如何将十六进制缓冲区转换为十六进制数组？

// 假设已经获取到了十六进制缓冲区
const hexBuffer = Buffer.from('48656c6c6f20576f726c64', 'hex');

// 将缓冲区转换为十六进制字符串
const hexString = hexBuffer.toString('hex');

// 将十六进制字符串拆分为两个字符一组，得到十六进制数组
const hexArray = [];
for (let i = 0; i < hexString.length; i += 2) {
  hexArray.push(hexString.substr(i, 2));
}

console.log(hexArray);

[ '48', '65', '6c', '6c', '6f', '20', '57', '6f', '72', '6c', '64' ]
