第一章第五节：Elasticsearch之新增一个文档

1、PUT请求

1:PUT请求必须要带上指定的id
2:PUT请求 如果不存在则创建，存在（_id存在）则更新
3:如果是更新 响应回来的数据 _version和result会有变化

PUT /customer/external/1
{
  "name":"张三",
  "cname":"zhangsan",
  "age":22,
  "birthday":"2020-09-22",
  "address":"北京市朝阳区立汤路"
}

响应结果：

{
  "_index" : "customer",
  "_type" : "external",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

2、POST请求

1:POST请求可以指定id，也可以不指定id（会生成一个随机_id）
2:POST请求 如果不存在则创建，存在（_id存在）则更新
3:如果是更新 响应回来的数据 _version和result会有变化

{
  "name":"李四",
  "cname":"lisi",
  "age":25,
  "birthday":"2020-09-22",
  "address":"北京市朝阳区立汤路"
}
