Upload Application Specific Data

See more Google Drive Examples

Uploads a text file (application specific data) where the contents of the file are contained in a string variable. Perl

use chilkat();

$success = 0;

$success = 1;

# It requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example uses a previously obtained access token having permission for the 
# Google Drive application specific data scope.
$jsonToken = chilkat::CkJsonObject->new();
$success = $jsonToken->LoadFile("qa_data/tokens/googleDriveAppData.json");

$gAuth = chilkat::CkAuthGoogle->new();
$gAuth->put_AccessToken($jsonToken->stringOf("access_token"));

$rest = chilkat::CkRest->new();

# Connect using TLS.
$bAutoReconnect = 1;
$success = $rest->Connect("www.googleapis.com",443,1,$bAutoReconnect);

# Provide the authentication credentials (i.e. the access token)
$rest->SetAuthGoogle($gAuth);

# A multipart upload to Google Drive needs a multipart/related Content-Type
$rest->AddHeader("Content-Type","multipart/related");

# Specify each part of the request.

# The 1st part is JSON with information about the file.
$rest->put_PartSelector("1");
$rest->AddHeader("Content-Type","application/json; charset=UTF-8");

$json = chilkat::CkJsonObject->new();
$json->put_EmitCompact(0);

$json->UpdateString("name","helloWorld.txt");
$json->UpdateString("description","A simple text file that says Hello World.");
$json->UpdateString("mimeType","text/plain");
# Specifiy the application-specific data folder.
$json->UpdateString("parents[0]","appDataFolder");
$rest->SetMultipartBodyString($json->emit());

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

# The JSON looks like this:
# {
#   "name": "helloWorld.txt",
#   "description": "A simple text file that says Hello World.",
#   "mimeType": "text/plain",
#   "parents": [
#     "appDataFolder"
#   ]
# }

# The 2nd part is the file content.
# In this case, we'll upload a simple text file containing "Hello World!"
$rest->put_PartSelector("2");
$rest->AddHeader("Content-Type","text/plain");

$fileContents = "Hello World!";
$rest->SetMultipartBodyString($fileContents);

$jsonResponse = $rest->fullRequestMultipart("POST","/upload/drive/v3/files?uploadType=multipart");
if ($rest->get_LastMethodSuccess() != 1) {
    print $rest->lastErrorText() . "\r\n";
    exit;
}

# A successful response will have a status code equal to 200.
if ($rest->get_ResponseStatusCode() != 200) {
    print "response status code = " . $rest->get_ResponseStatusCode() . "\r\n";
    print "response status text = " . $rest->responseStatusText() . "\r\n";
    print "response header: " . $rest->responseHeader() . "\r\n";
    print "response JSON: " . $jsonResponse . "\r\n";
    exit;
}

# Show the JSON response.
$json->Load($jsonResponse);

# Show the full JSON response.
$json->put_EmitCompact(0);
print $json->emit() . "\r\n";

# A successful response looks like this:
# {
#   "kind": "drive#file",
#   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
#   "name": "Untitled",
#   "mimeType": "text/plain"
# }

# Get the fileId:
print "fileId: " . $json->stringOf("id") . "\r\n";
