微信消息订阅报{"errcode":47001,"errmsg":"data format error hint: [VlcJia0987ge21]"} java代码

微信消息订阅遇到的一些坑

首先看微信官方提供的说明文档：https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/subscribe-message.html
详细内容请看文档说明

简要说明如下

 

 

服务器代码：

   /**
     * 生成模板消息
     * @param openid
     * @param msg
     */
    public static void templateMsg(String openid,String msg) {

        String url = "https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=" + CommonUtil.getAccessToken();

        try {
            JSONObject map = new JSONObject();
            map.put("touser", openid);
            map.put("template_id", "G5Z3j8fLSBReDmnOHemFoyCA_6qHGWojdOMsz0UXEQ4");
　　　　　　　//developer 开发板；trial 测试版;formal为正式版；默认正式版， 上线要改成formal
            map.put("miniprogram_state","trial");
            JSONObject data = new JSONObject();
            String time = DateFormatUtils.format(new Date(), "yyyy年MM月dd日 HH:mm");
            data.put("thing3",new ValueVo(msg));
            data.put("time4", new ValueVo(time));
            map.put("data", data);

            String jsonStr = httpsRequest(url, "POST", map.toJSONString());
            JSONObject json = JSONObject.parseObject(jsonStr);
            System.err.println("打印"+json);

        } catch (Exception e) {
            e.printStackTrace();
            System.err.println("消息订阅异常！");
        }
    }


    public static String httpsRequest(String requestUrl, String requestMethod, String output) throws Exception {
        URL url = new URL(null, requestUrl, new Handler());
        HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setUseCaches(false);
        connection.setRequestMethod(requestMethod);
        if (null != output) {
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(output.getBytes("UTF-8"));
            outputStream.close();
        }
        // 从输入流读取返回内容
        InputStream inputStream = connection.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
        String str = null;
        StringBuffer buffer = new StringBuffer();
        while ((str = bufferedReader.readLine()) != null) {
            buffer.append(str);
        }
        bufferedReader.close();
        inputStreamReader.close();
        inputStream.close();
        inputStream = null;
        connection.disconnect();
        return buffer.toString();
    }

public class ValueVo {

    private String value;

    public ValueVo(String value) {
        this.value = value;
    }
}

打印{"errcode":0,"errmsg":"ok","msgid":1838082200404099077}
