Handling Forge Token Expiry

Question: I am working on an app for the Forge and AppStore hackathon challenge.

I am using the online tool for token generation.

However, my access token is getting expired.

Please help resolve the issue.

Answer by Cyrille Fauvel: is a web site which demonstrates how to easily translate a model using your own consumer and secret key.

It is not intended to be used as an access token generator, because it is highly discouraged to transmit your keys over Internet, even through an encrypted and secured https connection.

Instead, you should write your own code to generate the access token yourself, just like does. The relevant part is located in lmv-token.js around line 43.

As you have noticed, the token expires after a while.

This sample does not take care of refreshing it, as this site is to be used manually for a single translation.

In your own implementation, you will need to check the expires_in field to know when the token will expire and make sure to refresh it before it does so as shown in lmv-token.js around line 29.

Thank you, Cyrille, for the complete and succinct answer.
