[英]Using GMAIL API with Symfony4
我想在我的symfony4网站上使用Gmail API 。 目标是通过cron定期执行命令,该命令将提取所有未读的电子邮件,获取内容并处理某些内容,然后将其标记为已读。
我目前有(虽然官方文档 ):
来自symfony的工作命令(app:upload-from-unread-emails),具有以下代码:
$client = new \\Google_Client(); $client->setApplicationName('Gmail API PHP Quickstart'); $client->addScope(\\Google_Service_Gmail::GMAIL_READONLY); $client->setAuthConfig('credentials.json'); $client->setAccessType('offline'); $client->setPrompt('select_account consent'); $gmail = new \\Google_Service_Gmail($client); $list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 1000]); while ($list->getMessages() != null) { foreach ($list->getMessages() as $mlist) { $message_id = $mlist->id; var_dump($message_id); } if ($list->getNextPageToken() != null) { $pageToken = $list->getNextPageToken(); $list = $gmail->users_messages->listUsersMessages('me', ['pageToken' => $pageToken, 'maxResults' => 1000]); } else { break; } }
我是否在进行身份验证的正确道路上? 我应该在哪里将credential.json放在symfony中?
我应该在哪里将credential.json放在symfony中?
我认为此文件的最佳位置将是config
文件夹。 但是您可以设置任何路径(除非可能不在public
=中)。
假设此文件的路径为config/gmail/credentials.json
。 因此,下一步是在命令中获取文件路径。 为此,您需要从服务容器获取kernel.project_dir
参数,并将kernel.project_dir
和/config/gmail/credentials.json
连接在一起
要在命令中使用服务容器,您需要:
ContainerAwareInterface
ContainerAwareTrait
(用于$container
属性和setContainer
方法) ContainerInterface $container
中键入提示ContainerInterface $container
,调用parent::__construct
和setContainer($container)
-
// ...
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
use Symfony\Component\DependencyInjection\ContainerInterface;
class UploadFromUnreadEmailsCommand extends Command implements ContainerAwareInterface
{
use ContainerAwareTrait;
public function __construct(ContainerInterface $container)
{
parent::__construct();
$this->setContainer($container);
}
// ...
}
此外,您链接的文档还包含带有getClient函数的示例。 只需进行一些更改即可对其进行编辑:
private function getClient()
{
$projectDir = $this->container->getParameter('kernel.project_dir');
$credentialsFilePath = sprintf('%s/config/gmail/credentials.json', $projectDir);
$tokenFilePath = sprintf('%s/config/gmail/token.json', $projectDir);
// ...
}
在execute
方法中:
$client = $this->getClient();
$gmail = new \Google_Service_Gmail($client);
执行命令并遵循说明(生成令牌)。
完整的命令类:
<?php
namespace App\Command;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Style\SymfonyStyle;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
use Symfony\Component\DependencyInjection\ContainerInterface;
class UploadFromUnreadEmailsCommand extends Command implements ContainerAwareInterface
{
use ContainerAwareTrait;
protected static $defaultName = 'app:upload-from-unread-emails';
/**
* UploadFromUnreadEmailsCommand constructor.
* @param $container
*/
public function __construct(ContainerInterface $container)
{
parent::__construct();
$this->setContainer($container);
}
protected function configure()
{
$this
->setDescription('Add a short description for your command')
;
}
private function getClient()
{
$projectDir = $this->container->getParameter('kernel.project_dir');
$credentialsFilePath = sprintf('%s/config/gmail/credentials.json', $projectDir);
$tokenFilePath = sprintf('%s/config/gmail/token.json', $projectDir);
$client = new \Google_Client();
$client->setApplicationName('Gmail API PHP Quickstart');
$client->setScopes(\Google_Service_Gmail::GMAIL_READONLY);
$client->setAuthConfig($credentialsFilePath);
$client->setAccessType('offline');
$client->setPrompt('select_account consent');
// Load previously authorized token from a file, if it exists.
if (file_exists($tokenFilePath)) {
$accessToken = json_decode(file_get_contents($tokenFilePath), true);
$client->setAccessToken($accessToken);
}
// If there is no previous token or it's expired.
if ($client->isAccessTokenExpired()) {
// Refresh the token if possible, else fetch a new one.
if ($client->getRefreshToken()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
} 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);
$client->setAccessToken($accessToken);
// Check to see if there was an error.
if (array_key_exists('error', $accessToken)) {
throw new Exception(join(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($tokenFilePath))) {
mkdir(dirname($tokenFilePath), 0700, true);
}
file_put_contents($tokenFilePath, json_encode($client->getAccessToken()));
}
return $client;
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$io = new SymfonyStyle($input, $output);
$client = $this->getClient();
$gmail = new \Google_Service_Gmail($client);
$list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 10]);
while ($list->getMessages() != null) {
foreach ($list->getMessages() as $mlist) {
$message_id = $mlist->id;
$io->text($message_id);
}
if ($list->getNextPageToken() != null) {
$pageToken = $list->getNextPageToken();
$list = $gmail->users_messages->listUsersMessages('me', ['pageToken' => $pageToken, 'maxResults' => 1000]);
} else {
break;
}
}
$io->success('Success');
}
}
另外,我认为更好的解决方案是将getClient
函数移至服务,在命令构造函数中获取容器参数,init \\Google_Service_Gmail
和类型提示GmailService:
# /src/Command/UploadFromUnreadEmailsCommand.php
private $gmailService;
public function __construct(GmailService $gmailService)
{
$this->gmailService = $gmailService;
}
