post请求
post请求不带id,会自动生成id
POST st_test_2021_01_25/_doc
{
"user" : "zhangsan",
"post_data" : "2021-01-25",
"message" : "zhangsan try to create"
}
post请求在文档上增加字段,不会先删除后创建,是在原来的document上增加
POST st_test_2021_01_25/_doc/1/_update
{
"doc":{
"age" : 12
}
}
执行结果,会发现这里的user、post_data、message等属性没有发生变化,属性值保留
{
"_index" : "st_test_2021_01_25",
"_type" : "_doc",
"_id" : "1",
"_version" : 4,
"_seq_no" : 4,
"_primary_term" : 1,
"found" : true,
"_source" : {
"user" : "st1",
"post_data" : "2021-01-25",
"message" : "st1 try to create",
"age" : 12
}
}
