英文:
Error while building my server [Route.get() requires a callback function]
问题
我在构建服务器时遇到了错误，但我不知道如何修复。有没有办法修复这个错误？谢谢！我附上了服务器页面以及我的路由，这样你就可以看到我在做什么了。错误信息也在下面列出。非常感谢！
错误信息：
SyntaxError: 箭头函数参数列表格式错误
server.js：
const express = require("express");
const cors = require("cors");
const bodyParser = require("body-parser");
const app = express();
const mongoose = require("mongoose");
const port = process.env.PORT || 5000;
app.use(bodyParser.json());
app.use(cors());
app.use(
bodyParser.urlencoded({
extended: false
})
);
const mongoURI = "";
mongoose
.connect(mongoURI, { useNewUrlParser: true })
.then(() => console.log('Mongodb connected'))
.catch(err => console.log(err));
const Users = require('./routes/Users');
app.use('/users', Users);
app.listen(port, () => {
console.log('Server is running on port.');
});
以下是routes/Users.js的更多代码：
const express = require("express");
const users = express.Router();
const cors = require("cors");
const jwt = require("jsonwebtoken");
const bcrypt = require("bcrypt");
const User = require("../models/User");
users.use(cors());
process.env.SECRET_KEY = 'secret';
users.post('/register', (req, res) => {
const today = new Date();
const userData = {
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
password: req.body.password,
created: today
};
User.findOne({
email: req.body.email
})
.then(user => {
if (!user) {
bcrypt.hash(req.body.password, 10, (err, hash) => {
userData.password = hash;
User.create(userData)
.then(user => {
res.json({ status: user.email + 'registered' });
})
.catch(err => {
res.send('error: ' + err);
});
});
} else {
res.json({ error: 'User already exists' });
}
})
.catch(err => {
res.send('error:' + err);
});
});
module.exports = users;
希望这有助于解决你的问题！如果还有其他问题，请随时提问。

Error:

const port = process.env.PORT || 5000

Here is more code from routes.
routes/Users.js
const express = require("express")
const users = express.Router()
const cors = require("cors")
const jwt = require("jsonwebtoken")
const bcrypt = require("bcrypt")
const User = require("../models/User")
users.use(cors())
process.env.SECRET_KEY = 'secret'
users.post('/register' (req, res) => {
const today = new Date();
const userData = {
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
password: req.body.password,
created: today
}
User.findOne({
email: req.body.email
})
.then(user => {
if(!user) {
bcrypt.hash(req.body.password, 10, (err, hash) => {
userData.password = hash
User.create(userData)
.then(user => {
res.json({status: user.email + 'registered'})
})
.catch(err => {
res.send('error: ' + err)
})
})
} else {
res.json({error: 'User already exists'})
}
})
.catch(err => {
res.send('error:' err)
})
})
module.export = users

更改：
users.post('/register' (req, res) => {
为：
users.post('/register', (req, res) => {
英文:
Its a simple typo mistake
change
users.post('/register' (req, res) => {
TO
users.post('/register', (req, res) => {
