elasticsearch简单操作(一)
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
1、增加记录
例如1:向指定的 /Index/Type 发送 PUT 请求,就可以在 Index 里面新增一条记录。比如,向/accounts/person发送请求,就可以新增一条人员记录。
curl -X POST 'localhost:9200/accounts/person/2' -d '{"user":"张三","title": "工程师","desc":"系统管理"}'系统提示如下错误:
{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}
需要制定插入数据格式:如下
curl -H "Content-Type: application/json" -X POST 'localhost:9200/accounts/person/2' -d '{"user":"张三","title": "工程师","desc":"系统管理"}'系统提示:
{"_index":"accounts","_type":"person","_id":"2","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":0,"_primary_term":1}说明插入成功
例如2:
curl -H "Content-Type: application/json" -X PUT 'localhost:9200/accounts/person/4' -d '{"user":"李四","title": "软件工程师","desc":"系理集成"}'系统提示:
{"_index":"accounts","_type":"person","_id":"4","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":1,"_primary_term":1}说明插入成功。
可以使用PUT、POST插入数据,需要制定插入数据的数据格式,用 -H "Content-Type: application/json"制定为json格式。
2、数据查询
curl 'localhost:9200/accounts/person/4?pretty'系统返回:
{"_index" : "accounts","_type" : "person","_id" : "4","_version" : 1,"found" : true,"_source" : {"user" : "李四","title" : "软件工程师","desc" : "系理集成"} }说明查询成功。如果查询一个不存在id的记录,如命令:
curl 'localhost:9200/accounts/person/5?pretty'id等于5的person因为没有对应的记录,所以,系统返回:
{"_index" : "accounts","_type" : "person","_id" : "5","found" : false }
3、删除记录
删除记录就是发出 DELETE 请求。
