elasticsearch - 无法在 Elasticsearch 中创建映射和添加数据

Question

每次我按照有关在 elasticsearch 中创建索引、映射和添加数据的说明进行操作时，都会出现错误。
我正在使用 postman 。
首先，我创建索引:

POST http://localhost:9200/schools

(实际上，我必须使用 put 才能成功创建)

接下来，我创建映射并添加数据:

POST http://localhost:9200/schools/_bulk

请求正文

    {
       "index":{
          "_index":"schools", "_type":"school", "_id":"1"
       }
    }
    {
       "name":"Central School", "description":"CBSE Affiliation", "street":"Nagan",
       "city":"paprola", "state":"HP", "zip":"176115", "location":[31.8955385, 76.8380405],
       "fees":2000, "tags":["Senior Secondary", "beautiful campus"], "rating":"3.5"
    }
    {
       "index":{
          "_index":"schools", "_type":"school", "_id":"2"
       }
    }
    {
       "name":"Saint Paul School", "description":"ICSE 
       Afiliation", "street":"Dawarka", "city":"Delhi", "state":"Delhi", "zip":"110075",
       "location":[28.5733056, 77.0122136], "fees":5000,
       "tags":["Good Faculty", "Great Sports"], "rating":"4.5"
    }
    {
       "index":{"_index":"schools", "_type":"school", "_id":"3"}
    }
    {
       "name":"Crescent School", "description":"State Board Affiliation", "street":"Tonk Road", 
       "city":"Jaipur", "state":"RJ", "zip":"176114","location":[26.8535922, 75.7923988],
       "fees":2500, "tags":["Well equipped labs"], "rating":"4.5"
    }

但我收到的只是:

   {
      "error": {
        "root_cause": [
          {
            "type": "json_e_o_f_exception",
            "reason": "Unexpected end-of-input: expected close marker for Object (start marker at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@681c6189; line: 1, column: 1])\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@681c6189; line: 2, column: 3]"
          }
        ],
        "type": "json_e_o_f_exception",
        "reason": "Unexpected end-of-input: expected close marker for Object (start marker at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@681c6189; line: 1, column: 1])\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@681c6189; line: 2, column: 3]"
      },
      "status": 500
    }

这是因为您的请求正文 JSON 格式错误。我建议只检查一个条目，直到您可以将其输入 Elasticsearch，然后添加其他条目。

以下 JSON 是有效的，但我不确定它是否提供了您想要的结构:

{
   "index":{
      "_index":"schools", "_type":"school", "_id":"1"
   },
   "name":"Central School", "description":"CBSE Affiliation", "street":"Nagan",
   "city":"paprola", "state":"HP", "zip":"176115", "location":[31.8955385, 76.8380405],
   "fees":2000, "tags":["Senior Secondary", "beautiful campus"], "rating":"3.5"
}

您可以使用用于格式化和验证 JSON 的工具来确保它是有效的 JSON。下面是一些例子。
