我是后期新手，我无法使用快速发布方法 . 我创建了一个名为new.ejs的文件，其中包含一个重定向到URL的表单http://localhost:3000/campgrounds/
new.ejs file
<% include partials/header %>
<h1>Create a new campground</h1>
<form action="campgrounds" method="POST">
<input type="text" name='name' placeholder="name" >
<input type="text" name='image' placeholder="img-url">
<button>Submit!</button>
</form>
<% include partials/footer %>
我查看了我的index.js文件，但我没有看到任何问题 . 但当我点击提交按钮时，如果 http://localhost:3000/campgrounds/ ，它会将我重定向到 http://localhost:3000/campgrounds/campgrounds
index.js file
const express = require('express');
const app = express();
const bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({extended: true}));
app.set('view engine', 'ejs');
let campgrounds = [
{name: "salmon creek", image: "https://pixabay.com/get/e837b1072af4003ed1584d05fb1d4e97e07ee3d21cac104491f4c278a7eeb1bc_340.jpg"},
{name: "Granite Hill", image: "https://pixabay.com/get/e83db7082af3043ed1584d05fb1d4e97e07ee3d21cac104491f4c278a7eeb1bc_340.jpg"},
{name: "Mountain Goat's Rest", image: "https://pixabay.com/get/ef3cb00b2af01c22d2524518b7444795ea76e5d004b0144591f3c079a4e9b1_340.jpg"}
]
app.get('/', (req, res) => {
res.render('landing');
});
app.get('/campgrounds', (req, res) => {
res.render("campgrounds", {campgrounds: campgrounds});
});
app.post('/campgrounds', (req, res) => {
let name = req.body.name;
let image = req.body.image;
let newCampground= {name: name, image: image}
campgrounds.push(newCampground);
res.redirect('/campgrounds')
});
app.get('/campgrounds/new', (req, res) => {
res.render('new')
});
app.listen(3000, () => {
console.log('Now serving app listening on port 3000!');
});
我无法得到这个app.post工作 . 但所有其他app.get方法工作正常 .

您需要为操作添加前导斜杠 .
发生这种情况是因为只使用
campgrounds使其相对于您当前所在的路径，即http://localhost:3000/campgrounds，因此它会将您发送到http://localhost:3000/campgrounds/campgrounds.
