php - Elasticsearch批量数据插入-JsonParseException [意外字符-使用PHP

Question

使用PHP curl方法为大容量数据建立索引时，出现了"error":"JsonParseException[Unexpected character (':' (code 58)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: [B@14abb68; line: 1, column: 18]]","status":500}这个异常

请在下面找到我正在使用的相同代码，并让我知道这里可能有什么问题。

<?php
 $ch = curl_init();
$method = "POST";
$url = "http://192.168.1.204/myindex/test/_bulk";


$qry = '
{"index":{"_index": "myindex","_type":"test"}}
{
    "product_id": 1,
    "title": "mobile"
}
{"index":{"_index": "myindex","_type":"test"}}
{
    "product_id": 2,
    "title": "laptop",
}
';

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PORT, 9200);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, strtoupper($method));
curl_setopt($ch, CURLOPT_POSTFIELDS, $qry);

$result = curl_exec($ch);
curl_close($ch);
  echo $result;

?>

Answer 1

您使用的格式不正确(第二个元素还有一个逗号)。
它应该是:

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

从 elasticsearch - bulk的文档中提取

因此，您应该使用以下格式添加数据:

{"index":{"_index": "myindex","_type":"test"}}
{"product_id": 1,"title": "mobile"}
{"index":{"_index": "myindex","_type":"test"}}
{"product_id": 2,"title": "laptop"}
