json - 如何使用Elasticsearch将映射放入json文件

Question

我有很多具有以下结构的JSON文档:

"positions": [
    {
      "millis": 12959023,
      "lat": 49.01525113731623,
      "lon": 2.4971945118159056,
      "rawX": -3754,
      "rawY": 605,
      "rawVx": 0,
      "rawVy": 0,
      "speed": 9.801029291617944,
      "accel": 0.09442740907572084,
      "grounded": true
    },
    {
      "millis": 12959914,
      "lat": 49.01536940596998,
      "lon": 2.4967825412750244,
      "rawX": -3784,
      "rawY": 619,
      "rawVx": -15,
      "rawVy": 7,
      "speed": 10.841861737855924,
      "accel": -0.09534648619563282,
      "grounded": true
    }
...
}

我正在尝试通过引入geo_point字段来使用Elasticsearch映射此JSON文档，以获取类似于以下文档的文档:

"positions": [
        {
          "millis": 12959023,
          "location" : {
              "lat": 49.01525113731623,
              "lon": 2.4971945118159056,
           }          
          "rawX": -3754,
          "rawY": 605,
          "rawVx": 0,
          "rawVy": 0,
          "speed": 9.801029291617944,
          "accel": 0.09442740907572084,
          "grounded": true
        },
    ...
    }

PS:这些文档由API提供。

谢谢

您可以执行以下操作:

curl -XPUT 'http://localhost:9200/<indexname>/positions/_mapping' -d @yourjsonfile.json

希望这个 SO有帮助!
