强制PDF显示内联,即使Content-Disposition另有说明？

Question

我正在从一台服务器中将PDF嵌入到IFRAME中,不幸的是服务它们Content-Disposition:attachment;.

有没有办法强制浏览器显示内联PDF？不幸的是,我无法更改iframe中链接的PDF文件的标题.

您可以使用 pdf.js 库在 html 页面中渲染 pdf。 Mozilla Pdf.js

HTML代码

<!DOCTYPE html>
<html>
 <head>
  <title>PDF.js Learning</title>
 </head>
 <body>
  <script type="text/javascript" src="pdf.js"></script>
  <canvas id="the-canvas"></canvas>

 </body>
</html>

JavaScript 代码

 var url = "www.pdf995.com/samples/pdf.pdf";

 PDFJS.getDocument(url)
  .then(function(pdf) {
   return pdf.getPage(1);
   })
 .then(function(page) {

 var scale = 1.5;


 var viewport = page.getViewport(scale);

 // Get canvas#the-canvas

 var canvas = document.getElementById('the-canvas');

 // Fetch canvas' 2d context

 var context = canvas.getContext('2d');

 // Set dimensions to Canvas

 canvas.height = viewport.height;
 canvas.width = viewport.width;

 // Prepare object needed by render method

  var renderContext = {
 canvasContext: context,
 viewport: viewport
 };

 // Render PDF page

  page.render(renderContext);
 });
