Java调用腾讯AI智能聊天服务的方法

本文章只做个人记录使用，有需要可以参考，不明白下方留言

直接上代码，首先，传过来你要发送的消息

 

TencentAIAnswer 实体类

import java.io.Serializable;

/**
 * 收到的微信消息

 * @date 创建时间：2017年7月3日 下午10:28:06
 * @version 1.0

 */
public class TencentAIAnswer implements Serializable {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String session;
	private String answer;

	public String getSession() {
		return session;
	}

	public void setSession(String session) {
		this.session = session;
	}

	public String getAnswer() {
		return answer;
	}

	public void setAnswer(String answer) {
		this.answer = answer;
	}

}

		sb.append(strNum);

	/**

}

public static String getAiAnswer(String msg) {
		String result = null;
		Map tempParamS = new HashMap<>();
		Map signMap;
		try {
			tempParamS.put("app_id", app_id);
			tempParamS.put("time_stamp", new Date().getTime() / 1000 + "");
			tempParamS.put("nonce_str", RandomUtils.generateString(16));
			tempParamS.put("session", RandomUtils.getNotSimple(6) + "");
			tempParamS.put("question", msg);

			signMap = Sign.getSignature(tempParamS, app_key);
			String rel = HttpsPostUtil.doPost(url, signMap, "UTF-8");
			if (StringUtils.isNotBlank(rel)) {
				JSONObject obj = JSON.parseObject(rel);
				if (0 == obj.getInteger("ret")) {
					TencentAIAnswer objRet = obj.parseObject(obj.getString("data"), TencentAIAnswer.class);
					result = objRet.getAnswer();
				}
				if (obj.getInteger("ret") < 0) {
					result = "网络异常~";
				}
				if (obj.getInteger("ret") > 0) {
					result = "我脑子被麻花藤玩坏了哦，快找我爸爸韩梅梅帮我看看吧~";
				}
			} else {
				result = "我病了，现在不能回答你任何问题哦~";
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return result;
	}

获得签名的方法实现

public static Map getSignature(Map params, String CONFIG) throws IOException {
		Map sortedParams = new TreeMap<>(params);
		Set> entrys = sortedParams.entrySet();
		StringBuilder baseString = new StringBuilder();
		for (Map.Entry param : entrys) {
			if (param.getValue() != null && !"".equals(param.getKey().trim()) && !"sign".equals(param.getKey().trim())
					&& !"".equals(param.getValue())) {
				baseString.append(param.getKey().trim()).append("=")
						.append(URLEncoder.encode(param.getValue().toString(), "UTF-8")).append("&");
			}
		}
		if (baseString.length() > 0) {
			baseString.deleteCharAt(baseString.length() - 1).append("&app_key=").append(CONFIG);
		}
		try {
			String sign = MD5Utils.getMD5String(baseString.toString());
			sortedParams.put("sign", sign);
		} catch (Exception ex) {
			throw new IOException(ex);
		}
		return sortedParams;
	}

下面是POST请求的实现，要注意这个地方是https的请求，所以我们要先封装SSL类以便略过证书的检查

public class SSLClient extends DefaultHttpClient {
	// 用于进行Https请求的HttpClient
	public SSLClient() throws Exception {
		super();
		SSLContext ctx = SSLContext.getInstance("TLS");
		X509TrustManager tm = new X509TrustManager() {
			@Override
			public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
			}

			@Override
			public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
			}

			@Override
			public X509Certificate[] getAcceptedIssuers() {
				return null;
			}
		};
		ctx.init(null, new TrustManager[] { tm }, null);
		SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
		ClientConnectionManager ccm = this.getConnectionManager();
		SchemeRegistry sr = ccm.getSchemeRegistry();
		sr.register(new Scheme("https", 443, ssf));
	}

下面是POST请求实现

public static String doPost(String url, Map map, String charset) {
		HttpClient httpClient = null;
		HttpPost httpPost = null;
		String result = null;
		try {
			httpClient = new SSLClient();
			httpPost = new HttpPost(url);
			// 设置参数
			List list = new ArrayList();
			Iterator iterator = map.entrySet().iterator();
			while (iterator.hasNext()) {
				Entry elem = (Entry) iterator.next();
				list.add(new BasicNameValuePair(elem.getKey(), elem.getValue()));
			}
			if (list.size() > 0) {
				UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list, charset);
				httpPost.setEntity(entity);
			}
			HttpResponse response = httpClient.execute(httpPost);
			if (response != null) {
				HttpEntity resEntity = response.getEntity();
				if (resEntity != null) {
					result = EntityUtils.toString(resEntity, charset);
				}
			}
		} catch (Exception ex) {
			ex.printStackTrace();
		}
		return result;
	}

这样就完成了，写的简单点，不是因为别的，就是因为我太懒
