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（http://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：http://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 = "http://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：http://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 = "http://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：http://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;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.Toolkit;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;

import java.util.regex.Pattern;
