Google Drive Insert Permission

See more Google Drive Examples

This example demonstrates how to insert a permission for a file (see https://developers.google.com/drive/v2/reference/permissions/insert)

The impetus for creating this example was a need to be able to view files uploaded using a service account key in the Google Drive web interface. When using a service account access token, the files your application will see are those for the service account, and not the files for your main account. For example, the Google Account I use for testing has a username of "support@chilkatcloud.com". (Don't send email to support@chilkatcloud.com, it's just use for testing and not interactively read.) I use "support@chilkatcloud.com" when I log into Google interactively to view files in Google Drive at https://drive.google.com/drive/my-drive.

The files I upload to Google Drive using a service account key won't be visible in the browser UI. To make them visible, you need to insert a permission for the file so that the main user account, which in this case is "support@chilkatcloud.com", is a reader. After the permission is inserted, the file will be visible under "Shared with me" -- as if another Google Drive account shared the file with you.

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 scope.

$gAuth = chilkat::CkAuthGoogle->new();
$gAuth->put_AccessToken("GOOGLE-DRIVE-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);

$rest->AddHeader("Content-Type","application/json; charset=UTF-8");

$json = chilkat::CkJsonObject->new();
$json->AppendString("role","reader");
$json->AppendString("type","user");
$json->AppendString("value",'support@chilkatcloud.com');

# A note from a Chilkat customer:
# 
#   My coding attempt was frustrated because I tried a role of "owner".
#   Even when providing the extra parameter of ...?transferOwnership=true
#   that approach fails (400, Bad Request).
# 

# This example is inserting a permission for the file whose fileId is "0By-hrxCCDzSQUGxJY0hzNUFpNmc".
$jsonResponse = $rest->fullRequestString("POST","/drive/v2/files/0By-hrxCCDzSQUGxJY0hzNUFpNmc/permissions",$json->emit());
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";

print "Success." . "\r\n";
