打开PDF结果与MVC 3浏览器选项卡 [英] Open PDF result in browser tab with MVC 3

问题描述

我使用ASP.NET MVC 3，我有一个返回PDF文件这样的控制器动作：

I am using ASP.NET MVC 3. I have a controller action that returns a PDF file like this:

Public Class ReportController
    ...
    Function Generate(id As Integer) As ActionResult
        ...
        Return File(output, "application/pdf", "something.pdf")
        ' "output" is a memory stream
    End Function

在code的作品，但Firefox不会在标签显示的结果，结果被下载或使用Adobe Reader打开。

The code works but Firefox doesn't display the result in a tab, the result is either downloaded or opened with Adobe Reader.

我知道的火狐可以在标签显示PDF 的，因为我可以只是谷歌的一些PDF，点击链接，和PDF将在标签中打开。

I know that Firefox can display PDF in a tab because I can just google some PDF, click the link, and the PDF will open in a tab.

我如何设置的动作使PDF将在标签中打开？

How do I set up the action so the PDF will open in a tab?

推荐答案

我从<一个答案href=\"http://stackoverflow.com/questions/3724278/asp-net-mvc-how-can-i-get-the-browser-to-open-and-display-a-pdf-instead-of-displ/3724471#3724471\">related右侧链接：

Response.AppendHeader("Content-Disposition", "inline")
Return File(output, "application/pdf")

该PDF在选项卡中打开，但文件名提示丢失，即使我做这样的：

The PDF opens in a tab, but the filename hint is lost, even if I do it like this:

Response.AppendHeader("Content-Disposition", "inline; filename=something.pdf")
Return File(output, "application/pdf", "something.pdf")

所以最后我没有刻意去给文件名暗示都没有。

So finally I didn't bother to give filename hint at all.

修改

ASP.NET MVC 3的文件有3个参数：

ASP.NET MVC 3's File with 3 parameters:

Return File(output, "application/pdf", "something.pdf")

将新增内容处置：附件;文件名=something.pdf来响应头，即使已经有一个内容处置的响应头。

will add Content-Disposition: attachment; filename="something.pdf" to the response header, even if there is already a Content-Disposition in the response header.

所以，如果你手动添加内容处置的标题，然后使用文件与3个参数，你最终的两个内容处置头。火狐8会说，如果响应头是这样的反应被破坏。

So if you manually added Content-Disposition to the header, and then use File with 3 parameters, you end up with two Content-Disposition headers. Firefox 8 will say that the response is corrupted if the response header is like this.

所以，最好的办法现在要做的是添加内容处置手动为内联，然后用文件有两个参数：

So best way to do it now is add Content-Disposition manually for 'inline', and then use File with 2 parameters:

Response.AppendHeader("Content-Disposition", "inline; filename=something.pdf")
Return File(output, "application/pdf")
