I have the following code:
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));
app.post('/rasp', function(req, res) {
res.send("received");
res.send(req.body.data);
});
app.listen(process.env.PORT || 5000);
I used POSTMAN to see if it worked and apparently the "received" text is sent back, but the data parameter is blank. What could be the problem?
Basically, the client sends a request and waits for a single response from your server. Once the client receives that response, it stops waiting for another. Furthermore, Express only allows you to send one response per request (going along with the client stuff explained above). You may be able to change this setting, but I've never dealt with it, so my answer will be limited to that knowledge.
Your server is executing res.send('received'); and the response is handled. You cannot call res.send again. You should be getting an error on your server when you attempt the second call.
You should send all data that the client needs in the first (and only) res.send().
Server responses should not be handled like logging (ex: sending 'received', 'analyzing', etc). Keep the logging separate. The client doesn't want to know all that extra info, it just wants the expected data response.
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));
app.listen(process.env.PORT || 5000);
app.post('/rasp', function(req, res) {
res.send({received:true,data:req.body});
});
can you try this one and writing the response here
I believe your post body is "data=Some Value".
If you want to send multiple chunks of data, you should use res.write, and res.end. In your code change the following lines
res.send("received");
res.send(req.body.data);
to
res.write("received");
res.end(req.body.data);
res.send("received");? and if you addconsole.log(req.body);what is the result?
