HttpsUrlInfo.java - HTTPS URL Information
How to get more information about the HTTP URL object? It is created as "new java.net.URL(...)".
✍: FYIcenter
If you created a URL object with "new java.net.URL(...)",
you can use the sample Java code to get more information about the URL object:
// Copyright (c) FYIcenter.com import java.net.*; import java.io.*; public class HttpsUrlInfo { public static void main(String[] args) throws Exception { URL url = new URL("https://www.oracle.com/"); System.out.println(); System.out.println("URL Information"); System.out.println(" URL Class Name: "+url.getClass().getName()); System.out.println(" URL as String: "+url.toString()); System.out.println(" URL Protocol: "+url.getProtocol()); System.out.println(); System.out.println("Connection Information"); URLConnection con = url.openConnection(); System.out.println(" Connection Class Name: "+con.getClass().getName()); System.out.println(" Connection as String: "+con.toString()); } }
You can compile and run the above example in a command window:
\fyicenter>\local\jdk-1.8.0\bin\javac HttpsUrlInfo.java \fyicenter>\local\jdk-1.8.0\bin\java HttpsUrlInfo URL Information URL Class Name: java.net.URL URL as String: https://www.oracle.com/ URL Protocol: https Connection Information Connection Class Name: sun.net.www.protocol.https.HttpsURLConnectionImpl Connection as String: sun.net.www.protocol.https.DelegateHttpsURLConnection: https://www.oracle.com/
The output confirms that the sun.net.www.protocol.https.HttpsURLConnectionImpl implementation class of the JSSE API is actually used to support HTTPS communication.
You can also specify which implementation class to use with the java.protocol.handler.pkgs system property as shown below:
\fyicenter>\local\jdk-1.8.0\bin\java -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol HttpsUrlInfo URL Information URL Class Name: java.net.URL URL as String: https://www.oracle.com/ URL Protocol: https Connection Information Connection Class Name: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl Connection as String: com.sun.net.ssl.internal.www.protocol.https.DelegateHttpsURLConnection: https://www.oracle.com/
