1.http发送 post请求

1.1 JSONObject转换为String类型后进行发送

1.1.1头部请求添加：` conn.setRequestProperty(“Content-Type”, “application/json”);

1.1.2 发送操作主要部分

		OutputStreamWriter  out = null;
    	String json = obj.toJSONString();
        out = new OutputStreamWriter(conn.getOutputStream(), "utf-8");
            out.write(json);
            out.flush();

 /**
     * 向指定 URL 发送POST方法的请求
     *
     * @param url 发送请求的 URL
     * @param obj 请求参数，请求参数应该是JSONObject 的形式。
     * @return 所代表远程资源的响应结果
