使用PHP在Elasticsearch中搜索时出现错误 [英] Errors upon searching in Elasticsearch using PHP

问题描述

我正在尝试使用PHP搜索索引.我已经下载了供应商文件，并且已经成功建立了连接.但是，我收到一些错误.这些错误并非总是会发生.如果我刷新浏览器几次，我将获得正确的输出.这是我的代码:

I am trying to search through my index using PHP. I have downloaded the vendor files and I have built the connection successfully. However, I am receiving some errors. These errors don't always occur though. If I refresh the browser a couple of times, I will get the correct output. Here's my code:

require_once 'init.php';

$json = '{"aggs": { "group_by_date": { "terms": { "field": "arrivalDate" } } } }';

    $params = [
        'index' => 'pickups',
        'type' => 'external',
        'body' => $json 
        ];
    
$results = $es->search($params);

echo $results['hits']['total'];

init.php是Elasticsearch的连接文件.刷新屏幕时可能会发生2种不同的输出.第一个输出是正确的输出.另一个只是错误.错误如下:

The init.php is the connection file to Elasticsearch. There are 2 different outputs that may occur upon refreshing the screen. The first output is the correct output. The other is just errors. Here are the errors:

致命错误:未捕获的Elasticsearch \ Common \ Exceptions \ Missing404Exception:{"statusCode":404，"error":"未找到}在C:\ wamp64 \ www \ DataAggregation \ vendor \ elasticsearch \ elasticsearch \src \ Elasticsearch \ Connections \ Connection.php在第602行

Fatal error: Uncaught Elasticsearch\Common\Exceptions\BadRequest400Exception: in C:\wamp64\www\DataAggregation\vendor\elasticsearch\elasticsearch\src\Elasticsearch\Connections\Connection.php on line 610

这些错误的原因是什么，我该如何解决?

What are the cause of these errors and how can I fix them?

推荐答案

似乎您尚未启动Web服务器，启动ES Web服务器以连接php.

It seems you have not started web server, start ES web server to connect with php.
