Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$success = true;

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

$http = new CkHttp();

$http->put_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');

$json = new CkJsonObject();
$json->UpdateString('name','myZip');

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

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

// The session URI is in the "Location" response header:
$sbSessionUri = new CkStringBuilder();
$sbSessionUri->Append($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.
$req = new CkHttpRequest();

$req->put_ContentType('application/zip');
$req->put_HttpVerb('PUT');

$url = new CkUrl();
$url->ParseUrl($sessionUri);

$req->put_Path($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 == false) {
    print $req->lastErrorText() . "\n";
    exit;
}

// resp is a CkHttpResponse
$resp = $http->SynchronousRequest($url->host(),$url->get_Port(),$url->get_Ssl(),$req);
if ($http->get_LastMethodSuccess() == false) {
    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
