当前,当我创建路由时,我检查Auth0方法-isAuthenticated()-确定是否返回受保护的页面或重定向到登录。但是,此状态仅存在于内存中,不会在刷新浏览器时将用户保留在其页面上,我想这样做。
这是一个React / RR4 / React Context应用,我的Auth0方法列在Auth.js中(如下)。
强烈建议将登录状态存储在localStorage中。而且,如果我将Auth0令牌存储在cookie中,由于没有设置服务器验证,因此我不确定如何验证令牌。什么条件可以检查以确保安全的数据持久性?
ProtectedRoutes.jsx:
<Route
exact
key={route.path}
path={route.path}
render={() => (
// CONDITION TO CHECK
context.auth.isAuthenticated()
? (
<div>
<route.component />
</div>
) : <Redirect to="/login" />
)}
/>
Auth.js(已添加供参考):
import auth0 from 'auth0-js';
import authConfig from './auth0-variables';
class Auth {
accessToken;
idToken;
expiresAt;
tokenRenewalTimeout;
auth0 = new auth0.WebAuth({
domain: authConfig.domain,
clientID: authConfig.clientId,
redirectUri: authConfig.callbackUrl,
responseType: 'token id_token',
scope: 'openid'
});
constructor() {
this.scheduleRenewal();
this.login = this.login.bind(this);
this.logout = this.logout.bind(this);
this.handleAuthentication = this.handleAuthentication.bind(this);
this.isAuthenticated = this.isAuthenticated.bind(this);
this.getAccessToken = this.getAccessToken.bind(this);
this.getIdToken = this.getIdToken.bind(this);
this.renewSession = this.renewSession.bind(this);
this.scheduleRenewal = this.scheduleRenewal.bind(this);
}
login() {
console.log('logging in!');
this.auth0.authorize();
}
handleAuthentication() {
return new Promise((resolve, reject) => {
this.auth0.parseHash((err, authResult) => {
if (err) return reject(err);
console.log(authResult);
if (!authResult || !authResult.idToken) {
return reject(err);
}
this.setSession(authResult);
resolve();
});
});
}
getAccessToken() {
return this.accessToken;
}
getIdToken() {
return this.idToken;
}
getExpiration() {
return new Date(this.expiresAt);
}
isAuthenticated() {
let expiresAt = this.expiresAt;
return new Date().getTime() < expiresAt;
}
setSession(authResult) {
localStorage.setItem('isLoggedIn', 'true');
let expiresAt = (authResult.expiresIn * 1000) + new Date().getTime();
this.accessToken = authResult.accessToken;
this.idToken = authResult.idToken;
this.expiresAt = expiresAt;
this.scheduleRenewal();
}
renewSession() {
this.auth0.checkSession({}, (err, authResult) => {
if (authResult && authResult.accessToken && authResult.idToken) {
this.setSession(authResult);
} else if (err) {
this.logout();
console.log(`Could not get a new token. (${err.error}: ${err.error_description})`);
}
});
}
scheduleRenewal() {
let expiresAt = this.expiresAt;
const timeout = expiresAt - Date.now();
if (timeout > 0) {
this.tokenRenewalTimeout = setTimeout(() => {
this.renewSession();
}, timeout);
}
}
logout() {
this.accessToken = null;
this.idToken = null;
this.expiresAt = 0;
localStorage.removeItem('isLoggedIn');
clearTimeout(this.tokenRenewalTimeout);
console.log('logged out!');
}
}
export default Auth;
答案 0 :(得分:1)
您可以使用Silent authentication在刷新浏览器时更新令牌。
专门针对您的React SPA应用
tokenRenewed
到false
的状态renewToken
中已经有一个auth.js
方法,因此请在componentDidMount
方法中调用它componentDidMount() {
this.auth.renewToken(() => {
this.setState({tokenRenewed : true});
})
}
renewToken
以接受如下所示的回调cb
renewSession(cb) {
this.auth0.checkSession({}, (err, authResult) => {
if (authResult && authResult.accessToken && authResult.idToken) {
this.setSession(authResult);
} else if (err) {
this.logout();
console.log(`Could not get a new token. (${err.error}: ${err.error_description})`);
}
if(cb) cb(err, authResult);
});
}
tokenRenewed
为true
(即您通过静默身份验证更新了有效令牌),否则不要加载应用程序组件render() {
if(!this.state.tokenRenewed) return "loading...";
return (
// Your App component
);
}
