(PHP ActiveX) S3 Upload String using AWS Signature Version 2Example to upload the contents of a string to the Amazon S3 service, using the older AWS Signature Version 2.
<?php // Demonstrates how to use older AWS S3 Signature Version 2 for uploading the contents // of a string variable to an object in a bucket. // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest') $rest = new COM("Chilkat.Rest"); // Connect to the Amazon AWS REST server. $bTls = 1; $port = 443; $bAutoReconnect = 1; // The file is uploaded to the bucket named "chilkat100", which becomes part of the domain: $success = $rest->Connect('chilkat100.s3.amazonaws.com',$port,$bTls,$bAutoReconnect); // ---------------------------------------------------------------------------- // Important: For buckets created in regions outside us-east-1, // there are three important changes that need to be made. // See Working with S3 Buckets in Non-us-east-1 Regions for the details. // ---------------------------------------------------------------------------- // Provide AWS credentials for the REST call. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.AuthAws') $authAws = new COM("Chilkat.AuthAws"); $authAws->AccessKey = 'AWS_ACCESS_KEY'; $authAws->SecretKey = 'AWS_SECRET_KEY'; $authAws->ServiceName = 's3'; // For AWS Signature Version 2, the following two properties need to be set: $authAws->SignatureVersion = 2; // See http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html#ConstructingTheCanonicalizedResourceElement // The bucket is "chilkat100", and the uriPath is "/hamlet_play.xml", which must match // the URI path passed to the FullRequestString method below. $authAws->CanonicalizedResourceV2 = '/chilkat100/hamlet_play.xml'; $success = $rest->SetAuthAws($authAws); // Load a text file into memory. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.FileAccess') $fac = new COM("Chilkat.FileAccess"); $fileContents = $fac->readEntireTextFile('qa_data/xml/hamlet.xml','utf-8'); if ($fac->LastMethodSuccess != 1) { print $fac->LastErrorText .

(This is optional) $success = $rest->AddHeader('Content-Type','text/xml'); // We can add an "Expect: 100-continue" header so that if the request is rejected // by the server immediately after receiving the request header, it can respond // and the client (Chilkat) can avoid sending the file data. // (this is optional) $success = $rest->AddHeader('Expect','100-continue'); // Upload the file to Amazon S3. $responseBodyStr = $rest->fullRequestString('PUT','/hamlet_play.xml',$fileContents); if ($rest->LastMethodSuccess != 1) { print $rest->LastErrorText .
