IMG

You can encapsulate multiple IMG parameters in a style, and use the style to process multiple images at a time. For more information, see Image style. The following code provides an example on how to use image style to process an image:

<? php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\OssClient;
// Security risks may arise if you use the AccessKey pair of an Alibaba Cloud account to log on to OSS because the account has permissions on all API operations. We recommend that you use your RAM user's credentials to call API operations or perform routine operations and maintenance. To create a RAM user, log on to the RAM console.
$accessKeyId = "<yourAccessKeyId>";
$accessKeySecret = "<yourAccessKeySecret>";
// The endpoint of the China (Hangzhou) region is used in this example. Specify the actual endpoint.
$endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
$bucket = "<yourBucketName>";
$object = "<yourObjectName>";
// Specify the name of the processed image.
$download_file = "<LocalFileName>";

$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);

// If the image does not exist in the required bucket, you must upload the image to the required bucket.
// $ossClient->uploadFile($bucket, $object, "<yourLocalFile>");

// Specify the image style.
$style = "style/<yourCustomStyleName>";
// Save the image to your local computer.
$options = array(
    OssClient::OSS_FILE_DOWNLOAD => $download_file,
    OssClient::OSS_PROCESS => $style);
$ossClient->getObject($bucket, $object, $options);
// After the IMG is complete, you can delete the source image if you no longer use the image in the bucket.
// $ossClient->deleteObject($bucket, $object);
                            

You can call the ImgSaveAs operation to save the images to the bucket where the source images are stored. The following code provides an example on how to save an processed image:

<? php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\OssClient;

// Security risks may arise if you use the AccessKey pair of an Alibaba Cloud account to log on to OSS because the account has permissions on all API operations. We recommend that you use your RAM user's credentials to call API operations or perform routine operations and maintenance. To create a RAM user, log on to the RAM console.
$accessKeyId = "<yourAccessKeyId>";
$accessKeySecret = "<yourAccessKeySecret>";
// The endpoint of the China (Hangzhou) region is used in this example. Specify the actual endpoint.
$endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
$bucket= "<yourBucketName>";
$object = "<yourObjectName>";
// Specify the name of the processed image.
$save_object = "<saveObjectName>";

function base64url_encode($data)
{
    return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');
}

$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint, false);
// If the image does not exist in the required bucket, you must upload the image to the required bucket.
// $ossClient->uploadFile($bucket, $object, "<yourLocalFile>");

// After you resize the image to a height and width of 100 pixels, rotate the image 90°.
$style = "image/resize,m_fixed,w_100,h_100/rotate,90";

// Save the processed image to the current bucket.
$process = $style.
           '|sys/saveas'.
           ',o_'.base64url_encode($save_object).
           ',b_'.base64url_encode($bucket);
$result = $ossClient->processObject($bucket, $object, $process);

// Display the processed result.
print($result);

URLs of private objects must be signed. OSS does not allow you to add IMG parameters to a signed URL. If you want to process private objects, add IMG parameters to the signature. The following code provides an example on how to add IMG parameters to the signature:

<? php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\OssClient;

// Security risks may arise if you use the AccessKey pair of an Alibaba Cloud account to log on to OSS because the account has permissions on all API operations. We recommend that you use your RAM user's credentials to call API operations or perform routine operations and maintenance. To create a RAM user, log on to the RAM console.
$accessKeyId = "<yourAccessKeyId>";
$accessKeySecret = "<yourAccessKeySecret>";
// The endpoint of the China (Hangzhou) region is used in this example. Specify the actual endpoint.
$endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
$bucket= "<yourBucketName>";
$object = "<yourObjectName>";

$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);

// Generate a signed URL that contains the IMG parameters. The validity period of the URL is 3,600 seconds. The signed URL can be directly accessed by using the browser.
$timeout = 3600;
$options = array(
    OssClient::OSS_PROCESS => "image/resize,m_lfit,h_100,w_100" );
$signedUrl = $ossClient->signUrl($bucket, $object, $timeout, "GET", $options);

print("rtmp url: \n" . $signedUrl);
