使用JMESPath转换JSON：Visual Studio Code插件指南

在Visual Studio Code中，JSON-Transform插件为您提供了一种高效的方式来处理和转换JSON数据。利用JMESPath，您可以对选定的JSON数据进行评估，并通过输出通道生成转换结果。

什么是JMESPath？

JMESPath是一种查询语言，专门用于从JSON文档中提取和转换数据。要进一步了解JMESPath，请查看JMESPath教程和JMESPath示例。

使用示例：

表达式：

locations[?state == 'WA'].name | sort(@) | {WashingtonCities: join(', ', @)}

示例JSON：

{
  "locations": [
    {"name": "Seattle", "state": "WA"},
    {"name": "New York", "state": "NY"},
    {"name": "Bellevue", "state": "WA"},
    {"name": "Olympia", "state": "WA"}
  ]
}

结果：

{
  "WashingtonCities": "Bellevue, Olympia, Seattle"
}

通过上述示例，您可以看到如何使用JMESPath表达式从JSON数据中筛选并排序华盛顿州的城市名，并将结果格式化为一个包含城市名称的对象。
