getToken errors

[Assignment2015]

Hi,
When I am trying to use this api, I encounter some problems about 'getToken'. The error is shown below.

Please give me some suggestions, thank you.

Did you fill up credentials.js with your API keys?

That page is public, so you may not want to share your API keys publicly here... now you just posted your keys, so everybody will be able to use the service on your behalf. You need to delete your App and create a new one to get new keys. Never share your API keys.

Did you try the curl command described on https://developer.autodesk.com/api/view-and-data-api/ (step2) from the command line?

It looks like your http request fails very early, are you restricted by some firewall?

Thanks for the reminding.
Yes, I have run the curl command described on https://developer.autodesk.com/api/view-and-data-api/ (step2) from the command line, and get the token.
Should I put the token somewhere in the file?

Running curl was just to make a test, you should not have to put the token anywhere, this should be retrieved from the http call. You need to sort out why your server is not returning a response when invoking the token API. What is going on when typing "http://localhost:3000/api/token" in the browser? Are you able to debug the server (for example if you use an IDE like WebStorm which allows node debugging) ...?
