把URL转为大写16进制

代码如下 

 let url = 'https://www.baidu.com'
  function strUpCaseCode(url) {
    if (url === "") {
      return "";
    }
    let upCaseCode = [];
    upCaseCode.push("");
    for (var i = 0; i < url.length; i++) {
      upCaseCode.push((url.charCodeAt(i)).toString(16));
    }
    let urlCode = upCaseCode.join("").toUpperCase();
    console.log(urlCode)
  }

  strUpCaseCode(url)
