Question

我尝试按照Autodesk Forge教程制作基本查看器。（参见下面的myCoolViewer.html）

当我在Chrome中打开该html文件时，我在Chrome的控制台中看到以下错误：

image: error in chrome console

html中引用的rvt文件先前已使用

成功加载到存储桶中

developer.api.autodesk.com/oss/v2/buckets/MyCoolBucket/objects/rac_basic_sample_project.rvt

并使用

翻译成SVF格式

developer.api.autodesk.com/modelderivative/v2/designdata/job

经过验证

developer.api.autodesk.com/modelderivative/v2/designdata/the-source-URN,-Base64-encoded/manifest

我很感激任何疑难解答步骤！

Answer 1

似乎您的documentId不适合Forge，documentId应该是您上传的ObjectKey文件的rvt的base64编码字符串，如下所示：

通过here了解更多详情。

你能帮我一个忙，用你的JavaScript代码中的documentId替换你的the-source-URN,-Base64-encoded吗？

希望得到这个帮助。

Answer 2

正如Eason所提到的，documentId需要进行base64编码，并以urn:开头，例如。 "urn:dxgsjsksk......."

来自viewer3D.min.js的Autodesk Forge，DOMException
