我一直在使用aws-amplify离子库,并想知道如何检查用户是否登录？我来自firebase背景所以这是完全不同的.这样我就可以根据用户的登录状态授予对某些页面的访问权限.在我的auth提供者中我导入Amplify {Auth}.我可以看到可以获得几个数据,但我不知道该使用什么.有currentUserPoolUser,getCurrentUser(),getSyncedUser(),currentAuthenticatedUser,currentSession,getCurrentUser(),userSession,currentUserCredentials,currentCredentials和currentUserInfo.我似乎无法找到任何这方面的任何文件.我阅读和观看的所有内容都会被覆盖,直到用户登录...这一切都应该在客户端完成吗？谢谢.

Invalid register options "value" must be an object每当我尝试运行hapi服务器时,我都会收到一个奇怪的错误.我似乎无法弄清楚这个问题.这是我的代码:

await server.register(require('hapi-auth-jwt2'), (err) => {
            if (err) console.log(err);

            server.auth.strategy('jwt', 'jwt', {
                key: secretKey,
                verifyOptions: { algorithms: ['HS256'] }
            });

            glob.sync('api/**/routes/*.js', {
                root: __dirname
            }).forEach(file => {
                const route = require(path.join(__dirname, file));
                server.route(route);
            });
        }).catch(err => {
            console.log(err);
        });

我也尝试了这个,我仍然得到错误:

const options = {
            key: secretKey,
            verifyOptions: { algorithms: ['HS256'] }
        };

await server.register({
            register: require('hapi-auth-jwt2'),
            options
        }, (err) => {
            if (err) console.log(err);
            // We're giving the strategy both a name …

我正在尝试使用这里的代码示例https://github.com/firebase/functions-samples/blob/master/authorized-https-endpoint/functions/index.js但我的云功能不断崩溃说

我不知道还有什么办法让它发挥作用。这是我到目前为止使用过的代码：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const cors = require('cors')({origin: true});

exports.savedProfiles = functions.https.onRequest((req, res) => {
    cors(req, res, () => {
        if ((!req.headers.authorization || !req.headers.authorization.includes('Bearer '))) {
            console.log(req.headers);
            console.error('No Firebase ID token was passed as a Bearer token in the Authorization …

这是我的导航栏,但我有问题.每个链接之间是一个很小的空间.当我快速地将它们悬停在它们上面时,它看起来并不好看.我该如何删除它？
