(PHP ActiveX) Upload using Azure Storage Account Shared Access Signature (SAS) Authorization

Sample code to upload binary bytes to a block blob in Azure Cloud Storage using an Azure Storage Account Shared Access Signature (SAS) Authorization. This creates a block blob, or replaces an existing block blob.

Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..

Note: This example requires Chilkat v9.5.0.65 or later.

// Note: This example requires Chilkat v9.5.0.65 or greater.

// Azure Blob Service Example: Upload binary bytes to a block blob.
// This uses a Shared Access Signature (SAS) for Authorization.
// This creates a new block blob or replaces an existing one in its entirety.
// See also: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx

// 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 Azure Storage Blob Service
$bTls = 1;
$port = 443;
$bAutoReconnect = 1;
// In this example, the storage account name is "chilkat".
$success = $rest->Connect('chilkat.blob.core.windows.net',$port,$bTls,$bAutoReconnect);
if ($success != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

// ----------------------------------------------------------------------------------------------
// The code above this comment could be placed inside a function/subroutine within the application
// because the connection does not need to be made for every request.  Once the connection is made
// the app may send many requests..
// ----------------------------------------------------------------------------------------------

// Note: The application does not need to explicitly set the following
// headers: Content-Length, x-ms-date, Authorization.  These headers
// are automatically set by Chilkat.

// Let's load a previously computed Azure Storage Account SAS token and use it.
// See How to Create an Azure Storage Account Shared Access Signature
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbToken = new COM("Chilkat.StringBuilder");
$success = $sbToken->LoadFile('qa_data/tokens/azureStorageAccountSas.txt','utf-8');
if ($success != 1) {
    print 'Failed to load SAS token.' . "\n";
    exit;
}

// Add the Shared Access Signature query params for authorization.
$rest->AddQueryParams($sbToken->getAsString());

// IMPORTANT: Make sure to set the x-ms-blob-type header:
$success = $rest->AddHeader('x-ms-blob-type','BlockBlob');

// IMPORTANT: Make sure to add the x-ms-date header.
// When the header name is "x-ms-date", Chilkat will recognize the keyword "NOW" 
// and will substitute the current system date/time formatted as required by Microsoft.
$success = $rest->AddHeader('x-ms-date','NOW');

// For this example, we'll just load a JPG file into memory..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')
$binData = new COM("Chilkat.BinData");
$success = $binData->LoadFile('qa_data/jpg/starfish.jpg');
if ($success != 1) {
    print 'Failed to load JPG file.' . "\n";
    exit;
}

// Note: The maximum size of a block blob created by uploading in a single step is 64MB.  
// For larger files, the upload must be broken up into blocks.  There is another Chilkat example for that..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbResponse = new COM("Chilkat.StringBuilder");
$success = $rest->FullRequestBd('PUT','/mycontainer/starfish.jpg',$binData,$sbResponse);
if ($success != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

// When successful, the Azure Storage service will respond with a 201 response status code,
// with no response body.
if ($rest->ResponseStatusCode != 201) {
    // Examine the request/response to see what happened.
    print 'response status code = ' . $rest->ResponseStatusCode . "\n";
    print 'response status text = ' . $rest->ResponseStatusText . "\n";
