看看我能不能帮上忙
第一种方法是不带任何库的js

const randomizer = (length) =>{
  const pullOfChars = "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz1234567890";
  const generatedArrayOfChars = Array.from(
    { length: length },
    (v, k) => pullOfChars[Math.floor(Math.random() * pullOfChars.length)].toString(16)
  );

  const randomizedString = generatedArrayOfChars.join("");
  return randomizedString
  
}

console.log(randomizer(10))

或者您可以使用node js crypto的

const crypto = require('crypto');

const randomString1 = crypto.randomBytes(10).toString('hex');
console.log(randomString1);

希望能有所帮助
