How to decode base64 to image file in Node.js?
I believe you need to use encodeUriComponent(base64) before sending to server.
try sending a JSON object, and parsing the image on the client side.
For example:
var mimeType = image.split(';')[0];var base64 = encodeUriComponent(image.split(',')[1]);var imageData = { "mimeType" : mimeType, "src" : base64}...xmlhttp.setRequestHeader("Content-type","application/json");xmlhttp.send(imageData);
