调用示例：

java 复制代码

    Map<String, Object> personInfoMap = new HashMap<>();
    personInfoMap.put("xxx", ""); 
    String params = JSONObject.toJSONString(personInfoMap);
	//调用接口发送数据
    String jsonStr = BeanUtiles.doPost(urlStr, params, clientId, authorization);
	//处理返回信息
    JSONObject jsonObject = JSONObject.parseObject(jsonStr);
    Integer code = jsonObject.getInteger("code");
    String msg = jsonObject.getString("msg");
    if (code == 200) {
       //调用成功
       String returnData= jsonObject.getString("data");
    } else {
       //调用失败
    }
