微信公众号开发-模板推送封装参数

不得不说微信的开发文档的恶心之处

• 微信推送模板

{{first.DATA}}
审核状态：{{keyword1.DATA}}
操作时间：{{keyword2.DATA}}
{{remark.DATA}}

• 我们数据库存储的格式

{
"touser":"${touser}",
"data":${data},
"template_id":"${template_id}",
"miniprogram":{"pagepath":"${pagepath}","appid":"${appid}"}
}

• 参数替换

 public List<String> wxTemplateConversion(WxTemplateVo wxTemplateVo, WxPushMsg wxPushMsg){
        List<String> wxPushPostMsg = new ArrayList<>();
        if(wxPushMsg != null && ValidateHelper.isNotEmptyCollection(wxPushMsg.getOpenidList())){
            for(String openid:wxPushMsg.getOpenidList()){
                //替换模板参数
                String postStr = wxTemplateVo.getContent();
                //模板ID
                postStr = postStr.replace("${template_id}", wxTemplateVo.getTemplateId());
                //微信小程序appid
                postStr = postStr.replace("${appid}", wxPushMsg.getAppid());
                //微信公众号用户openid
                postStr = postStr.replace("${touser}", openid);
                //微信小程序内部地址
                postStr = postStr.replace("${pagepath}", wxPushMsg.getPagepath());
                //推送参数
                postStr = postStr.replace("${data}", JSONObject.toJSONString(wxPushMsg.getData()));
                wxPushPostMsg.add(postStr);
            }
        }
        return wxPushPostMsg;
    }

• 主要的是data的数据封装,使用可变参进行封装,尽量避免繁琐的first,remark的写法

 public static TreeMap<String,WxTemplateData> buildWxTemplateMsgData(WxTemplateData first, WxTemplateData remark, WxTemplateData...templateList){
        TreeMap<String, WxTemplateData> dataTreeMap = new TreeMap<>();
        dataTreeMap.put("first", first);
        for(int index = 0;index < templateList.length ;index++){
            String key = "keyword" + (index+ 1);
            dataTreeMap.put(key, templateList[index]);
        }
        dataTreeMap.put("remark", remark);
        return dataTreeMap;
    }

• 调用

TreeMap<String, WxTemplateData> dataTreeMap = WxPushUtil.buildWxTemplateMsgData(new WxTemplateData("感谢您进行实名认证!", ""),
                    new WxTemplateData("**********************！", "#FF0000"),
                    new WxTemplateData("认证成功", ""),
                    new WxTemplateData(TimeUtil.getNowTime(), "")
            );
