json提取数据 https://blog.csdn.net/qq_37581708/article/details/72367803

通过post方法请求

		return result;
	}

	public static JSONObject transJosn(String text) { // 构造JSON请求参数

		jsonObject.put("reqType", "0");

		JSONObject perception = new JSONObject();

		jsonObject.put("userInfo", userInfo);

	}

}

调用（我这个是在微信公众号中调用）

	JSONObject jsonObject = HttpRobot.transJosn(content); // content是文本消息
	String js = HttpRobot.postJson(ROBOT_URL, jsonObject.toString());
