我正在尝试使用Firebase自定义令牌和会话cookie实施登录机制,以确保我做错了事,但我无法弄清楚。

我将放置代码,然后说明如何使用它进行测试。

前端代码

const functions = firebase.functions();
const auth = firebase.auth();

auth.setPersistence(firebase.auth.Auth.Persistence.NONE);

auth.onAuthStateChanged((user) => {
    if (user) {
        user.getIdToken()
            .then((idToken) => { 
                console.log(idToken);
            });
    }
});

function testCustomLogin(token) {
    firebase.auth().signInWithCustomToken(token)
    .then((signInToken) => {
        console.log("Login OK");
        console.log("signInToken", signInToken);
        signInToken.user.getIdToken()
        .then((usertoken) => {
            let data = {
                token: usertoken
            };
            fetch("/logincookiesession", {
                method: "POST", 
                body: JSON.stringify(data)
            }).then((res) => {
                console.log("Request complete! response:", res);
                console.log("firebase signout");
                auth.signOut()
                    .then(()=> {
                        console.log("redirecting ....");
                        window.location.assign('/');
                        return;
                    })
                    .catch(() => {
                        console.log("error during firebase.signOut");
                    });
                
            });
        });
    })
    .catch(function(error) {
        // Handle Errors here.
        var errorCode = error.code;
        var errorMessage = error.message;
        console.log(errorCode, errorMessage);
    });      
}

后端代码

app.post('/logincookiesession', (req, res) => {
    let token = req.body.token;

    // Set session expiration to 5 days.
    const expiresIn = 60 * 60 * 24 * 5 * 1000;
    // Create the session cookie. This will also verify the ID token in the process.
    // The session cookie will have the same claims as the ID token.
    // To only allow session cookie setting on recent sign-in, auth_time in ID token
    // can be checked to ensure user was recently signed in before creating a session cookie.
    admin.auth().createSessionCookie(token, {expiresIn})
    .then((sessionCookie) => {
        // Set cookie policy for session cookie.
        const options = {maxAge: expiresIn, httpOnly: true, secure: true};
        res.cookie('session', sessionCookie, options);
        res.end(JSON.stringify({status: 'success'}));
    })
    .catch((error) => {
        res.status(401).send('UNAUTHORIZED REQUEST!' + JSON.stringify(error));
    });
});

app.get('/logintest', (req, res) => {
    let userId = 'jcm@email.com';
    let additionalClaims = {
        premiumAccount: true
    };

    admin.auth().createCustomToken(userId, additionalClaims)
    .then(function(customToken) {
        res.send(customToken);
    })
    .catch(function(error) {
        console.log('Error creating custom token:', error);
    });
});

所以基本上我要做的是

  1. 执行firebase emulators:start
  2. 手动在我的浏览器http://localhost:5000/logintest上执行此操作,这给了我在浏览器中打印的令牌
  3. 然后在另一个具有登录表单的页面中,打开浏览器的javascript控制台,执行javascript函数testCustomLogin,然后将步骤2中的令牌作为参数传递。

在网络流量中,我看到对/logincookiesession的呼叫返回了此消息:

UNAUTHORIZED REQUEST!{"code":"auth/invalid-id-token","message":"The provided ID token is not a valid Firebase ID token."}

我完全迷路了。

我可以在firebase控制台的“身份验证”部分中看到已创建并登录了用户jcm@email.com,但是无法创建会话cookie。

请,我在这里需要一些建议。

答案 0 :(得分:0)

创建cookie会话的路由出错。

它应该这样开始。

aNumber = nf.format(new Double(aNumber));

我使用的代码来自手册OMG。我希望这也会对某人有所帮助。
