Upload multipart image data in JSON with Retrofit?

Question

I would like to do a PUT request with this JSON body (containing a picture) and with Retrofit. I\'m using it under Android:

{
    \"Request\": {
        \"da

You need to put image data in byte by using multipart form data.

try {
    HttpPost httppost = new HttpPost("some url");
    MultipartEntity multipartEntity = 
        new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
    multipartEntity.addPart("Image", new FileBody(image));
    httppost.setEntity(multipartEntity);
    mHttpClient.execute(httppost, new YOURHANDLER());
} catch (Exception e) {
    Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e);
}

To send post request using parameters

HttpPost httpPost = new HttpPost(url);
List nameValuePairs = new ArrayList();

if (values != null) {
    for (Map.Entry entry : values.entrySet()) {
        nameValuePairs.add(
            new BasicNameValuePair(entry.getKey(), entry.getValue()));
    }
    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
}
