Pfsense捕获门户凭证生成，无需登录防火墙

Pfsense捕获门户凭证生成，无需登录防火墙,pfsense,Pfsense,我想知道是否有任何方法可用于生成可在Pfsense captive portal中兑换的凭单。基本上，我有一个防火墙，可以将互联网连接到客人的wifi路由器。我希望有某种形式的界面，让员工能够创建凭证并将其提供给客户，而无需登录wifi。我在网上找到了两条线索，但都不管用了。有什么建议吗？提前感谢。我刚刚完成了一个简单的php页面。它使用mysql数据库，它只有两个表，一个用于凭证，另一个用于IP地址，我想授予对该页面的访问权一旦用户选择凭证类型（分钟）并点击“生成”，则会在本地数据库中选择任

我想知道是否有任何方法可用于生成可在Pfsense captive portal中兑换的凭单。基本上，我有一个防火墙，可以将互联网连接到客人的wifi路由器。我希望有某种形式的界面，让员工能够创建凭证并将其提供给客户，而无需登录wifi。我在网上找到了两条线索，但都不管用了。有什么建议吗？提前感谢。

我刚刚完成了一个简单的php页面。它使用mysql数据库，它只有两个表，一个用于凭证，另一个用于IP地址，我想授予对该页面的访问权

一旦用户选择凭证类型（分钟）并点击“生成”，则会在本地数据库中选择任何有效凭证并将其标记为已使用

您必须在“validade”列中进行手动更新，才能为所有凭证设置值“1”[表示有效]。页面选择后，它将更新为“0”[表示已使用]

update vouchers set validade = 1;

对于允许访问页面的IP地址：

CREATE TABLE `usuarios` (
  `id_usuario` int(11) NOT NULL AUTO_INCREMENT,
  `ip_maquina` varchar(15) DEFAULT NULL,
  `departamento` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`id_usuario`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;

您必须在此表中手动插入，解析管理计算机的IP地址及其名称/位置/标签/您想用作人类可读ID的任何内容

insert into usuarios(ip_maquina, departamento) values ('10.91.198.12', 'Cyber Cafe');

注：字段名称为葡萄牙语

要将.csv文件从PfSense加载到本地数据库，请执行以下操作：

LOAD DATA LOCAL INFILE '/home/infra/Downloads/vouchers.csv' 
INTO TABLE vouchers
LINES TERMINATED BY '\n' (cod_voucher);
