Can i load the private photos with my webapp from facebook users? - facebook

Question

I have a website and use the login using facebook.
I want to do the following:
User comes to my web site - login with facebook - I read his facebook data and photography permits
For example:
{
"id": "1"
"name": "John English"
"first_name": "John",
"last_name": "English"
"link": "https://www.facebook.com/johnenglish"
"username": "johnenglish"
"gender": "male"
"locale": "en_US"
....
}
and
{
"id": "2"
"name": "John English2"
"first_name": "John",
"last_name": "English2"
"link": "https://www.facebook.com/johnenglish2"
"username": "johnenglish2"
"gender": "male"
"locale": "en_US"
....
}
Both users have a private photo. Can I load the private photos from user (id: 2) with my web application using javascript? Can you give me the example?
I've tried this:
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
FB.api('/USER-ID(USER ID 2)/photos?access_token=' + accessToken, function(response) {
//A user access token is required to request this resource.
});
} else if (response.status === 'not_authorized') {
} else {
}
});
Error: A user access token is required to request this resource.

Answer 1

Have you requested the right permissions when you gained your access token? I don't know how to do it in JS, but you have to tell facebook, that you want you get access to the photos. As I do not work with JS, I request my access token via an URL (see Point 1 here: https://developers.facebook.com/docs/authentication/devices/). In the parameter "scope" you can add the permissions you want to have ( https://developers.facebook.com/docs/authentication/permissions/). Here, you add "&scope=user_photos" (without quotation marks) to the URL.

Answer 2

OK, now I understand your question.
I assume that you already found out the ID of the User 2. I am sorry but I can still not show you how to do it in JS. Though, it may help.
At first, I forgot one permission, you need friends_photos in scope, too.
You now call: http://graph.facebook.com/FRIEND_ID/albums/?access_token=ACCESS_TOKEN.
Type it into your browser, so that you know what I mean: You parse that output and find ids of the albums of your friend.
You get to that album via: http://graph.facebook.com/ALBUM_ID?access_token=ACCESS_TOKEN.
You will find an entry named cover_photo in your output.
Call: http://graph.facebook.com/COVER_PHOTO_ID?access_token=ACCESS_TOKEN and you get access to that photo.
You may now download it via http://graph.facebook.com/COVER_PHOTO_ID/picture?access_token=ACCESS_TOKEN.
Use the URL given in paging -> next to move on to the following photos. It is much easier to follow these steps with a picture in mind, consider that here.
