如何在JavaScript中将十六进制字符串转换为Uint8Array？

function hexToUint8Array(hexString) {
  // 去除字符串中的空格
  hexString = hexString.replace(/\s/g, '');

  // 将十六进制字符串转换为匹配的数组
  const hexArray = hexString.match(/.{1,2}/g);

  // 将每个十六进制数值转换为对应的十进制数值
  const uint8Array = Array.from(hexArray, hex => parseInt(hex, 16));

  return new Uint8Array(uint8Array);
}

const hexString = "48656C6C6F20576F726C64"; // 十六进制字符串

const uint8Array = hexToUint8Array(hexString);
console.log(uint8Array);

function hexToUint8Array(hexString) {
  // 去除字符串中的空格
  hexString = hexString.replace(/\s/g, '');

  // 将十六进制字符串转换为匹配的数组
  const hexArray = hexString.match(/.{1,2}/g);

  return Uint8Array.from(hexArray, hex => parseInt(hex, 16));
}

const hexString = "48656C6C6F20576F726C64"; // 十六进制字符串

const uint8Array = hexToUint8Array(hexString);
console.log(uint8Array);
