微信公众号接入图灵机器人实现自动回复消息

1、创建图灵机器人

    进入图灵机器人网址：http://www.tuling123.com/

    登录/注册，进入机器人管理，然后点击创建机器人

然后我们选择或填写机器人的相关属性，这里我选择的是聊天社交，模拟真人聊天的机器人，应用终端由于是微信公众号接入，机器人设置里面，我们可以拿到接口api相关的信息。直接上图：

2、后端代码开始接入

常量类

public final class Constants {

    /**
     * GET或POST必须大写，不可更改
     */
    public static final String GET = "GET";
    public static final String POST = "POST";

   /* 微信请求消息类型（由微信方规定，不可更改） */
    /**
     * 文本
     */
    public static final String REQ_TEXT_TYPE = "text";
    /**
     * 事件
     */
    public static final String REQ_EVENT_TYPE = "event";
    /**
     * 订阅
     */
    public static final String REQ_SUBSCRIBE_TYPE = "subscribe";
    /**
     * 取消订阅
     */
    public static final String REQ_UNSUBSCRIBE_TYPE = "unsubscribe";

   /* 微信返回消息类型（由微信方规定，不可更改） */
    /**
     * 文本

    public static final String RESP_TEXT_TYPE = "text";
    /**

    public static final String RESP_NEWS_TYPE = "news";

   /* 图灵机器人返回数据类型状态码(官方固定) */
    /**
     * 文本
     */
    public static final Integer TEXT_CODE = 100000;
    /**
     * 列车

    public static final Integer TRAIN_CODE = 305000;
    /**
     * 航班

    public static final Integer FLIGHT_CODE = 306000;
    /**
     * 链接类

    public static final Integer LINK_CODE = 200000;
    /**

    public static final Integer NEWS_CODE = 302000;
    /**

    public static final Integer MENU_CODE = 308000;

    public static final Integer LENGTH_WRONG_CODE = 40001;
    /**

    public static final Integer EMPTY_CONTENT_CODE = 40002;
    /**

    public static final Integer KEY_WRONG_CODE = 40003;
    /**

    public static final Integer NUMBER_DONE_CODE = 40004;
    /**

    public static final Integer NOT_SUPPORT_CODE = 40005;
    /**

    public static final Integer UPGRADE_CODE = 40006;
    /**
     * 服务器数据格式异常
     */
    public static final Integer DATA_EXCEPTION_CODE = 40007;

    /**
     * 获取access_token的接口地址
     */
    public final static String ACCESS_TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=&secret=";

    /**
     * 图灵机器人接口地址
     */
    public final static String TURING_API_URL = "http://www.tuling123.com/openapi/api";

    private Constants() {
    }
}

服务层处理文本消息

@Service
public class TextMessageHandle {

    /**
     * 处理文本消息
     *
     * @param customName  用户
     * @param severName   微信服务器
     * @param textContent 文本内容
     * @return
     * @throws Exception
     */
    public String processMessage(String customName, String severName, String textContent) throws Exception {
        String fromUserName = customName;
        String toUserName = severName;
        String content = textContent;
        String info = URLEncoder.encode(content, "utf-8");
        String requestUrl = Constants.TURING_API_URL + "?key=" + AppConstants.API_KEY
                + "&info=" + info + "&userid=" + fromUserName;
        String result = HttpUtil.get(requestUrl);
        Object obj = MessageUtil.processTuRingResult(result, toUserName,
                fromUserName);
        return MessageUtil.ObjectToXml(obj);
    }
}

文本消息类

@XStreamAlias("xml")
public class TextMessage extends BaseMessage{

    @XStreamAlias("Content")
    @XStreamCDATA
    private String Content;

    public TextMessage() {

    }

    public TextMessage(String fromUserName, String toUserName, String content) {
        super(fromUserName, toUserName);
        super.setMsgType(Constants.RESP_TEXT_TYPE);
        this.Content = content;
    }

    public String getContent() {
        return Content;
    }

    public void setContent(String content) {
        Content = content;
    }
}

基础消息

public class BaseMessage implements Serializable {
    @XStreamAlias("ToUserName")
    @XStreamCDATA
    private String ToUserName;

    @XStreamAlias("FromUserName")
    @XStreamCDATA
    private String FromUserName;

    @XStreamAlias("CreateTime")
    private Long CreateTime;

    @XStreamAlias("MsgType")
    @XStreamCDATA
    private String MsgType;

    public BaseMessage() {
        super();
    }

    public BaseMessage(String fromUserName, String toUserName) {
        super();
        FromUserName = fromUserName;
        ToUserName = toUserName;
        CreateTime = System.currentTimeMillis();
    }

    public String getToUserName() {
        return ToUserName;
    }

    public void setToUserName(String toUserName) {
        ToUserName = toUserName;
    }

    public String getFromUserName() {
        return FromUserName;
    }

    public void setFromUserName(String fromUserName) {
        FromUserName = fromUserName;
    }

    public Long getCreateTime() {
        return CreateTime;
    }

    public void setCreateTime(Long createTime) {
        CreateTime = createTime;
    }

    public String getMsgType() {
        return MsgType;
    }

    public void setMsgType(String msgType) {
        MsgType = msgType;
    }
}

应用常量

public final class AppConstants {

    /**
     * 应用id
     */
    public static String APP_ID = "";
    /**
     * 应用秘钥
     */
    public static String APP_SECRET = "";
    /**
     * 令牌
     */
    public static String TOKEN = "";
    /**
     * 图灵机器人应用key
     */
    public static String API_KEY = "";
}

最后服务层处理来自文本消息

else if (MsgType.TEXT.getValue().equals(msgType)) {
    //点击菜单
    //回复微信服务器成功
    try {
        String result;
        result = textMessageHandle.processMessage(custermname, servername, content);
        writeText(result, response);
        }
    } catch (Exception e) {
        logger.error("接收来至微信服务器的消息出现错误", e);
        writeText(MessageUtil.ObjectToXml(new TextMessage(custermname,
                servername, "我竟无言以对！")), response);
        e.printStackTrace();
    }

private void writeText(String content, HttpServletResponse response) {
    Writer writer = null;
    try {
        response.setContentType("text/html");
        response.setCharacterEncoding("UTF-8");
        writer = response.getWriter();
        writer.write(content);
        writer.flush();
    } catch (IOException e) {
        logger.error("响应客户端文本内容出现异常", e);
    } finally {
        IOUtils.close(writer);
    }
}

结果：
