OkHttp how to log request body

Nikola's answer did not work for me. My guess is the implementation of ByteString#toString() changed. This solution worked for me:

private static String bodyToString(final Request request){    try {        final Request copy = request.newBuilder().build();        final Buffer buffer = new Buffer();        copy.body().writeTo(buffer);        return buffer.readUtf8();    } catch (final IOException e) {        return "did not work";    }}

From the documentation of readUtf8():

Removes all bytes from this, decodes them as UTF-8, and returns the string.

which should be what you want.

I tried to comment on the correct answer from @msung, but my reputation isn't high enough.

Here's modification I did to print RequestBody before making it a full request. It works like a charm. Thanks

private static String bodyToString(final RequestBody request){        try {            final RequestBody copy = request;            final Buffer buffer = new Buffer();            copy.writeTo(buffer);            return buffer.readUtf8();        }         catch (final IOException e) {            return "did not work";        }}

EDIT

Because I see there is still some people interested by this post, here is the final version (until next improvement) of my log interceptor. I hope it will save some of you guys's time.

Please note that this code is using OkHttp 2.2.0 (and Retrofit 1.9.0)
