如何在Google Apps脚本中包含AWS Cognito身份验证？

如何解决如何在Google Apps脚本中包含AWS Cognito身份验证？

我们正在尝试通过aws-cognito-identity通过身份验证通过Google Sheet的应用脚本访问数据库。我什至没有上手的麻烦，因为我不确定如何导入模块，因为这不是一个node.js环境。是否有人有这样做的经验并且不愿意分享？ 谢谢

解决方法

这就是我让它工作的方式：

var authEndpoint = "https://[put your auth domain here].amazoncognito.com/oauth2/token";
var authClientId = "[put your Cognito client ID here]";
var authSecret = "[put your Cognito auth secret string here]";
var authExpirationTime = undefined;
var authLatestToken = undefined;

function getAuthToken() {
  // If last known token is still valid,use it.
  if (authLatestToken && authExpirationTime && authExpirationTime < new Date().getTime()) {
    return authLatestToken;
  }

  // Otherwise,request new token from AWS Cognito
  var params = {
    method: "POST",followRedirects: true,headers: {
      "Content-Type": "application/x-www-form-urlencoded","Authorization": "Basic " + Utilities.base64Encode(authClientId + ":" + authSecret)
    },payload: "grant_type=client_credentials"
  };
  var response = UrlFetchApp.fetch(authEndpoint,params);

  // Verify response
  if (response.getResponseCode() !== 200) {
    throw new Error("Authentication failed: HTTP Response not OK.");
  }
  var data = JSON.parse(response.getContentText());
  if (!data.access_token) {
    throw new Error("Authentication failed: No token returned.");
  }

  // Set internal vars and return token
  authLatestToken = data.access_token;
  if (data.expires_in > 0) {
    authExpirationTime = new Date().getTime() + data.expires_in * 1000;
  }
  return authLatestToken;
}

然后你可以在任何需要认证的请求中添加带有这个承载的授权头，例如：

    headers: {
      "Content-Type": "application/json","Authorization": "Bearer " + getAuthToken()
    },
