How to fetch gmail in php without using imap? - php

I have used imap for fetching gmail using php. Is there any other way to fetch gmails using php without using imap?

You can use the gmail api to access a users gmail account. You will need to authenticate the user using Oauth2 rather than using the login and password you are probably using on the imap server.
Google has a quick start which can be found here

Google API Quickstart

I've run into the problem with Google API quickstart. I couldn't verify the token because it says that the token format is invalid. The strangest part was that I was able to make it run a few months ago on another project, but now I can't do anything.
My quickstart.php look as:
<?php
require __DIR__ . '/vendor/autoload.php';
if (php_sapi_name() != 'cli') {
throw new Exception('This application must be run on the command line.');
}
/**
* Returns an authorized API client.
* #return Google_Client the authorized client object
*/
function getClient()
{
$client = new Google_Client();
$client->setApplicationName('Google Sheets API');
$client->setScopes(Google_Service_Sheets::SPREADSHEETS);
$client->setAuthConfig('credentials.json');
$client->setAccessType('offline');
$client->setPrompt('select_account consent');
// Load previously authorized token from a file, if it exists.
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
$tokenPath = 'token.json';
if (file_exists($tokenPath)) {
$accessToken = json_decode(file_get_contents($tokenPath), true);
$client->setAccessToken($accessToken);
}
// If there is no previous token or it's expired.
if ($client->isAccessTokenExpired()) {
// Refresh the token if possible, else fetch a new one.
if ($client->getRefreshToken()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
} else {
// Request authorization from the user.
$authUrl = $client->createAuthUrl();
printf("Open the following link in your browser:\n%s\n", $authUrl);
print 'Enter verification code: ';
$authCode = trim(fgets(STDIN));
// Exchange authorization code for an access token.
$accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
$client->setAccessToken($accessToken);
// Check to see if there was an error.
if (array_key_exists('error', $accessToken)) {
throw new Exception(join(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($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();
$service = new Google_Service_Sheets($client);
// Prints the names and majors of students in a sample spreadsheet:
// https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
$spreadsheetId = '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms';
$range = 'Class Data!A2:E';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();
if (empty($values)) {
print "No data found.\n";
} else {
print "Name, Major:\n";
foreach ($values as $row) {
// Print columns A and E, which correspond to indices 0 and 4.
printf("%s, %s\n", $row[0], $row[4]);
}
}
When I attempt to enter the token it returns following error
Fatal error: Uncaught InvalidArgumentException: Invalid token format in ..\vendor\google\apiclient\src\Google\Client.php:469
Stack trace:
#0 ..\quickstart.php(45): Google_Client->setAccessToken()
#1 ..\quickstart.php(63): getClient()
#2 {main}
thrown in ..\vendor\google\apiclient\src\Google\Client.php on line 469
I've tried to append for $authCode token manually, but it didn't work.
So it literally was my mistake, our front engine changed the link "a bit" so it wasn't be able to be verified. As I've changed to a random domain and copied the token everything worked well.

I am trying to implement this code as its written in here:
https://developers.google.com/drive/api/v3/quickstart/php

Error sending test message to Cloud PubSub returning 403 authorization error

I am trying to setup a push notification as documented in Gmail API Users: watch, but always getting 403 error i.e
Error sending test message to Cloud PubSub .... User not authorized to
perform this action
. I am using Google PHP library and follow the quickstart.php to initiate this action. Here is my script as follows:
require __DIR__ . '/vendor/autoload.php';
if (php_sapi_name() != 'cli') {
throw new Exception('This application must be run on the command line.');
}

$client->setAuthConfig('credentials.json');
$client->setIncludeGrantedScopes(true);

$msg = $service->users->watch('me', $watchreq);
Any help in this regard will be appreciated.
You can use this sample code to test permissions for a topic, because the error message states that the service account does not have the necessary permissions to perform this action:
Testing permissions
use Google\Cloud\PubSub\PubSubClient;
/**
* Prints the permissions of a topic.
*
* #param string $projectId The Google project ID.
* #param string $topicName The Pub/Sub topic name.
*/
function test_topic_permissions($projectId, $topicName)
{
$pubsub = new PubSubClient([
'projectId' => $projectId,
]);
$topic = $pubsub->topic($topicName);
$permissions = $topic->iam()->testPermissions([
'pubsub.topics.attachSubscription',
'pubsub.topics.publish',
'pubsub.topics.update'
]);
foreach ($permissions as $permission) {
printf('Permission: %s' . PHP_EOL, $permission);
}
}
Then, just grant to the service account the necessary permissions:

Is there any error to my code? Is there any debug console allowing me to find the reason?

Sorry for my important mistake, I didn't enable the APIs and Services from Google console.

Google Calendar API PHP skip the client side authentication and turn everything into a web application instead of command line one

I am creating a code that must add, update and delete event to google calendar I have the email address of the user to be added.
How to have auto client side authentication( confirm authentication by itself and get verification code)?
And
Turn to a web application instead of command line?
require_once 'vendor/autoload.php';

Cant get the tutorial to implement this....
You cant. In order to access private user data (like a users calendar) your application must first be authenticated by said user.
Possible solution: Have the user authentication it the first time (will require the HTTP webpage to be displayed). You will be given a refresh token. Save the refresh token. Your automated script can then use the refresh token to gain a new access token and update the calendar when ever it likes (no web display needed).
