(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.

<?php

//  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.

$rest = new COM("Chilkat_9_5_0.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
$sbToken = new COM("Chilkat_9_5_0.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..
$binData = new COM("Chilkat_9_5_0.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..
$sbResponse = new COM("Chilkat_9_5_0.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";
    print 'response header: ' . $rest->ResponseHeader . "\n";
    print 'response body (if any): ' . $sbResponse->getAsString() . "\n";
    print '---' . "\n";
    print 'LastRequestStartLine: ' . $rest->LastRequestStartLine . "\n";
    print 'LastRequestHeader: ' . $rest->LastRequestHeader . "\n";
    print 'Failed.' . "\n";
    exit;
}

print 'Success.' . "\n";
