google-apps-script - muteHttpExceptions = true 抛出身份验证失败

Question

使用Google Apps Email Settings API使用以下脚本删除委托(delegate)。如果发生错误，例如尝试删除不存在的委托(delegate)，则会返回以下消息:

Exception: Request failed for returned code 400. Truncated server response: <xml version="1.0" encoding="UTF-8"?> <AppsForYourDomainErrors> <error errorCode="1303" invalidInput="XXXX@XXXX.com" reason="E... (use muteHttpExceptions option to examine full response)

但是，当使用 muteHttpExceptions = true 时，身份验证失败:

Exception: Failed to authenticate for service: google

这迫使我使用 try/catch 结构而不是检查 HTTPResponse 对象。我想知道为什么会发生这种情况以及如何解决。

测试函数:

   function test() {
      var consumerKey = 'XXXX';
      var consumerSecret = 'XXXX';
      var domain = 'XXXX.com';
      var userName = 'XXXX'
      var delegateName = 'XXXX@XXXX.com'
      var serviceName = 'google';
      var scope = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/';


      var oAuthConfig = UrlFetchApp.addOAuthService(serviceName);
      oAuthConfig.setRequestTokenUrl('https://www.google.com/accounts/OAuthGetRequestToken?scope=' + scope);
      oAuthConfig.setAuthorizationUrl('https://www.google.com/accounts/OAuthAuthorizeToken');
      oAuthConfig.setAccessTokenUrl('https://www.google.com/accounts/OAuthGetAccessToken');
      oAuthConfig.setConsumerKey(consumerKey);
      oAuthConfig.setConsumerSecret(consumerSecret);

      var fetchParameters = {};
      fetchParameters.oAuthServiceName = serviceName;
      fetchParameters.oAuthUseToken = 'always';
      fetchParameters.method = 'DELETE';
      fetchParameters.muteHttpExceptions = false;

      try {
        var url = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/'+ domain + '/' + userName + '/delegation/' + delegateName;
        var result = UrlFetchApp.fetch(url, fetchParameters);
      } catch (e) {
        Logger.log(e);
      }
    }

此问题已发布到 Google Apps 脚本问题跟踪器，编号为 ticket 3478和 acknowledged as a bug 。票证仍然开放，但 the following workaround has been proposed :

1. Revoking access in your Google Account's Security settings to both www.google.com AND the source of Apps Script (spreadsheet etc).

2. Change the oAuthServiceName parameter to something else.

3. Re-running the script
