本文主要向大家介绍机器人之人工智能初体验（二）：开发简单的图灵智能聊天工具了，通过具体的内容向大家展现，希望对大家学习机器人有所帮助。

前言：这里为了有更好的个性化设置，因此我选择了图灵机器人（//www.tuling123.com/）的接口，使用方法跟上一篇中使用百度的接口是差不多的。注：文末有打包好的小软件和完整源代码的下载链接一 API Key申请申请地址：//www.tuling123.com/中间的注册登录过程不说，最后把API Key值记录下来二核心功能开发这个小项目的目录结构：核心功能文件TuringRobot.java，代码很简单，一看就明白，代码如下：package action;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLEncoder;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class TuringRobot {
/**
  * 使用图灵机器人接口获取回答
  *
  * @param apikey API认证
  * @param info 想要请求的问题
  * @return 获取的回复
  * */
public static String getResponse(String apikey,String info){
  String httpUrl;
  try {
   httpUrl = "//www.tuling123.com/openapi/api?key=" + apikey + "&info=" + URLEncoder.encode(info,"UTF-8");
   URL url = new URL(httpUrl);
   HttpURLConnection connection = (HttpURLConnection) url.openConnection();
   connection.setRequestMethod("GET");
   connection.setReadTimeout(5000);
   connection.setConnectTimeout(5000);

   InputStream inputStream = connection.getInputStream();
   BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
   String line = "";
   String reg = "\"text\":\"(.*)?\"}";
   Pattern pattern = Pattern.compile(reg);
   Matcher matcher;
   while((line = reader.readLine()) != null){
    matcher = pattern.matcher(line);
    if(matcher.find()){
     connection.disconnect();
     return matcher.group(1);
    }
   }
   connection.disconnect();
  } catch (UnsupportedEncodingException e1) {
   e1.printStackTrace();
  } catch (MalformedURLException e) {
   e.printStackTrace();
  } catch (IOException e) {
   e.printStackTrace();
  }
  return "";
}

/**
  * 使用百度接口获取回答
  *
  * @param key 默认值：879a6cb3afb84dbf4fc84a1df2ab7319
  * @param ApiKey 在APIStore调用服务所需要的API密钥，申请地址：//apistore.baidu.com
  * @param info 想要请求的问题
  * @param userid 用户id 默认值：eb2edb736
  *
  * @return 获取的回复
  * */
public static String getResponse(String key,String ApiKey,String info,String userid){
  String httpUrl = "//apis.baidu.com/turing/turing/turing?";
  try {
   info = URLEncoder.encode(info,"UTF-8");
  } catch (UnsupportedEncodingException e1) {
   e1.printStackTrace();
  }
  String httpArg = "key=" + key + "&info=" + info + "&userid=" + userid;
  try {
   URL url = new URL(httpUrl + httpArg);
   HttpURLConnection connection = (HttpURLConnection) url.openConnection();
   connection.setRequestMethod("GET");
   connection.setRequestProperty("apikey", ApiKey);

   InputStream inputStream = connection.getInputStream();
   BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
   String line = "";
   String reg = "\"text\":\"(.*)?\",\"code\"";
   Pattern pattern = Pattern.compile(reg);
   Matcher matcher;
   while((line = reader.readLine()) != null){
    matcher = pattern.matcher(line);
    if(matcher.find()){
     connection.disconnect();
     return matcher.group(1);
    }
   }
   connection.disconnect();
  } catch (MalformedURLException e) {
   e.printStackTrace();
  } catch (IOException e) {
   e.printStackTrace();
  }
  return "";

}

}三前台界面开发在界面开发中有几个关键点需要注意：（1）使用了新的线程来执行数据获取过程，并且通过SwingUtilities.invokeLater()来通知EDT更新界面。具体技术可以参考我写的这篇文章：//www.zifangsky.cn/2015/12/java中事件分发线程（edt）与swingutilities-invokelater相关总结/（2）本来最开始是使用了JTextArea来显示聊天记录，后来发现不能对聊天双方的记录分别左对齐和右对齐，而且也不能对聊天记录中的文字颜色和字体进行个性化设置，因此后来将聊天界面的JTextArea改成了JTextPane。这是一个强大的控件，我这里仅仅只是进行了简单使用，看代码就明白了（3）API Key保存在配置文件config/config.txt中了界面代码如下：package view;
