我正在我的nodeJs示例中尝试使用express-validator,
我尝试对用户名和密码是否有效进行基本验证,
用户名必须是电子邮件地址,并且
密码长度必须至少为5个字符。
我正在使用official doc
以下是我尝试运行的示例代码-
const express = require('express');
const app = express();
const { check, validationResult } = require('express-validator/check');
app.use(express.json());
app.all('/*', function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', "GET, POST, PUT, PATCH, DELETE, OPTIONS");
res.header("Access-Control-Allow-Headers", 'Content-Type, Accept, X-Access-Token');
if (req.method == 'OPTIONS') {
res.status(200).end();
} else {
next();
}
});
app.post('/user', [
// username must be an email
check('username').isEmail(),
// password must be at least 5 chars long
check('password').isLength({ min: 5 })
], (req, res) => {
// Finds the validation errors in this request and wraps them in an object with handy functions
const errors = validationResult(req);
if (!errors.isEmpty()) {
return res.status(422).json({ errors: errors.array() });
}
User.create({
username: req.body.username,
password: req.body.password
}).then(user => res.json(user));
});
var server = app.listen(8085, function () {
var host = server.address().address
var port = server.address().port
console.log("Example app listening at http://%s:%s", host, port)
});
由于某些原因,尽管传递了有效的电子邮件作为用户名和5个字符长的密码,但验证仍然失败,
这是什么错误,有人可以帮忙吗?
