blob.Properties.ContentType 写入 Blob 容器时始终是应用程序/八位字节流

Question

我只是将 json 文件写入 Blob（请参阅下面的代码）。我需要它是 content = application/json 但 blob json 文件每次都会读取“application/octet-stream”。我已将 blob.properties ContentType 设置为 =“application/json”，但是当我查看存储资源管理器时，它每次都会显示“application/octet-stream”。

static public void WriteBlob(string filename, string data)
        {
            string storageConnectionString = "DefaultEndpointsProtocol=https;AccountName=scadametrics;AccountKey=xxxxxxxxxxnfrsFRd/49Dmhn0HwKbxmpiA==;EndpointSuffix=core.windows.net";
            var storageAccount = CloudStorageAccount.Parse(storageConnectionString);
            var client = storageAccount.CreateCloudBlobClient();
            var container = client.GetContainerReference("azfunc-out");
//            string fileName = companyId.ToString() + "\\" + Guid.NewGuid();
            var blob = container.GetBlockBlobReference(filename);
            blob.Properties.ContentType = "application/json";

            using (CloudBlobStream x = blob.OpenWriteAsync().Result)
            {
                byte[] bytes = Encoding.ASCII.GetBytes(data);
                x.Write(bytes, 0, bytes.Length);
                x.Flush();
                x.Close();
            }
        }

您应该调用

blob.SetPropertiesAsync

来真正将内容类型保存到服务器。
