Region

Each request carries an region called regionId. Since most of the requested regions are the same, it is not necessary to set the region for each request, Please refer to Regions and Zones.

Specify the Region for the Request

If you specify an Region separately for the request, the client Region or default Region will not be used.

<?php

use AlibabaCloud\Client\AlibabaCloud;

$result = AlibabaCloud::rpc()
                      ->client('client1') // Specify client, if not, the default client is used by default
                      ->regionId('cn-hangzhou') // Specify the requested Region as cn-hangzhou
                      ->product('Cdn')
                      ->version('2014-11-11')
                      ->action('DescribeCdnService')
                      ->method('POST')
                      ->request();

Specify the Region for the Client

You can also specify an Region when you create a client, and if the client's request is not specified Region, use the client's Region.

<?php

use AlibabaCloud\Client\AlibabaCloud;

AlibabaCloud::accessKeyClient('accessKeyId', 'accessKeySecret')
            ->regionId('cn-hangzhou') // Specify the client Region as cn-hangzhou
            ->name('client1');

Set the Default Region

If both the Request and Request's client do not have an Region, the default Region will be used.

<?php

use AlibabaCloud\Client\AlibabaCloud;

// Set the default Region to cn-hangzhou
AlibabaCloud::setDefaultRegionId('cn-hangzhou');

// Get the default Region
AlibabaCloud::getDefaultRegionId();
