I'm sending the following JSON string to my server.
(
{
id = 1;
name = foo;
},
{
id = 2;
name = bar;
}
)
On the server I have this.
app.post('/', function(request, response) {
console.log("Got response: " + response.statusCode);
response.on('data', function(chunk) {
queryResponse+=chunk;
console.log('data');
});
response.on('end', function(){
console.log('end');
});
});
When I send the string, it shows that I got a 200 response, but those other two methods never run. Why is that?
I think you're conflating the use of the response
object with that of the request
.
The response
object is for sending the HTTP response back to the calling client, whereas you are wanting to access the body of the request
. See this answer which provides some guidance.
If you are using valid JSON and are POSTing it with Content-Type: application/json
, then you can use the bodyParser
middleware to parse the request body and place the result in request.body
of your route.
var express = require('express')
, app = express.createServer();
app.use(express.bodyParser());
app.post('/', function(request, response){
console.log(request.body); // your JSON
response.send(request.body); // echo the result back
});
app.listen(3000);
Test along the lines of:
$ curl -d '{"MyKey":"My Value"}' -H "Content-Type: application/json" http://127.0.0.1:3000/
{"MyKey":"My Value"}
For Express v4+
install body-parser from the npm.
$ npm install body-parser
https://www.npmjs.org/package/body-parser#installation
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res, next) {
console.log(req.body) // populated!
next()
})
