I'm new to server-side development.
I'm trying to set up a node.js server that can receive posts.
My client-server code sends the post request:
function post(){
fetch('/clicked', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({a: 1, b: 'Text'})
})
.then(function(response){
if(response.ok){
console.log('POST success.');
return;
}
throw new Error('POST failed.');
})
.catch(function(error){
console.log(error);
});
}
And my Node.js server receives it:
const express = require('express');
const app = express();
app.use(express.json());
app.post('/clicked', (req, res) => {
console.log(req.a);
console.log(req.b);
console.log(req.body);
res.sendStatus(201);
})
However, my server console logs all undefined.
What should I do to receive my POST request body?
Try setting up express.json() inside the app:
const express = require('express');
const app = express();
app.use(express.json())
app.post('/clicked', (req, res) => {
console.log(req.a);
console.log(req.b);
console.log(req.body);
res.sendStatus(201);
});
