我附上了注册表和验证代码 (Node.js)，如下所示。我已经尝试验证来自注册表的用户输入，但没有成功!但成功存储到MongoDB数据库中。
<form action="/register" method="POST">
<input type="text" name="name" placeholder="username"><br>
<input type="password" name="userpass" placeholder="password"><br>
<input type="submit" name="submit" value="send">
</form>
router.post('/register', function(req, res, next) {
// Get user input from register form
let nam = req.body.name;
let pass = req.body.userpass;
req.checkBody('nam', 'Name is required').notEmpty();
req.checkBody('pass', 'Pass is required').notEmpty();
var errors = req.validationErrors();
if(errors){
console.log(errors)
}
else {
var newUser = new User({
username:nam,
pass:pass
});
User.createUser(newUser,function(err,user){
if(err) throw err;
console.log(user);
});
res.location('/register');
res.redirect('/register');
}
我在运行代码时得到了这个结果。
GET /register 304 25.699 ms - -
[ { param: 'nam', msg: 'Name is required', value: undefined },
{ param: 'pass', msg: 'Pass is required', value: undefined } ]
最佳答案
下面的代码应该可以工作，我认为主要问题是使用实际的表单变量名称(name、userpass):
index.js
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const expressValidator = require('express-validator');
app.use(express.static('./'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(expressValidator());
var router = express.Router();
app.use("/", router);
router.post('/register', function(req, res, next) {
console.log('/register POST body: ', req.body);
/* Check form variables. */
req.checkBody('name', 'Name is required').notEmpty();
req.checkBody('userpass', 'Pass is required').notEmpty();
var errors = req.validationErrors();
if (errors) {
console.error("Validation errors occurred: ", errors);
res.status(400).json({ status: "Bad Request" });
return;
}
console.log("Validation successful");
// Get user input from register form
let nam = req.body.name;
let pass = req.body.userpass;
var newUser = new User({
username:nam,
pass:pass
});
User.createUser(newUser,function(err,user){
if(err) throw err;
console.log(user);
});
res.location('/register');
res.redirect('/register');
});
app.listen(3000);
index.html
<!doctype html>
<html lang="en">
<body>
<form action="/register" method="POST">
<input type="text" name="name" placeholder="username"><br>
<input type="password" name="userpass" placeholder="password"><br>
<input type="submit" name="submit" value="send">
</form>
</body>
</html>
关于javascript - 无法使用 Express-validator 验证用户输入，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54035326/
