So this is my client:
handleSubmit(event) { event.preventDefault(); alert(`starting to stream ${this.state.value} at ${this.state.volume}`) fetch('/emitter', {
method: 'post',
body: JSON.stringify({
value: this.state.value,
volume: this.state.volume
}),
headers: {"Content-Type": "application/json"}
});
alert(`${this.state.value} and ${this.state.volume} sent to server`) };
and this is my server:
app.use(express.static(__dirname + '/build'));
app.all('*', function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS');
res.header('Access-Control-Allow-Headers', 'Content-Type');
next();
});
app.use(bodyParser.urlencoded({
extended: true
}));
app.post('/emitter', function (req, res) {
console.log(req.body)
});
I'm simply trying to send data from an input form to a server. Why am I getting an empty {}
when I received the req.body
in the server?
EDIT:
For reference, this is the answer: https://github.com/github/fetch/issues/323#issuecomment-277510957
app.use(bodyParser.json());
needs to added after or before:
app.use(bodyParser.urlencoded({
extended: true
}));
