GET /_cat/nodes:查看所有节点 GET /_cat/health:查看es健康状况 GET /_cat/master:查看主节点 GET /_cat/indices:查看所有索引2.索引一个文档
PUT mytest/basic/1 //保存在mytest索引下的basic类型id为1号的数据
{
“name":"test"
}
返回信息
{
"_index": "mytest", //索引名称
"_type": "basic", //类型
"_id": "1", //id
"_version": 1, //版本
"result": "created", //操作
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 0,
"_primary_term": 1
}
POST不带id为新增操作，带了id则查看存在，则为修改，其他为新增。
put则必须带id，不然无法发送
3.查看文档GET mytest/basic/1 //查看在mytest索引下的basic类型id为1号的数据
返回结果
{
"_index": "mytest", //索引
"_type": "basic", //类型
"_id": "1", //记录id
"_version": 1, //版本号
"_seq_no": 0, //并发字段，更新+1。，可以做乐观锁
"_primary_term": 1, //主分片
"found": true,
"_source": { //内容
"name": "test"
}
}
4.更新文档
POST mytest/basic/1/_update //带来_update则会对比原来的数据，不相同版本才+，相同则不改变。且需要编写doc
{
"doc":{
"name":"mytest"
}
}
POST mytest/basic/1/ //不带update,则直接修改，版本+
{
"name":"mytest"
}
put和不带_update的post都会直接更新数据
5.删除文档DELETE mytest/basic/1 //删除mytest索引下的basic类型的1号数据 DELETE mytest删除一个索引6. bulk批量API
POST /mytest/basic/_bulk
{"index":{"_id":"1"}}
{"name":"test"}
{"index":{"_id":"2"}}
{ "name":"test2"}
返回结果
{
"took" : 12, //花费时间
"errors" : false, //没有错误
"items" : [0
{
"index" : { //第一个数据
"_index" : "mytest",
"_type" : "basic",

}
}
]
}
POST /_bulk
{ "delete": { "_index": "website", "_type": "blog", "_id": "123" }} //删除website索引下blog类型下的id为123的记录，后面的以之前的类推即可
