使用httpwebrequest下载经过数字签名的msi文件 [英] download a digitally signed msi file using httpwebrequest

问题描述

大家好，

我在使用httpwebrequest / httpwebresponse class下载MSI文件时遇到了问题。

是的，我可以获得响应流，然后我使用FileStream将文件保存到本地，但是当我执行该文件时，它无法正常运行。

但是当我使用WebClient下载时同样的文件，它工作正常。

目标uri进行测试是办公室365登录助手， 链接是

https://bposast.vo.msecnd.net/MsoIdcrlGa/4209/x64/en /msoidcrl.msi

当我使用httpwebrequest / httpwebresponse时，是否有额外的工作要下载数字签名文件？

谁可以给我一些 非常感谢帮助！

谢谢，

此下载似乎有两个部分： 第一部分是有效载荷......

第二部分是：

第二部分是证书部分，它要小得多。 我相信你必须能够处理这两个部分，但我不确定协议或如何做到这一点。 如果我们考虑证书如何工作，我相信证书
被放入证书商店。 当应用程序运行它告诉操作系统时，我需要一个证书。 操作系统随后前往商店查找所需内容。

Hi all,

I'v encountered a problem while downloading a MSI file using httpwebrequest/httpwebresponse class.

that is, I can get the response stream and then I used FileStream to save the file to local, but when I execute the file, it cannot run properly.

but when I used WebClient to download the same file, it worked fine.

the target uri for testing is the office 365 sign in assistant, the link is

https://bposast.vo.msecnd.net/MsoIdcrlGa/4209/x64/en/msoidcrl.msi

is there any extra work to do to download a digitally signed file when I use httpwebrequest/httpwebresponse ?

any one who can give me some  help is very appreciated!

Thanks,

There seems to be two parts to this download:  The first part is the payload...

The second part is this:

The second part is the certificate portion and it's much smaller.  I believe that you have to be able to handle both parts but am unsure of the protocol or how to do it.  If we think about how certificates work though I believe the certificate is put into the certificate store.  When the application runs it tells the OS, I need a certificate.  The OS then goes to the store to find what is needed.
