Chrome浏览器无法从asp.net页面中显示PDF [英] Chrome not displaying PDF from asp.net page

问题描述

在.aspx页面中有一个.pdf文件，像这样：＆LT;嵌入SRC =HTTP：//.../ShowPdf.aspx ID = 1类型=应用程序/ PDF＆GT; 。 Chrome浏览器只显示加载的形象，并挂而不显示PDF（铬PDF浏览器和Adobe插件两个不工作）。其他浏览器打开PDF文件。任何想法？

An .aspx page has a .pdf file in it, like this: <embed src="http://.../ShowPdf.aspx?id=1" type="application/pdf">. Chrome just shows a "Loading" image and hangs without displaying the pdf (chrome pdf viewer and adobe plugin both don't work). Other browsers open the pdf. Any ideas?

推荐答案

我有这个问题也和我多次调研后，终于解决了这个问题。

I had this problem too and I finally solved it after several researches.

我发现的是， HTTP 响应头应具有以下实体头：

What I found is that the HTTP response header should have the following entity-header:

内容长度：文件大小

如果没有指定这个头，Web服务器就会把默认的：

Without specify this header, the web server will put the default:

内容长度：分块

我不知道为什么谷歌浏览器有这个问题，因为正如你所说，在其他浏览器如IE或Firefox，他们提供/打开正确的PDF文件。

I don't know why Google Chrome has this issue, because as you said, in other browsers like IE or Firefox, they render/open correctly the PDF file.

以下是我的code，我来解决这个问题。它的工作在我的情况，现在谷歌浏览器显示我的Web应用程序的PDF文件！

Following is my code that I used to solve this problem. It worked in my case and now Google Chrome is displaying the PDF file of my web application!

    System.IO.FileInfo fileInfo;
    fileInfo = My.Computer.FileSystem.GetFileInfo(fullPathToFile);
    Response.AddHeader("Content-Length", fileInfo.Length.ToString());

我希望我帮助你。
