express - Node.js: curl: (52) Empty reply from server with space in request not encoded -

var http = require('http');  var server = http.createserver(function (request, response) {   response.writehead(200, {"content-type": "text/plain"});   response.end("hello world\n"); });  server.listen(8000); console.log("server running @ http://127.0.0.1:8000/"); 

i executed following curl commands:

curl "http://127.0.0.1:8000/" hello world  // space not encoded curl "http://127.0.0.1:8000/x y" curl: (52) empty reply server  curl "http://127.0.0.1:8000/x" hello world  // space encoded curl "http://127.0.0.1:8000/x%20y" hello world 

can please explain why curl 52???

in case, want send 500 back. can that?

even missing res.send looks issue route. meant.

app.get('/item/:id', function(...) {   .. }) 

note : before id. creates variable can accessed on req.params.id.
