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

【elasticsearch 的post put 方式的对比 setting mapping设置】 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" }\'
