I have a file that roughly looks like this:
const
express = require('express'),
cookieParser = require('cookie-parser'),
http = require('http'),
path = require('path'),
bodyParser = require('body-parser'),
app = express(),
server = http.createServer(app);
app.use(bodyParser.urlencoded({extended: true}));
app.use(express.static(path.join(__dirname,'./pub')));
app.use(cookieParser());
app.get('/', (req,res) => {
res.sendFile(path.join(__dirname,'./index.html'));
});
app.post('/test', (req, res) => {
console.log(req.query); //returns empty object even though it shouldn't
// does other stuff here
});
server.listen(3000, function() {
console.log('server is listening on port: 3000');
});Calling foo.bar/test.html?query=foobar returns an html login form that sends the request to the /test route on submit - and I'd expect the output of the console.log above to be { query: "foobar }, but it's empty.
Everything else in the app works as intended (the request for the login, saving the session, etc) with the exception of the query string.
The request form:
<!DOCTYPE html>
<html lang = "en">
<head>
<meta charset = "UTF-8">
<title>Login</title>
</head>
<body>
<form action="/test" method="POST">
<fieldset>
<label for="email">Email</label>
<input type ="email" id="email" name="email" placeholder="[email protected]" required>
<label for="password">Password</label>
<input type="password" id="password" name="password" required>
<button type ="submit">Submit</button>
</fieldset>
</form>
</body>
</html>CodePudding user response：
When doing a request using a html form, the props can be accessed using req.body . The data is not sent using querystring (so it's not added to the url) but added to the request payload.
Here's code to read out the data from request.
app.post('/test', (req, res) => {
console.log('in login:')
console.log(JSON.stringify(req.body)); // use req.body since there's no querystring.
res.status(200).send('Login succeeded for user ' req.body.email)
});

Here are the possible solutions that you can try:
Make sure when you test the API, you use POST method since you have used POST method in the route.
Also, the API URL should be of the form http://localhost:3000/user?name=Karliah. This should print { name : 'Karliah'}
