无法读取未定义的属性“代码”，解码Firebase ID令牌失败

我约有5％的请求间歇性地收到此错误，但我不确定为什么。似乎大多数时候都可以使用，但我想将其提高到100％。

客户

const authLink = setContext(async (_, { headers }) => {
    let token;
    if (firebase.auth().currentUser) {
        token = await firebase.auth().currentUser.getIdToken();
    }
    return {
        headers: {
            ...headers,
            authorization: `Bearer ${token}`,
        },
    };
});

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);

您的客户端代码将生成授权标头，Bearer undefined如果标头firebase.auth().currentUser为false。该授权标头将不会导致no token登录到服务器代码中（其长度为16）。服务器代码将在运行时失败firebase.auth().verifyIdToken('undefined')。

您需要阻止客户端发送请求（如果firebase.auth().currentUser错误），或者捕获服务器代码中的未定义令牌。

注意：在模板字符串中使用未定义的变量会导致字符串“未定义”（不是空字符串）。
