currently trying to develop one of my first alexa skills. trying to build a skill that updates the user on who out of their Steam friends, are online.
Curerntly it's pretty messy and not in the format i hope it to be in the end, but for testing purposes, I'm not yet using intents, im just testing using the launchrequest.
So far I've managed to get a users (mine) friends list from steam and put all the friends ids in a url that should be able to grab the details for these users. The issue I'm having is performing the second API call to grab the players details using the steamIds. i keep getting an 'undefined' return and am stumped on what i'm doing wrong. I'm very much new to JS so there's bound to be mistakes in here, but i can work on tidying up later once i've got it working.
This works fine
/**
* Called when the user invokes the skill without specifying what they want.
*/
function onLaunch(launchRequest, session, callback) {
console.log("onLaunch requestId=" + launchRequest.requestId
+ ", sessionId=" + session.sessionId);
var cardTitle = "Hello, World!"
testGet(function (response) {
var speechOutput = "Here is the result of your query: " + response;
var shouldEndSession = true;
callback(session.attributes,
buildSpeechletResponse(cardTitle, speechOutput, "", true));
});
//var speechOutput = "You can tell Hello, World! to say Hello, World!"
//callback(session.attributes,
// buildSpeechletResponse(cardTitle, speechOutput, "", true));
}
This is the function that is grabbing the details from my friendlist
function testGet(response) {
var http = require('http')
var url = " http://api.steampowered.com/ISteamUser/GetFriendList/v0001/?key=XXXXXXXXXX&steamid=76561198068311091&relationship=friend"
http.get(url, function (res) {
// data is streamed in chunks from the server
// so we have to handle the "data" event
var buffer = "",
data,
friendsList,
i,
address,
textResponse,
route;
res.on("data", function (chunk) {
buffer += chunk;
});
res.on("end", function (err) {
// finished transferring data
// dump the raw data
console.log(buffer);
console.log("\n");
data = JSON.parse(buffer);
friendsList = data.friendslist.friends;
textResponse = isOnline(friendsList);
response("Friends online: " + textResponse);
}).on('error', function (e) {
console.log("Error message: " + e.message);
});
})
}
and this is the final function which i'm having difficulties with.
function isOnline(friendsList){
var http = require('http'),
i,
comma,
friendsIDs = "";
// for loop to get all friends ids in string
for (i = 0; i < friendsList.length; i++) {
// if i equals 0 then it is the start of the loop so no
//comma needed, otherwise add a comma to seperate the ids.
if(i === 0) {comma = ""}
else{comma = ","}
//place the ids in a comma seperate string
friendsIDs += comma + friendsList[i].steamid;
}
var playerurl = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=xxxxx&steamids=" + friendsIDs;
// works fine up to this point
// run the api call to get player details
http.get(playerurl, function (response) {
// data is streamed in chunks from the server
// so we have to handle the "data" event
var buffer = "",
playerdata,
returnText,
textResponse,
friendsInformation,
route;
response.on("playerdata", function (chunk) {
buffer += chunk;
});
response.on("end", function (err) {
// finished transferring data
// dump the raw data
console.log(buffer);
console.log("\n");
playerdata = JSON.parse(buffer);
friendsInformation = playerdata.response.players;
for (i = 0; i < friendsInformation.length; i++) {
if(friendsInformation[i].personastate == 1) {
returnText += friendsInformation[i].personaname + " chicken";
}
}
return returnText;
}).on('error', function (e) {
console.log("Error message: " + e.message);
});
});
}
Been going round in circles for hours and feel so close to doing this but have no idea where I'm going wrong?! thanks
