Question

如果用户在数组中，是否可以使用Express来呈现用户页面？像

这样的东西

var express = require("express");
var app = express();
var users = ["Community", "bjskistad", "sindresorhus"]

app.get(null, function(req, res){
    for(var i in array){
        if(i in array){
            app.get("/"+i, function(req, res){
                res.send(//whatever);
            }
        }
    }
}

这可能吗？或者Express只显示静态页面？

有效的方法是

var express = require("express");
var app = express();
var users = ["Community", "bjskistad", "sindresorhus"]

app.get("/:user", function(req, res){ //the username is a path parameter
    var curentUser = req.params.user; //retrieve the username
    if(users.indexOf(currentUser)>-1){ //check if user is in array
        res.send(/*whatever*/);       //send the expected page
        //or 
        //res.redirect(/*whatever else*/); //or redirect to another url
    } else {
        res.send(/*403 page*/);
    }
}

在If中使用Express Route？
