Upload file to Google Drive via API - php

Everyone
I need to upload file to Google Drive via the API, I did exactly what it is mention https://developers.google.com/drive/quickstart-php.
I had generated the access token and saved it in the file, the problem is that it only works for the first time and next time it gives error
OAuth2 token, message: '{ "error" : "invalid_grant" }
We only need to upload files to Google drive (our own account) after getting from the users by form.
I had tried scripts from many tutorial but it didn't seem to work.
I had also tried with offline access permission but still no luck.
Update:
Here it the code that I use to generate access token
require_once APP_PATH.'_includes/google_drive/Google_Client.php';
require_once APP_PATH.'_includes/google_drive/contrib/Google_DriveService.php';
$drive = new Google_Client();
$drive->setClientId('xxxxxxxxxxxxxxxx');
$drive->setClientSecret('xxxxxxxxxxxxxxx');
$drive->setRedirectUri('urn:ietf:wg:oauth:2.0:oob');
$drive->setScopes(array('https://www.googleapis.com/auth/drive'));
$gdrive = new Google_DriveService($drive);
$url = $drive->createAuthUrl();
$authorizationCode = trim(fgets(STDIN));
$token = $drive->authenticate($authorizationCode);
And then I used this code
$drive = new Google_Client();
$drive->setClientId('xxxxxxxxxxx');
$drive->setClientSecret('xxxxxxxxxxxxxxx');
$drive->setRedirectUri('urn:ietf:wg:oauth:2.0:oob');
$drive->setScopes(array('https://www.googleapis.com/auth/drive'));
$gdrive = new Google_DriveService($drive);
$_GET['code']= '4/axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
file_put_contents('token.json', $drive->authenticate());
$drive->setAccessToken(file_get_contents('token.json'));
$doc = new Google_DriveFile();
$doc->setTitle('Test Document');
$doc->setDescription('Test description');
$doc->setMimeType('text/plain');
$content = file_get_contents('document.txt');
$output = $gdrive->files->insert($doc, array(
'data' => $content,
'mimeType' => 'text/plain',
));
print_r($output);
it works good and but when I run the page again it says
Fatal error: Uncaught exception 'Google_AuthException' with message 'Error fetching OAuth2 access token, message: 'invalid_grant'' in ...Google_OAuth2.php on line 115
any help is appreciated.

Based on #BurcuDogan's comment, commenting out authenticate method resolved the issue.
//file_put_contents('token.json', $drive->authenticate());

Undefined type 'Google_Service_Oauth2' intelephense(1009) PHP

I currently modify my php script using namespace. I've done with the scripts but there are problem with Google API package
// create Client Request to access Google API
$client = new \Google_Client(); => THIS ONE WORKS
$client->setClientId($clientID);
$client->setClientSecret($clientSecret);
$client->setRedirectUri($redirectUri);
$client->addScope("email");
$client->addScope("profile");
$accessToken = $key;
// Get $id_token via HTTPS POST.
try{
$arrToken = $client->setAccessToken($accessToken);
// get profile info
$google_oauth = new \Google_Service_Oauth2($client); => IT DOESNT
$google_account_info = $google_oauth->userinfo->get();
$checkEmail = $google_account_info->email;
$name = $google_account_info->name;
$googleId = $google_account_info->id;
}
Here is the error
Undefined type 'Google_Service_Oauth2' intelephense(1009)
If I do not use namespace, it has no problem. This one really weird.

How to connect to a Google Drive API and get the AccessToken

I'm here with a little problem to connect my script with a Google Drive API using a credentials json file.
This is my code:
$oauth_credentials = __DIR__.'\credentials.json';
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
$client = new Google\Client();
$client->setAccessType('offline');
$client->setAuthConfig($oauth_credentials);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/drive");
if (isset($_GET['code'])) {
$token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
var_dump($token);
}
Obviously I used composer to add google apiclient project to my script, and I used the cloud console of google to enable Drive API and create the credentials for this, and I used the credentials.json file downloaded of Google Console.
All is apparently good, I added a test account and used this account to accept permissions to use the Drive API.
Using the playground, in this URL https://developers.google.com/oauthplayground I test my credentials and I get the authorization code to create a refresh token and access token, but when i use this authorization code in my script the result is this: ""
'error' => string 'invalid_grant' (length=13)
'error_description' => string 'Bad Request' (length=11)
Any suggests? this code is exactly like the code appear in the Google examples.
My problem is that the focus is wrong way, I create a service account and generate the json credentials file and I use this code for upload a file:
putenv('GOOGLE_APPLICATION_CREDENTIALS=credentials.json');
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(['https://www.googleapis.com/auth/drive.file']);
try {
$service = new Google_Service_Drive($client);
$file_path = 'example.txt';
$file = new Google_Service_Drive_DriveFile();
$file->setName('example.txt');
$file->setParents([$this->folder_id]);
$file->setDescription('Example description text');
$result = $service->files->create($file,[
'data' => file_get_contents($file_path),
'mimeType' => 'text/plain',
'uploadType' => 'text'
]);
echo 'Link to the uploaded file';
}
catch(Google_Service_Exception $gs)
{
$m = json_decode($gs->getMessage());
echo $m->error->message;
}
catch(Exception $e)
{
echo $e->getMessage();
}

Google Drive API every time asking for authentication code

I'm using google drive api to upload a file to google drive using php, but it every time asking me for authentication code fof my application.
I have followed the steps given in the URL below
https://developers.google.com/drive/web/quickstart/quickstart-php
My Code:
require_once 'src/Google/autoload.php';
$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('clientid');
$client->setClientSecret('clientsecret');
$client->setRedirectUri('url');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
$service = new Google_Service_Drive($client);
$authUrl = $client->createAuthUrl();
try{
//Request authorization
print "Please visit:<br/>$authUrl<br/>\n";
print "Please enter the auth code:\n";
//
$authCode = trim(fgets(STDIN));
// Exchange authorization code for access token
$accessToken = $client->authenticate($authCode);
$client->setAccessToken($accessToken);
//Insert a file
$file = new Google_Service_Drive_DriveFile();
$file->setTitle('document.txt');
$file->setDescription('A test document');
$file->setMimeType('text/plain');
$data = file_get_contents('document.txt');
$createdFile = $service->files->insert($file, array(
'data' => $data,
'mimeType' => 'text/plain',
));
print_r($createdFile);
}catch(apiServiceException $e){
echo $e->getMessage();
}
Response :
https://accounts.google.com/o/oauth2/auth?response_type=code&redirect_uri=REDIRECT_URL&client_id=CLIENT_ID&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&access_type=online&approval_prompt=auto
I have did more debugging for this issue and last i can upload files to google drive using PHP.
But for this we have to authorize the code using manually according to google api
then we will get the refresh token and using that token we can upload file to google drive every time whout asking any key
I have added code here https://rgknowledgebase.wordpress.com/2015/06/05/php-upload-file-to-google-drive/

access drive with access token

struggling to understand the oauth2 token and refresh token processes
ive got this code
$url = 'https://www.googleapis.com/oauth2/v3/token';
$data = array('client_id' => 'clientid', 'client_secret' => 'secret','refresh_token' => 'token','grant_type' => 'refresh_token');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded",
'method' => 'POST',
'approval_prompt'=>'force',
'access_type'=>'offline',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
that code above gives me an access token , and i followed this link suggested by one fellow stackoverflower, pinoyyid, BUT , im confunsed on how to correctly use the resulting access token to access drive and copy a file...
all the process ive seen usually involves $client = new Google_Client() and im not sure on how to use the whole POST http://..... thing, so basically i need to figure out if i use the access token i got with the code above in a new instance of google client, or i simply do a post to a url with necesary info ( which im not clear on also ) any help/clarification is appreciated guys really
EDIT #1
what i want to achieve is to allow the end user to access my drive via my webpage, to let them copy a spreadsheet in my drive , and access it via my website, to store data on the spreadsheet,the spreadsheet will always be on my drive, never on the end user
EDIT #2
code as per your posts is as follows, using the service account,,,,the files are inside that gmail account which i created on the api console a service account
<?php
require 'Google/autoload.php';
$client = new Google_Client();
// Replace this with your application name.
$client->setApplicationName("TEST");
// Replace this with the service you are using.
$service = new Google_Service_Drive($client);
// This file location should point to the private key file.
$key = file_get_contents($_SERVER['DOCUMENT_ROOT'] . '/number-privatekey.p12');
$user_to_impersonate = 'admin#testpr.com';
$cred = new Google_Auth_AssertionCredentials(
'number#developer.gserviceaccount.com',
array('https://www.googleapis.com/auth/drive'), ****//this here has to be drive not drive.file
$key,
'notasecret',
'http://oauth.net/grant_type/jwt/1.0/bearer',
$user_to_impersonate
);
$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
$client->getAuth()->refreshTokenWithAssertion();
}
$originFileId = "longnumber";
$copyTitle = 'copied';
$newfile = copyFile($service, $originFileId, $copyTitle);
print_r($newfile);
function copyFile($service, $originFileId, $copyTitle)
{
$copiedFile = new Google_Service_Drive_DriveFile();
$copiedFile->setTitle($copyTitle);
try {
return $service->files->copy($originFileId, $copiedFile);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
return NULL;
}
?>
so got it working just now, ty all for your time guys really and edited my post to reflect the dang thing
If you want to give the end user access to your drive, you have to give your application authority to make API calls on behalf of a user (in this case you) in your domain. For this you have to set up a service account and generate a p12 key in the Google Developers Console. You have to enter the https://www.googleapis.com/auth/drive API scope in your Admin Console as well.
Full explanation and examples can be found here: https://developers.google.com/api-client-library/php/auth/service-accounts.
To achieve this you also need the Google API's client library: https://github.com/google/google-api-php-client (also mentioned in the Google manual).
Code example to let users make API calls on behalf of one of your accounts: https://developers.google.com/api-client-library/php/guide/aaa_oauth2_service

Uploading the files to same google drive using php

I was wondering is there any method to upload the files directly to our own Google drive by using php , Currently i am using a method like this.
$drive = new Google_Client();
$drive->setClientId($client_id);
$drive->setClientSecret($client_secret);
$drive->setRedirectUri($redirect_uri);
$drive->setScopes(array('https://www.googleapis.com/auth/drive'));
$gdrive = new Google_DriveService($drive);
$_GET['code'] = 'ya2-------------------------OZXiA';
//file_put_contents('token.json', $drive->authenticate());
$drive->setAccessToken(file_get_contents('token.json'));
$doc = new Google_DriveFile();
$doc->setTitle('Test Document');
$doc->setDescription('Test description');
$doc->setMimeType('text/plain');
$content = file_get_contents('/assets/new--detils.txt');
$output = $gdrive->files->insert($doc, array(
'data' => $content,
'mimeType' => 'text/plain',
));
print_r($output);
But this shows an error as
Fatal error: Uncaught exception Google_AuthException with message 'Error fetching OAuth2 access token, message: 'invalid_grant'' in /var/www/path/src/auth/Google_OAuth2.php:115
Here i am using $_GET['code'] = 'ya2-------------------------OZXiA' generated for that app,
Can anyone please suggest a method to do this, thanks in advance.
Not sure if it helps but I found this looking through Google Code...
"You'll get the invalid_grant error when you try to use the same authorization code."
I found it here: https://code.google.com/p/google-api-php-client/issues/detail?id=94
Not sure if that will help you or not...
Also found this tutorial: http://25labs.com/tutorial-implementing-google-api-using-oauth-2-0-in-php/
$drive = new Google_Client();
$drive->setClientId($client_id);
$drive->setClientSecret($client_secret);
$drive->setRedirectUri($redirect_uri);
**$drive->setAccessType('offline');**
$authUrl = $client->createAuthUrl();
echo $authUrl;
Now go the auth url and get the refresh token and other things.
Make sure this is the first time you are asking for permission, if you aren't then you wont get the refreshtoken which is necessary to make authtokens in the future.
If you have already give permissions just go to your google account and revoke the permissions of the app.
This is what you should have in the file which you are redirecting too.
$tokeninfo = $drive->getAccessToken();
print_r($tokeninfo);
Now save the tokeninfo in a file like "token.json".
Now go back to the original file which will contain the code for upload.
$drive = new Google_Client();
$drive->setClientId($client_id);
$drive->setClientSecret($client_secret);
$drive->setRedirectUri($redirect_uri);
$drive->setScopes(array('https://www.googleapis.com/auth/drive'));
$drive->setAccessType('offline');
$service = new Google_Service_Drive($drive);
$refreshToken = "Your refresh token";
/* get it from token.json and it will look some like this 1**\/**asasfasfsfsd
remove the \ since this is actually json encoded.*/
$tokens = file_get_contents(TOKEN); /*TOKEN = the token.json file*/
$drive->setAccessToken($tokens);
if ($drive->isAccessTokenExpired()) {
$drive->refreshToken($refreshToken);
file_put_contents(TOKEN,$drive->getAccessToken());
}
Now you have done the authentication and just need to upload the file.
if ($drive->getAccessToken()) {
$file = new Google_Service_Drive_DriveFile();
$file->title ="the file name";
/*the upload code can be found in the examples*/
}
Note
The file you upload cannot be downloaded by other ppl, you need to set googlepermissions to make the file shared.
Just drop a comment if you need to code to add permissions.
