具有PHP连接的Elasticsearch无法正常工作
我正在使用Elasticsearch 8.1。它在端口9200上运行。当我从Postman执行时，
https://localhost:9200/learn/_search
具有授权：类型：基本auth和用户名＆amp;密码，我可以看到结果。
但是现在我想使用PHP实现此目标。我在作曲家中安装了“ Elasticsearch/elasticsearch”：“^8.0”。这是我尝试过的代码。
use Elastic\Elasticsearch\ClientBuilder;
$hosts = [
'host' => 'localhost',
'port' => '9200',
'scheme' => 'https',
'user' => 'elastic',
'pass' => 'LisRrIul9oMKh2deJkMv'
];
$client = ClientBuilder::create()
->setHosts($hosts)
->build();
$params = [
'index' => 'learn',
];
$results = $client->search($params);
echo "<pre>";
print_r($results);
我得到了

I am using Elasticsearch 8.1. It is running on port 9200. When I execute from POSTMAN,
https://localhost:9200/learn/_search
with Authorization: Type: Basic Auth and username & password, I can see the result.
But now I want to implement this using PHP. I have installed "elasticsearch/elasticsearch": "^8.0" in my composer. This is the code I have tried.
use Elastic\Elasticsearch\ClientBuilder;
$hosts = [
'host' => 'localhost',
'port' => '9200',
'scheme' => 'https',
'user' => 'elastic',
'pass' => 'LisRrIul9oMKh2deJkMv'
];
$client = ClientBuilder::create()
->setHosts($hosts)
->build();
$params = [
'index' => 'learn',
];
$results = $client->search($params);
echo "<pre>";
print_r($results);
I am getting

尝试一下
Try this
您的 ClientBuilder 调用似乎有问题，因为响应表明至少端口设置不起作用（因为它包含 localhost 端口 80）。
尝试在一个 URL 字符串中传递参数：
要获取索引，您可以使用
cat而不是search：There seems to be something wrong with your
ClientBuildercall, since the response indicates that at least the port setting did not work (as it containslocalhost Port 80).Try passing the parameters in one URL string:
To then get the indices, you can use
catinstead ofsearch:
