我正在尝试使用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>
我把pdf的url改成了本地的'/test.pdf'，但是它提示找不到文件，明明在我的根目录下。你知道这个错误可能是什么原因吗？
