【问题描述】:
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 将其显示在我的索引页面上?
错误
Error: Failed to lookup view "index" in views directory "C:\test\views"
index.ejs

<script>
//Declare the var with the data
var Result = <%- JSON.stringify(result) %>;
var TableData = null;
$(function () {
function ajusTables() {
$('.table').css('width', '100%');
$('.dataTables_scrollHeadInner').css('width', '100%');
}
TableData = $('#tblData').DataTable({
"serverSide": false,
"drawCallback": function (settings) {
ajusTables();
},
"scrollX": true,
"processing": true,
"paging": true,
"lengthChange": false,
"searching": true,

"autoWidth": true,
"deferRender": true,
"columns": [
{ "data": "Name" },
{ "data": "Message" },
],
"order": [0, "asc"]
});
console.log(Result);
TableData.rows.add(Result)
TableData.draw();
});
</script>
</body>
</html>
我安装了 EJS 包,在 html 中使用 Javascript 并从后端操作数据。
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');
});
【问题讨论】:
-
错误说它在
C:\test\views中找不到索引视图所以问题是你在C:\test\views中有你的index.ejs吗? -
不,它在
C:\test。我没有名为 views 的文件夹 -
所以创建它并将文件放在那里
-
现在我得到这个错误:
Error: Failed to lookup view "index" in views directory "C:\test\views\views" -
您是否更改了代码中的任何内容?
res.render("index"这行你改了吗?
