让 gpt 写了个 encode 函数，把网址加密一下替换掉 t 参数就能利用他的页面了

function encode(input) {
function encodeBase64(input) {
const base64 = btoa(input).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');
return base64;
}

// Step 1: Encode the input string to Base64
var base64Data = encodeBase64(encodeURIComponent(input));

// Step 2: Insert random characters
var randomChars1 = 'ABCDEFGHIJ'; // Example random chars, should be dynamically generated
var modifiedData1 = base64Data.slice(0, 1) + randomChars1 + base64Data.slice(1);

// Step 3: Encode the modified string to Base64 again
var doubleEncodedData = encodeBase64(modifiedData1);

// Step 4: Insert another set of random characters
var randomChars2 = 'KLMNOPQRST'; // Example random chars, should be dynamically generated
var modifiedData2 = doubleEncodedData.slice(0, 1) + randomChars2 + doubleEncodedData.slice(1);

// Step 5: Reverse the string
var encodedData = modifiedData2.split('').reverse().join('');

return encodedData;
}
