Node.js 无法读取属性'；代码'；未定义的，解码Firebase ID令牌失败

我在大约5%的请求中间歇性地遇到这个错误，我不知道为什么。它似乎在大多数情况下都有效，但我想让它达到100%

服务器

            let token = req.headers.authorization;

            if (!token || !token.length) {
                console.log('no token');
            }

            token = token.split('Bearer ')[1];

            // validate JWT and pluck user id
            const { uid } = await firebase.auth().verifyIdToken(token);

            // find the user based on id
            const user = await firebase.auth().getUser(uid);

如果

firebase.auth（）.currentUser

为false，则客户端代码将导致授权头

Bearer undefined

。此授权标头不会导致

在服务器代码中记录任何令牌（其长度为16）。运行
firebase.auth（）.verifyIdToken（'undefined'）
时，服务器代码将失败

如果
firebase.auth（）.currentUser
为false，则需要阻止客户端发送请求，或者捕获服务器代码中未定义的令牌

注意：在模板字符串中使用未定义变量会导致字符串“未定义”（不是空字符串）

            let token = req.headers.authorization;

            if (!token || !token.length) {
                console.log('no token');
            }

            token = token.split('Bearer ')[1];

            // validate JWT and pluck user id
            const { uid } = await firebase.auth().verifyIdToken(token);

            // find the user based on id
            const user = await firebase.auth().getUser(uid);
