Http Client in CLIPS

Here’s the translation of the Go HTTP client example to Java, formatted in Markdown suitable for Hugo:

Our example demonstrates how to create a simple HTTP client using Java’s built-in libraries. We’ll use the java.net.http package, which provides excellent support for HTTP clients in Java 11 and later.

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class HttpClientExample {
    public static void main(String[] args) {
        try {
            // Create an HttpClient object
            HttpClient client = HttpClient.newHttpClient();

            // Build the HTTP GET request
            HttpRequest request = HttpRequest.newBuilder()
                    .uri(URI.create("https://gobyexample.com"))
                    .build();

            // Send the request and get the response
            HttpResponse<String> response = client.send(request, 
                    HttpResponse.BodyHandlers.ofString());

            // Print the HTTP response status
            System.out.println("Response status: " + response.statusCode());

            // Print the first 5 lines of the response body
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(response.body().lines().iterator()));
            for (int i = 0; i < 5 && reader.ready(); i++) {
                System.out.println(reader.readLine());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

In this example, we’re using Java’s HttpClient to issue a simple HTTP GET request.

We first create an HttpClient object, which is similar to the http.DefaultClient in the original example.
We then build an HttpRequest object, specifying the URL we want to GET.
We send the request using the client.send() method, which returns an HttpResponse object.
We print the response status code, which is equivalent to the Status in the original example.
Finally, we read the first 5 lines of the response body. In Java, we use a BufferedReader to read the response body line by line.

To run this program, save it as HttpClientExample.java, compile it, and then run it:

$ javac HttpClientExample.java
$ java HttpClientExample
Response status: 200
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

This Java implementation provides similar functionality to the original example, demonstrating how to make HTTP requests and process responses in Java.
