Question

我想从文件中删除权限。

在Drive API v2中，

PermissionId permissionId = service.permissions().getIdForEmail(account).execute();
service.permissions().delete(fileId, permissionId.getId()).execute();

但是根据文档，权限（）。getIdForEmail（字符串电子邮件）被删除，而备用则没有。

我无法找到如何从驱动API v3中的特定电子邮件地址获取permissionId。

你有什么想法吗？

Answer 1

两年后，但您的问题是我在搜索解决方案时找到的第一个结果。我找到了一个解决方法，我希望这会帮助其他人解决同样的问题。这就是我为获取权限ID所做的工作：

this.getPermissionId = function(emailAddress) {
    return new Promise((resolve, reject) => {

      const input = {
        q:  '"' + emailAddress + '" in writers or "' + emailAddress + '" in readers',
        fields: 'files(permissions)',
        pageSize: 1
      };

      const request = gapi.client.drive.files.list(input);

      request.execute(result => {
        if(result.error) {
          reject(result.error);
        } else if(result.files && result.files[0] && result.files[0].permissions && result.files[0].permissions[0]) {
          const permissions = result.files[0].permissions;
          let permissionId;
          permissions.forEach(permission => {
            if(permission.emailAddress == emailAddress) {
              permissionId = permission.id;
            }
          });

          if(permissionId) {
            resolve(permissionId);
          }

          else {
            reject('permissionIdUndefined');
          }
        }
      });


    })
  };

我找到了一个简单的解决方案：

        PermissionList permissions = service.permissions().list(sharedFolderId).setFields("nextPageToken, permissions(id,emailAddress)").execute();
        for (Permission p : permissions.getPermissions()) {
            if (p.getEmailAddress().equals(adresseEmail)) {
                service.permissions().delete(sharedFolderId, p.getId()).execute();
            }
        }

解决了我的需求的.NET版本

    public static string GetPermissionIdForEmail(DriveService service, string emailAddress)
    {
        string pageToken = null;

        do
        {
            var request = service.Files.List();
            request.Q = $"'{emailAddress}' in writers or '{emailAddress}' in readers or '{emailAddress}' in owners";
            request.Spaces = "drive";
            request.Fields = "nextPageToken, files(id, name, permissions)";
            request.PageToken = pageToken;

            var result = request.Execute();

            foreach (var file in result.Files.Where(f => f.Permissions != null))
            {
                var permission = file.Permissions.SingleOrDefault(p => string.Equals(p.EmailAddress, emailAddress, StringComparison.InvariantCultureIgnoreCase));

                if (permission != null)
                    return permission.Id;
            }

            pageToken = result.NextPageToken;

        } while (pageToken != null);

        return null;
    }

我已经使用C＃在.NET中完成了这段代码。

我希望您已经使用用户的访问令牌创建了驱动器服务。

之后，此代码可以帮助您获取许可ID：

 var permissionFile = driveService.About.Get();
 permissionFile.Fields = "*";
 var perm = permissionFile.Execute();
 permissionId = perm.User.PermissionId;

permissionId将为您提供所需的ID。

我将UrlFetchApp与Google Apps脚本一起使用，以替换Drive API v2和Advanced Drive Service（基于v2）。

使用公司域服务帐户，第getService(userEmail)节使用库https://github.com/googleworkspace/apps-script-oauth2代表userEmail发送请求。

/**
 * Get user permission Id.
 *
 * @param {String} userEmail - Email address for About query.
 * https://developers.google.com/drive/api/v3/reference/about
 */
function TEST_getIdForEmailV3() { getIdForEmailV3('YourEmail@CompanyDomain.com') }
function getIdForEmailV3(userEmail) {
  var service = getService(userEmail);
  if (service.hasAccess()) {

    var url = 'https://www.googleapis.com/drive/v3/about' + '?fields=user/permissionId';
    var options = {
      'method': 'get',
      'contentType': 'application/json',
      'headers': { Authorization: 'Bearer ' + service.getAccessToken() }
    };
    
    var response = UrlFetchApp.fetch(url, options);
    var resultParsed = JSON.parse(response.getContentText());
    return resultParsed.user.permissionId;
    
  } else {
    return 0;
  };
}

如何在Drive API v3中获取permissionId？
