名为 Autodesk.Viewing.Collaboration 的扩展在 Forge Viewer 中无法正常工作？

Question

I normally quoted Autodesk.Viewing.Collaboration in the js file, and I can see the sharing button in the toolbar, but when I clicked to start viewing, the following error message appeared on the page:

Access to XMLHttpRequest at 'https://rtc.api.autodesk.com/socket.io/?sessionID=https://developer.api.autodesk.com/derivativeservice/v2/derivatives/urn:adsk.viewing:fs.file:***/output/&EIO=3&transport=polling&t=1605086974047-0' from origin 'http://example.com:10080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

When I used this function before, it was normal. I can't understand the current situation. Can someone help me answer my doubts? How can I handle this situation instead? And after the sharing behavior is issued, if can I actively control the cancellation of sharing?

Answer 1

Note that this was not a CORS issue. The collaboration service host ( https://rtc.api.autodesk.com ) was temporarily down, and is now back online.
