我在没有所有权的情况下删除文档的所有尝试都失败了。
到目前为止我尝试了什么
在我的最后一次尝试中;我正在尝试遵循此主题中建议的解决方案
Delete a file from different owner with Google Drive API
以服务帐户登录（服务帐户已获得域范围授权https://developers.google.com/drive/web/delegation授权）（成功）
模仿作为文档的所有者。 （成功）
尝试将所有者更改为驱动管理员帐户。 （对此文件的权限不足而失败）
尝试删除文档（对此文件的权限不足而失败）
示例代码“
String serviceAccountEmail = "xxxxxx-bpoaj0ekfgcort8tcqpqh661ceet9pqs@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"key.p12", "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = Scopes,
User = "user" //<<-- I populate this with the user to impersonate
}.FromCertificate(certificate));
// Create the service.
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Drive API Sample",
});
UpdatePermission(service, d.DocId__c , permission_id, "owner"); //<-- updating the permissions of the admin account to owner
FilesResource.DeleteRequest request = service.Files.Delete(d.DocId__c);
String response = request.Execute(); //<-- deleting the doc here, do i need to login again using admin account?
答案 0 :(得分：0)
通过更改UpdatePermission方法以使用TransferOwnership = true来解决问题;包含完整的代码段
