google-apps-script - 如何启用 OAuth Google 脚本，而无需每次 token 过期时都登录？

Question

此 .gs 代码检查文档是否已授权，如果是，则运行发布请求。我尝试只提供 OAuth 一次，而不是每次 token 过期时提供，任何建议都将受到赞赏!

function Gmail() {

  if (service.hasAccess()) {
  var toolKeyFinal = service.getAccessToken();

//*******request would run with token here********

   }
  else{
      var authorizationUrl = service.getAuthorizationUrl();
      var string = toolName+" Authorization (then try formula again 👍),"+authorizationUrl;
      var auth = [{}];
      return string.split(",")
  }
}

  
function getServiceGmail() {
  return OAuth2.createService('Gmail')
      .setAuthorizationBaseUrl('https://accounts.google.com/o/oauth2/auth')
      .setTokenUrl('https://accounts.google.com/o/oauth2/token')
      .setClientId('CLIENT-ID')
      .setClientSecret('CLIENT-SECRET')
      .setCallbackFunction('authCallback')
      .setPropertyStore(PropertiesService.getDocumentProperties())
      .setScope('https://mail.google.com/');
};

/**
 * Handles the OAuth callback.
 */
function authCallback(request) {
  var service = getServiceGmail();
  var authorized = service.handleCallback(request);
  if (authorized) {
    return HtmlService.createHtmlOutput(
    "<script>window.top.location.href='https://REDIRECT.com';</script>"
  );
    //return HtmlService.createHtmlOutput('PowerSheet authorization successful for your Google Sheet! You can close this tab.');
  } else {
    return HtmlService.createHtmlOutput('You did not provide authorization. Please close this tab and try again.');
  }
}

根据documentation :

A Google Cloud Platform project with an OAuth consent screen configured for an external user type and a publishing status of "Testing" is issued a refresh token expiring in 7 days.

因此，对于外部(又名面向用户的)应用程序，您必须升级 publishing status通过 Google 的审核和验证流程，将其更改为“正在生产中”。

此外，由于您使用的是受限范围 (https://mail.google.com/)，您还必须接受安全评估，该评估可能会让您花费 8 美元起k 至 7.5 万美元(参见 Security Assessment)
