在 Forge Viewer 上查看原生 PDF 和 DWF，无需翻译 [英] Native PDF and DWF viewing on Forge Viewer without translation
问题描述
我试图在没有 SVF 转换的情况下以本机方式显示 DWF 文件和 PDF 文件.我在这里关注这个博客:
I'm trying to show DWF files and PDF files natively without SVF translation. I'm following this blog here:
https://forge.autodesk.com/blog/dwf-and-pdf-support-forge-viewer
从一个 PDF 示例开始，这是我正在使用的代码(Petr Broz 在其中一篇 stackoverflow 帖子中建议)
Starting with a PDF example, this is the code I'm using (suggested by Petr Broz in one of the stackoverflow posts)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<link rel="stylesheet" href="https://developer.api.autodesk.com/modelderivative/v2/viewers/7.*/style.css">
<style>
body,
html {
margin: 0;
padding: 0;
height: 100vh;
}
#preview {
position: absolute;
width: 100%;
height: 100%;
}
</style>
<title>Autodesk Forge: PDF Demo</title>
</head>
<body>
<div id="preview"></div>
<script src="https://developer.api.autodesk.com/modelderivative/v2/viewers/7.*/viewer3D.js"></script>
<script>
Autodesk.Viewing.Initializer({ accessToken: '' }, async function () {
const viewer = new Autodesk.Viewing.GuiViewer3D(document.getElementById('preview'));
viewer.start();
await viewer.loadExtension('Autodesk.PDF');
viewer.loadModel('https://developer.api.autodesk.com/oss/v2/signedresources/44b4af63-bd11-4a0f-8231-b1cbd14da3d9?region=US');
});
</script>
</body>
</html>这一行:
viewer.loadModel('https://developer.api.autodesk.com/oss/v2/signedresources/44b4af63-bd11-4a0f-8231-b1cbd14da3d9?region=US');
});
显示位于 oss 存储桶中的 pdf 文件的签名 url.这是将文件传递给此方法的正确方法吗?因为我收到以下错误:
shows a signed url of a pdf file that resides in an oss bucket. Is this the correct way to pass the file to this method? because I'm getting the following errors:
你能提出一个解决方案吗?
Could you please suggest a solution?
推荐答案
查看器要求 URL 以特定的文件扩展名结尾，以便它知道要使用哪个加载程序.如您所见，签名网址不包含该信息.
The viewer requires the URL to end with a specific file extension so that it knows which loader to use. And as you can see, signed URLs don't include that info.
您可以通过在签名 URL 末尾将文件扩展名作为附加查询参数传递来解决此问题，例如，如下所示:
You can work around that by passing the file extension as an additional query parameter at the end of of your signed URL, for example, like this:
https://developer.api.autodesk.com/oss/v2/signedresources/44b4af63-bd11-4a0f-8231-b1cbd14da3d9?region=US&format=.pdf
