(PHP Extension) Generate an AWS (S3) Pre-Signed URL using Signature V4Demonstrates how to generate a pre-signed URL using AWS Signature Version 4. This example generates a pre-signed URL for the Amazon S3 service. Note: this example requires Chilkat v9.5.0.66 or greater.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Note: This example requires Chilkat v9.5.0.66 or greater. $http = new CkHttp(); $http->put_AwsAccessKey('AWS_ACCESS_KEY'); $http->put_AwsSecretKey('AWS_SECRET_KEY'); // Make sure to set your AWS region correctly $http->put_AwsRegion('us-east-1'); $bucketName = 'chilkat100'; $objectName = 'starfish/starfish.jpg'; $localFilePath = 'qa_output/starfish.jpg'; $awsService = 's3'; // The signed URL will be valid for this number of seconds: $numSecondsValid = 86400; // Choose between a URL beginning with "http://" or "https://"... $bUseHttps = false; // Generate the pre-signed URL $preSignedUrl = $http->s3_GenerateUrlV4($bUseHttps,$bucketName,$objectName,$numSecondsValid,$awsService); if ($http->get_LastMethodSuccess() != true) { print $http->lastErrorText() .
