Enable Google Driver API

Enabling the API is the get-go step in creating a simple file upload awarding. Log in to Google and visit

Google Drive – Enable API Key

Creating a Project in Google Driver API

Afterward clicking on Enable the Driver button yous'll see a modal that asks you to give the project a name.

Give Name to Project

Then the adjacent step is to select the fashion through which you will be using this API. Here you select Web Browser as an option.

Select the Fashion

Configure OAuth Client

After the selection of mode, you will be prompted with the Origin URL. You lot will access the drive information through this URL. So, our current URL will be http://localhost.

Configure your Oauth Client

Client Configuration File

In the Final Footstep, y'all volition see a download button that tells y'all to Download Client Configuration. This file is of type JSON format and contains customer ID, client surreptitious, redirect_uris, and javascript_origins.
So download it and salvage information technology in your project root without irresolute its proper name.

Final stride is to download client configuration

Installation and Configure Google Client Library in your project

Open final in your project root and type beneath command. This will install the apiclient into your project.

composer require google/apiclient:^2.0        

PS C:\xampp\htdocs\examples> composer require google/apiclient:^two.0 ./composer.json has been created Loading composer repositories with packet information Updating dependencies (including require-dev) Package operations: 12 installs, 0 updates, 0 removals     - Installing psr/http-message (1.0.ane): Loading from cache     - Installing guzzlehttp/psr7 (i.2.3): Downloading (100%)     - Installing guzzlehttp/promises (v1.3.1): Loading from cache     - Installing guzzlehttp/guzzle (6.2.0): Downloading (100%)     - Installing phpseclib/phpseclib (two.0.28): Downloading (100%)     - Installing psr/log (i.1.three): Downloading (100%)     - Installing monolog/monolog (ane.25.4): Downloading (100%)     - Installing firebase/php-jwt (v3.0.0): Downloading (100%)     - Installing google/apiclient-services (v0.139): Downloading (100%)     - Installing psr/enshroud (1.0.1): Downloading (100%)     - Installing google/auth (v0.8): Downloading (100%)     - Installing google/apiclient (v2.0.0): Downloading (100%) phpseclib/phpseclib suggests installing ext-libsodium (SSH2/SFTP can make utilize of some algorithms provided by the libsodium-php extension.) phpseclib/phpseclib suggests installing ext-mcrypt (Install the Mcrypt extension in social club to speed up a few other cryptographic operations.) phpseclib/phpseclib suggests installing ext-gmp (Install the GMP (GNU Multiple Precision) extension in order to speed up arbitrary precision integer arithmetics operations.) monolog/monolog suggests installing graylog2/gelf-php (Allow sending log messages to a GrayLog2 server) monolog/monolog suggests installing sentry/scout (Allow sending log messages to a Spotter server) monolog/monolog suggests installing doctrine/couchdb (Allow sending log messages to a CouchDB server) monolog/monolog suggests installing ruflin/elastica (Let sending log messages to an Rubberband Search server) monolog/monolog suggests installing php-amqplib/php-amqplib (Permit sending log messages to an AMQP server using php-amqplib) monolog/monolog suggests installing ext-amqp (Let sending log letters to an AMQP server (ane.0+ required)) monolog/monolog suggests installing ext-mongo (Permit sending log letters to a MongoDB server) monolog/monolog suggests installing mongodb/mongodb (Allow sending log messages to a MongoDB server via PHP Driver) monolog/monolog suggests installing aws/aws-sdk-php (Allow sending log messages to AWS services like DynamoDB) monolog/monolog suggests installing rollbar/rollbar (Permit sending log messages to Rollbar) monolog/monolog suggests installing php-console/php-console (Permit sending log messages to Google Chrome) google/apiclient suggests installing tedivm/stash (For caching certs and tokens (using Google_Client::setCache)) Writing lock file Generating autoload files 2 packages you are using are looking for funding. Utilise the `composer fund` command to notice out more!        

Creating Google_Client class

The form Google_Client is used for authority of a client and set scopes such as read-simply, file admission, etc.
If y'all want to upload files then your scope must be set to Google_Service_Drive::DRIVE which internally points to URL https://www.googleapis.com/auth/drive.

Hither is how the class looks google-bulldoze.php.

<?php require __DIR__ . '/vendor/autoload.php';   /**     * Returns an authorized API client.     * @return Google_Client the authorized customer object     */  role getClient() {     $customer = new Google_Client();      $customer->setApplicationName('Google Drive API PHP Quickstart');     $client->setRedirectUri('http://localhost/test-examples/php/google-bulldoze-api/oauth2callback.php');      $client->setScopes(Google_Service_Drive::DRIVE);     $client->setAuthConfig('credentials.json');     $client->setAccessType('offline');     $client->setPrompt('select_account consent');      // Load previously authorized token from a file, if information technology exists.     // The file token.json stores the user'southward access and refresh tokens, and is     // created automatically when the authorization menstruation completes for the first     // time.     $tokenPath = 'token.json';     if (file_exists($tokenPath)) {         $accessToken = json_decode(file_get_contents($tokenPath), truthful);         $client->setAccessToken($accessToken);     }      // If there is no previous token or information technology's expired.     if ($customer->isAccessTokenExpired()) {         // Refresh the token if possible, else fetch a new one.         if ($client->getRefreshToken()) {             $client->fetchAccessTokenWithRefreshToken($customer->getRefreshToken());         } else {             // Asking authorization from the user.             $authUrl = $customer->createAuthUrl();             printf("Open the post-obit link in your browser:\n%southward\n", $authUrl);             impress 'Enter verification code: ';             $authCode = trim(fgets(STDIN));              // Exchange authorization lawmaking for an admission token.             $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);             $client->setAccessToken($accessToken);              // Check to see if in that location was an mistake.             if (array_key_exists('error', $accessToken)) {                 throw new Exception(join(', ', $accessToken));             }         }         // Salvage the token to a file.         if (!file_exists(dirname($tokenPath))) {             mkdir(dirname($tokenPath), 0700, true);         }         file_put_contents($tokenPath, json_encode($client->getAccessToken()));     }     return $client; }  // Get the API client and construct the service object. $client = getClient();        

In order to access the files from the cloud, you have to create a verification lawmaking.

Generating Access Token

Become to the root project and open terminal and type below command.

php google-drive.php        

This volition brandish a URL when clicked open in your browser and asks you lot to log in and authorize this request. After client hallmark, you will be prompted with verification lawmaking and you have to paste information technology here.

Upload File to Drive using HTML form

Let'south try to upload a file into google bulldoze using the class method.

form.php

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-viii">     <meta proper name="viewport" content="width=device-width, initial-calibration=i.0">     <title>File Upload</title> </head> <body>     <h2>PHP Google Drive Api </h2>     <a href="submit.php?list_files_and_folders=1">Click hither to list all files and folders</a>      <h2>File Upload</h2>     <form action="submit.php" method="post" enctype="multipart/course-data" >         <label for="">Cull File</label>         <input type="file" name="file" >                  <input type="submit" proper noun="submit" value="submit" >     </class> </body> </html>        

submit.php

Backend code for file upload.

In oauth2callback.php

<?php echo "<pre>"; print_r($_GET);
