Javascript NodeJS-ejs：如何在登录/注册表单上运行密码检查

我创建了一个登录页面作为一个小例子。 表单会询问用户名、密码等常见问题，还会要求用户确认密码，如果长度不同，则会抛出一个错误，警告用户存在差异

如果我输入正确的

密码

和

确认密码

长度

如果

password

与

confirm password

不相等，则不工作，错误如下：

错误：无法在视图目录中查找视图“/注册” “/home/emanuele/Desktop/cashman tracker仪表板/视图” 位于Function.render（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/application.js:580:17） 在ServerResponse.render（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/response.js:1012:7） 在ServerResponse.res.render（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express ejs layouts/lib/express layouts.js:77:18） at/home/emanuele/Desktop/cashman tracker仪表板/routes/users.js:30:7 在Layer.handle[作为handle_请求]（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/Layer.js:95:5） 下一步（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/route.js:137:13） 在Route.dispatch（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/Route.js:112:3） 在Layer.handle[作为handle_请求]（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/Layer.js:95:5） at/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:281:22 在Function.process_参数（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:335:12） 下一步（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:275:10） 位于Function.handle（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:174:3） 在路由器上（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:47:12） 在Layer.handle[作为handle_请求]（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/Layer.js:95:5） 在trim_前缀（/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:317:13） at/home/emanuele/Desktop/cashman tracker dashboard/node_modules/express/lib/router/index.js:284:7

以下是带有相关检查的代码：

users.js

const express = require('express');
const router = express.Router();

// Login Page
router.get('/login', (req, res) => res.render('login'));
// Register Page
router.get('/register', (req, res) => res.render('register'));

// Register Handle
router.post('/register', (req, res) => {
    const { name, email, password, password2 } = req.body;
    let errors = [];

    // Check required fields
    if (!name || !email || !password || !password2) {
        errors.push({ msg: 'Please fill in all fields' });
    }
    // Check password
    if (password !== password2) {
        errors.push({ msg: 'Passwords do not match' });
    }
    // Check password length
    if (password.length < 6) {
        errors.push({ msg: 'Password should be at least 6 characters' });
    }
    if (errors.length > 0) {
        res.render('register', {
            errors,
            name,

    } else {

    }
});

如果有用，我还将附加项目树的打印屏幕：

问题似乎是下面在register.ejs中的陈述，但我不知道

        <% include ./partials/messages %>

我不知道消息.ejs是否也与错误有关

到目前为止我所做的：

我查看了不同的来源，这就是我使用的来源。我反复检查了很多次，但错误仍然存在，当我输入长度为X的密码并确认长度为X+1的密码时，我就出现了那个奇怪的错误

我不确定错误是否与messages.ejs或语句

有关，或者是否与其他内容有关

感谢您为我指出了解决此问题的正确方向。

我一直在尝试您的代码，它工作正常，唯一一行不工作的是：

您必须使用以下代码更改此行：

我希望它能帮助你
