Sending Binary Data over the Network with Json

First, you need to open the file. Since the file is binary, you have to open it with an additional “b” flag.

Here i am sending a zip file

f ="path/", "rb")

Next, you have to do binary-to-text encoding on the binary file because the JSON  will complain if you try to feed it a binary string. To overcome this obstacle, you need to apply Base64 encoding.

file_content = Base64.b64encode(

After you have a text representation of the data, you can then use JSON to package it, you can use to_json to convert in to json


In your  Rails application you can do this like

render :layout=>false , :json => {:file=> file_content}.to_json
