微信发送模板消息

 

1. 在微信公众号上添加模板

在模板库添加自己需要的模板，得到模板ID

我用的模板

 

 2. 获取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();//微信公众号申请是获得
        String secret = wxConfig.getSecret();//微信公众号申请是获得
        String url = String.format(URL_ACCESS_TOKEN, appid, secret);
        String body = HttpHelper.doGet(url);//这里使用的是OkHttp轻量级框架
        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

模板消息实体类

    }
    
    /**

        return JSONObject.fromObject(this, config).toString();

    public String getTouser() {
        return touser;
    }

        this.touser = touser;
    }

 发送消息

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", "测试：用来测试的呀", "");
        message.addParams("content", "没了", "#4895de");
        message.addParams("occurtime", "2018-04-27 11:14:52", "#666666");
        message.addParams("remark", "请随时关注处理！","");

        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("发送模板消息成功");
                return true;
            }else{
                throw new Exception("发送模板消息失败: "+response.getString("errcode"));
            }
        }else{
            throw new Exception("response为空");
        }
    }

 ps:模板消息中可以拼接"\n"来控制行

 

最近一直在做微信相关的东西，为防止以后自己忘记，先记下一些基础的功能，今天发的是关于微信发送模板消息，哎，字数不够，这句话是用来凑字数
