我如何使我的PHP应用程序从不要求提供Gmail API验证码？

Question

我希望该应用程序自动运行，但是在进行测试时，如果我们度过了一个周末而又不会在星期一碰到它，那么该应用程序要做的第一件事是：

在浏览器中打开以下链接：https://accounts.google.com/o/oauth2/(...)输入验证码：

我曾经在网上的某个地方看到有必要加粗下面代码中的选项；但无法正常工作。

use GuzzleHttp\Client;
require __DIR__ . '/vendor/autoload.php';
if (php_sapi_name() != 'cli') 
    throw new Exception('This application must be run on the command line.');


// @return Google_Client the authorized client object
function getClient()

    $guzzleClient = new GuzzleHttp\Client([
                'proxy' => '<my_ip_proxy_pfsense>:<port>',
                'verify' => false,
        ]);

$client = new Google_Client();
$client->setApplicationName('RS Gmail Check API PHP');
$client->setScopes(Google_Service_Gmail::GMAIL_READONLY);
$client->setAuthConfig('credentials.json');
**$client->setAccessType('offline');**
// Using "consent" ensures that your application always receives a refresh token.
// If you are not using offline access, you can omit this.
**$client->setApprovalPrompt("consent");
$client->setIncludeGrantedScopes(true);   // incremental auth**
//
$client->setPrompt('select_account consent');
$client->setHttpClient($guzzleClient);

$tokenPath = '/opt/gmail-check/token.json';
    if (file_exists($tokenPath)) 
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
     else 
        $authUrl = $client->createAuthUrl();
        header('Location: ' . filter_var($authUrl, FILTER_SANITIZE_URL));
        if (isset($_GET['code'])) 
            $authCode = $_GET['code'];
            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
            header('Location: ' . filter_var($this->redirectUri, 
            FILTER_SANITIZE_URL));

if(!file_exists(dirname($this->tokenFile))) 
                mkdir(dirname($this->tokenFile), 0700, true);
            

            file_put_contents($this->tokenFile, json_encode($accessToken));
        else
            exit('No code found');
        
        
    $client->setAccessToken($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 
$authUrl = $client->createAuthUrl();
            printf("Open the following link in your browser:\n%s\n", $authUrl);
            print 'Enter verification code: ';
            $authCode = trim(fgets(STDIN));

                throw new Exception(join(', ', $accessToken));
             // */
        
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) 
            mkdir(dirname($tokenPath), 0700, true);

    return $client;


// 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.

                $message_sender = str_replace('"', '', $message_sender);
            
        

            $inboxMessage = [

            // If we didn't find a body, let's look for the parts

                            if($p['mimeType'] === 'text/html' && $p['body']) 
                                $FOUND_BODY = decodeBody($p['body']->data);

Update：这个周末我花了一些时间使用Gmail API对另一个项目进行了测试，但是基于我在服务中使用的相同代码，即使我花了5多个小时没有运行该应用程序，多次要求提供令牌。。最重要的区别在于，在服务中，GuzzleClient配置为与代理一起使用（这将是我们的pfsense防火墙）。我是否由于代理问题而在工作中过期了此令牌问题？
