当我强迫从网页下载文件时，它通过SPACE / C＃拆忒文件名？ [英] When I force downloading a file from a page, it split te file name by SPACE /C#?

问题描述

下面是我的code为强制下载：

Here is my code for the Force Download:

        // URL = Download.aspx?Url=How to use the Application.txt    

        string q = Request.QueryString["Url"].ToString();

        Response.Clear();
        Response.AddHeader("Content-disposition", "Attachment; Filename=" + file);
        Response.ContentType = "Text/Plain";
        Response.WriteFile(Server.MapPath("Directory/" + q));
        Response.End();

对话框，在Firefox中apears说：你要打开的文件：
和文件名显示只是个屁如何（这个名字应该是：如何使用Application.txt）。萨玛我提到，如果我尝试赖特文件名，我的自我：

The Dialog Box that apears in Firefox says: You are going to open the file: And the filename is displayed just ass How (the name should be: How to use the Application.txt ). The sama I mentioned if I try to wright the filename for my self:

Response.AddHeader("Content-disposition", "Attachment; Filename=How to use the Application.txt");

同样apears。请帮助！

The same apears. Please Help!

推荐答案

哑剧文件名应该用双引号。

Mime files names should be double quoted.

Response.AddHeader("Content-disposition", 
                   "Attachment; Filename=\"" + file + "\"");

这可以 RFC中找到2616（HTTP 1.1）

内容处置：附件;文件名=fname.ext

Content-Disposition: attachment; filename="fname.ext"

修订 RFC 6266 允许不带引号文件名太多，如果他们不含有禁止charecters像的空间。

Revised in RFC 6266 to allow file names without quotes too if they didn't contain disallowed charecters like spaces.

内容处置：附件;文件名= example.html的

Content-Disposition: Attachment; filename=example.html
