我应该将邮件服务从旧项目替换为GMail。但是，该项目使用的是PHP，并且google文档页面中尚未提供PHP代码的文档。我想测试发送一个带有简单邮件正文的电子邮件，这里是代码：
require_once __DIR__."/google-api-php-client-2.2.1/vendor/autoload.php";
define("APPLICATION_NAME", "Gmail API PHP Quickstart");
define("CREDENTIALS_PATH", "~/.credentials/gmail-php-quickstart.json");
define("CLIENT_SECRET_PATH", __DIR__."/client_secret.json");
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/gmail-php-quickstart.json
define('SCOPES', implode(' ', array(
Google_Service_Gmail::GMAIL_READONLY)
));
date_default_timezone_set('America/New_York'); // Prevent DateTime tz exception
/*
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(APPLICATION_NAME);
$client->setScopes(SCOPES);
$client->setAuthConfig(CLIENT_SECRET_PATH);
$client->setAccessType('offline');
// Load previously authorized credentials from a file.
$credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);
if (file_exists($credentialsPath)) {
$accessToken = json_decode(file_get_contents($credentialsPath), true);
}
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);
// Store the credentials to disk.
if(!file_exists(dirname($credentialsPath))) {
mkdir(dirname($credentialsPath), 0700, true);
}
file_put_contents($credentialsPath, json_encode($accessToken));
printf("Credentials saved to %s\n", $credentialsPath);
}
$client->setAccessToken($accessToken);
// Refresh the token if it's expired.
if ($client->isAccessTokenExpired()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
}
return $client;
}
/**
* Expands the home directory alias '~' to the full path.
* @param string $path the path to expand.
* @return string the expanded path.
*/
function expandHomeDirectory($path) {
$homeDirectory = getenv('HOME');
if (empty($homeDirectory)) {
$homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
}
return str_replace('~', realpath($homeDirectory), $path);
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Gmail($client);
// Print the labels in the user's account.
$user = 'me';
$message = new Google_Service_Gmail_Message();
$messagePart = new Google_Service_Gmail_MessagePart();
$messagePartBody = new Google_Service_Gmail_MessagePartBody();
$messagePartHeader = new Google_Service_Gmail_MessagePartHeader();
$messagePartBody->setData("TEST BY FAROUK");
$messagePart->setHeader($messagePartHeader);
$messagePart->setBody($messagePartBody);
$message->setPayLoad($messagePart);
$service->users_messages->send($user, $message, null);
问题出在这一部分，尚未完成：
$user = 'me';
$message = new Google_Service_Gmail_Message();
$messagePart = new Google_Service_Gmail_MessagePart();
$messagePartBody = new Google_Service_Gmail_MessagePartBody();
$messagePartHeader = new Google_Service_Gmail_MessagePartHeader();
$messagePartBody->setData("TEST BY ME");
$messagePart->setHeader($messagePartHeader);
$messagePart->setBody($messagePartBody);
$message->setPayLoad($messagePart);
$service->users_messages->send($user, $message, null);
我知道我必须创建这些类的对象但是，我不知道我应该使用它们的setter在参数中设置什么类型的数据。
请给出一个简单的代码来发送“Hello world！”到foo@gmail.com这样的电子邮件地址。谢谢！

此工作示例使用的是服务帐户，请根据您的需要进行调整：
$user_to_impersonate = "email_to_impersonate@yourdomain.com";
putenv("GOOGLE_APPLICATION_CREDENTIALS=google-api-php-client/service-account-credentials.json");
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setSubject($user_to_impersonate);
$client->setApplicationName("My Mailer");
$client->setScopes(["https://www.googleapis.com/auth/gmail.compose"]);
$service = new Google_Service_Gmail($client);
// Process data
try {
$strSubject = "Set the email subject here";
$strRawMessage = "From: Me<myemail@mydomain.com>\r\n";
$strRawMessage .= "To: Foo<foo@gmail.com>\r\n";
$strRawMessage .= "CC: Bar<bar@gmail.com>\r\n";
$strRawMessage .= "Subject: =?utf-8?B?" . base64_encode($strSubject) . "?=\r\n";
$strRawMessage .= "MIME-Version: 1.0\r\n";
$strRawMessage .= "Content-Type: text/html; charset=utf-8\r\n";
$strRawMessage .= "Content-Transfer-Encoding: base64" . "\r\n\r\n";
$strRawMessage .= "Hello World!" . "\r\n";
// The message needs to be encoded in Base64URL
$mime = rtrim(strtr(base64_encode($strRawMessage), '+/', '-_'), '=');
$msg = new Google_Service_Gmail_Message();
$msg->setRaw($mime);
//The special value **me** can be used to indicate the authenticated user.
$service->users_messages->send("me", $msg);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
希望这有助于您入门
