I'm having an issue where my req.body is always undefined when I do a POST. I'm using NodeJS, Express and BodyParser. Everything else I can find online says I need the include .json(), as below on the 1st line, but this didn't sort the issue. I've also tried with {extended: true} which also didn't help.
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({extended: false}));
app.use(express.static(path.join(__dirname, 'public')));
app.use(cookieParser());
app.use(
session({
secret: 'my secret',
resave: false,
saveUninitialized: false,
store: site
})
);
If I run a line of code like req.body.text I'll just get undefined as the result. Does anyone know what my mistake might be?
body parser is deprecated see https://stackoverflow.com/a/68127336/10772577.
Sending a post request to a route with 'Content-Type': 'application/json' should give you a body.
Example express route.
app.post('/api', function(request, response){
console.log(request.body); // your JSON
response.send(request.body); // echo the result back
});
See https://expressjs.com/en/guide/routing.html
Example client request.
const response = await fetch('/api', {
method: 'POST',
body: JSON.stringify(object),
headers: {
'Content-Type': 'application/json'
}
});
See https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch
const app = express();
/* EXPRESS BODY PARSER */
app.use(express.json());
const myFunction(req,res) = async (req,res) => {
const body = req.body;
}
