How can I configure the username and password to authenticate a http proxy server using Java?
I just found the following configuration parameters:
http.proxyHost=<proxyAddress>
http.proxyPort=<proxyPort>
https.proxyHost=<proxyAddress>
https.proxyPort=<proxyPort>
But, my proxy server requires authentication. How can I configure my app to use the proxy server?
Since no one has mentioned this and I have seen a few examples where Authenticator.setDefault, this can cause unintentionally leaking of your username and password. Here is another way of doing this, I think this is much cleaner.
import java.net.*;
import java.util.Base64;
class JavaFileUtil {
private String hostname = "hostname";
private int port = 8000;
private String username = "username";
private String password = "password";
private Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(hostname, port));
private String authHeader = new String(Base64.getEncoder().encode(new String(username + ":" + password).getBytes()));
public void download(URL url) {
HttpURLConnection newConnection = null;
try {
newConnection = (HttpURLConnection) url.openConnection(proxy);
newConnection.setRequestProperty("Proxy-Authorization", "Basic " + authHeader);
//The rest of your code here
} catch (Exception e) {
//log some error or handle it
} finally {
//Make sure you close the connection
if (newConnection != null) newConnection.disconnect();
}
}
}
