微信公众平台——模板消息接口

关于接口文档，请注意：

1、模板消息调用时主要需要模板ID和模板中各参数的赋值内容；
2、模板中参数内容必须以".DATA"结尾，否则视为保留字；
3、模板保留符号"{{ }}"。

1.service

/**
* 微信自动消息推送
* @author Administrator

*/
@Service
public class AutomaticMessagePushServiceImpl implements AutomaticMessageServicePush {

@Autowired
private MyCache cache;

@Override
public String AutomaticMessagePush(JSONObject JsonCustom,String first,String remark,String openId,String templateId,String customUrl,Integer identification) {

JSONObject Json = new JSONObject();

//头部
Jsonfirst.put("value", first);
Jsonfirst.put("color", "#000000");
//尾部

//自定义内容增加头和尾

//微信openId
Json.put("touser", openId);
//模板id
Json.put("template_id", templateId);
//详情跳转地址
Json.put("url", customUrl);
//json数据
Json.put("data", JsonCustom);

//根据标识发送对应公众号
String appid;
String appSecret;
String keyName ="";
if(identification==Constants.TALENT_IDENTIFICATION){
keyName = "wechatAccessToken";
appid = ConfigHelper.getInstance("config").getValue("DaRenAppID");

}

}
}catch(Exception e){
e.printStackTrace();
}finally {
if (br != null) {
try {

} catch (IOException e) {
// do nothing
}
}
}

}

2.controller调用
/**
* 绑定消息推送公共方法
* @param openId
*/
private void bindingPush(String openId) {
//发送自动消息推送
com.alibaba.fastjson.JSONObject Json = new com.alibaba.fastjson.JSONObject();
com.alibaba.fastjson.JSONObject name1 = new com.alibaba.fastjson.JSONObject();
com.alibaba.fastjson.JSONObject name2 = new com.alibaba.fastjson.JSONObject();
com.alibaba.fastjson.JSONObject time = new com.alibaba.fastjson.JSONObject();

name1.put("value", "通金达人");
name1.put("color", "#000000");

name2.put("value", "微信");
name2.put("color", "#000000");
//绑定时间
time.put("value", DateUtil.dateToString1(new Date()));
time.put("color", "#000000");

Json.put("name1", name1);
Json.put("name2", name2);
Json.put("time", time);

//消息头部
String first = "用户您好，恭喜您账户绑定成功！";
//消息尾部
String remark = "您可以使用下方微信菜单进行更多功能体验，如需解除绑定请回复'qxbd'";
//详情跳转页面
String customUrl = ConfigHelper.getInstance("config").getValue("DaRenPushUrl");
//根据json内容微信自动消息推送
servicePush.AutomaticMessagePush(Json,first,remark,openId,Constants.TALENT_BINDING_SUCCESS,customUrl,Constants.TALENT_IDENTIFICATION);
}
