C# Google Drive API/SDK所有权转移

我正在尝试将特定文件的所有权转移给其他用户。

总代码

foreach (Permission permission in RetrievePermissions(service(), file.Id))
        {
            if (permission.Role == EnumClass.PERMISSIONROLE.OWNER.ToText())
            {
                //Downgrade Owner Writer
                UpdatePermission(service(), file.Id, permission.Id, EnumClass.PERMISSIONROLE.WRITER);
                //Create New Writer
                InsertPermission(service(), file.Id, ownerMail, EnumClass.PERMISSIONROLE.WRITER);

                foreach (Permission thisPermission in RetrievePermissions(service(), file.Id))
                {   //Update Writer to Owner
                    if (thisPermission.Name == "Person X")
                    {
                        //Set Person X as new Owner
                        UpdatePermission(service(), file.Id, thisPermission.Id, EnumClass.PERMISSIONROLE.OWNER);
                    }
                }
            }
        }

更新权限方法

public static Permission UpdatePermission(DriveService service, String fileId, String permissionId, EnumClass.PERMISSIONROLE ROLE)
    {
        try
        {
            // First retrieve the permission from the API.
            Permission permission = service.Permissions.Get(fileId, permissionId).Execute();
            permission.Role = ROLE.ToText();

            //if new Role is Owner, Downgrad current Owner
            if (ROLE == EnumClass.PERMISSIONROLE.OWNER)
            {
                var myPermission = service.Permissions.Update(permission, fileId, permissionId);
                myPermission.TransferOwnership = true;

                foreach (Permission per in RetrievePermissions(service, fileId))
                {
                    if (per.Role == EnumClass.PERMISSIONROLE.OWNER.ToText())
                    {
                        per.Role = EnumClass.PERMISSIONROLE.WRITER.ToText();
                    }
                }
            }
            return service.Permissions.Update(permission, fileId, permissionId).Execute();
        }

        catch (Exception e)
        {
            Console.WriteLine("An error occurred: " + e.Message);
        }
        return null;

 public static Permission InsertPermission(DriveService service, String fileId, String userMail, EnumClass.PERMISSIONROLE Role)
    {
        Permission newPermission = new Permission();
        newPermission.Name = userMail;
        newPermission.Value = userMail;
        newPermission.Type = EnumClass.PERMISSIONTYPE.USER.ToText();
        newPermission.Role = Role.ToText();

        try
        {
            return service.Permissions.Insert(newPermission, fileId).Execute();
        }
        catch (Exception InsertError)
        {
            Console.WriteLine("Error inserting permission for " + userMail + Environment.NewLine + "Error on Insert: " + InsertError.Message);
        }
        return null;
    }

插入权限方法

public static Permission UpdatePermission(DriveService service, String fileId, String permissionId, EnumClass.PERMISSIONROLE ROLE)
    {
        try
        {
            // First retrieve the permission from the API.
            Permission permission = service.Permissions.Get(fileId, permissionId).Execute();
            permission.Role = ROLE.ToText();

            //if new Role is Owner, Downgrad current Owner
            if (ROLE == EnumClass.PERMISSIONROLE.OWNER)
            {
                var myPermission = service.Permissions.Update(permission, fileId, permissionId);
                myPermission.TransferOwnership = true;

                foreach (Permission per in RetrievePermissions(service, fileId))
                {
                    if (per.Role == EnumClass.PERMISSIONROLE.OWNER.ToText())
                    {
                        per.Role = EnumClass.PERMISSIONROLE.WRITER.ToText();
                    }
                }
            }
            return service.Permissions.Update(permission, fileId, permissionId).Execute();
        }

        catch (Exception e)
        {
            Console.WriteLine("An error occurred: " + e.Message);
        }
        return null;

 public static Permission InsertPermission(DriveService service, String fileId, String userMail, EnumClass.PERMISSIONROLE Role)
    {
        Permission newPermission = new Permission();
        newPermission.Name = userMail;
        newPermission.Value = userMail;
        newPermission.Type = EnumClass.PERMISSIONTYPE.USER.ToText();
        newPermission.Role = Role.ToText();

        try
        {
            return service.Permissions.Insert(newPermission, fileId).Execute();
        }
        catch (Exception InsertError)
        {
            Console.WriteLine("Error inserting permission for " + userMail + Environment.NewLine + "Error on Insert: " + InsertError.Message);
        }
        return null;
    }

错误

Google.API.Requests.RequestError对此权限不足 文件[403]错误[消息[此文件的权限不足] 位置[-]原因[禁止]域[全局]]

我正在使用ServiceAccount。

感谢大家的帮助

您是否尝试使用模拟

var initializer = new ServiceAccountCredential.Initializer(ServiceAccountEmail)
{
    Scopes = new[] { DriveService.Scope.Drive },
    User = "user@yourdomain.com"
};

转让所有权的最佳方式是

启用对服务帐户的域范围委派

初始化驱动器服务时模拟用户，如下所示：

*

使用（var credentialJSON=newfilestream（_settings.CertificatePath，FileMode.Open，FileAccess.Read））
{
var认证参数=
NewtonsoftJsonSerializer.Instance.Deserialize（credentialJSON）；
凭证=新的ServiceAccountCredential(
新ServiceAccountCredential.Initializer（credentialParameters.ClientEmail）
{
范围=范围，
User=ownerEmailAddress，//输入实际的用户电子邮件地址
}.来自PrivateKey（credentialParameters.PrivateKey））；
}

服务帐户无权访问相关文件。是，但如何解决？请尝试向服务帐户授予该文件的电子邮件地址权限。（不，我没有尝试）serviceAccount是该文件的所有者。您使用该服务帐户创建了该文件？
