Facebook Graph API - upload photo using JavaScript

Question

Is it possible to upload a file using the Facebook Graph API using javascript, I feel like I'm close. I'm using the following JavaScript

var params = {};
params['message'] = 'PicRolled';
params['source'] = '@'+path;
params['access_token'] = access_token;
params['upload file'] = true;

function saveImage() {
    FB.api('/me/photos', 'post', params, function(response) {
        if (!response || response.error) {
            alert(response);
        } else {
            alert('Published to stream - you might want to delete it now!');
        }
    }); 
}

Upon running this I receive the following error...

"OAuthException" - "(#324) Requires upload file"

When I try and research this method all I can find out about is a php method that apears to solve this

$facebook->setFileUploadSupport(true);

However, I am using JavaScript, it looks like this method might be to do with Facebook Graph permissions, but I already have set the permissions user_photos and publish_stream, which I believed are the only ones I should need to perform this operation.

I have seen a couple of unanswered questions regarding this on stackoverflow, hopefully I can explained myself enough. Thanks guys.

Answer 1

Yes, this is possible, i find 2 solutions how to do that and they are very similar to each other, u need just define url parameter to external image url

FIRST one using Javascript SDk:

var imgURL="http://farm4.staticflickr.com/3332/3451193407_b7f047f4b4_o.jpg";//change with your external photo url
FB.api('/album_id/photos', 'post', {
    message:'photo description',
    url:imgURL        
}, function(response){

    if (!response || response.error) {
        alert('Error occured');
    } else {
        alert('Post ID: ' + response.id);
    }

});

and SECOND one using jQuery Post request and FormData:

 var postMSG="Your message";
 var url='https://graph.facebook.com/albumID/photos?access_token='+accessToken+"&message="+postMSG;
 var imgURL="http://farm4.staticflickr.com/3332/3451193407_b7f047f4b4_o.jpg";//change with your external photo url
 var formData = new FormData();
 formData.append("url",imgURL);

  $.ajax({
                    url: url,
                    data: formData,
                    cache: false,
                    contentType: false,
                    processData: false,
                    type: 'POST',

                    success: function(data){
                        alert("POST SUCCESSFUL");
                    }
                });
