I'm trying to log all the data and then return it as a response.
app.post('/data', (req, res) => {
const data = req.body
console.log(data)
return res.json({
data
})
})
I'm sending data with Postman. In the Body tab I have "raw" selected and "JSON (application/json)". Headers tab is Content-Type application/json. I'm sending this:
{
"aa": 23
}
When I click send button all I get is an empty object and the data variable is undefined in my console.log. How to fix it? I double checked everything. It should work, but it doesn't.
Alright, I found the solution.
"As body-parser module is used to parse the body and urls, it should be called before any call to 'req.body...'."
So I did this:
import bodyParser from 'body-parser'
const app = express()
app.use(bodyParser.urlencoded())
app.use(bodyParser.json())
app.post('/data', (req, res) => {
const data = req.body
console.log(data)
return res.json({
data
})
})
And now it works fine.
It seems like you're passing an invalid value to res.JSON(). Try:
return res.json(data);
