Perl Requires Chilkat v11.0.0+

Google Drive - Resumable Upload

See more Google Drive Examples

Demonstrates how to do a resumable upload to Google Drive. Perl

use chilkat();

$success = 0;

#  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

$http = chilkat::CkHttp->new();

$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 HttpJson.
#  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 = chilkat::CkJsonObject->new();
$json->UpdateString("name","myZip");

$resp = chilkat::CkHttpResponse->new();
$success = $http->HttpJson("POST","https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable",$json,"application/json",$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

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

#  The session URI is in the "Location" response header:
$sbSessionUri = chilkat::CkStringBuilder->new();
$sbSessionUri->Append($resp->getHeaderField("Location"));
$sessionUri = $sbSessionUri->getAsString();
print "Session URI: " . $sessionUri . "\r\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 HttpSReq which allows to to pass an HTTP request object where the body can be streamed directly from a file.
$req = chilkat::CkHttpRequest->new();

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

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

$req->put_Path($url->pathWithQueryParams());
print "Path with Query Param: " . $url->pathWithQueryParams() . "\r\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() . "\r\n";
    exit;
}

$success = $http->HttpSReq($url->host(),$url->get_Port(),$url->get_Ssl(),$req,$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

print $resp->bodyStr() . "\r\n";
print "response status = " . $resp->get_StatusCode() . "\r\n";

#  Sample output:

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