 ...... ECC.... CODE BY KASVOPUS

HOW DO I FIND MY USER ID CODE FROM THIS?

I HAVE TO INTEGRATE THIS?

FB.getLoginStatus(function(response) {
  if (response.status === 'connected') {
    // the user is logged in and connected to your
    // app, and response.authResponse supplies
    // the user’s ID, a valid access token, a signed
    // request, and the time the access token 
    // and signed request each expire
    var uid = response.authResponse.userID;
    var accessToken = response.authResponse.accessToken;
  } else if (response.status === 'not_authorized') {
    // the user is logged in to Facebook, 
    //but not connected to the app
  } else {
    // the user isn't even logged in to Facebook.
  }
});

Perhaps you can try something like

var globalUserID = null;

function loadUser() {
   var url = "https://graph.facebook.com/me?" + mainAccessToken;
   doWebRequest("GET", url, "", parseUser);
}

function parseUser(response) {
   var user = eval("[" + response + "]")[0];
   globalUserID = user.id;    
}

copy this

function loadUser() {
var url = "https://graph.facebook.com/me?" + mainAccessToken;
doWebRequest("GET", url, "", parseUser);
}

function parseUser(response) {
var user = eval("[" + response + "]")[0];
globalUserID = user.id;
}

and in to file "main.qml" i have this
WITH THIS I HAVE TO FIND THE PROFILE IMG'S CONNECTED

Image {
id: image8
x: 0
y: 0
width: 123

visible: true
fillMode: Image.PreserveAspectFit
}

but does not work, what is wrong?
thanks

The version of parseUser doesn't return a value atleast. So if you are are trying to use the return value to get the userid then you should add

return user.id;

to the end of parseUser.

TypeError: Result of expression 'user' [undefined] is not an object.
in this line
globalUserID = user.id;

You shouldn't call parseUser yourself, because it takes the HTTPResponse as parameter which should be given by your doWebRequest function. Instead call loadUser somewhere in your code. Then make sure you have declared

var globalUserID = ""

on top of the JavaScript file. This way you can simply access the userID after loadUser function by Facebook.globalUserID

For example your Image could have.

Image {
    source: "https://graph.facebook.com/" + Facebook.globalUserID + "/picture"
}

QML Image: Error downloading https://graph.facebook.com//picture - server replied: Internal Server Error

I do not understand why it does not work: (
thanks anyway

That happens when the userID is not set yet, before loadUser was called. One work around is the following.

Image {
    source: Facebook.globalUserID == "" ? "" : "https://graph.facebook.com/" + Facebook.globalUserID + "/picture"
}

Which makes the source empty so no image gets loaded until a valid userID gets set.
