在使用elaticsearch8.13.0使用批量创建索引时，根据谷粒中说的es7.9方法去批量操作请求：

http://127.0.0.1:9200/shop/_doc/_bulk

注意1：设置header为Content-Type:application/x-ndjson,否则请求报错：

{
    "error": "Content-Type header [] is not supported",
    "status": 406
}

body:

{"index": {"_index":"shop","_type":"_doc","_id": "2004"}} 
{"id": "2004", "nickname": "index2004"} 
{"index": {"_index":"shop","_type":"_doc","_id": "2007"}} 
{"id": "2007", "nickname": "name2007"} 
{"index": {"_index":"shop","_type":"_doc","_id": "2008"}} 
{"id": "2008", "nickname": "name2008"}

报错信息如下：

{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "Malformed content, found extra data after parsing: START_OBJECT"
            }
        ],
        "type": "illegal_argument_exception",
        "reason": "Malformed content, found extra data after parsing: START_OBJECT"
    },
    "status": 400
}

根据报错翻译：内容格式错误，解析后发现额外数据：START_OBJECT。其实说白了就是请求的url不对。大家可以参考elaticsearch官网查看：

Bulk API | Elasticsearch Guide [8.14] | Elastic

注意2：body里面的Json或text最后要多空一行,如下截图：

否则会报错：

{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "The bulk request must be terminated by a newline [\\n]"
            }
        ],
        "type": "illegal_argument_exception",
        "reason": "The bulk request must be terminated by a newline [\\n]"
    },
    "status": 400
}

当你把上面的2个注意项设置后，请求成功界面如下：
