在浏览器的新标签页中打开PDF [英] Open PDF in a new tab in browser

问题描述

以前从未做过此操作，因此不确定其中涉及什么.我进行了搜索，发现了许多答案，但它们比我需要的要复杂得多.例如，他们需要放大，生成，创建准确的缩略图，在网页中嵌入实际的PDF等.但是我的问题要简单得多: 如果我要在网页上显示其信息的家伙要显示一些PDF，而我只想在页面上放一个通用的PDF图标，人们就可以单击它，而实际的PDF会在浏览器的新标签页中打开.

Never done this before so not sure what is involved in it. I did search and found many answers but they were more complex than what I need. For example they needed to zoom in, generate, create accurate thumbnail, embed the actual PDF in the webpage, etc... But my question is much simpler: If my guy that I am showing his information on webpage has some PDF to show I just want to put a generic PDF icon on the page, people click on it and the actual PDF opens in a new tab in their browser.

这样做会涉及到什么? 它不像文件路径，PDF作为二进制对象保存在SQL Server中，或者将其保存在SQL Server中.它不是服务器上的文件磁盘路径

What is involved in just doing that? It is not like a file path, the PDF is saved in SQL server as binary objects or whatever it does to save it in SQL Server..it is not a file disk path on server

推荐答案

您的标记表示asp.net-mvc.

Your tags indicate asp.net-mvc.

创建一个控制器来处理对PDF文件的请求

Create a controller to handle requests for the PDF file

伪:

[RoutePrefix("Pdf")]
public class PdfController : Controller {
    [Route("{id}"]
    public ActionResult GetPDF(int id) {    
        //...Code to extract pdf from SQLServer and store in stream
        Stream stream = GetDataFromSQLServerById(id);
        return File(stream,"filename.pdf");
    }
}

在客户端上

<a href="/Pdf/123456" target="_blank">
    <img src="images/pdficon.jpg">
</a>

anchor标签上的target属性将告诉浏览器在新标签页中打开链接.

The target attribute on the anchor tag is what will tell the browser to open the link in a new tab.
