Milvus 2.2 gRPC Php 客户端。

文档

兼容性

安装

在终端运行 composer composer require hasanmertermis/milvus-php-client 或在 composer.json 中添加 hasanmertermis/milvus-php-client

示例

客户端

use Hasanmertermis\MilvusPhpClient\Domain\Milvus;
$client = new Milvus();

连接

connection 方法设置连接参数。如果未设置参数，则默认主机为 localhost，端口为 19530。但如果设置了参数，主机名和端口将设置为输入的值。

use Hasanmertermis\MilvusPhpClient\Domain\Milvus;

//Default use
$client = new Milvus();
$client->connection("example.com", 19530);

getConnectionInfo() 方法获取连接参数和 isConnected 信息。

响应

[
'host' => "localhost",
'port' => 19530,
'isConnected' => false
];
