Node.js net.BlockList.check(address[, type])用法及代碼示例

blockList.check(address[, type])

參數

• address <string> | <net.SocketAddress> 要檢查的 IP 地址
• type <string> 'ipv4' 或 'ipv6' 。 默認： 'ipv4' 。
• 返回： <boolean>

如果給定的 IP 地址與添加到 BlockList 的任何規則匹配，則返回 true。

const blockList = new net.BlockList();
blockList.addAddress('123.123.123.123');
blockList.addRange('10.0.0.1', '10.0.0.10');
blockList.addSubnet('8592:757c:efae:4e45::', 64, 'ipv6');

console.log(blockList.check('123.123.123.123'));  // Prints: true
console.log(blockList.check('10.0.0.3'));  // Prints: true
console.log(blockList.check('222.111.111.222'));  // Prints: false

// IPv6 notation for IPv4 addresses works:
console.log(blockList.check('::ffff:7b7b:7b7b', 'ipv6')); // Prints: true
console.log(blockList.check('::ffff:123.123.123.123', 'ipv6')); // Prints: true
