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 :
- Been to the Google APIs Console and :
- Enabled “Drive API” and “Drive SDK” under ‘Services’;
- 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”;
- Downloaded the “Google API PHP Client Library”;
- Opened the Google Drive document (spreadsheet) and clicked on “Share” to get the document’s ‘key’;
- 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).
There is also a much easier, but less clean solution, if you don’t want to bother with the API or Google Authentication.
- Go to your Spreadsheet in Google Drive.
- Go to files -> Publish on the Web
- Select the right worksheet and make sure to enable the checkbox always update.
- Still in the same box 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：
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.
Answer：
I created a sample project that uses a service account to authenticate against Google Spreadsheets in order to access to the contents of a spreadsheet.
Have a look at the README at https://github.com/juampynr/google-spreadsheet-reader.
Answer：
You need to use oauth, if you don’t google will only allow you to make a few requests.
If all you want to do is read data out of a google spreadsheet or write data into it then you can just use the spreadsheet api. Check out php-google-spreadsheet-client.
Answer：
If you want you own file to be read you need a service account instead of a “Client ID for web applications”. I’ve been battling this problem myself for way to long and this brought me the sollution:
