阿里 CDN 方式1

计算方式

import CryptoJS from "crypto-js";

const generateHash = (url, key) => {
  // Generate 10-digit timestamp
  const ts = Math.floor(Date.now() / 1000).toString();

  // Generate UUID and remove hyphens
  const uid = crypto.randomUUID().replace(/-/g, "");

  // Create input string
  const input = `${url}-${ts}-${uid}-0-${key}`;

  // Calculate MD5 hash
  const hashResult = CryptoJS.MD5(input);
  const hashValue = hashResult.toString(CryptoJS.enc.Hex);

  // Generate auth_key string
  const authKeyValue = `auth_key=${ts}-${uid}-0-${hashValue}`;

  return { hash: hashValue, timestamp: ts, uuid: uid, authKey: authKeyValue };
};

uid 是 随机数，并不一定非要是 uuid ，使用 0 也是可以的。
