Javascript Express自定义管线参数自动取值

这是我的js代码。每当我输入自定义地址时，chrome就会给我一个错误，说“页面无法加载”，并自动为自定义路由参数接收多个输入，然后加载最后一个输入

假设我输入localhost:3000/home，我的自定义参数名的输出如下

//jshint esversion:6

const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const _ = require("lodash");

const app = express();

app.set('view engine', 'ejs');

app.use(express.static("public"));

mongoose.connect('mongodb+srv://admin-sonu:test123@cluster0.iglcf.mongodb.net/todolistDB', {

const workItems = [];

const itemsSchema = new mongoose.Schema({
  name: String
});

const Item = mongoose.model("Item", itemsSchema);

const item1 = new Item({
  name: "Buy Food"
});

const item2 = new Item({
  name: "Cook Food"
});

const item3 = new Item({
  name: "Eat Food"
});

let defaultItems = [item1, item2, item3];

app.get("/", function(req, res) {

  Item.find(function(err, items) {
    if (items.length === 0) {
      Item.insertMany(defaultItems, function(err) {
        if (err) {
          console.log(err);
        } else {
          console.log("Successfull");
        }
      });

  });

});

const listsSchema = new mongoose.Schema({

const List = mongoose.model("List", listsSchema);

app.get("/:customListName", function(req, res) {

        list.save();

        res.redirect("/:" + customList);
      }

  if (listName === "Today") {
    item.save();
    res.redirect("/");
  } else {

      foundList.items.push(item);
      foundList.save();

  } else {

  res.redirect("/");

// app.get("/work", function(req, res) {

app.get("/about", function(req, res) {
  res.render("about");
});

app.listen(3000, function() {
  console.log("Server started on port 3000");
});

您可能希望删除此处的冒号：res.redirect（“/：”+customList）-即只执行res.redirect（“/”+customList）。您可能还希望在实际重定向用户之前等待新列表的保存，以避免出现竞争情况。谢谢！成功了。我怎么看不到这样的东西。有一件事我仍然不知道它从哪里自动获取Faveicon.ico的输入。
