(PHP ActiveX) OneDrive -- Upload Large Files with an Upload Session

See more OneDrive Examples

Demonstrates how to upload large files with an upload session. See OneDrive Upload Session for more general information.

Note: This example requires Chilkat v9.5.0.97 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example uses the OAuth client credentials flow.
// See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

// Use your client ID, client secret, and tenant ID in the following lines
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->UpdateString('client_id','2871da2c-8176-4b7f-869b-2311aa82e743');
$json->UpdateString('client_secret','2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH');
$json->UpdateString('scope','https://graph.microsoft.com/.default');
$json->UpdateString('token_endpoint','https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')

// Step 1: Create an upload session

// To begin a large file upload, your app must first request a new upload session. This creates a 
// temporary storage location where the bytes of the file will be saved until the complete file is uploaded. 
// Once the last byte of the file has been uploaded the upload session is completed and the final file is shown 
// in the destination folder.

// Send the following POST to create an upload session:
// If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
// POST /v1.0/users/{user_id}/drive/root:/{path_to_item}:/createUploadSession

$http->SetUrlVar('path_to_item','/somefolder/big.zip');
$http->SetUrlVar('user_id','4fe732c3-322e-4a6b-b729-2fd1eb5c6104');
$url = 'https://graph.microsoft.com/v1.0/users/{$user_id}/drive/root:/{$path_to_item}:/createUploadSession';
// resp is a Chilkat.HttpResponse
$resp = $http->PostJson2($url,'application/json','{}');
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

// If successful, a 200 status code is returned, with the session details (in JSON format).
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonSession = new COM("Chilkat.JsonObject");
$jsonSession->EmitCompact = 0;
$jsonSession->Load($resp->BodyStr);

if ($resp->StatusCode != 200) {

    print $jsonSession->emit() . "\n";
    print 'Response status = ' . $resp->StatusCode . "\n";

    exit;
}

print $jsonSession->emit() . "\n";

// A sample response:

// Step 2: Upload Data in Segments (a.k.a. Fragments or Chunks)

// Microsoft states this requirement: Use a fragment size that is a multiple of 320 KiB (320 * 1024 bytes). 
// Failing to use a fragment size that is a multiple of 320 KiB can result in large file transfers failing after the 
// last fragment is uploaded.  (Note: This is a detail imposed by Microsoft's OneDrive server-side implementation.)

$fragSize = 320 * 1024;
$localFilePath = 'qa_data/zips/big.zip';

// Upload the file big.zip in 320KiB segments.
// Note: The FileSize method returns a signed 32-bit integer.  If the file is potentially larger than 2GB, call FileSizeStr instead to return
// the size of the file as a string, then convert to an integer value.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.FileAccess')
$fac = new COM("Chilkat.FileAccess");
$fileSize = $fac->FileSize($localFilePath);

// Open the file to get the number of fragments.
$success = $fac->OpenForRead($localFilePath);

}

$numFragments = $fac->GetNumBlocks($fragSize);

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Url')
$uploadUrl = new COM("Chilkat.Url");
$uploadUrl->ParseUrl($jsonSession->stringOf('uploadUrl'));

$json->EmitCompact = 0;

$sbRange = new COM("Chilkat.StringBuilder");

// IMPORTANT: The uploadUrl is a temporary URL to be used to upload the fragment.
// It requires no authentication (because the URL itself could only have been obtained from an authenticated
// request to start the upload session).  Therefore, do not allow the upload URL to be publicly seen,
// otherwise anybody could upload to your OneDrive.
