将保存在cookie中的密码自动填入表单：库js-cookie

// login.vue
getCookie() {const username = Cookies.get("username");const password = Cookies.get("password");const rememberMe = Cookies.get('rememberMe')this.loginForm = {username: username === undefined ? this.loginForm.username : username,password: password === undefined ? this.loginForm.password : decrypt(password),rememberMe: rememberMe === undefined ? false : Boolean(rememberMe)};},

记住密码，这里期限是30天：

Cookies.set("username", this.loginForm.username, { expires: 30 });
Cookies.set("password", encrypt(this.loginForm.password), { expires: 30 });
Cookies.set('rememberMe', this.loginForm.rememberMe, { expires: 30 });

这里有加密和解密的操作。在线生成RSA的公钥和私钥，使用JSEncrypt库进行加密和解密：

// 加密
export function encrypt(txt) {const encryptor = new JSEncrypt()encryptor.setPublicKey(publicKey) // 设置公钥return encryptor.encrypt(txt) // 对数据进行加密
}// 解密
export function decrypt(txt) {const encryptor = new JSEncrypt()encryptor.setPrivateKey(privateKey) // 设置私钥return encryptor.decrypt(txt) // 对数据进行解密
}
