Json 字符串的 JsonPath 表达式？

问题描述

我有以下 JSON 字符串。我需要一些帮助来编写一个 Jayway JsonPath 表达式来获取特定角色的受让人，比如“编辑”：

{
  "assignments": [
    {
      "role": {
        "label": "Editor","id": "8bc3e27aafe310001fc933216b890910"
      },"assignees": [
        {
          "label": "user 1","id": "bd76276f5e5344e4b27f8600c9000726"
        },{
          "label": "user 2","id": "abbb210550af1017329208ee8632618c"
        }
      ]
    },{
      "role": {
        "label": "Owner","id": "8bc3e27aafe310001fc932f0d928090f"
      },"assignees": [
        {
          "label": "user 3","id": "3db5d9e1081e470bb98d5a3d15b67180"
        },{
          "label": "user 4","id": "586e403c186c01521f763b5d4d0e6000"
        }
      ]
    },{
      "role": {
        "label": "Viewer","id": "8bc3e27aafe310001fc9333ecccf0911"
      },"assignees": [
        {
          "label": "user 5","id": "9bdfa0b60668100b619f393cfc282340"
        },{
          "label": "user 6","id": "586e403c186c018f6c8d798c4e0e6a00"
        }
      ]
    }
  ]
}
