OkHttp API rate limit

Question

Has OkHttp an integrated way of complying with an api rate request limit, or it has to be implemented externally? either case a hint on where to start is appreciated.

Answer 1

An interceptor combined with a RateLimiter from Guava was a good solution to avoid receiving a 429 HTTP code.

Let's suppose we want a limit of 3 calls per second:

import java.io.IOException;

import com.google.common.util.concurrent.RateLimiter;

import okhttp3.Interceptor;
import okhttp3.Response;

public class RateLimitInterceptor implements Interceptor {
    private RateLimiter rateLimiter = RateLimiter.create(3);

    @Override
    public Response intercept(Chain chain) throws IOException {
        rateLimiter.acquire(1);
        return chain.proceed(chain.request());
    }
}
