字符串转换16进制

具体实现:

/**
* 字符串转换16进制进制
* @returns {string}
* @param str
*/
strToHexadecimal(str) {
  let val = '';
  for (let i = 0; i < str.length; i++) {
    if (val === '') val = str.charCodeAt(i).toString(16);
    else val += str.charCodeAt(i).toString(16);
  }
  val += '0a';
  return val;
},
  /**
  * 16进制转换字符串
  * @param str
  * @returns {string}
  */
  hexadecimalToStr(hex) {
    const arr = hex.split('');
    let out = '';
    for (let i = 0; i < arr.length / 2; i++) {
      const tmp = `0x${arr[i * 2]}${arr[i * 2 + 1]}`;
      const charValue = String.fromCharCode(tmp);
      out += charValue;
    }
    return out;
  },

// 测试
// 字符串16进制加密
const strToHex = utils.strToHexadecimal(
      encodeURIComponent('测试数据123123abc'),
);
log.i(strToHex, '字符串16进制加密---------');
const hexToStr = utils.hexadecimalToStr(strToHex);
log.i(decodeURIComponent(hexToStr), '字符串16进制转换回来的---------');
