我有一个nodejs应用程序,每次我尝试使用命令“node index.js”启动应用程序时都会抛出错误:
app.post('/login', async (req, res) => {
^
SyntaxError: Unexpected token (
我知道这个错误有多普遍,但我需要一点指导。此应用程序专门针对rocket.chats文档中详细介绍的iframe auth,用于使用第三方API而不是rocket chat的本机登录系统进行登录。
应用程序的完整代码如下:
var express = require('express');
var bodyParser = require('body-parser');
var request = require('request-promise');
var session = require('express-session');
const cookieParser = require('cookie-parser');
var app = express();
const rocketChatServer = '*redacted*';
const rocketChatAdminUserId = '*redacted*';
const rocketChatAdminAuthToken = '*redacted*';
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
//CORS in case you need
app.use((req, res, next) => {
res.set('Access-Control-Allow-Origin', '*redacted*');
res.set('Access-Control-Allow-Credentials', 'true');
next();
});
// define middleware
const middleware = [
cookieParser(),
session({
secret: 'super-secret-key',
key: 'super-secret-cookie',
resave: true,
saveUninitialized: true,
cookie: { maxAge: 1209600000 } // two weeks in miliseconds
})
]
app.use(middleware);
//var createOrLoginUser = require('./rocketchat');
app.get('/', (req, res) => {
if(req.session.rocketchatAuthToken){
res.send(`
<html>
<body>
<iframe width='100%;' height='100%' src="*redacted*"
frameborder="0"></iframe>
</body>
</html>`);
}else{
res.send(`
<form method="post" action="/login">
<input type="text" placeholder="username" name="username">
<input type="text" placeholder="firstName"
name="firstname">
<input type="text" placeholder="Email" name="email">
<input type="text" placeholder="Pass" name="password">
<input type="submit" value="Submit">
</form>
`);
}
})
app.post('/login', async (req, res) => {
// ....CODE TO LOGIN USER
var username = req.body.username;
var pass = req.body.password;
var email = req.body.email;
var name = req.body.firstname;
// Creating or login user into Rocket chat
try {

const third_party_response = await request(options);
var result_third_party = JSON.parse(third_party_response);
console.log(result_third_party);
console.log(result_third_party.email);

const response = await request(options);
var result = JSON.parse(response);
req.session.rocketchatAuthToken = result.data.authToken;
res.redirect('/');
}else{
res.send('You are not registered with 3rd party API!');
}
} catch (ex) { console.log('CATHCh');
if (ex.statusCode === 401) {
// User does not exist, creating user
var options = { method: 'POST',

} else {
throw ex;
}
}
})
// This method will be called by Rocket.chat to fetch the login token
app.get('/api/v1/rocket_chat_auth_get', (req, res) => {
if (req.session.rocketchatAuthToken) {
res.send({ loginToken: req.session.rocketchatAuthToken })
return;
} else {
res.status(401).json({ message: 'User not logged in'});
return;
}
})
// This method will be called by Rocket.chat to fetch the login token

app.get('/api/v1/rocket_chat_iframe', (req, res) => {
const rocketChatServer = '*redacted*';
if (req.session.rocketchatAuthToken) {
return res.send(`<script>
window.parent.postMessage({

`)
return;
} else {

}
})
app.listen(3030, function () {
console.log('Example app listening on port 3030!');
});
