替换Google Cloud存储中的对象，然后替换Cloud CDN花费时间刷新缓存

问题描述

我已启用Google Cloud Storage版本来替换相同名称的图像，例如3-4分钟后刷新或有时不刷新。我正在使用.net core来管理替换，但没有得到解决方案。问题是用户可以随时上传同名图片。这是我的代码。

public virtual void UploadGoogle(string localPath,string location,string contentType)
    {
        try
        {


            bool cdnStatus = Convert.ToBoolean(_configuration.GetSection("AppSetting")["GoogleCdnStatus"]);
            if (cdnStatus)
            {
                var gcpPath = _configuration.GetSection("GoogleCloudStorage")["fileName"];
                var gcpCredential = Path.Combine(_hostingEnvironment.ContentRootPath,gcpPath);
                var gcpstorageCredential = GoogleCredential.FromFile(gcpCredential);
                // Instantiates a client.
                using (StorageClient storageClient = StorageClient.Create(gcpstorageCredential))
                {
                    // The name for the new bucket.
                    string bucketName = _configuration.GetSection("AppSetting")["Googlebucket"];
                    using (var f = System.IO.File.OpenRead(localPath))
                    {
                        //objectName = objectName ?? Path.GetFileName(localPath);
                        //UploadobjectOptions uploadobjectOptions = new UploadobjectOptions();
                        //uploadobjectOptions.
                        //if (localPath.Contains("Profile"))
                        //{

                        //    //storageClient.DeleteObject(bucketName,location);
                        //    try
                        //    {
                        //        Bucket bucket = new Bucket();
                        //        bucket = storageClient.GetBucket(bucketName);
                        //        Bucket.VersioningData versioningData = new Bucket.VersioningData();
                        //        versioningData.Enabled = true;
                        //        bucket.Versioning = versioningData;
                        //        storageClient.UpdateBucket(bucket);
                        //    }
                        //    catch (Exception ex)
                        //    {


                        //    }

                        //    storageClient.Uploadobject(bucketName,location,contentType,f);

                        //}
                        //else
                        //{
                        //    storageClient.Uploadobject(bucketName,f);
                        //}

                        Bucket bucket = new Bucket();
                        bucket = storageClient.GetBucket(bucketName);
                        Bucket.VersioningData versioningData = new Bucket.VersioningData();
                        versioningData.Enabled = false;
                        bucket.Versioning = versioningData;
                        storageClient.UpdateBucket(bucket);
                        storageClient.Uploadobject(bucketName,f);

                    }
                    //try
                    //{
                    //    // Creates the new bucket.
                    //    storageClient.CreateBucket(projectId,bucketName);
                    //    Console.WriteLine($"Bucket {bucketName} created.");
                    //}
                    //catch (Google.GoogleApiException e)
                    //when (e.Error.Code == 409)
                    //{
                    //    // The bucket already exists.  That's fine.
                    //    Console.WriteLine(e.Error.Message);
                    //}
                }
            }
        }
        catch (Exception ex)
        {

        }
    }

我尝试删除对象并再次上传，但是发生了同样的事情。我与Google支持人员进行了交谈，但他们没有给出想法，实际上为什么会这样，因为他们只是说他们无助于编程。如果您在代码中看到我已经尝试过启用或禁用两种情况。
