现有的Azure Blob的内容处置是否可能? [英] Is it possible to the content disposition of an existing Azure blob?

问题描述

基于stimms在这里回答: Azure Storage API ContentDisposition

Based on stimms answer here: Azure Storage API ContentDisposition

以及在此处找到的信息: 公共下载Azure blob时的友好文件名

and the information found here: Friendly filename when public download Azure blob

上传新文件时，我已经可以设置内容的处理方式.但是我也希望能够设置现有文件的内容处置.

I have been able to set the content disposition when uploading new files. But I also would like to be to able to set the content disposition of existing files.

blob.Properties.ContentDisposition = string.Format("attachment;filename=\"{0}\"", friendlyName);

在上传文件之前进行设置时可以很好地工作，但是如果在现有的Blob上尝试它没有任何作用.

works fine when set before uploading a file, but has no effect if I try it on an existing blob.

更改存在的Blob的内容处置只是根本不可能还是我做错了什么?

Is is just plain impossible to change the content disposition of an existing blob or am I doing something wrong?

推荐答案

是.设置ContentDisposition后，只需在Blob上调用SetProperties()方法即可.因此您的代码应为:

Yes. You just have to call SetProperties() method on the blob after you set ContentDisposition. So your code should be:

            blob.FetchAttributes();//Fetch properties first so that you don't overwrite existing properties when you call SetProperties
            blob.Properties.ContentDisposition = string.Format("attachment;filename=\"{0}\"", friendlyName);
            blob.SetProperties();
