How to read blob uri?

[neciszhang]

Hi,
I upload a glb file, I use "URL.createObjectURL(file)" to create a uri, WebIO.readAsJSON can't read it.

Is this a .glb file? If you have a File instance already, then accessing it through an ArrayBuffer and parsing that might be the way to go:

const arrayBuffer = await file.arrayBuffer();
const { json, resources } = io.binaryToJSON(arrayBuffer);

If it's a .gltf and already in local memory, then you'll have to construct the JSONDocument yourself in order to parse that. Relative references to textures and .bin files will not work when encoding a blob URI.

Thanks! It's work.
const arrayBuffer = await file.arrayBuffer();
const uint8View = new Uint8Array(arrayBuffer);
const { json, resources } = await io.binaryToJSON(uint8View);
