我正在创建一个基于网络的邮件客户端，该客户端使用Google OAuth2 API支持Google帐户，登录工作正常，并且在首次登录时询问了Gmail的权限，但我不明白如何从用户帐户获取邮件。根据Google Gmail API文档，我正在创建一个类来使用这些API，但我不明白如何使用它。
class Gmail
{
/*
* Get list of Messages in user's mailbox.
* @param Google_Service_Gmail $service Authorized Gmail API instance.
* @param string $userId User's email address. The special value 'me'
* can be used to indicate the authenticated user.
* @return array Array of Messages.
*/
function listMessages($service, $userId) {
$pageToken = NULL;
$messages = array();
$opt_param = array();
do {
try {
if ($pageToken) {
$opt_param['pageToken'] = $pageToken;
}
$messagesResponse = $service->users_messages->listUsersMessages($userId, $opt_param);
if ($messagesResponse->getMessages()) {
$messages = array_merge($messages, $messagesResponse->getMessages());
$pageToken = $messagesResponse->getNextPageToken();
}
} catch (Exception $e) {
print 'An error occurred: ' . $e->getMessage();
}
} while ($pageToken);
foreach ($messages as $message) {
print 'Message with ID: ' . $message->getId() . '<br/>';
}
return $messages;
}
function getMessage($service, $userId, $messageId) {
try {
$message = $service->users_messages->get($userId, $messageId);
print 'Message with ID: ' . $message->getId() . ' retrieved.';
return $message;
} catch (Exception $e) {
print 'An error occurred: ' . $e->getMessage();
}
}
}
在我的模板中，我已将类分配给变量$Gmail并开始使用以下：
$gmailMessages = $Gmail->listMessages(GOOGLE_AUTH_API_KEY, $user_inbox["Profile_Email"]);
但我认为这不是正确的方法..我必须向函数传递什么？谢谢。
编辑：我已经将Google Api PHP客户端包含在我的项目中。
编辑：已解决，请参阅此处的解决方案
已解决，我忘记设置并调用$client，现在我的函数是：
function listMessages($userId) {
$client_id = API_CLIENT_ID;
$client_secret = API_SECRET;
$redirect_uri = API_REDIRECT_URL;
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://mail.google.com/ https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile ");
$client->setAccessType("offline");
$service = new Google_Service_Gmail($client);
$pageToken = NULL;
$messages = array();
$opt_param = array();
do {
try {
if ($pageToken) {
$opt_param['pageToken'] = $pageToken;
}
$messagesResponse = $service->users_messages->listUsersMessages($userId, $opt_param);
if ($messagesResponse->getMessages()) {
$messages = array_merge($messages, $messagesResponse->getMessages());
$pageToken = $messagesResponse->getNextPageToken();
}
} catch (Exception $e) {
print 'An error occurred: ' . $e->getMessage();
}
} while ($pageToken);
foreach ($messages as $message) {
print 'Message with ID: ' . $message->getId() . '<br/>';
}
return $messages;
}
