Google Spreadsheets API with PHP – Fatal error: Uncaught exception - php

Question

I'm trying to get started with the google SpreadSheet API. I know there are a bunch of other languages but PHP is the only one I'm vaguely competent in. I keep falling at the first hurdle and getting:
Fatal error: Uncaught exception 'Google\Spreadsheet\Exception' in
/Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/ServiceRequestFactory.php:48
Stack trace: #0 /Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/SpreadsheetService.php(37):
Google\Spreadsheet\ServiceRequestFactory::getInstance()
#1 /Users/djave/Google Drive/Sites/practise/gdata/index.php(32): Google\Spreadsheet\SpreadsheetService->getSpreadsheets()
#2 {main} thrown in /Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/ServiceRequestFactory.php on line 48
How this happens:
Step 1 Download and add the folder google-api-php-client
Next, fiddle with the code until it works
set_include_path('lib/');
require_once 'lib/Google/Client.php';
require_once 'lib/Google/Service/Books.php';
$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
$client->setDeveloperKey("-------------------------------------");
$service = new Google_Service_Books($client);
$optParams = array('filter' => 'free-ebooks');
$results = $service->volumes->listVolumes('Henry David Thoreau', $optParams);
foreach ($results as $item) {
echo $item['volumeInfo']['title'], "<br /> \n";
}
Result: prints out a list of books
Step 2 Download and install php-google-spreadsheet-client
First off I copy the example exactly below what I have, then include all the right files until it can find everything:
set_include_path('lib/');
require_once 'lib/Google/Client.php';
require_once 'lib/Google/Service/Books.php';
require_once 'lib/Google/Spreadsheet/SpreadsheetService.php';
require_once 'lib/Google/Spreadsheet/ServiceRequestFactory.php';
require_once 'lib/Google/Spreadsheet/Exception.php';
$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
$client->setDeveloperKey("-------------------------------------");
$service = new Google_Service_Books($client);
$optParams = array('filter' => 'free-ebooks');
$results = $service->volumes->listVolumes('Henry David Thoreau', $optParams);
foreach ($results as $item) {
echo $item['volumeInfo']['title'], "<br /> \n";
}
$spreadsheetService = new Google\Spreadsheet\SpreadsheetService();
$spreadsheetFeed = $spreadsheetService->getSpreadsheets();
$spreadsheet = $spreadsheetFeed->getByTitle('MySpreadsheet');
$worksheetFeed = $spreadsheet->getWorksheets();
But I just get
Fatal error: Uncaught exception 'Google\Spreadsheet\Exception' in /Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/ServiceRequestFactory.php:48 Stack trace: #0 /Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/SpreadsheetService.php(37): Google\Spreadsheet\ServiceRequestFactory::getInstance() #1 /Users/djave/Google Drive/Sites/practise/gdata/index.php(23): Google\Spreadsheet\SpreadsheetService->getSpreadsheets() #2 {main} thrown in /Users/djave/Google Drive/Sites/practise/gdata/lib/Google/Spreadsheet/ServiceRequestFactory.php on line 48
I'm doing something really stupid, right? Thanks for any help

Answer 1

Looks like you've forgotten to bootstrap the lib first: https://github.com/asimlqt/php-google-spreadsheet-client#bootstrapping
require 'vendor/autoload.php';
use Google\Spreadsheet\DefaultServiceRequest;
use Google\Spreadsheet\ServiceRequestFactory;
$serviceRequest = new DefaultServiceRequest($accessToken);
ServiceRequestFactory::setInstance($serviceRequest);

Answer 2

Give edit permission to "client_email" field value in client_secret.json file by opening the actual spreadsheet, refer image.
