百度UNIT 机器人多轮对话技能创建以及API调用

基于百度UNIT2.0 版本，实现简单的多轮人机对话功能

创建机器人必备条件

  1. 确定有哪些技能
    例如：查询天气、订票、讲故事等，以畅越冰激凌套餐营销话术为例
    创建技能
  2. 确定技能包含的意图
    分析是任务型、闲聊型还是问答型。
    任务型： 将用户意图的关键词参数化成词槽，完成任务。例如订票、退票、办理业务等
    问答型：有固定答案的对话，回答比较明确。例如业务咨询，套餐查询
    闲聊型： 没有明确的意图或者任务只是随意聊天
    分析营销话术属于任务型，以推销套餐为任务的意图。
    流程图：
    流程
  3. 确定意图包含的词槽
    词槽：类似参数
  4. 为词槽添加词典
    注意如果词槽之间词典有重复的词语，会出现意图无法识别问题
  5. 为意图创建规则
    例如：对话中必须出现词槽中的词才会转到意图；一个意图可以匹配多个规则
  6. 创建对话模板
    不创建对话模板或者对话集，意图无法生效
  7. 训练模型
    通过技能训练将定义好的意图训练成模型，通过测试可以优化词槽或者修改规则优化模型

调用API

调用技能前提需要创建应用，获取API key 和Secret Key；使用两个key值获取调用api的token。

  1. 必备条件
    • token, 获取token需要API key 和Secret Key
    • 调用Api地址
    • 技能Id
  2. 调用实例
    参考代码地址
    部分代码。参考上述代码，实现多轮对话调用：
    获取token
/**
 * 获取token类
 */
public class AuthService {

    /**
     * 获取权限token
     * @return 返回示例：
     * {
     * "access_token": "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567",
     * "expires_in": 2592000
     * }
     */
    public static String getAuth() {
        // 官网获取的 API Key 更新为你注册的
        String clientId = "yRPuMmY6vbYVra0w8GhozQBF";
        // 官网获取的 Secret Key 更新为你注册的
        String clientSecret = "SNNVQ8ZqIob4XAQTEsVMkZ0uXKE9Amys";
        return getAuth(clientId, clientSecret);
    }

    /**
     * 获取API访问token
     * 该token有一定的有效期，需要自行管理，当失效时需重新获取.
     * @param ak - 百度云官网获取的 API Key
     * @param sk - 百度云官网获取的 Securet Key
     * @return assess_token 示例：

     */
    public static String getAuth(String ak, String sk) {
        // 获取token地址
        String authHost = "https://aip.baidubce.com/oauth/2.0/token?";
        String getAccessTokenUrl = authHost
                // 1. grant_type为固定参数
                + "grant_type=client_credentials"
                // 2. 官网获取的 API Key
                + "&client_id=" + ak
                // 3. 官网获取的 Secret Key
                + "&client_secret=" + sk;
        try {
            URL realUrl = new URL(getAccessTokenUrl);
            // 打开和URL之间的连接
            HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection();
            connection.setRequestMethod("GET");
            connection.connect();
            // 获取所有响应头字段
            Map<String, List<String>> map = connection.getHeaderFields();
            // 遍历所有的响应头字段
//            for (String key : map.keySet()) {
//                System.err.println(key + "--->" + map.get(key));
//            }
            // 定义 BufferedReader输入流来读取URL的响应
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String result = "";
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
            /**
             * 返回结果示例
             */
//            System.err.println("result:" + result);
            JSONObject jsonObject = new JSONObject(result);
            String access_token = jsonObject.getString("access_token");
            return access_token;
        } catch (Exception e) {
            System.err.printf("获取token失败！");
            e.printStackTrace(System.err);
        }
        return null;
    }
}

  1. 注意事项
    如果需要调用多轮对话，需要将每次获取到的结果中的bot_session 当做参数调用下一轮对话。
