如何将没有ID的批量插入发送到ElasticSearch

我正在尝试使用Bulk Inset API进行弹性搜索。我想插入带有自动生成ID的文档,但不管我怎么做,都会出错。

以下是一些例子:

http://localhost:9200/_bulk
{"create": {"_index": "test", "_type": "_doc"} }
{"user": "kimchy", "post_date": "2002-11-15T14:12:12", "message": "trying out Elasticsearch"}

Put和Post都给出了错误:

{
  "error": {
    "root_cause": [
      {
        "type": "action_request_validation_exception",
        "reason": "Validation Failed: 1: an id must be provided if version type or value are set;"
      }
    ],
    "type": "action_request_validation_exception",
    "reason": "Validation Failed: 1: an id must be provided if version type or value are set;"
  },
  "status": 400
}

如果我删除“类型”文档,我会得到以下错误:

{
  "error": {
    "root_cause": [
      {
        "type": "action_request_validation_exception",
        "reason": "Validation Failed: 1: type is missing;2: an id is required for a CREATE operation;3: an id must be provided if version type or value are set;"
      }
    ],
    "type": "action_request_validation_exception",
    "reason": "Validation Failed: 1: type is missing;2: an id is required for a CREATE operation;3: an id must be provided if version type or value are set;"
  },
  "status": 400
}    

我正在通过Docker使用弹性搜索6.4.2

~ docker images
REPOSITORY       TAG       IMAGE ID      CREATED      SIZE
elasticsearch    6.4.2     e47ebd7ec3ee  7 weeks ago  828MB

当前通过邮递员发送请求
