在 Google Apps 脚本中将文件的所有权转让给其他用户

Question

我创建了一个小的上传 UI，我将其包含在 Google 协作平台页面中。它让用户上传一个文档。由于脚本已发布，它在我的帐户下运行，并且上传的文件上传到我的谷歌驱动器。我可以从应用程序脚本中将上传文件的人添加为编辑器，但我想做的是让他们成为文件的所有者。 （从应用程序脚本中，您可以对文件执行 .getOwner() ......但不是 .setOwner() .....有人知道解决方法吗？

Answer 1

很遗憾，Apps 脚本不支持更改文件的所有者。 Issue 74 是添加此功能的功能请求，如果您在问题上加注星标，您将表示您对该功能的支持并收到更新通知。

现在有一个方便的方法叫做 setOwner，可以在这里找到：https://developers.google.com/apps-script/reference/drive/file#setOwner(User)

还有可能传递新所有者的电子邮件地址而不是 User 对象，这在某些情况下更加方便： https://developers.google.com/apps-script/reference/drive/file#setOwner(String)

2016 年 9 月 12 日更新：

此代码使用已授予Google Apps Domain-Wide Delegation of Authority 的服务帐户。这使您可以更改域中任何用户拥有的任何文件的所有者。此代码使用 Eric Koleda 的 Google apps-script-oauth2 库。

var PRIVATE_KEY  = PropertiesService.getScriptProperties().getProperty('PRIVATE_KEY'); 
var CLIENT_EMAIL = PropertiesService.getScriptProperties().getProperty('CLIENT_EMAIL');

/**
* Transfers ownership of a file or folder to another account on the domain.
*
* @param  {String} fileId The id of the file or folder
* @param  {String} ownerEmail  The email address of the new owner.
*/
function transferOwnership(fileId, ownerEmail) {
  var file = DriveApp.getFileById(fileId);
  var currentOwnerEmail = file.getOwner().getEmail(); //the user that we need to impersonate

  var service = getService(currentOwnerEmail);
  if (service.hasAccess()) {
    var url = 'https://www.googleapis.com/drive/v2/files/' + fileId + '/permissions'; 
    var payload = {value: ownerEmail,
                   type: 'user',
                   role: 'owner'};
    var options = {method: "post",
                   contentType: "application/json",
                   headers : {
                     Authorization: 'Bearer ' + service.getAccessToken()
                   },
                   payload: JSON.stringify(payload)//,
                   ,muteHttpExceptions: true
                  };        
    //debugger;
    //throw 'test my errors';

    var response = UrlFetchApp.fetch(url, options);
    if (response.getResponseCode() === 200 || 
        (response.getResponseCode() === 400 && response.getContentText().indexOf('were successfully shared'))
    ) {
      return response.getContentText();
    }
    if (response.getResponseCode() === 401 && response.getContentText().indexOf('Invalid Credentials')) {
      throw 'Unable to transfer ownership from owner ' + currentOwnerEmail + ' ... ' +
        'Please make sure the file\'s owner has a Google Apps license (and not a Google Apps Vault - Former Employee license) and try again.';
    }
    throw response.getContentText(); 
  } else {
    throw service.getLastError();
  }
}

/**
 * Reset the authorization state, so that it can be re-tested.
 */
function reset() {
  var service = getService();
  service.reset();
}

/**
 * Configures the service.
 */
function getService(userEmail) {
  return OAuth2.createService('GoogleDrive:' + userEmail)
      // Set the endpoint URL.
      .setTokenUrl('https://accounts.google.com/o/oauth2/token')

      // Set the private key and issuer.
      .setPrivateKey(PRIVATE_KEY)
      .setIssuer(CLIENT_EMAIL)

      // Set the name of the user to impersonate. This will only work for
      // Google Apps for Work/EDU accounts whose admin has setup domain-wide
      // delegation:
      // https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority
      .setSubject(userEmail)

      // Set the property store where authorized tokens should be persisted.
      .setPropertyStore(PropertiesService.getScriptProperties())

      // Set the scope. This must match one of the scopes configured during the
      // setup of domain-wide delegation.
      .setScope('https://www.googleapis.com/auth/drive');
}

旧答案（现在已过时，因为文档列表 API 已弃用）：

您可以在 Google Apps 脚本中通过使用原始 atom xml 协议访问文档列表 API 来实现此目的。您需要成为域的超级管理员。这是一个适合我的示例：

/**
* Change Owner of a file or folder 
* Run this as admin and authorise first in the script editor.
*/ 
function changeOwner(newOwnerEmail, fileOrFolderId){
  var file = DocsList.getFileById(fileOrFolderId);
  var oldOwnerEmail = file.getOwner().getEmail();
  if (oldOwnerEmail === newOwnerEmail) {
    return;
  }
  file.removeEditor(newOwnerEmail);
  var base = 'https://docs.google.com/feeds/';
  var fetchArgs = googleOAuth_('docs', base);
  fetchArgs.method = 'POST';
  var rawXml = "<entry xmlns='http://www.w3.org/2005/Atom' xmlns:gAcl='http://schemas.google.com/acl/2007'>"
      +"<category scheme='http://schemas.google.com/g/2005#kind' "
      +"term='http://schemas.google.com/acl/2007#accessRule'/>"
      +"<gAcl:role value='owner'/>"
      +"<gAcl:scope type='user' value='"+newOwnerEmail+"'/>"
      +"</entry>";
  fetchArgs.payload = rawXml;
  fetchArgs.contentType = 'application/atom+xml';
  var url = base + encodeURIComponent(oldOwnerEmail) + '/private/full/'+fileOrFolderId+'/acl?v=3&alt=json';
  var content = UrlFetchApp.fetch(url, fetchArgs).getContentText(); 
}

//Google oAuth
function googleOAuth_(name,scope) {
  var oAuthConfig = UrlFetchApp.addOAuthService(name);
  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("anonymous");
  oAuthConfig.setConsumerSecret("anonymous");
  return {oAuthServiceName:name, oAuthUseToken:"always"};
}

Answer 3

试试这个！ （至少它对我有用）

var newFolder = DriveApp.createFolder(folderName).addEditor(ownerEmail).setOwner(ownerEmail).addEditor(group.getEmail()).removeEditor(Session.getActiveUser().getEmail());     

上面创建了一个文件夹并添加了一个新编辑器，将新编辑器设置为所有者，将另一个组添加到编辑器中，最后从编辑器中删除刚刚创建文件夹的用户。

我想出了一个解决方法——不确定它是否正是你们所寻找的。只需授予您要切换所有权的帐户的访问权限即可。访问文档/表单/等。从该帐户中提取，然后制作该文件的副本。您现在是所有者。您必须重新邀请其他人。
