ElasticSearch RESTFUL API的簡單操作

1、查看狀態

GET /_cat/health?v

2、查詢索引全部數據

GET /ma_2020/_search

3、查詢索引mapping

GET /ma_2020/_mapping

4、刪除索引

DELETE /ma_2020

5、創建索引

PUT /ma_2020

6、設置mapping

PUT /qhpms_retail_headpremium/_mapping
{
      "properties" : {
        "@timestamp" : {
          "type" : "date"
        },
        "@version" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "agent_name" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "agent_no" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "c_crt_tm" : {
          "type" : "date"
        },
        "dep" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "dept_code" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "dept_name" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "insurance_preminum" : {
          "type" : "float"     #類型爲long時，kibana小數點後面可能會被省略
        },
        "policy_create_time" : {
         "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "type" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        }
      }
    }

7、時間範圍查詢

GET /ma_2020/_search
{
  "query": {
    "range": {
      "@timestamp": {
          "from": "2020-05-14T06:29:29.000Z",
          "to": "2020-05-18T01:20:29.000Z"
      }
    }
  }
}

8、查詢並刪除數據

GET /ma_2020/_delete_by_query
{
  "query": {
    "range": {
      "@timestamp": {
          "from": "2020-05-14T06:29:29.000Z",
          "to": "2020-05-18T01:20:29.000Z"
      }
    }
  }
}

9、導入一條數據

POST /pcis_work_dayly/_doc/123456789(唯一ID)
{
      "dep_name": "廣東分公司",
      "name": "車險",
      "network": "互聯網",
      "dayly_premium": 5,
	  "c_crt_tm": "2020-03-25",
	  "month_premium": 40,
	  "dayly_premium_icome": 5.03,
	  "year_premium_icome": 400,
	  "year_premium": 300,
	  "year_target": 2500,
	  "time_progress_task": 20.15
}
