我正在尝试 pdf.js 库，只想在我的服务器上显示本地 pdf 文件，而不是示例提供的 pdf 文件。
<html>
<body>
<canvas id="the-canvas" style="border:1px solid black"></canvas>
<!-- Use latest PDF.js build from Github -->
<script type="text/javascript" src="https://raw.github.com/mozilla/pdf.js/gh-pages/build/pdf.js"></script>
<script type="text/javascript">
//
// NOTE:
// Modifying the URL below to another server will likely *NOT* work. Because of browser
// security restrictions, we have to use a file server with special headers
// (CORS) - most servers don't support cross-origin browser requests.
//
var url = '/test.pdf';
//
// Disable workers to avoid yet another cross-origin issue (workers need the URL of
// the script to be loaded, and dynamically loading a cross-origin script does
// not work)
//
PDFJS.disableWorker = true;
//
// Asynchronous download PDF as an ArrayBuffer
//
PDFJS.getDocument(url).then(function getPdfHelloWorld(pdf) {
//
// Fetch the first page
//
pdf.getPage(1).then(function getPageHelloWorld(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
//
page.render({canvasContext: context, viewport: viewport});
});
});
</script>
</body>
</html>
所以我将 pdf url 更改为我本地的“/test.pdf”url。然而，这给了我一条消息，当它明显位于我的根文件夹中时，它找不到该文件。知道什么可能导致此错误吗？
修改 pdfjs/web/viewer.js 文件并更改
var DEFAULT_URL = '<file path on your server>'
当我尝试在以下位置实现演示时，这有效http://mozilla.github.com/pdf.js/web/viewer.html http://mozilla.github.com/pdf.js/web/viewer.html在我的本地系统上
