使用loopj时出错：“找不到用于认证路径的信任锚。”

Question

Currently I am working on a project, on which I need to GET/PUT data from a web server with basic authentication on Android.

I followed the instructions of http://loopj.com/android-async-http/ but I encountered

"Caused by: java.security.cert.CertificateException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found."`

The method on the website above is to make use of HttpClient which is deprecated now. I know there is HttpURLConnection , but I cannot find a suitable tutorial for my purpose.

Answer here: Http Basic Authentication in Java using HttpClient?

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64Encoder.encode ("test1:test1");

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}
