Question

我正在尝试从表单中捕获帖子数据，当我完成处理后，我希望它再次呈现index.html文件。

尽管当我尝试如下所示的代码时，我得到了一个错误。

错误：

Error: Cannot find module 'html'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15)
    at Function.Module._load (internal/modules/cjs/loader.js:507:25)

    at next (/Applications/XAMPP/xamppfiles/htdocs/controlpanel/node_modules/express/lib/router/route.js:137:13)

代码：

var express = require('express');
var session = require('express-session');
var app     = express();

app.use('/public', express.static('public'));
app.use( express.static('public/html') );

app.post('/', function(req, res, next) {
    console.log('start processing postdata...');
    next()
});

app.all('/', function(req, res) {
    res.render('html/index.html');
});

app.listen(2222);

对于GET方法，一切正常。仅POST请求导致此错误。

我在做什么错了？

预先感谢，

这是工作代码，如果渲染，则应使用sendFile。渲染已与视图一起使用。

'use strict';
let express = require('express');
// let session = require('express-session');
let app = express();

app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use('/public', express.static('public'));
app.use(express.static('public/html'));

app.post('/', function (req, res, next) {
    console.log('start processing post data...');
    next();
});

app.all('/', function (req, res) {
    res.sendFile('./index.html', {
        root: __dirname + '/public/html'
    });
});

app.listen(2222);

找不到模块错误-NodeJS Express.JS
