I’ve found through experience that this Java program should work if you are hitting an HTTPS URL that has a valid SSL certificate from someone like Verisign or Thawte, but will not work with other SSL certificates unless you go down the Java keystore road. ClosableHttpClient and we are also using Java 8 lambdas for the ResponseHandler. HttpClient seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and.

I just used this program to troubleshoot a problem with Java and HTTPS URLs, including all that nice Java SSL keystore and cacerts stuff you may run into when working with Java, HTTPS/SSL, and hitting a URL.

Sure, here’s the source code for an example Java HTTPS client program I just used to download the contents of an HTTPS (SSL) URL. In this tutorial, well look at how we can use Apache HttpClient 4 to perform. We'll make use of the client instance to send this request later on. Now we are ready to create an instance of HttpRequest from its builder. It will also automatically downgrade to HTTP/1.1 if the server doesn't support HTTP/2. Handling of request and response bodies as reactive streams. Support for synchronous and asynchronous programming models.
Some of its features include: Support for HTTP/1.1, HTTP/2, and Web Socket. Java HTTPS client FAQ: Can you share some source code for a Java HTTPS client application?
