Question

每当我在浏览器上运行我的网站时，我都会收到以下错误消息：http://localhost:3000。我正在努力解决这个问题。有没有其他方法或更好的方法从MySQL获取数据并使用Node.js在我的索引页面上显示它？

错误

Error: Failed to lookup view "index" in views directory "C:\test\views"

                TableData.rows.add(Result)
                TableData.draw();

我安装了EJS包，在html中使用Javascript并操纵后端的数据。

res.render("Index", {result: result});将调用Index.ejs传递带有数据的JSON。

app.js

var express = require('express');
var app = express();
var mysql = require('mysql');
var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false });

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use('/', express.static(__dirname + '/'));
app.set("view engine", "ejs");

var connection = mysql.createConnection({
    host: "localhost",
    user: "root",
    password: "",
    database: "mywebsite"
});

connection.connect();

app.get('/', function (req, res) {
    connection.query('SELECT * FROM chat', function(err, result, fields) {  
        connection.end();
        if (err) throw err;
        console.log("Data displayed");
        res.render("index", { result: result });
    });
});

app.listen(3000, function () {
    console.log('Connected to port 3000');
});

请在观看次数文件夹中创建 index.ejs 。

Answer 2

检查以确保文件名为index.ejs而不是Index.ejs（案例）。
