推荐答案

你好，



看看Mozilla的PDF.js

http://mozilla.github.io/pdf .js / [ ^ ]



这是一个非常简单的例子：

https://github.com/mozilla/pdf.js/tree/master/examples/helloworld [ ^ ]

Hello,

Have a look at PDF.js from Mozilla
http://mozilla.github.io/pdf.js/[^]

And here is a very simple example:
https://github.com/mozilla/pdf.js/tree/master/examples/helloworld[^]

/* -*- Mode: Java; tab-width: 2; indent-tabs-mode: nil; c-basic-offset: 2 -*- */
/* vim: set shiftwidth=2 tabstop=2 autoindent cindent expandtab: */
//
// See README for overview
//
'use strict';
//
// Fetch the PDF document from the URL using promises
//
PDFJS.getDocument('helloworld.pdf').then(function(pdf) {
// Using promise to fetch the page
pdf.getPage(1).then(function(page) {
var scale = 1.5;
var viewport = page.getViewport(scale);
//
// Prepare canvas using PDF page dimensions
//
var canvas = document.getElementById('the-canvas');
var context = canvas.getContext('2d');
canvas.height = viewport.height;
canvas.width = viewport.width;
//
// Render PDF page into canvas context
//
var renderContext = {
canvasContext: context,
viewport: viewport
};
page.render(renderContext);
});
});

您可以通过iframe使用Google Doc Viewer并指定要显示的PDF文件。这是你应该添加的代码：

You could use Google Doc Viewer through an iframe and specify the PDF file you want to display. This is the code you should add:

<iframe src="http://docs.google.com/gview?url=YOUR_ABSOLUTE_URL_TO_THE_PDF_FILE_HERE&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>

然后你只需要将自己的文档文件设置为url查询字符串para m就是这样！

Then you just need to set up your own document file to the "url" query string param and that's it!

byte[] bts = System.IO.File.ReadAllBytes(filename);
       Response.Clear();
       Response.ClearHeaders();
       Response.ContentType = "application/pdf";
       Response.WriteFile(filename);
       Response.Flush();
       Response.End();
