Question

我正在尝试获取给定搜索的电子邮件数量（单独阅读和未读）。我已经读过labels.get（）函数可以解决问题，但我不知道如何使用它。这是我必须检测的代码，如果我对给定的发件人有少于或多于100的结果。

      require_once '../../vendor/autoload.php';
      session_start();
      $client = new Google_Client();
      $client->setAuthConfigFile('../../client_secrets.json');
      $client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
      $client->addScope(Google_Service_Gmail::GMAIL_READONLY);
      $client->setAccessType("offline");
      $client->setApprovalPrompt('force');
      $client->setAccessToken($_SESSION['token']);
      $service = new Google_Service_Gmail($client);

      $sender = array();
      $sender[] = 'sender1@email.com';
      $sender[] = 'sender2@email.com';
      $sender[] = 'sender3@email.com';

      function countfrom($service, $userId, $expeditor) {
            try
            {
              unset($optParamsamz);
              $optParamsamz = [];
              $optParamsamz['maxResults'] = 100; // Return Only 5 Messages
              $optParamsamz['q'] = "From: '".$expeditor."'  "; 
              $messagesamz = $service->users_messages->listUsersMessages('me',$optParamsamz);
              $listamz = $messagesamz->getMessages();
              echo sizeof($listamz);

          }
         catch (Exception $e)
            {
              print 'An error occurred: ' . $e->getMessage();
            }

          }

foreach ($sender as $key => $value)
            {
             echo $value .': ';
             countfrom($service,$_SESSION['emaile'],$value)  ;
             echo '<br/>';
            }

我尝试了一种似乎更接近我正在寻找的新解决方案。现在的问题来自Google，它为结果评估返回了一些奇数：

<?
  require_once '../../vendor/autoload.php';
  session_start();
  $client = new Google_Client();
  $client->setAuthConfigFile('../../client_secrets.json');
  $client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
  $client->addScope(Google_Service_Gmail::GMAIL_READONLY);
  $client->setAccessType("offline");
  $client->setApprovalPrompt('force');
  $client->setAccessToken($_SESSION['token']);
  $service = new Google_Service_Gmail($client);

  $sender_array[] = 'sender1@sender.com';
  $sender_array[] = 'sender2@sender.com';
  $sender_array[] = 'sender3@sender.com';
  $sender_array[] = 'sender4@sender.com';

  foreach ($sender_array as $key => $expeditor)
  {

    $optParamsamz1['q'] = "From: '".$expeditor."' is:read  "; 
    $optParamsamz2['q'] = "From: '".$expeditor."'   "; 

    echo $expeditor.": ".$service->users_messages->listUsersMessages('me',$optParamsamz1)->getResultSizeEstimate() . "
                       ".$service->users_messages->listUsersMessages('me',$optParamsamz2)->getResultSizeEstimate(); 
    echo "<br>";
  }

我担心，

labels.get()在这个用例中没有任何帮助。它仅适用于标签，因此您可以从例如标签读取/未读取INBOX或CHAT很容易，但是如果您希望从中获取所有已读取/未读取内容，则无济于事从example@gmail.com发送的所有邮件。

另一种解决方案相当便宜：

使用查询+ AND is:unread列出邮件，使用相同的查询+列出第二个邮件 AND -is:unread。
如果回复包含nextPageToken，则您有100多个已读/未读。如果它不包含nextPageToken，则有response.messages.length条已读/未读邮件。

示例

请求未读

q = from:info@berniesanders.com AND is:unread GET https://www.googleapis.com/gmail/v1/users/me/messages?q=from%3Ainfo%40berniesanders.com+AND+is%3Aunread&access_token={YOUR_API_KEY}

<强>响应

{ "messages": [ { "id": "1523144d6e3feb2e", "threadId": "1523144d6e3feb2e" }, { "id": "15227d879ccb601f", "threadId": "15227d879ccb601f" }, ... } // No nextPageToken => response.messages.length unread = 22 unread

请求未读

q = from:info@berniesanders.com AND -is:unread GET https://www.googleapis.com/gmail/v1/users/me/messages?q=from%3Ainfo%40berniesanders.com+AND+-is%3Aunread&access_token={YOUR_API_KEY}

<强>响应

{ "messages": [ { "id": "1522d4af39d7eec6", "threadId": "1522d4af39d7eec6" }, { "id": "1521d6f3dbeaf886", "threadId": "1521d6f3dbeaf886" }, ... "nextPageToken": "32436546446" } // nextPageToken in response => 100+ read

您可以更进一步，继续使用nextPageToken列出，直到响应中没有nextPageToken，然后将所有结果添加到一起，但这可能会导致速度变慢或效率低下为您的用例。
