Java 8: How do I do an API request in Java 8?

[HydrogenOS]

 

Hello,

I am trying to do a API request in Java 8 and the code I am using is for newer versions:

//Classes and Packages Import
package com.malcolmjh.runsafeprofiles.commands;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
//Chat Command Code
public class isprofilesuptodatecommand implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender sender, Command command, String s, String[] args) {
        //Check if the command sender is a player.
        if (sender instanceof Player) {
            Player p = (Player) sender;
            //Check if the command has arguments.
            if (args.length == 0) {
                //If no args return the error
                p.sendMessage(ChatColor.RED + "Unknown or incomplete command, see below for error");
                p.sendMessage(ChatColor.GRAY + "chat" + ChatColor.RED + "<--[HERE]");
                p.sendMessage(ChatColor.DARK_GREEN + "Usage: /chat <message>");
            }else {
                //Make the "name" var Pt1
                StringBuilder builder = new StringBuilder();
                for(int i = 0; i < args.length; i++) {
                    builder.append(args[i]);
                    builder.append(" ");
                }
                //Make the "name" var Pt2
                String name = builder.toString();
                name = name.stripTrailing();
                //Chat API call
                HttpRequest request = HttpRequest.newBuilder()
                        .uri(URI.create("http://api.malcolmjh.com:8080/check_name?name=" + name))
                        .method("GET", HttpRequest.BodyPublishers.noBody())
                        .build();
                HttpResponse<String> response = null;
                try {
                    response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofString());
                } catch (IOException e) {
                    throw new RuntimeException(e);
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
                // Print the response
                p.sendMessage(ChatColor.DARK_BLUE + response.body());
            }
        }
        return true;
    }
}

does anyone know how to do a API request in java 8?

Any reason you're still stuck on Java 8? In any case, there are many ways to make API calls. Personally, I would try to avoid doing all the low level stuff by hand these days.

 

For example you could use OkHTTP, which works on Java 8 or newer. And if the API is HTTP based, then Retrofit is a good library to use on top of OkHTTP. It allows you to write a simple interface, containing a few annotated method. You can call these methods like other regular Java methods and under the hood they will make the appropriate HTTP API calls for you.
