Đọc thư từ Gmail, bằng PHP, sử dụng API Gmail

Question

Tôi đã không tải mã nguồn Gmail API mới từ thư viện ứng dụng khách PHP của Google.

tôi inititalized các dịch vụ sử dụng:

set_include_path("./google-api-php-client-master/src/".PATH_SEPARATOR.get_include_path()); 

require_once 'Google/Client.php'; 
require_once 'Google/Service/Gmail.php'; 

$client = new Google_Client(); 
$client->setClientId($this->config->item('gmailapi_clientid')); 
$client->setClientSecret($this->config->item('gmailapi_clientsecret')); 
$client->setRedirectUri(base_url('auth')); 
$client->addScope('email'); 
//$client->addScope('profile');  
$client->addScope('https://mail.google.com');   
$client->setAccessType('offline'); 

$gmailService = new Google_Service_Gmail($client); 

Tôi nên làm gì tiếp theo? Làm cách nào để đọc thư Gmail bằng Gmail API thư viện PHP?

Answer 1

Tôi muốn bắt đầu ở đây: https://developers.google.com/gmail/api/v1/reference/users/messages/list và https://developers.google.com/gmail/api/v1/reference/users/messages/get

lưu ý rằng khi bạn nhận được một danh sách các thông điệp chỉ ID của những thông điệp được trả về sau đó bạn sử dụng ID với method get để thực sự có được nội dung tin nhắn:

Answer 2

vì lợi ích của cuộc biểu tình, bạn có thể làm một cái gì đó như thế này:

 $optParams = []; 
     $optParams['maxResults'] = 5; // Return Only 5 Messages 
     $optParams['labelIds'] = 'INBOX'; // Only show messages in Inbox 
     $messages = $service->users_messages->listUsersMessages('me',$optParams); 
     $list = $messages->getMessages(); 
     $messageId = $list[0]->getId(); // Grab first Message 


     $optParamsGet = []; 
     $optParamsGet['format'] = 'full'; // Display message in payload 
     $message = $service->users_messages->get('me',$messageId,$optParamsGet); 
     $messagePayload = $message->getPayload(); 
     $headers = $message->getPayload()->getHeaders(); 
     $parts = $message->getPayload()->getParts(); 

     $body = $parts[0]['body']; 
     $rawData = $body->data; 
     $sanitizedData = strtr($rawData,'-_', '+/'); 
     $decodedMessage = base64_decode($sanitizedData); 

     var_dump($decodedMessage);

này có đầy đủ chức năng, bạn có thể sử dụng nó bởi vì nó hoạt động tốt.

session_start(); 
     $this->load->library('google'); 
     $client = new Google_Client(); 
     $client->setApplicationName('API Project'); 
     $client->setScopes(implode(' ', array(Google_Service_Gmail::GMAIL_READONLY))); 
     //Web Applicaion (json) 
     $client->setAuthConfigFile('key/client_secret_105219sfdf2456244-bi3lasgl0qbgu5hgedg9adsdfvqmds5c0rkll.apps.googleusercontent.com.json'); 

     $client->setAccessType('offline');  

     // Redirect the URL after OAuth 
     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 Access Toket is not set, show the OAuth URL 
     if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {

      $authUrl = $client->createAuthUrl(); 
     } 

     if ($client->getAccessToken()) { 

      $_SESSION['access_token'] = $client->getAccessToken(); 

      // Prepare the message in message/rfc822 
      try { 

       // The message needs to be encoded in Base64URL 

       $service = new Google_Service_Gmail($client); 

       $optParams = []; 
       $optParams['maxResults'] = 5; // Return Only 5 Messages 
       $optParams['labelIds'] = 'INBOX'; // Only show messages in Inbox 
       $messages = $service->users_messages->listUsersMessages('me',$optParams); 
       $list = $messages->getMessages(); 
       $messageId = $list[0]->getId(); // Grab first Message 


       $optParamsGet = []; 
       $optParamsGet['format'] = 'full'; // Display message in payload 
       $message = $service->users_messages->get('me',$messageId,$optParamsGet); 
       $messagePayload = $message->getPayload(); 
       $headers = $message->getPayload()->getHeaders(); 
       $parts = $message->getPayload()->getParts(); 

       $body = $parts[0]['body']; 
       $rawData = $body->data; 
       $sanitizedData = strtr($rawData,'-_', '+/'); 
       $decodedMessage = base64_decode($sanitizedData); 

     var_dump($decodedMessage); 

      } catch (Exception $e) { 
       print($e->getMessage()); 
       unset($_SESSION['access_token']); 
      } 

     } 

    // If there is no access token, there will show url 
    if (isset ($authUrl)) { 
      echo $authUrl; 
     }
