使用 curl 將 geojson 數據索引到 elasticsearch

Question

我想使用 curl 將geojson數據索引到 elasticsearch

geojson 數據如下所示：

{
"type": "FeatureCollection",
"name": "telco_new_development",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [

但是，我的 curl 返回一個名為The bulk request must be terminated by a newline [\\n]的錯誤

curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/geo/building/_bulk?pretty' --data-binary @building.geojson

{
  "error" : {
    "root_cause" : [
      {
        "type" : "illegal_argument_exception",
        "reason" : "The bulk request must be terminated by a newline [\\n]"
      }
    ],
    "type" : "illegal_argument_exception",
    "reason" : "The bulk request must be terminated by a newline [\\n]"
  },
  "status" : 400
}

有什么建議嗎？

Answer 1

您的格式不適合這樣的_bulk ，因為它缺少預期的結構。 https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html進入那個

你需要;

• 將您的 json 文件更新為在每個文檔之前都有類似{ "index": { "_index": "INDEX-NAME-HERE" } }
• 每個文檔也需要在一行上
• 每行的末尾都需要一個\n以便批量 API 知道操作/記錄何時結束
