I try to retrieve plain-text-data from POST request but get [object Object] data. I have read much about express undefined issue, but that was always json, but I need plain/text or just string. Ok json is also for delivering strings, but I wonder if we can use just without json, but plain text.
So I did like this:
import express from 'express';
import bodyParser from 'body-parser';
const app = express()
const urlencodedParser = bodyParser.urlencoded({ extended: false })
app.post('/login', urlencodedParser, function (req, res) {
console.log(req.body)
res.send('welcome, ' + req.body)
})
app.listen(3000, () => {
console.log('Example app listening on port 3000!');
console.log('http://localhost:3000');
});
$ curl -X POST -H 'content-type: plain/text' --data "Hello world!" http://localhost:3000/login
welcome, [object Object]u@h ~/Dropbox/heroku/post-process
$
edit I corrected the curl command for "text/plain" and it not worked
$ curl -X POST -H 'content-type: text/plain' --data "Hello world!" http://localhost:3000/login
welcome, [object Object]u@h ~/Dropbox/heroku/post-process
$
Request header has wrong content-type, it should be: content-type: text/plain
And it's easy to handle with bodyParser.text for plain/text request instead urlEncoded. Because urlEncoded waits json data from request by default. Documentation reference
Here is your code with text parser and right content-type:
import express from 'express';
import bodyParser from 'body-parser';
const app = express()
const textParser = bodyParser.text({
extended: false
})
app.post('/login', textParser, function (req, res) {
console.log(req.body)
res.send('welcome, ' + req.body)
})
app.listen(3000, () => {
console.log('Example app listening on port 3000!');
console.log('http://localhost:3000');
});
$ curl -X POST -H 'content-type: text/plain' --data "Hello world!" http://localhost:3000/login
