Question

每次我按照弹性搜索中的创建索引，映射和添加数据的说明我都有错误。我正在使用邮递员。首先，我创建索引：

POST http://localhost:9200/schools

（实际上，我必须使用put来成功创建）

接下来，我创建映射和添加数据：

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
    }

Answer 1

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，直到你可以进入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"
}

您可以使用工具格式化和验证JSON，以确保它是有效的JSON。以下是一些例子。

我看到的东西与我的问题类似。我的问题解决了！

Elasticsearch Bulk API - Unexpected end-of-input: expected close marker for ARRAY

Answer 3

RecyclerView

Answer 4

要将数据加载到Elasticsearch，请使用REST API端点为'/ _bulk' 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'内容类型：application / x-ndjson'-XPOST'elasticsearchhost：port / index-name-sample / _bulk？pretty'--data-binary @ sample.json

在您的情况下，请求将如下所示： 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：数据的最后一行必须以换行符\ n结尾。每个换行符前面都可以有一个回车符\ r。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
}

无法在Elasticsearch中创建映射和添加数据
