"JavaScript 将 [object Object] 转换为 JSON"

Question

I am implementing a token based authentication and I need to access the token I have set when i check if the user is authenticated.

function isAuthenticated(req, res, next) {
    const token = req.headers['authorization'];
    console.log(token);
    if (token) {
        req.token = token;
        next();
    } else {
        res.sendStatus(401);
    }
}

Answer 1

Unfortunately, the string "[object Object]"<\/code> doesn't have enough information to recreate back the original object. You'll have to debug the logic and find out why req.headers['authorization']<\/code> has such value in the first place.

Answer 2

Use JSON.stringify

function isAuthenticated(req, res, next) {
    const token = req.headers['authorization'];
    console.log(JSON.stringify(token));
    if (token) {
        req.token = token;
        next();
    } else {
        res.sendStatus(401);
    }
}
