In the post we’ll show how to leverage auth ptoxy (with login/pass) for JAVA application.
The following code defines Authenticator class that thru the static method setDefault sets authentication for a network connection.
import java.net.Authenticator;
import java.net.PasswordAuthentication;
...
// the `dk.http.auth.tunneling.disabledSchemes` property contains the authentication schemes
// that will be disabled when tunneling HTTPS over a proxy with the HTTP CONNECT method
System.setProperty("jdk.http.auth.tunneling.disabledSchemes", "");
String host = "<host>";
String port = "<port>";
String user = "<login>";
String password = "<pass>";
System.setProperty("https.proxyHost", host);
System.setProperty("https.proxyPort", port);
System.setProperty("http.proxyHost", host);
System.setProperty("http.proxyPort", port);
// The class `Authenticator` represents an object that knows how to obtain authentication for a network connection
Authenticator.setDefault(
new Authenticator() {
@Override
// The method `getPasswordAuthentication` is called when password authorization is needed.
// Subclasses should override the default implementation, which returns `null`
public PasswordAuthentication getPasswordAuthentication() {
if (getRequestorType() == RequestorType.PROXY)
return new PasswordAuthentication(user, password.toCharArray());
return super.getPasswordAuthentication();
}
}
);
