Q: cesium load gltf model from storage

Question

I am trying to put my .gltf model into a database. I built a restful API to get it from the database. But when I put the URL into Cesium's framework, an error occurs. The error is shown below.

      Sandcastle.addToolbarButton('models', function () {
    // eslint-disable-next-line
    var model = viewer.scene.primitives.add(Cesium.Model.fromGltf({
      id: 'house',
      url: 'http://127.0.0.1:8000/test',
      // url: gltf_data,
      modelMatrix: modelMatrix,
      scale: 0.1
    }))
  }, 'singleModel')

front end javascript code

class Test(flask_restful.Resource):
def get(self):
    client = MongoClient()

    db = client['test']
    fs = gridfs.GridFS(db)
    for x in fs.find():
        data = x.read()
        break
    data = data.decode('utf-8')
    # file = fs.find_one()
    return jsonify(data)

server end python code

Can you share the code that loads this model into Cesium? It looks like you may need to call JSON.parse() to turn the string into an object. — emackey

I fix out by myself, i forget to translate the string to json object, i added a json.loads(data) at server end's code. it runs. Thanks @emackey you give me an advise
