如何将数字字节拆分成一个Uint8Array

function splitToUint8Array(number) {
  // 将数字转换为二进制字符串
  const binaryString = number.toString(2);

  // 拆分二进制字符串成8位一组的子字符串
  const binaryChunks = binaryString.match(/.{1,8}/g);

  // 将每个子字符串转换为十进制数值，并存储在Uint8Array中
  const uint8Array = new Uint8Array(binaryChunks.length);
  for (let i = 0; i < binaryChunks.length; i++) {
    const decimalValue = parseInt(binaryChunks[i], 2);
    uint8Array[i] = decimalValue;
  }

  return uint8Array;
}

// 示例用法
const number = 123456789;
const uint8Array = splitToUint8Array(number);
console.log(uint8Array);
