谷歌应用程序脚本，OAuth要求匿名登录

我正试图从我拥有的文档中提取修订历史记录。当我调试它时，我收到一个401错误，需要登录。但是，我尝试使用匿名ConsumerKey/ConsumerCret传递登录名，当我调试它时，urlFetch返回为未定义。以下是我目前掌握的代码：

//Get revison history
//fileId is the ID of the resource from Google Docs
function getRevisionHistory(fileId){

//Scope
var scope = 'https://www.googleapis.com/auth/drive';

//Get Google oAuth Arguments
var fetchArgs = googleOAuth_('docs', scope);

//Set the fetch method
fetchArgs.method = 'LIST';

//Feed URL
var url = 'https://www.googleapis.com/drive/v2/files/' + fileId + '/revisionsv=3&alt=json';
var urlFetch = UrlFetchApp.fetch(url);

//Get the json of revision history entry
var jsonFeed = Utilities.jsonParse(urlFetch.getContentText()).feed.entry;
//return the revison history feed
return jsonFeed
}

//Google oAuth
//Used by getRevisionHistory
function googleOAuth_(name, scope) {
  var oAuthConfig = UrlFetchApp.addOAuthService(name);
  oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
  oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
  oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
  oAuthConfig.setConsumerKey("anonymous");
  oAuthConfig.setConsumerSecret("anonymous");
return {oAuthServiceName:name, oAuthUseToken:"always"};
}

function trackChanges(jsonFeed){
  var doc = DocumentApp.getActiveDocument();
  var docName = doc.getName();
  var docId = doc.getId();

  getRevisionHistory(docId)
  var jsonString = Utilities.jsonStringify(jsonFeed);
  var changes = DocumentApp.create("Track Changes for " + docName);
  var text = changes.getBody().editAsText();
  text.appendText(jsonString);
   }

任何帮助都将不胜感激。

尝试向驱动器API的UrlFetch调用添加API键（

&Key=mykey

）。您可以在启用驱动器API并获取API密钥
