获取评论（由这些＆lt;＆lt;＆lt;＆lt;＆gt;＆gt;＆gt;＆gt;突出显示）。我一直在使用这个应用来测试http://jsonpath.curiousconcept.com/。 这就是我所得到的：'comments.data。 .from.id'

数据：

Answer 1

要获得评论，您需要引入一个过滤表达式，以便过滤到＃34; Tori Smith＆＃34;然后选择注释字段。

一步一步地获取所有评论，你需要这个：

$.comments.data

然后过滤到只有＆＃34; Tori Smith＆＃34;添加如下过滤器：

$.comments.data[?(@.from.name == 'Tori Smith')]

最后，要仅选择消息，请按以下方式展开查询：

$.comments.data[?(@.from.name == 'Tori Smith')].message

我在这里使用在线JSON查询工具对此进行了测试： http://www.jsonquerytool.com/sample/jsonpathwhereselectcomments
