(PHP Extension) GMail SMTP Send using Previously Obtained OAuth2 Access TokenDemonstrates how to send email using GMail and OAuth2 authentication. This example assumes an OAuth2 access token was previously obtained.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // See Get GMail SMTP Access Token // for sample code showing how to obtain a GMail SMTP access token for desktop apps. // In this example, our access token was previously saved to the following file which contains JSON like this: // { // "access_token": "ya39.Ci-XA_C5bGgRDC3UaD-h0_NeL-DVIQnI2gHtBBBHkZzrwlARkwX6R3O0PCDEzRlfaQ", // "token_type": "Bearer", // "expires_in": 3600, // "refresh_token": "1/r_2c_7jddspcdfesrrfKqfXtqo08D6Q-gUU0DsdfVMsx0c" // } // $json = new CkJsonObject(); $success = $json->LoadFile('qa_data/tokens/_gmailSmtp.json'); if ($success != true) { print 'Failed to load GMail access token file.' . "\n"; exit; } $accessToken = $json->stringOf('access_token'); $mailman = new CkMailMan(); // Set the properties for the GMail SMTP server: $mailman->put_SmtpHost('smtp.gmail.com'); $mailman->put_SmtpPort(587); $mailman->put_StartTLS(true); // The SMTP username should be the GMail address of the user's account that authorized your app to send email. $mailman->put_SmtpUsername('chilkat.support@gmail.com'); $mailman->put_OAuth2AccessToken($accessToken); // Create a new email object $email = new CkEmail(); $email->put_Subject('This is a test'); $email->put_Body('This is a test'); $email->put_From('Chilkat <chilkat.support@gmail.com>'); $email->AddTo('Chilkat Admin','admin@chilkatsoft.com'); // To add more recipients, call AddTo, AddCC, or AddBcc once per recipient. // Call SendEmail to connect to the SMTP server and send. // The connection (i.e. session) to the SMTP server remains // open so that subsequent SendEmail calls may use the // same connection. $success = $mailman->SendEmail($email); if ($success != true) { print $mailman->lastErrorText() . "\n"; exit; } // You may close the connection here. If the connection is kept open, // the next call to mailman.SendEmail will continue using the already-established connection // (and automatically re-connect if needed). $success = $mailman->CloseSmtpConnection(); if ($success != true) { print 'Connection to SMTP server not closed cleanly.' . "\n"; } print 'Email Sent via GMail with OAuth2 authentication.' . "\n"; ?> |
