Question

I’m trying to upload a photo on Facebook using Javascript SDK.
In particular I generate a base64 encoded bytearray from my Actionscript3 app, I pass it to Javascript file using ExternalInterface, and from that I decode the bytearray and I try to upload to FB. But it give me this error:

{"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}

I tried to upload an image simply from url, and in that way it goes well!

This is my Javascript code:

    upPhoto:function(photo) {
       var img = F.decode_base64(photo);

       FB.api('/me/photos', 'post', {
        message:'test',
        fileName:'test',
        image: img
       }, function(response){

          if (!response || response.error) {
            log('Error!');
          } else {
            log('Upload OK!');
          }
       });  
    }

    decode_base64:function(s) {
       var e={},i,k,v=[],r='',w=String.fromCharCode;
       var n=[[65,91],[97,123],[48,58],[47,48],[43,44]];

       for(z in n){for(i=n[z][0];i<n[z][1];i++){v.push(w(i));}}
       for(i=0;i<64;i++){e[v[i]]=i;}

       for(i=0;i<s.length;i+=72){
          var b=0,c,x,l=0,o=s.substring(i,i+72);
          for(x=0;x<o.length;x++){
            c=e[o.charAt(x)];b=(b<<6)+c;l+=6;
            while(l>=8){r+=w((b>>>(l-=8))%256);}
          }
       }
      return r;
    }

I’m not sure where you got that parameters list from, but according to the documentation there’s no fileName nor image, you should use source which is required.

Another thing is that you need to post this as multipart/form-data, which you don’t.
