关于这个例子的完整介绍，请参考公众号 “汪子熙”的两篇文章：SAP C/4HANA与人工智能和增强现实(AR)技术结合的又一个创新案例和使用Recast.AI创建具有人工智能的聊天机器人：本文介绍如何用Java代码同recast.AI网站上创建好的模型交互。我创建了一个名为get-product-infomation的机器学习模型，用"Add an expression"下面的这么多句子去喂这个模型：一会测试时，我会用这个句子进行测试 " I am looking for some materials", 所以先记下来。如果任意输入一句话，recast.AI识别出来意图为get-product-infomation, 我希望AI自动返回一些句子，这些句子定义在recast.AI模型的Actions标签页下面：比如这个Actions模型的意思是，从Sure, what type of product are you going to produce?和Cool, what products do you want to produce?里随机挑选一句返回。下图右半部份是recast.AI的测试控制台。下面是用Java代码方式消费这个人工智能模型的例子：public class RecastAIService {private final static String RECAST_AI_URL = “https://api.recast.ai/build/v1/dialog";private final static String DEVELOPER_TOKEN = “Token feb6b413a1a8cf8efdd53f48ba1d4”;public Answer dialog(final String content, final String conversationId) throws ClientProtocolException, IOException{CloseableHttpClient httpClient = HttpClients.createDefault();HttpPost postRequest = new HttpPost(RECAST_AI_URL);postRequest.addHeader(“Authorization”, DEVELOPER_TOKEN);postRequest.addHeader(“Content-Type”, “application/json”);String body = “{“message”: {“content”:”"+ content+ “”,“type”:“text”}, “conversation_id”: “"+ conversationId+””}";HttpEntity entity = new StringEntity(body);postRequest.setEntity(entity);HttpResponse response = httpClient.execute(postRequest);if(response.getStatusLine().getStatusCode() == 200){String result = EntityUtils.toString(response.getEntity());JSONObject resultJsonObj = JSON.parseObject(result);JSONObject results = (JSONObject) resultJsonObj.get(“results”);JSONArray messages = results.getJSONArray(“messages”);JSONObject nlp = (JSONObject) results.get(“nlp”);JSONArray intents = nlp.getJSONArray(“intents”);Answer answer = new Answer();if (null != messages && messages.size() > 0){JSONObject messageJson = messages.getJSONObject(0);answer.setContent(messageJson.getString(“content”));}if (null != intents && intents.size() > 0){JSONObject intentJson = intents.getJSONObject(0);answer.setIntent(intentJson.getString(“slug”));}return answer;}logger.debug(“Failed to access recastai. The response code is” + response.getStatusLine().getStatusCode());return null;}测试代码：传入I am looking for some materials，recast.AI解析出这个句子的意图有99%的可能性是get-product-information：Java代码返回的句子也确实是recast.AI模型里维护的回复之一：要获取更多Jerry的原创文章，请关注公众号"汪子熙":
