Autodesk forge 查看器 pdf 错误

Question

我正在努力在 forge 查看器中查看 pdf。所有其他图纸 .rvt .dwg .dxf .nwd 都可以正常显示。

最初我收到一个错误

无法读取未定义的属性“loadFromZip”

通过将“loadOptions”添加到我发送给查看器的模型选项中，设法避免了这一点。但现在我从查看器返回错误 6，这是一个服务器错误。请如果有人可以建议该怎么做。

loadModel() {
    var initialViewable = viewables[indexViewable];
    var svfUrl = lmvDoc.getViewablePath(initialViewable);
    var modelOptions = {
        sharedPropertyDbPath: lmvDoc.getPropertyDbPath(),
        loadOptions: {}
    };
    viewer.loadModel(
        svfUrl,
        modelOptions,
        this.onLoadModelSuccess,
        this.onLoadModelError
    );
}

提前致谢

您必须使用ViewingApplication 而不是Viewer3D 或GuiViewer3D 来初始化查看器以查看PDF 文件，因为ViewingApplication 会自动设置一些额外的PDF 配置值。

=== 通过ViewingApplication 将配置传递给Viewer 实例的示例===

//--- Method 1:
var viewerConfigs = {
    extensions: ['MyAwesomeExtension'],
    extOpts: {
        MyAwesomeExtension: {
             buttonColor: 'red'
        }
    }
};
var viewerApp = new Autodesk.Viewing.ViewingApplication('MyViewerDiv');
viewerApp.registerViewer(viewerApp.k3D, Autodesk.Viewing.Private.GuiViewer3D, viewerConfigs);

// In the constructor of the MyAwesomeExtension
class MyAwesomeExtension extends Autodesk.Viewing.Extension {
  constructor( viewer, options ) {
    super( viewer, options );

    // your options here
    const opts = options.extOpts.MyAwesomeExtension;
  }
}

//--- Method 2:
// After model was loadded,
var viewer = viewerApp.getCurrentViewer();
var extOpts = {
   opt1: true
};
viewer.loadExtension( 'Autodesk.ADN.MyExtension', extOpts );
