Using Facebook API to login

Fri Jun 05, 2015 7:59 pm

Hi!

Could you clarify me?

I deployed the facebook API in my app and it works. I used the facebook data to register the user in my User collection.

Now, I want to use Facebook API to user login in my app and I don't know what I need to do. I want that always when the user click to enter in my app, my app don't ask his/her login or he/she needs to click "connect with facebook" again. Everything needs to be automatic.

I read the facebook instruction (https://developers.facebook.com/docs/...). I think that Facebook API with Appery.io sends me the access token short-term. Now, what do I need to do?

Thanks for helping me!

Hello Leonardo,

You should get user name, email or id from facebook (it depends on what do you need) and save it to storage variable.

Every other application start send this variable to appery login service.

Thanks Sergiy!!

I was trying to develop the code. I got the data's user (user name, email, etc) but I need to change the short access token to long access token as described in the facebook tutorial bellow.

How can I make a GET call from server-side? I created a service but I think 1) this service isn't from server-side and 2) this call doesn't accept JSON response as images bellow.

Could you help me?

Thanks a lot!

OK Alena.

Let me try modify the question to our scenario.

How can I make a GET call with javascript in server code and get the response of the call?

I tryed using the code bellow but without success.

code
var url = "https://graph.facebook.com/oauth/access_token&quot
var params = "somevariable=somevalue&anothervariable=anothervalue&quot
var http = new XMLHttpRequest();

http.open("GET", url+"?"+params, true);
http.onreadystatechange = function()
{
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(null);
/code

Error:
code
Script facebook_long_term: ReferenceError: XMLHttpRequest is not defined ( @ 13 : 15 ) -> var http = new XMLHttpRequest();
/code
