facebook oauth, no picture with basic permissions - facebook

Question

I'm using oauth to log facebook users in to my app. I'm testing with my FB account and with the basic permissions scope. Facebook docs say that I should be able to get 'picture' with basic permissions, but my account has no 'picture' property when I access it with the API. First name, last name, etc. are there though.
Is this because my account is not publicly viewable? Why might this happen? I definitely have a profile picture attached.

Answer 1

best way is to keep the basic permissions and fire the request for the image in a separate step. Ask the graph api in this way:
https://graph.facebook.com/[fb_user_id]?fields=picture.type(small)
larger image:
https://graph.facebook.com/[fb_user_id]?fields=picture.type(large)
You will get a JSON response like:
{
"id": "100001XXXXXXXXX",
"picture": {
"data": {
"url": "http://profile.ak.fbcdn.net/hprofile-XXXX/41524_1000018XXX51507_XXXX3_q.jpg",
"is_silhouette": false
}
}
}

Answer 2

You can derive the profile photo URL directly from the basic standard OAuth info returned from facebook as Josh Nankin noted, BUT with a clarification.
You can still use the user's ID returned to request the photo, for example:
https://graph.facebook.com/914431778578699/picture?type=large
is the same as
https://graph.facebook.com/dark.eye.1/picture?type=large
This way only one request must be made, because you can interpolate the photo URL as you store it in the DB.

Answer 3

So, still not sure why the graph api does not return a picture property when you hit the /me path on the API, but once you have the username from /me, you can get the picture pretty easily at:
https://graph.facebook.com/USERNAME/picture

Answer 4

https://developers.facebook.com/docs/reference/api/user/:
“picture: The URL of the user's profile pic (only returned if you explicitly specify a 'fields=picture' param)”
You haven’t probably overlooked the part marked in bold …?

Answer 5

Actually you don't need to allow public access to get the profile picture since you can get the USER_ID. Though the USER_ID you can navigate to the profile picture easily.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
console.log('Welcome! Fetching your information.... ');
var url = '/me?fields=id,name';
FB.api(url, function(response) {
var linkpp = 'https://graph.facebook.com/' + response.id + '/picture?type=large';
document.getElementById("id_of_link_tag").href = linkpp;
});
});
}
You can change the type in variable linkpp to type=small which returns a low resolution image.
var linkpp = 'https://graph.facebook.com/' + response.id + '/picture?type=small';
