How to login through api from Google Script?

I'm now working on the api of Gatecoin and want to get my open order on Google Sheet. I'm trying this:
function GetOrder() {
var method = "GET"
var URL = "https://api.gatecoin.com/Trade/Orders"
var contentType = "application/json"
var d = new Date()
var now = d.getTime()
var msg = method + URL + contentType + now
var publicKey = :Public_key
var privateKey = :Private_key
var hash = Utilities.computeHmacSha256Signature(msg, privateKey, Utilities.Charset.US_ASCII);
var hashInBase64 = Utilities.base64Encode(hash);
var options ={
'contentType': 'application/json',
'method': method,
'API_PUBLIC_KEY': publicKey,
'API_REQUEST_SIGNATURE': hashInBase64,
'API_REQUEST_DATE': now
};
var rdata = UrlFetchApp.fetch("https://api.gatecoin.com/Trade/Orders", options)
}
But the response mentions I was not logged in. What am I doing wrong?

I believe your options should have headers defined in an object as such:
var options ={
“contentType”: “application/json”,
“method”: method,
“headers”: {
“API_PUBLIC_KEY”: publicKey,
“API_REQUEST_SIGNATURE”: hashInBase64,
“API_REQUEST_DATE”: now
}
};

Node.JS and Object.Keys with json

The Code:
(URL is a working rest api that passes json data)
var request = require('request');
var username = "user";
var password = "pass";
var auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
var url = "URL";
request(
{
method: "GET",
url : url
},
function (error, response, data) {
console.log(data);
var initial_index = Object.keys(data.sites)[0];
var product_index = Object.keys(data.sites[initial_index].products)[0];
var order_id = data.purchase_id;
var title = data.sites[initial_index].products[product_index].title;
var content = data.sites[initial_index].products[product_index].description;
var image = data.sites[initial_index].products[product_index].image;
var total_price = data.sites[initial_index].prices.final_price;
var quantity = data.sites[initial_index].products[product_index].input_fields.quantity;
var sold_by = data.sites[initial_index].info.name;
var order_status = data.sites[initial_index].status;
var datatwo = {
"status": "published",
"order_id": order_id,
"title": title,
"content": content,
"image": image,
"final_price": total_price,
"quantity": quantity,
"sold_by": sold_by,
"order_status": order_status
};
}
);
I receive this error when running the code. How can it be resolved?
var initial_index = Object.keys(data.sites)[0];
^
TypeError: Cannot convert undefined or null to object

You're not parsing the JSON (which is text) you get back. Add this at the top of your request callback:
data = JSON.parse(data);
E.g.:
request(
{
method: "GET",
url : url
},
function (error, response, data) {
data = JSON.parse(data);
var initial_index = Object.keys(data.sites)[0];
// ...
One you've parsed it, you'll have an object tree you can traverse.

Undefined Error when parsing JSON in google apps script

I'm trying to parse JSON I recieved from an API call, but I keep running into the error "TypeError: Cannot read property "id" from undefined. (line 42, file "")" I'm relatively new to Apps Script. Any ideas on what's going on? I can get the payload back in JSON, but can't seem to parse it.
function getInfo() {
var url = "https://subdomain.chargify.com/subscriptions.json";
var username = "xxx"
var password = "x"
var headers = {
"Authorization": "Basic " + Utilities.base64Encode(username + ':' + password)
};
var options = {
"method": "GET",
"contentType": "application/json",
"headers": headers
};
var response = UrlFetchApp.fetch(url, options);
var data = JSON.parse(response.getContentText());
Logger.log(data);
var id = data.subscription; // kicks back an error
// var id = data; works and returns the whole JSON payload
var ss = SpreadsheetApp.getActiveSheet()
var targetCell = ss.setActiveSelection("A1");
targetCell.setValue(id);
}

According to the documentation here
https://docs.chargify.com/api-subscriptions#api-usage-json-subscriptions-list
it returns an array of subscriptions when you call the /subscriptions.json endpoint. So probably your data object should be handled like:
for (var i=0;i<data.length;i++) {
var item = data[i]; //subscription object, where item.subscription probably works
Logger.log(JSON.stringify(item));
}

function getInfo() {
var url = "https://subdomain.chargify.com/subscriptions.json";
var username = "xxx"
var password = "x"
var headers = {
"Authorization": "Basic " + Utilities.base64Encode(username + ':' + password)
};
var options = {
"method": "GET",
"contentType": "application/json",
"headers": headers
};
var response = UrlFetchApp.fetch(url, options);
var data = JSON.parse(response.getContentText());
for (var i = 0; i < data.length; i++) {
var item = data[i]; //subscription object, where item.subscription probably works
Logger.log(JSON.stringify(item));
var subscriptionid = item.subscription.id;
}
var ss = SpreadsheetApp.getActiveSheet()
var targetCell = ss.setActiveSelection("A2");
targetCell.setValue(subscriptionid);
}

Microsoft OAuth does not return refresh_token

33I issued the following request to Microsoft to get the AuthCode,
public ActionResult ConnectMicrosoft()
{
var ClientId = "xxxxxxxxx";
// var ClientSecret = "xxxxxxxxxxxxxxx";
var RedirectUri = "http://www.domain.com:50952/Settings/MicrosoftAuthCallback";
var MsUrl = String.Format("https://login.live.com/oauth20_authorize.srf?client_id={0}&scope=wl.basic&response_type=code&redirect_uri={1}", ClientId, RedirectUri);
return Redirect(MsUrl);
}
and this during the callback,
public ActionResult MicrosoftAuthCallback(string code)
{
string result = null;
var ClientId = "xxxxxxxxxxxx";
var ClientSecret = "xxxxxxxxxxxxxxxxxxxxxxx";
var RedirectUri = "http://www.domain.com:50952/Settings/MicrosoftAuthCallback";
var FinalUri = String.Format("https://login.live.com/oauth20_token.srf?client_id={0}&client_secret={1}&code={2}&grant_type=authorization_code&redirect_uri={3}", ClientId, ClientSecret, code, RedirectUri);
HttpWebRequest _Request = HttpWebRequest.Create(FinalUri) as HttpWebRequest;
_Request.Method = "GET";
using (WebResponse _Response = _Request.GetResponse())
{
var sr = new StreamReader(_Response.GetResponseStream());
result = sr.ReadToEnd();
sr.Close();
}
var _Serializer = new JavaScriptSerializer();
var TokenData = _Serializer.Deserialize<MicrosoftToken>(result);
return View();
}
The callback method successfully returns the access_token, tokentype and expires_in and authentication_token, but refresh token is missing. Could you give me a clue on what i'm doing wrong?

huh, forgot to include the scope, wl.offline_access, also request must b POST with ContentType = "application/x-www-form-urlencoded"

Get signed_request in Node.js (Express) Facebook canvas app

is there any way how to get and parse signed_request in Node.js Facebook page tab app? I need to know page id and if user liked the page...

I did this a little while ago, and ended up writing a small library to do it. The original CoffeeScript can be found at https://gist.github.com/fbef51815ab6f062b51a#file_signed_request.coffee, here is a JavaScript translation:
var crypto = require('crypto');
SignedRequest = (function() {
function SignedRequest(secret, request) {
this.secret = secret;
this.request = request;
this.verify = this.verify.bind(this);
var parts = this.request.split('.');
this.encodedSignature = parts[0];
this.encoded = parts[1];
this.signature = this.base64decode(this.encodedSignature);
this.decoded = this.base64decode(this.encoded);
this.data = JSON.parse(this.decoded);
}
SignedRequest.prototype.verify = function() {
if (this.data.algorithm !== 'HMAC-SHA256') {
return false;
}
var hmac = crypto.createHmac('SHA256', this.secret);
hmac.update(this.encoded);
var result = hmac.digest('base64').replace(/\//g, '_').replace(/\+/g, '-').replace(/\=/g, '');
return result === this.encodedSignature;
};
SignedRequest.prototype.base64encode = function(data) {
return new Buffer(data, 'utf8').toString('base64').replace(/\//g, '_').replace(/\+/g, '-').replace(/\=/g, '');
};
SignedRequest.prototype.base64decode = function(data) {
while (data.length % 4 !== 0) {
data += '=';
}
data = data.replace(/-/g, '+').replace(/_/g, '/');
return new Buffer(data, 'base64').toString('utf-8');
};
return SignedRequest;
})();
module.exports = SignedRequest;
Which you can use like this:
var verifier = new SignedRequest(clientSecret, signedRequest);
verifier.verify() // whether or not the signed request verifies
verifier.data // the data from the signed request
