如何改变这一个servlet流PDF文件到一个浏览器页面的标题？ [英] How to change the title of a browser page which a servlet streamed a PDF to?

问题描述

我的基于Java的web应用程序有基于请求参数，它流PDF内容返回给浏览器的servlet。

My Java based webapp has a servlet which streams PDF content back to the browser based on request parameter.

例如。用户点击一个标签，对myApp / FetchPDFServlet？ID = 123的一个href。 Servlet映射拿起请求，PDF格式的数据流，以响应为MIME类型的应用程序/ PDF格式，关闭刷新缓冲区。

e.g. user clicks on an A tag with an href of "myApp/FetchPDFServlet?id=123". Servlet mapping picks up request, streams PDF data to response as mime-type application/pdf, closes flushes buffers.

不过，对于显示PDF页面的浏览器的标题栏显示为FetchPDFServlet？ID = 123

However the browser title bar for the page displaying the PDF reads "FetchPDFServlet?id=123"

如何更改标题，浏览器将显示该显示PDF页面？
所以浏览器的标题是这是惊人的PDF而不是FetchPDFServlet？ID = 123。

How can I change the title the browser displays for the page that displays the PDF? So the browser title is "Here is the amazing PDF" not "FetchPDFServlet?id=123".

是否有可能呢？如何最有效地做到这一点？

Is it possible at all? How best to do this?

推荐答案

这头添加到您的HttpServletResponse：

Add this header to your HttpServletResponse:

response.setHeader("Content-Disposition","inline; filename=Here is the Amazing PDF");

我认为浏览器将它捡起来，并把它作为窗口的标题。

I believe the browser will pick it up and use it as the title of the window.
