<?php

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

$success = 1;

// This example uses a previously obtained access token having permission for the 
// Google Drive scope. 
// See Get Google Drive OAuth2 Access Token

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

$http->AuthToken = 'GOOGLE_DRIVE_ACCESS_TOKEN';

// First we want to initiate the resumable upload.
// We send a POST to get a session URI, which will be used to upload the file, and resume if needed.

// Our POST will look like this:

// POST https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable HTTP/1.1
// Authorization: Bearer [YOUR_AUTH_TOKEN]          <-- Chilkat automatically adds this header because the AuthToken property was set.
// Content-Length: 38                               <-- Chilkat will automatically add this header.
// Content-Type: application/json; charset=UTF-8    <-- This is the type of this POST, and is specified in the call to PostJson3.
// X-Upload-Content-Type: application/zip           <-- The type of file we'll be uploading
// X-Upload-Content-Length: 1366807                 <-- The size of the file we'll be uploading
// 
// {
//   "name": "myObject"
// }

$http->SetRequestHeader('X-Upload-Content-Type','application/zip');
$http->SetRequestHeader('X-Upload-Content-Length','1366807');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->UpdateString('name','myZip');

// resp is a Chilkat.HttpResponse
$resp = $http->PostJson3('https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable','application/json',$json);
if ($http->LastMethodSuccess == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

$statusCode = $resp->StatusCode;
if ($statusCode != 200) {
    print $resp->BodyStr . "\n";
    print 'response status = ' . $statusCode . "\n";
    exit;
}

// The session URI is in the "Location" response header:
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbSessionUri = new COM("Chilkat.StringBuilder");
$sbSessionUri->Append($resp->getHeaderField('Location'));
$sessionUri = $sbSessionUri->getAsString();
print 'Session URI: ' . $sessionUri . "\n";

// Here's a sample session URI:  https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=AEnB2UrszR8lDqlo3mtXJw_0rYI_Hi1oVh1NPFcLfoyBq9NcSjk85kFopoZaVEgT38OSmLl0XsObPf4iCSJwHlrOvvIJQ_ckIQ

// -----------------------------------------------------------------------------
// The next step is to upload the file using the session URI:

// We'll send a PUT that looks like this:

// PUT https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=xa298sd_sdlkj2 HTTP/1.1
// Content-Length: 1366807
// Content-Type: application/zip
// 
// [BYTES 0-1366806]

// First remove the X-Upload-Content-Type and X-Upload-Content-Length request headers we specified earlier, so they don't get sent with subsequent requests.
$http->ClearHeaders();

// Because the file is likely large, we'll use SynchronousRequest which allows to to pass an HTTP request object where the body can be streamed directly from a file.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.HttpRequest')
$req = new COM("Chilkat.HttpRequest");

$req->ContentType = 'application/zip';
$req->HttpVerb = 'PUT';

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

$req->Path = $url->PathWithQueryParams;
print 'Path with Query Param: ' . $url->PathWithQueryParams . "\n";

// Specify that the request body is to be streamed directly from a file.
$success = $req->StreamBodyFromFile('qa_data/zips/big.zip');
if ($success == 0) {
    print $req->LastErrorText . "\n";
    exit;
}

// resp is a Chilkat.HttpResponse
$resp = $http->SynchronousRequest($url->Host,$url->Port,$url->Ssl,$req);
if ($http->LastMethodSuccess == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

print $resp->BodyStr . "\n";
print 'response status = ' . $statusCode . "\n";

// Sample output:

// {
//  "kind": "drive#file",
//  "id": "1rx20i53eurtkVQ-RT7Ry8Ct85PgPYMET",
//  "name": "myZip",
//  "mimeType": "application/zip"
// }
// 
// response status = 200
