SENDING BASE64 ENCODING WITH JSON HOW TO

I will be very grateful if you can tell me how to fix this. The JSON would have an image property - which represents some textual representation of the image that we want to send. But I can't get the resulting string from FileReader object.

I need to create the ability to attach pictures and send them via JSON in base64. When receiving the JSON, I first parse it to access the dictionary again like so: jsonRes JSON.parse(xhr.responseText) img jsonRes. Attach image and send it via json in base64 encoding. However, this particular call send the results back as a BASE64 encoded string. I cannot pre-define struct for that and a custom MarshalJson function because this object actually was not initiated by me but decoded from another data format (cbor) then it’s structure may vary. After converting it to JSON via json.dumps(res), I send it via the API to my JavaScript Client. One of the functions is a exportresponses call.

I knew that by default Array and slice values encode as JSON arrays, except that byte encodes as a base64-encoded string, and a nil slice encodes as the null JSON value.īut I’d like to print these byte array in hex string instead of base64 (because it’s more farmilliar for a blockchain address/tx). I’m trying to marshal an interface object to json format and print it to a nicer view, it’s almost OK except for byte array.
