a snippet that gets the query params for an Agora token server.

getQueryParams.js

  // get uid 
  let uid = req.query.uid;
  if(!uid || uid == '') {
    uid = 0;
  }
  // get role
  let role = RtcRole.SUBSCRIBER;
  if (req.query.role == 'publisher') {
    role = RtcRole.PUBLISHER;
  }
  // get the expire time
  let expireTime = req.query.expireTime;
  if (!expireTime || expireTime == '') {
    expireTime = 3600;
  } else {
    expireTime = parseInt(expireTime, 10);
  }
  // calculate privilege expire time
  const currentTime = Math.floor(Date.now() / 1000);
  const privilegeExpireTime = currentTime + expireTime;
