Question

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>

所以我将pdf url改为我当地的'/test.pdf'url。然而，这给了我一个消息，当它在我的根文件夹中显然存在时无法找到该文件。知道什么可能导致这个错误吗？

Answer 1

修改pdfjs / web / viewer.js文件并更改

var DEFAULT_URL = '<file path on your server>'

当我尝试在我的本地系统上的http://mozilla.github.com/pdf.js/web/viewer.html实现演示

时，这很有效

pdf.js与本地pdf文件
