How do I read a Google Drive Spreadsheet in PHP?

Question

All I'm trying to do is read a Google Spreadsheet from a web site. I've read and re-read the Google Drive API docs and everything Google Drive PHP on Stack Overflow and I still can't get to the end zone.

Here's what I've done :

1. Been to the Google APIs Console and :
   1. Enabled "Drive API" and "Drive SDK" under 'Services';
   2. Created an OAuth 2.0 client ID under 'API Access'. Under "Client ID for web applications", the console gave me "Client ID", "Email address", "Client secret", "Redirect URIs" and "JavaScript origins";
2. Downloaded the "Google API PHP Client Library";
3. Opened the Google Drive document (spreadsheet) and clicked on "Share" to get the document's 'key';
4. Set up the following code :

<?php  session_start();  require_once 'lib/gapi/Google_Client.php';  require_once 'lib/gapi/contrib/Google_DriveService.php';   define( 'GDRIVE_CLIENT_ID', '<API Console - API Access - Client ID>' );  define( 'GDRIVE_CLIENT_SECRET', '<API Console - API Access - Client secret>' );  define( 'GDRIVE_REDIRECT_URIS', '<API Console - API Access - Redirect URIs>' );   define( 'GDRIVE_SCOPE_01', 'h t t p s://www.googleapis.com/auth/drive' );  define( 'GDRIVE_SCOPE_02', 'h t t p s://www.googleapis.com/auth/drive.apps.readonly' );  define( 'GDRIVE_SCOPE_03', 'h t t p s://www.googleapis.com/auth/drive.file' );  define( 'GDRIVE_SCOPE_04', 'h t t p s://www.googleapis.com/auth/drive.metadata.readonly' );  define( 'GDRIVE_SCOPE_05', 'h t t p s://www.googleapis.com/auth/drive.readonly' );  define( 'GDRIVE_FILE_KEY', '<'key' given from 'sharing' document>' );   $client = new Google_Client();  $client->setClientId( GDRIVE_CLIENT_ID );  $client->setClientSecret( GDRIVE_CLIENT_SECRET );  $client->setRedirectUri( GDRIVE_REDIRECT_URIS );  $client->setScopes( array( GDRIVE_SCOPE_01, GDRIVE_SCOPE_02, GDRIVE_SCOPE_03, GDRIVE_SCOPE_04, GDRIVE_SCOPE_05 ) );   try {    $file = $service->files->get( GDRIVE_FILE_KEY );    echo "Title: ", $file->getTitle();    echo "Description: ", $file->getDescription();    echo "MIME type: ", $file->getMimeType();  } catch (Exception $e) {    echo "An error occurred: ", $e->getMessage();  }  ?>  

All runs fine (no errors anyway) until the $service->files->get( GDRIVE_FILE_KEY ) call which triggers the exception:

An error occurred: Error calling GET https://www.googleapis.com/drive/v2/files: (403) Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.

What am I doing wrong? I've pulled my hair out (well, what was left).

Answer 1

There is also a much easier, but less clean solution, if you don't want to bother with the API or Google Authentication.

1. Go to your Spreadsheet in Google Drive.
2. Go to File -> Publish to the Web
3. In the Publish to the web dialog you can get a .csv Link to your spreadsheet.

You can now access the contents like any other csv File on the Web. Here is some sample code:

$spreadsheet_url="https://docs.google.com/spreadsheet/pub?key=<somecode>&single=true&gid=0&output=csv";  if(!ini_set('default_socket_timeout', 15)) echo "<!-- unable to change socket timeout -->";  if (($handle = fopen($spreadsheet_url, "r")) !== FALSE) {     while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {         $spreadsheet_data[] = $data;     }     fclose($handle); } else     die("Problem reading csv"); 

Answer 2

Please check the Google Drive PHP Quickstart. You have not actually authorized your client. Starting from $authUrl = $client->createAuthUrl();

All Google Drive requests need authorization of some kind.
