在.aspx页面中有一个.pdf文件,像这样:<嵌入SRC =HTTP://.../ShowPdf.aspx ID = 1类型=应用程序/ PDF>
。 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?
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。
I hope that I had helped you.
