Word打开时，已下载的文档已消失 [英] Downloaded document has disappeared by the time Word has opened

问题描述

我们已经实现了允许用户使用以下代码从IIS服务器下载文档（任何

文档类型）的功能：


Response.Clear（）

Response.ContentType =" application / x-msdownload"

Response.AddHeader（" Content-Disposition"，" attachment; filename ="&

System.IO.Path.GetFileName（FilePath））

Response.AddHeader（" Content-Length"，File.Length.ToString（） ）

Response.WriteFile（FilePath）

Response.End（）


当回复此响应时，IE会提示用户是否要打开，保存或取消下载
。如果他们将

文档保存到本地硬盘驱动器然后打开它，它的工作正常。但是，如果他们选择

打开，文件下载（快速），但是当Word打开时，

临时互联网文件中的副本已经消失或从未保存在第一个

的地方。 Word显示有关无法找到文件的错误。


我怀疑它与缓存有关但我可以找到很多帖子

关于停止缓存，我在ASP.NET中找不到任何关于

迫使Word文档缓存的好例子。


任何想法？


谢谢，Rob。

We''ve implemented functionality to allow a user to download a document (any
document type) from the IIS server using the following code:

Response.Clear()
Response.ContentType = "application/x-msdownload"
Response.AddHeader("Content-Disposition", "attachment; filename=" &
System.IO.Path.GetFileName(FilePath))
Response.AddHeader("Content-Length", File.Length.ToString())
Response.WriteFile(FilePath)
Response.End()

When this response is sent back, IE prompts the user whether they want to
open, save or cancel the download. It works perfectly if they save the
document to their local hard drive and then open it. However, if they select
Open, the file downloads (quickly) but by the time Word opens, the copy in
temporary internet files has either disappeared or never saved in the first
place. Word displays an error about "The file could not be found".

I suspect it''s something to do with caching but whilst I can find many posts
about stopping caching, I can''t find any good examples in ASP.NET about
forcing the Word document to cache.

Any ideas?

Thanks, Rob.

推荐答案

似乎好像内容类型明确表示它是用于下载。尝试

使用application / doc;对于Word文件。这将告诉浏览器打开

吧。然后用户可以选择在本地保存它。


或者，尝试设置content-expiration。 IIS中目录的设置

在一分钟后到期（相对于立即）。 Word，PDF和其他人在浏览器中打开时会立即过期

问题。

It seems as if the content-type specifically says it is for downloading. Try
using "application/doc" for Word files. This will tell the browser to open
it. The user then can optionally save it locally.

Or, try setting the "content-expiration" setting for the directory in IIS to
expire in one minute(versus immediately). Word, PDF, and others have had a
problem being opened in the browser with expire-immediately.

你好Rob，


我想你可以试试Brad的建议调整响应对象的内容类型

属性。根据您提供的代码，除了内容类型值之外，没有其他特殊内容可以使用
。一般来说，

我们总是可以使用application / octet-stream。对于所有二进制数据

溪流。

如果还有其他任何发现，请随时在此发布。


谢谢，

Hi Rob,

I think you can try Brad''s suggestion on adjusting the Content Type
property of your response object. Based on the code you provided, there
seems no other particular things except the content-type value. Generally,
we can always use the "application/octet-stream" for all binary data
streams.
If there''re any other findings, please feel free to post here.

Thanks,

Steven Cheng

这个问题是我们不必为每个

不同的内容类型编码/提供程序并生成不同的内容类型？

> using "application/doc" for Word files. This will tell the browser to open

The problem with this is that don''t we then have to code/cater for every
different content type in the program and generate different content-types?

或者，尝试设置内容过期。 IIS
中的目录设置在一分钟后到期（相对于立即）。 Word，PDF和其他人在浏览器中打开时会立即过期。

Or, try setting the "content-expiration" setting for the directory in IIS to expire in one minute(versus immediately). Word, PDF, and others have had a
problem being opened in the browser with expire-immediately.

这可能更有用。您将哪个目录设置为源文件夹的目的地为

？


谢谢，Rob。

Ahh this might be more useful. Which directory do you set the expiry on as
the source folder varies?

Thanks, Rob.
