node.js - 请求超时问题 - Node/Heroku

Question

下面的这个 post 路由超时大约 1/100 次。我正在尝试优化代码以避免这些超时，但它们继续发生。我可以做些什么来进一步避免这些请求超时？
我不知道如何解决这个问题。这条路线的发布时间不应超过 30 秒。
谢谢你的帮助!

router.post("/updateAccount", usernameToLowerCase, async function(req, res){
    
   
    if (req.user) {
    
    await User.findOne({username: req.body.currentUser}, function(err, user) {
    console.log('first ' + user)
    if (err) {
    console.log('cant find user err' + err)
    return done(err);
    }
    
    user.username = req.body.username;
    user.password = req.body.password;
    user.accountUpdated = true;
    
    
    user.save(function(err){
    
    if (err) {
    req.flash("error", "It looks like that email address is taken. Please use a different email address");
    res.redirect('back');
    
    } else {
    
    req.logout();
    
    req.login(user, function(err) {

    if (err) console.log('There was an account error' + err)
    req.flash("success", "Your account has been created! Your username is " + user.username );
    res.redirect('/results')
    
    });
    }
    });
    });
    
    }
    });

您可以使用 findOneAndUpdate找到匹配的文档，根据更新参数更新它

try{
    let filter = {username: req.body.currentUser};
    let user = {
        username = req.body.username;
        password = req.body.password;
        accountUpdated = true
    } 
    let user = await User.findOneAndUpdate(filter, user,{
        select: "_id username",
        new: true,
    });
    req.logout();
    req.login(user, function(err) {
        if (err) console.log('There was an account error' + err)
        req.flash("success", "Your account has been created! Your username is " + user.username );
        res.redirect('/results')
        });
}
catch(error){
    console.log(error)
    req.flash("error", "It looks like that email address is taken. Please use a different email address");
    res.redirect('back');
    //handle error
}
