OkHttp proxy settings

Found the solution:

  OkHttpClient client = new OkHttpClient.Builder().proxy(proxyTest).build();

If we use the builder to input the proxy, it will work like a charm =D

okhttp version:3.11.0. SOCKS proxy example

String hostname = "localhost"/*127.0.0.1*/;
int port = 1080;
Proxy proxy = new Proxy(Proxy.Type.SOCKS,
        new InetSocketAddress(hostname, port));

OkHttpClient client = new OkHttpClient.Builder()
        .proxy(proxy)
        .build();

SOCKS5 Auth example

I think it's the easiest working soulution. But it seems to me that it can be not 100% safe. I took this code from this code from here and modified it because my proxy's RequestorType is SERVER. Actually, java has a strange api for proxies, you should to set auth for proxy through system env ( you can see it from the same link)

final int proxyPort = 1080; //your proxy port
final String proxyHost = "your proxy host";
final String username = "proxy username";
final String password = "proxy password";

InetSocketAddress proxyAddr = new InetSocketAddress(proxyHost, proxyPort);
Proxy proxy = new Proxy(Proxy.Type.SOCKS, proxyAddr);

Authenticator.setDefault(new Authenticator() {
  @Override
  protected PasswordAuthentication getPasswordAuthentication() {
    if (getRequestingHost().equalsIgnoreCase(proxyHost)) {
      if (proxyPort == getRequestingPort()) {
        return new PasswordAuthentication(username, password.toCharArray());
      }
    }
    return null;
  }
});


OkHttpClient client = new OkHttpClient.Builder()
        .proxy(proxy)
        .build();
