elasticsearch 的post put 方式的对比 setting mapping设置

Posted 2020-11-30 littlevigra

1.POST和PUT都可以用于创建

2.PUT是幂等方法，POST不是。所以post用户更新，put用于新增比较合适。

----------------------------------------------------------------------------------------------------------------------

1.post

curl -XPOST http://192.168.1.49:9200/test/user/1  \\
  -H \'cache-control: no-cache\' \\
  -H \'content-type: application/json\'  -d \'{"name" : "john" }\'            ==>指定id
----------------------------------------------------

curl -XPOST http://192.168.1.49:9200/test/user/11 \\
-H \'cache-control: no-cache\' \\
-H \'content-type: application/json\'  -d \'{"name" : "john" }\'

非幂等性，可以用来修改记录
----------------------------------------------------
 curl -XPOST http://192.168.1.49:9200/test/user  \\
  -H \'cache-control: no-cache\' \\
  -H \'content-type: application/json\'  -d \'{"name" : "john"}\'
不指定id，自动生成

2.put

curl -XPUT http://192.168.1.49:9200/test/user/22/_create    -H \'cache-control: no-cache\'   -H \'content-type: application/json{"name" : "john" }\' 指定id
------------------------------------------------------幂等性，不能重复操作
curl -XPUT http://192.168.1.49:9200/test/user/22/_create    -H \'cache-control: no-cache\'   -H \'content-type: application/json{"name" : "john222" }\'
version conflict, document already exists
