如何在Yii2项目中添加PHP请求

use yii\httpclient\Client;

$client = new Client();

$response = $client->createRequest()
    ->setMethod('GET')
    ->setUrl('http://example.com/api')
    ->send();

$response = $client->createRequest()
    ->setMethod('POST')
    ->setUrl('http://example.com/api')
    ->setData(['param1' => 'value1', 'param2' => 'value2'])
    ->send();

if ($response->isOk) {
    $statusCode = $response->getStatusCode();
    $content = $response->getContent();
} else {
    // 处理请求失败的情况
}
