从PHP通过curl在ElasticSearch中点击0次，所有点击都来自命令行

Question

我运行以下PHP：

function curl_delete($url)
{
    $ch = curl_init();
    curl_setopt_array($ch, 
    [
        CURLOPT_CUSTOMREQUEST => 'DELETE',
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true
    ]);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

function curl_put($url, $data)
{
    $ch = curl_init();
    curl_setopt_array($ch, 
    [
        CURLOPT_CUSTOMREQUEST => 'PUT',
        CURLOPT_URL => $url,
        CURLOPT_HTTPHEADER =>
        [
            'Content-Type: application/json',
            'Content-Length: ' . strlen($data),
        ],
        CURLOPT_POSTFIELDS => $data,
        CURLOPT_RETURNTRANSFER => true
    ]);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

function curl_post($url, $data)
{
    $ch = curl_init();
    curl_setopt_array($ch, 
    [
        CURLOPT_POST => true,
        CURLOPT_URL => $url,
        CURLOPT_HTTPHEADER => ['Content-Type: application/json'],
        CURLOPT_POSTFIELDS => $data,
        CURLOPT_RETURNTRANSFER => true
    ]);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

echo curl_delete('localhost:9200/my_index?pretty');
echo curl_put('localhost:9200/my_index?pretty', '{"settings": {"number_of_shards": 1}}');
echo curl_post('localhost:9200/my_index/my_type/_bulk?pretty', '
{ "index": { "_id": 1 }}
{ "title": "The quick brown fox" }
{ "index": { "_id": 2 }}
{ "title": "The quick brown fox jumps over the lazy dog" }
{ "index": { "_id": 3 }}
{ "title": "The quick brown fox jumps over the quick dog" }
{ "index": { "_id": 4 }}
{ "title": "Brown fox brown dog" }
');
echo curl_post('localhost:9200/my_index/my_type/_refresh?pretty', '{}');
echo curl_post('localhost:9200/my_index/my_type/_search?pretty', '{}');

我得到以下没有命中的输出：

{
  "acknowledged" : true
}
{
  "acknowledged" : true,
  "shards_acknowledged" : true
}
{
  "took" : 92,
  "errors" : false,
  "items" : [

      "index" : {
        "_index" : "my_index",

        },
        "created" : true,
        "status" : 201
      }
    },
    {
      "index" : {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "2",
        "_version" : 1,
        "result" : "created",

      }
    },
    {
      "index" : {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "3",
        "_version" : 1,
        "result" : "created",
        "_shards" : {
          "total" : 2,
          "successful" : 1,
          "failed" : 0
        },
        "created" : true,
        "status" : 201
      }
    },
    {
      "index" : {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "4",

        "result" : "created",
        "_shards" : {
          "total" : 2,
          "successful" : 1,
          "failed" : 0
        },
        "created" : true,
        "status" : 201
      }
    }
  ]
}
{
  "_index" : "my_index",
  "_type" : "my_type",
  "_id" : "_refresh",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "created" : true
}
{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "failed" : 0
  },
  "hits" : {
    "total" : 0,
    "max_score" : null,
    "hits" : [ ]
  }
}

“D:\Program Files\curl\bin\curl.exe”-XpostLocalHost:9200/my_index/my_type/_search？pretty“-h”content-type：application/json“-d”{}“

我得到了所有的点击率，因为我应该：

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "failed" : 0
  },
  "hits" : {
    "total" : 4,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "1",
        "_score" : 1.0,
        "_source" : {
          "title" : "The quick brown fox"
        }
      },
      {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "2",
        "_score" : 1.0,
        "_source" : {
          "title" : "The quick brown fox jumps over the lazy dog"
        }
      },
      {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "3",
        "_score" : 1.0,
        "_source" : {
          "title" : "The quick brown fox jumps over the quick dog"
        }
      },
      {
        "_index" : "my_index",
        "_type" : "my_type",
        "_id" : "4",
        "_score" : 1.0,
        "_source" : {
          "title" : "Brown fox brown dog"
        }
      }
    ]
  }
}

有人能告诉我最后一行PHP有什么问题吗？为什么没有点击？

Answer 1

在运行批量查询时，可以看到所有文档都已创建。但是，索引还没有刷新，因此在立即运行搜索时不会获得任何点击量。

您可以做的是在搜索之前调用refresh，如下所示：

echo curl_post('localhost:9200/my_index/_refresh', '{}');

或者简单地向批量调用添加refresh参数，如下所示：

echo curl_post('localhost:9200/my_index/my_type/_bulk?pretty=true&refresh=true', ...

然后您可以正常发出搜索查询：

echo curl_post('localhost:9200/my_index/my_type/_search?pretty', '{}');
