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

每次我按照有关在elasticsearch中创建索引、映射和添加数据的说明操作时，我都会出错。 我用的是邮递员。 首先，我创建索引：

POST http://localhost:9200/schools

（实际上，我必须使用put成功创建）

接下来，我创建映射并添加数据：

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

请求主体

    {
       "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"
    }

但我得到的只是：

   {
      "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
    }

这是因为您的请求主体JSON格式不正确。我建议只使用一个条目进行检查，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"
}

您可以使用一个格式化和验证JSON的工具来确保它是有效的JSON。下面是一些例子

要将数据加载到Elasticsearch，请使用REST API端点“/\u bulk”，该端点需要 以下换行符分隔的JSON（NDJSON）结构：

action_and_meta_data\n
optional_source\n
....
action_and_meta_data\n
optional_source\n

卷曲请求示例： curl-H'Content Type:application/x-ndjson'-XPOST'elasticsearchhost:port/index name sample/_bulk？pretty'-data binary@sample.json

在您的情况下，请求如下： curl-H'内容类型：application/x-ndjson'-XPOST'localhost:9200/schools/_bulk？pretty'-data binary@schools-sample.json

schools-sample.json内容：

{"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"}
/n

重要信息：数据的最后一行必须以换行符结尾\n。每个换行符前面都可以有回车符\r\n。否则，您将得到一个错误：

{
  "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
}

这是错误的。大容量插入api不接受格式正确的json对象，而是一个以行分隔的json对象列表。很抱歉它应该是：{code>{index:{u index:{u index:“学校”，“学校类型”，“学校id:“1”}{“名称”：“中心学校”，“描述”：“CBSE附属机构”，“街道”：“纳甘”，“城市”：“纸屑”，“州”：“HP”，“zip:“176115”，“位置”：[31.8955385,76.8380405]，“费用”：2000，“标签”：[“高中”，“美丽校园]，“评级”：“3.5\n”}使用换行符分隔要发布到ES的每个文档。如果您想先检查这是否有效，那么我将编辑我的答案以反映这一点。很抱歉，评论中的格式不是很好。

{
  "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]"
  },
