Unable to list the events and received error 404 - php

Question

I tried this code, but it doesn't show any result and I checked my error log it says 404 not found.
I tried using another method it say missing scope.
<?php
session_start();
error_reporting(E_ALL);
require_once "Google/Client.php";
require_once "Google/Service/Calendar.php";
$client = new Google_Client();
/************************************************
ATTENTION: Fill in these values! Make sure
the redirect URI is to this page, e.g:
http://localhost:8080/user-example.php
************************************************/
$client_id = '';
$client_secret = '';
$redirect_uri = 'http://localhost/listgoogleuser.php';
/************************************************
Make an API request on behalf of a user. In
this case we need to have a valid OAuth 2.0
token for the user, so we need to send them
through a login flow. To do this we need some
information from our API console project.
************************************************/
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/calendar");
$service = new Google_Service_Calendar($client);
/************************************************
If we're logging out we just need to clear our
local access token in this case
************************************************/
if (isset($_REQUEST['logout'])) {
unset($_SESSION['access_token']);
}
/************************************************
If we have a code back from the OAuth 2.0 flow,
we need to exchange that with the authenticate()
function. We store the resultant access token
bundle in the session, and redirect to ourself.
************************************************/
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['access_token'] = $client->getAccessToken();
$redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
/************************************************
If we have an access token, we can make
requests, else we generate an authentication URL.
************************************************/
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$client->setAccessToken($_SESSION['access_token']);
} else {
$authUrl = $client->createAuthUrl();
}
$events = $service->events->listEvents('URL HERE');
foreach($events['items'] as $datauser){
echo $datauser['summary'];
}
?>

Answer 1

I was having the same issues, though for me every method I was trying was ending up not working so to kill two birds with one stone I started over and used the code you provided above. I removed these lines of code:
$events = $service->events->listEvents('URL HERE');
foreach($events['items'] as $datauser){
echo $datauser['summary'];
}
And added this at the very end and I was able to get a response.
<div class="box">
<div class="request">
<?php if (isset($authUrl)): ?>
<a class='login' href='<?php echo $authUrl; ?>'>Connect Me!</a>
<?php else: ?>
<?
$calendarList = $service->calendarList->listCalendarList();
while(true) {
foreach ($calendarList->getItems() as $calendarListEntry) {
echo $calendarListEntry->getSummary()." | ".$calendarListEntry->getId()."<br/>";
}
$pageToken = $calendarList->getNextPageToken();
if ($pageToken) {
$optParams = array('pageToken' => $pageToken);
$calendarList = $service->calendarList->listCalendarList($optParams);
} else {
break;
}
}
?>
<a class='logout' href='?logout'>Logout</a>
<?php endif ?>
</div>
<?php if (isset($short)): ?>
<div class="shortened">
<?php var_dump($short); ?>
</div>
<?php endif ?>
</div>
Also at the top of your page you call $client = new Google_Client(); twice.
