OkHttp proxy settings

I have to setup a proxy to send a JSON using POST, using proxyHost and proxyPort.

public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  Proxy proxyTest = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("proxy", proxyPort));

  OkHttpClient client = new OkHttpClient()
  .proxy(proxyTest)
  .build();
  //OkHttpClient.Builder builder = new OkHttpClient.Builder();
  //builder.proxy(proxySAP);
  //client.setProxy(proxySAP)
  //OkHttpClient client = builder.build();;

  String post(String url, String json) throws IOException {

    RequestBody body = RequestBody.create(JSON, json);
    Request request = new Request.Builder()
        .url(url)
        .post(body)
        .build();
    try (Response response = client.newCall(request).execute()) {
      return response.body().string();
    }
  }

When i try to use the proxyTest that I've saw on some answers here it points an error:

The method proxy() in the type OkHttpClient is not applicable for the arguments (Proxy)

Iam using the OKHTTP 3.3.1(okhttp3)

My question is, what should I do? I did some tests like this:

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

But nothing works so far.

Thanks for your time!

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

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();
