HarmonyOS transmit 参数 ，字符串转16进制数组

如果两位字符表示16进制，参考如下方法

function stringToHex(str:string):number[]{
  let hexNumbers: number[] = [];
  for (let i = 0; i < str.length/2; i++) {
    let charCode1 = Number.parseInt(str[i*2],16);
    let charCode2 = Number.parseInt(str[i*2+1],16);

    let hexNumber = charCode1*16 + charCode2
    console.debug(hexNumber.toString(16))
    hexNumbers.push(hexNumber);
  }
  return hexNumbers;
}
