Upload a photo to facebook album

I have a nodejs (+express + mongodb,gridstore) backend, and want to upload a photo to a facebook album.

I came across 2 methods. the first ( https://developers.facebook.com/blog/post/526/ ) needs to get the full url resource of my picture, which I don't have as it is data that I pull from gridstore, and the second ( https://developers.facebook.com/docs/reference/api/album/ ) is very poorly documented, via the Graph API, where I can't figure out what my request should look like. (the form-data, what fields should it have, how to convert my data blob\stream from gridstore to it)

Here is what I currently have, and doesn't work:

facebook.uploadPhoto = function (token, albumId, photo, callback) {
    var fb = fermata.json('https://graph.facebook.com/' + albumId);
    fb.photos({access_token:token}).post({'Content-Type':"multipart/form-data"}, {source:{data:photo}}, callback);
};

Any help would be much appreciated

There is a good chance the file is not properly serialized. Fermata will take a node File buffer via data. Have you tried passing that instead? 

fs.readFile("/path/to/photo.jpg", function (err, data) {
  fermata.json("https://graph.facebook.com/graph/api").post({"Content-Type":"multipart/form-data"},  {fileField:  {data:data, name:"", type:""}  }, callback);
});

Adding your access token etc..

I solved this problem by using a simple POST to the facebook graph API using the poster module.

var options = {
  uploadUrl: 'https://graph.facebook.com/'+user+'/photos?access_token='+accessToken,
  method: 'POST',
  fileId: 'source',
  fields: {'message':''} // Additional fields according to graph API
};

var fileName = ''; // Local or remote url where to find the image
poster.post(fileName, options, function(err, data) {
  if (err) {
    //Something went wrong
  } else {
    // Everything ok
  }
});

Honestly, I've got limited experience working with the Facebook graph API and mostly using PHP and Java.

Here is some streams that you might find helpful:

Basically, I recommend you punt a little in your implementation and code it in the following way:

  1. Create a REST web service function call in Node.js to output a single image from gridstore using an internal UID.
  2. Code your uploadToFacebook function to use an image URL that calls the REST web service function.

Basically, this would allow you to validate the image output by pointing your browser to the REST web service and avoid any blob\stream conversions inside your uploadToFacebook function. I'm assuming you store the image in gridstore vs. mongodb.

hope that helps...
