Question

我正在尝试使用JSONpath来查询我的JSON对象。逻辑||或者＆amp;＆amp;运营商在工作。但是，当我尝试对谓词进行分组时，请执行逻辑||或者＆amp;＆amp;操作似乎没有起作用。 Source

E.g。

$..[?(@.book=='fiction' && @.store=='online')]

E.g。

$..[?(@.store=='online' || @.store=='offline') && (@.NER=='observation')]

第二个不起作用。关于错误位置的任何指针或者尚不支持该功能

Answer 1

？应该涵盖所有条件。即整体圆形支架丢失。

正确路径：

$..[?((@.store=='online' || @.store=='offline') && (@.NER=='observation'))]

我已在http://jsonpath.com/

的不同示例中对其进行了验证

示例JSON：

{
  "store": {
    "book": [
      {
        "category": "fiction",
        "author": "Nigel Rees",
        "title": "Sayings of the Century",
        "price": 8.95
      },
      {
        "category": "fiction",
        "author": "Nigel Rees",
        "title": "Sword of Honour",
        "price": 12.99
      },
      {
        "category": "fiction",
        "author": "Herman Melville",
        "title": "Moby Dick",
        "isbn": "0-553-21311-3",
        "price": 8.99
      },
      {
        "category": "fiction",
        "author": "J. R. R. Tolkien",
        "title": "The Lord of the Rings",
        "isbn": "0-395-19395-8",
        "price": 22.99
      }
    ]
  }
}

具有多种条件的路径：

$..[?((@.category=='fiction' || @.author=='Nigel Rees') && (@.price < 10))]

结果：

'0' ...
  'category' => "fiction"
  'author' => "Nigel Rees"
  'title' => "Sayings of the Century"
  'price' => "8.95"
'1' ...
  'category' => "fiction"
  'author' => "Herman Melville"
  'title' => "Moby Dick"
  'isbn' => "0-553-21311-3"
  'price' => "8.99"
