如何将用户限制为只有一个post请求

Question

我在做一个交友应用程序。我想限制用户只能发布一个帖子。这是我到目前为止所知道的：

router.post("/", middleware.isLoggedIn, (req, res) => {
    //get data from form and add to friendfinder array
    var rank = req.body.rank;
    var discord = req.body.discord;
    var valorantid = req.body.valorantid;
    var author  = {
        id: req.user._id,
        username: req.user.username,
    };
    var newFriend = {rank:rank, discord:discord, valorantid:valorantid, author:author};
        //create a new friend finder entry

    Lookinglist.create(newFriend, function(err, newlyCreated){
        if(err){
            console.log(err);
        } else {
            //redirect back to frinedfinder page
            res.redirect("friendfinder");
        }
    });
});

你有去/friendfinder的路线吗？如果是，请使用以下命令

res.redirect("friendfinder");
