js对表单base64加密

// 获取表单数据
const formData = new FormData(document.querySelector('form'));

// 将表单数据转换为JSON对象
const formDataObject = {};
formData.forEach((value, key) => {
    formDataObject[key] = value;
});

// 将JSON对象转换为字符串
const jsonString = JSON.stringify(formDataObject);

// 对字符串进行Base64编码
const encodedData = btoa(jsonString);

console.log('Encoded Data:', encodedData);

function urlSafeBase64Encode(str) {
    return btoa(str).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');
}

const encodedData = urlSafeBase64Encode(jsonString);
console.log('URL Safe Encoded Data:', encodedData);

function urlSafeBase64Decode(str) {
    str += Array(5 - str.length % 4).join('=');
    return atob(str.replace(/-/g, '+').replace(/_/g, '/'));
}

const decodedData = urlSafeBase64Decode(encodedData);
console.log('Decoded Data:', JSON.parse(decodedData));
