标签:plugins signed 命令 状态 搜索 number sig start count 被 标记的部件含义: PROTOCOL HOST PORT PATH QUERY_STRING BODY 往本地ES中写入一条数据,索引名称为"test_log-2018-10-24",类型名称为"test_log": 从本地ES中获取一条数据,索引名称为"test_log-2018-10-24",类型名称为"test_log",id名称为"AWalLVzvZ_iZW0h4u8UH": 删除刚才插入的数据: 注意:删除数据,不但针对单条数据,还可以使用通配符删除整个type乃至整个索引 局部更新 全文搜索 querystring语法(上例中,?q=后面写的就是querystring语法): 获取集群健康状态 获取节点状态 获取主节点状态 显示集群的详细信息 查看主节点 查看所有索引 查看单节点健康状态 查看分片信息 查看插件信息 Elasticsearch涉及的RESTful API 标签:plugins signed 命令 状态 搜索 number sig start count 原文地址:http://blog.51cto.com/fengjicheng/2348019一、格式
curl -X
VERB
适当的 HTTP 方法 或 谓词 : GET、 POST、 PUT、 HEAD 或者 DELETE。
http 或者 https(如果你在 Elasticsearch 前面有一个 https 代理)
Elasticsearch 集群中任意节点的主机名,或者用 localhost 代表本地机器上的节点。
运行 Elasticsearch HTTP 服务的端口号,默认是 9200 。
API 的终端路径(例如 _count 将返回集群中文档数量)。Path 可能包含多个组件,例如:_cluster/stats 和 _nodes/stats/jvm 。
任意可选的查询字符串参数 (例如 ?pretty 将格式化地输出 JSON 返回值,使其更容易阅读)
一个 JSON 格式的请求体 (如果请求需要的话)二、API类型
1.数据写入(POST)
curl -XPOST http://127.0.0.1:9200/test_log-2018-10-24/test_log -d ‘{
"date":"1540369436",
"user":"test",
"mesg":"this is a test message"
}‘
#返回:
{"_index":"test_log-2018-10-24","_type":"test_log","_id":"AWalLVzvZ_iZW0h4u8UH","_version":1,"result":"created","_shards":{"total":1,"successful":1,"failed":0},"created":true}
2.数据获取(GET)
curl -XGET http://127.0.0.1:9200/test_log-2018-10-24/test_log/AWalLVzvZ_iZW0h4u8UH
#返回
{"_index":"test_log-2018-10-24","_type":"test_log","_id":"AWalLVzvZ_iZW0h4u8UH","_version":1, "found":true,"_source":{
"date":"1540369436",
"user":"test",
"mesg":"this is a test message"
}}
3.数据删除(DELETE)
curl -XDELETE http://127.0.0.1:9200/test_log-2018-10-24/test_log/AWalLVzvZ_iZW0h4u8UH
#返回
{"found":true,"_index":"test_log-2018-10-24","_type":"test_log","_id":"AWalLVzvZ_iZW0h4u8UH","_version":2,"result":"deleted","_shards":{"total":1,"successful":1,"failed":0}}
例如:curl -XDELETE ‘http://127.0.0.1:9200/*-${DATA}‘
三、常用API
1._update
curl -XPOST ‘http://127.0.0.1:9200/test_log-2018-10-24/test_log/AWalXZ4cZ_iZW0h4vlQj/_update‘ -d ‘{
"doc":{
"user":"fjc"
}
}‘
#返回
{"_index":"test_log-2018-10-24","_type":"test_log","_id":"AWalXZ4cZ_iZW0h4vlQj","_version":2,"result":"updated","_shards":{"total":1,"successful":1,"failed":0}}
2._search
curl -XGET http://127.0.0.1:9200/test_log-2018-10-24/test_log/_search?q=test
curl -XGET http://127.0.0.1:9200/test_log-2018-10-24/test_log/_search?q=mesg:test
全文检索:直接写搜索的单词,例如加上例中的test
单字段的全文检索:在搜索单词前加上字段名和冒号,比如,如果知道单词test肯定出现在mesg字段,可以写作mesg:test
单字段的精确检索:在搜索单词前后加上双引号,比如user:"fjc"
多个检索条件的组合:可以使用NOT、AND和OR来组合检索,注意必须是大写
字段是否存在:exists:user表示要求user字段存在,missing:user表示要求user字段不存在
通配符:用?表示单字母,*表示任意个字母
近似搜索:用~表示搜索单词可能有一两个字母写得不对,请Elasticsearch按照相似度返回结果。比如test~
范围搜索:对数值和时间,Elasticsearch都可以使用范围搜索,比如:rtt>300、date:["now-6h" TO "now"}等。其中,[]表示端点数值包含在范围内,{}表示端点数值不包含在范围内3._cluster
