JavaScript Node.js Basics (2014) Building a Command Line Application Handling Parsing and Status Code Errors

Why am I not getting the same result?

WHy am I not getting the same result ? Any help is greatly appreciated

//Problem : We need a simple way to look at a users badge count and JS points

//Solution : use node.js to connect to Trehouses API to get profile information to print out


var https = require("https")
var username = "bryanwoodard111";

//print out message
function printMessage(username, badgeCount, points){
  var message = username + " has " + badgeCount + " total badges and " + points + " total points in JavaScript";
  console.log(message);
}


//Print out error messages
function printError(error){
  console.error(error.message);
}




//Connect to the API url (https://teamtreehouse.com/username.json)
var request = https.get("https://teamtreehouse.com/" + username + ".json", function(response){
  var body = "";
  //Read the data
  response.on("data", function(chunk){
    body += chunk;
  });

  response.on("end", function(){
    if (response.statusCode === 200){
      try{
        var profile = JSON.parse(body);
        printMessage(username, profile.badges.length, profile.points.JavaScript);
      }catch(error){
        //Parse error
         printError(error);
      }
    } else {
      //status code error
      printError({message: "there was an error getting the profile for " + username + " . (" + https.STATUS_CODES[response.statusCode] + ")"});
    }
  });
  //Parse and Print Data
});


//Connection Error 
request.on("error", printError);

Hey Bryan,

Your username is wrong; it's actually bryanwoodard. Also, the https module doesn't have a STATUS_CODES object. That line should read:

printError({ message: "there was an error getting the profile for " + username + " . (" + response.statusCode + ")" });

Thanks
