3. 订阅消息

String tk=WeixinUtil.getAccessToken().getToken();
    String url="https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token="+tk;
    Map<String, Object> map = new HashMap<String, Object>();
    map.put("template_id", template_id);
    map.put("touser", openid);
//        Map<String, Object> data  = new HashMap<String, Object>();
          Map<String, Object> m1,m2 ,m3;
          m1 = new HashMap<String, Object>();
          m1.put("value", "天气提醒，你哈哈哦");
          m2  = new HashMap<String, Object>();
          m2.put("value", "今天天气很棒哦");
          m3  = new HashMap<String, Object>();
          m3.put("value", "快来看看吧");
            
        data.put("thing1", m1);
        data.put("thing2", m2);
        data.put("thing3", m3);
    map.put("data",data);
    map.put("miniprogram_state",miniprogram_state);
    map.put("lang", "zh_CN");
    map.put("page", page);
    
    String r=HttpClient.doPost(url,JSON.toJSONString(map));

4. 后台推送

String tk=WeixinUtil.getAccessToken().getToken();
    String url="https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token="+tk;
    Map<String, Object> map = new HashMap<String, Object>();
    map.put("template_id", template_id);
    map.put("touser", openid);
//        Map<String, Object> data  = new HashMap<String, Object>();
          Map<String, Object> m1,m2 ,m3;
          m1 = new HashMap<String, Object>();
          m1.put("value", "天气提醒，你哈哈哦");
          m2  = new HashMap<String, Object>();
          m2.put("value", "今天天气很棒哦");
          m3  = new HashMap<String, Object>();
          m3.put("value", "快来看看吧");
            
        data.put("thing1", m1);
        data.put("thing2", m2);
        data.put("thing3", m3);
    map.put("data",data);
    map.put("miniprogram_state",miniprogram_state);
    map.put("lang", "zh_CN");
    map.put("page", page);
    
    String r=HttpClient.doPost(url,JSON.toJSONString(map));
