ES中使用restful api对数据进行增删查改

1）GET：查询数据2）POST：插入或更改数据 3）PUT：创建库或表 4）DELETE：删除库

Index:数据库type:表Document:行Field:列,字段Mapping:元信息

创建数据库:http://localhost:9200/sinamail/ PUT查看所有数据库:http://localhost:9200/_cat/indices/ GET删除数据库:http://localhost:9200/sinamail/ DELETE

旧版本创建表,并且定义字段:http://localhost:9200/sinamail/webmail/_mapping PUT插入数据:http://localhost:9200/sinamail/webmail/ POST{ "accessLog": "测试一下"}查询数据:http://localhost:9200/sinamail/_search POST{"query":{"bool":{"must":[{"match":{"accessLog":"测试下"}}]}},"from":0,"size":10}

使用CURL命令操作数据:curl http://127.0.0.1:9200 查看状态curl -XPUT http://127.0.0.1:9200/sinamail 创建数据库curl http://127.0.0.1:9200/_cat/indices/ 查看所有数据库创建表,并且定义字段

curl -XPUT http://127.0.0.1:9200/sinamail/webmail/_mapping -d '{

"webmail": {

"properties": {

"accessLog": {

"type": "string"

}

}

}

}'

插入数据

curl -XPOST http://127.0.0.1:9200/sinamail/webmail -d '{

"accessLog":"我是一个好人的测试"

}'

查询数据

curl -XPOST http://127.0.0.1:9200/sinamail/_search -d '{

"query":{
