Check Membership of User on Github Teams

checkMembership.js

var https = require('https');

//token from your account to access the GitHub API
var token = "";

var checking = {
  teamID: 1163900, //GCI Students Team for Fossasia
  user: ''
}

//options for the https request
var options = {
  method: 'GET',
  hostname: 'api.github.com',
  path: '/teams/'+checking.teamID+'/memberships/'+checking.user,
  headers: {
    'Authorization': 'token '+token,
    'User-Agent': 'Mozilla/5.0'
  }
};
         
//https request
var req = https.request(options, function(res) {
  var body = '';
  //add the small chunks that node receives to the body variable
    res.on('data', function(chunk) {
      body += chunk;
  });
  
    res.on('end', function() {
      //get the JSON from the returned body string
      var json = JSON.parse(body);
      if(res.statusCode == 200) {
        if(json.state == 'active') {
          console.log("This person is a member of the group.");
        } else {
          console.log("This person is not in the group.");
        }
      } else {
        console.log("You don't have permissions to check for membership.")   
      }
    });
  
});


req.end();

This is very good. I tested it for students team and works perfectly!

Don't do if(json.message != "You must be an organization owner or team maintainer to get a team membership.")

Those messages can change without any warning.

Instead you can do if(res.statusCode==200). 200 is http status for OK as you definitely know. And its a convention that can safely be assumed won't change.

@roonyh Thanks for the tip!
