Question

代码应按以下方式工作：如果目标用户名和登录的用户名在同一斗争中，则不应创建斗争，而应将用户重定向到/arena。但是问题是，即使我完成战斗然后快速按F5键，也将再次创建具有相同用户和相同目标的新战斗。什么会导致此问题？

app.get('/arena/fight/user/:username', async (req, res) => {

    User.findById(req.session.userId).then((user) => {
        if(req.params.username === user.username) {
            return res.redirect('/arena');
        }
    });

    const target = await User.findOne({username: req.params.username});
    const user = await User.findById(req.session.userId);
    const fight = await TempFight.findOne({user: user.username});
    if(fight && target.username === fight.target) {
       return res.redirect('/arena');
    } else {
       const battleId = uuid4();
       const newtempFight = TempFight({
          target: target.username,
          user: user.username,
          code: battleId
       });
       await newtempFight.save();
    }


    if(req.session.userId) {        

     res.render(__dirname + '/views/arena/battle', {messages, user, enemy, userItems, enemyItems, liveitems, fights, lostFights});
    } else {
        return res.redirect('/');
    }
});
