1、使用postman请求数据

http://localhost:9200/megacorp/employee/_search

2、出现以下错误

{
    "error": {
        "root_cause": [
            {
                "type": "parsing_exception",
                "reason": "Unknown key for a VALUE_STRING in [first_name].",
                "line": 2,
                "col": 23
            }
        ],
        "type": "parsing_exception",
        "reason": "Unknown key for a VALUE_STRING in [first_name].",
        "line": 2,
        "col": 23
    },
    "status": 400
}

3、原因：因为我的请求body里包含了数据

{
        "first_name": "John",
        "last_name": "Smith",
        "age": 27,
        "about": "I love to go rock climbing",
        "interests": [
            "sports",
            "music"
        ]
}

4、删除body数据重新请求，结果如下

    "took": 5,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 2,
        "max_score": 1.0,
        "hits": [
            {
                "_index": "megacorp",
                "_type": "employee",
                "_id": "2",
                "_score": 1.0,
                "_source": {
                    "first_name": "Jane",
                    "last_name": "Smith",
                    "age": 32,
                    "about": "I like to collect rock albums",
                    "interests": [
                        "music"
                    ]
                }
            },
            {
                "_index": "megacorp",
                "_type": "employee",
                "_id": "1",
                "_score": 1.0,
                "_source": {
                    "first_name": "John",
                    "last_name": "Smith",
                    "age": 27,
                    "about": "I love to go rock climbing",
                    "interests": [
                        "sports",
                        "music"
                    ]
                }
            }
        ]
    }
}
