微信公众号开发<关键字匹配回复随机内容>

最后我实现的功能是用户回复公众号电影名称，公众号自动回复网盘链接，回复“美女”“搞笑”等关键词自动回复随机一张类别图片
1.公众号配置好开发地址

/**     * 接入微信     *     * @param request  request     * @param response response     * @throws IOException IOException     */    @RequestMapping(value = "/wechatconnect")    @ResponseBody    public void wechatconnect(HttpServletRequest request,                              HttpServletResponse response) throws IOException {        // 将请求、响应的编码均设置为UTF-8（防止中文乱码）        request.setCharacterEncoding("UTF-8");        response.setCharacterEncoding("UTF-8");        boolean isGet = request.getMethod().toLowerCase().equals("get");        PrintWriter out = response.getWriter();        try {            if (isGet) {                String signature = request.getParameter("signature");// 微信加密签名                String timestamp = request.getParameter("timestamp");// 时间戳                String nonce = request.getParameter("nonce");// 随机数                String echostr = request.getParameter("echostr");//随机字符串                // 通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败                if (SignUtil.checkSignature(signature, timestamp, nonce)) {                    logger.info("Connect the weixin server is successful.");                    response.getWriter().write(echostr);                } else {                    logger.error("Failed to verify the signature!");                }            } else {                String respMessage = "异常消息！";                try {                    respMessage = weixinPost(request);                    out.write(respMessage);                    logger.info("The request completed successfully");                    logger.info("to weixin server " + respMessage);                } catch (Exception e) {                    e.printStackTrace();                    logger.error("Failed to convert the message from weixin!");                }            }        } catch (Exception e) {            logger.error("Connect the weixin server is error.");        } finally {            out.close();        }    }

然后做关键词匹配的功能，用户给公众号发送的消息都会通过腾讯request请求到你配置的开发者地址上，然后就是实现自己的逻辑，包括自动回复相关内容;

    public String weixinPost(HttpServletRequest request) {        String respMessage = null;        try {            // xml请求解析            Map<String, String> requestMap = MessageUtil.xmlToMap(request);            // 发送方帐号（open_id）            String fromUserName = requestMap.get("FromUserName");            // 公众帐号            String toUserName = requestMap.get("ToUserName");            // 消息类型            String msgType = requestMap.get("MsgType");            // 消息内容            String content = requestMap.get("Content");            logger.info("---------------FromUserName is:" + fromUserName + ", ToUserName is:" + toUserName + ", MsgType is:" + msgType + content);            // 文本消息            if (msgType.equals(MessageUtil.REQ_MESSAGE_TYPE_TEXT)) {                //这里根据关键字执行相应的逻辑，只有你想不到的，没有做不到的                PicturePool pp = wechatResourceService.selectPictureWechat(content);                MoviePool mp = wechatResourceService.selectMovieWechat(content);                if (pp != null) {                    //自动回复图片                    ImgMessage imgMessage = new ImgMessage();                    WechatPicture wechatPicture = wechatResourceService.getPicture(pp.getId());                    Image image = new Image();                    image.setMediaId(wechatPicture.getMedia_id());                    imgMessage.setImage(image);                    imgMessage.setToUserName(fromUserName);                    imgMessage.setFromUserName(toUserName);                    imgMessage.setCreateTime(new Date().getTime());                    imgMessage.setMsgType(MessageUtil.RESP_MESSAGE_TYPE_IMAGE);                    respMessage = MessageUtil.imgMessageToXml(imgMessage);                } else if (mp != null) {                    //自动回复                    TextMessage text = new TextMessage();                    text.setContent(mp.getAddress());                    text.setToUserName(fromUserName);                    text.setFromUserName(toUserName);                    text.setCreateTime(new Date().getTime());                    text.setMsgType(msgType);                    respMessage = MessageUtil.textMessageToXml(text);                } else {                    TextMessage text = new TextMessage();                    text.setContent("亲，关键词匹配不上呢，请检查一下是否有同音字吧~\n" +                            "回复“美女”“男神”“海报”“搞笑”等命令，可以获得相对应的精美图片。\n" +                            "回复“电影”或者您想看的电影名称，即可得到在线观看的网址或云盘资源的链接。\n");

最终实现效果如图所示：
