微信發送模板消息

 

1. 在微信公眾號上添加模板

在模板庫添加自己需要的模板，得到模板ID

我用的模板

 

 2. 獲取access_token

private static final String URL_ACCESS_TOKEN = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s";
    public String getAccessToken() throws Exception {
        String appid = wxConfig.getAppid();//微信公眾號申請是獲得
        String secret = wxConfig.getSecret();//微信公眾號申請是獲得
        String url = String.format(URL_ACCESS_TOKEN, appid, secret);
        String body = HttpHelper.doGet(url);//這里使用的是OkHttp輕量級框架
        JSONObject response = JSONObject.fromObject(body);
　　　　　String token="";
        if(!response.containsKey("errcode")){
           token=response.getString("access_token");return token;
        }else{
            throw new Exception(body);
        }
    }

3.推送模板消息

模板消息實體類

 發送消息

private static final String SEND_TEMPLATE_MESSAGE="https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=%s";
public void testMessage(){
        WxTMessage message=new WxTMessage();
        
        message.setTemplate_id("EzJ1LYo-PeBwDpBB8gG4NeWTdv2gmqExY304UTWAGco");
        message.setTouser("xxxxxxxxxxxx");//接受者的openID
        message.setUrl("https://www.baidu.com/");
        
        message.addParams("first", "測試：用來測試的呀", "");
        message.addParams("content", "沒了", "#4895de");

        message.addParams("remark", "請隨時關注處理！","");

        String token=getAccessToken();
　　　　　　
        String url = String.format(SEND_TEMPLATE_MESSAGE, token);
        String body = HttpHelper.doPost(url, message.toJSONString());//使用OkHttp框架
        JSONObject response = JSONObject.fromObject(body);
        if(null!=response){
            if("0".equals(response.getString("errcode"))){
                System.out.println("發送模板消息成功");
                return true;
            }else{
                throw new Exception("發送模板消息失敗: "+response.getString("errcode"));
            }
        }else{
            throw new Exception("response為空");
        }
    }

 ps:模板消息中可以拼接"\n"來控制行

 

最近一直在做微信相關的東西，為防止以后自己忘記，先記下一些基礎的功能，今天發的是關於微信發送模板消息，哎，字數不夠，這句話是用來湊字數
