It is really a hard job to find out how to upload pictures to Facebook. It took days for me to analyze and find-out how one can upload pictures to Facebook with the need of their JavaScript API. Here you go.imageData the variable used here is the base64 format of image.
try{
blob = dataURItoBlob(imageData,mimeType);
}catch(e){console.log(e);}
var fd = new FormData();
fd.append("access_token",accessToken);
fd.append("source", blob);fd.append("message","Kiss");
try{
$.ajax({
url:"https://graph.facebook.com/" + <<userID received on getting user details>> + "/photos?access_token=" + <<user accessToken>>,
type:"POST"
data:fd,
processData:false,
contentType:false,
cache:false,
success:function(data){
console.log("success " + data);
},
error:function(shr,status,data){
console.log("error " + data + " Status " + shr.status);
},
complete:function(){
console.log("Ajax Complete");
}
});
}catch(e){console.log(e);}
function dataURItoBlob(dataURI,mime) {
// convert base64 to raw binary data held in a string
// doesn't handle URLEncoded DataURIs
var byteString = window.atob(dataURI);
// separate out the mime component
// write the bytes of the string to an ArrayBuffer
//var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(byteString.length);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
// write the ArrayBuffer to a blob, and you're done
var blob = new Blob([ia], { type: mime });
return blob;
}
