request module POST JSON request using Cookies - json

Question

When I am using curl command or Postman I am getting proper response within 1 sec but request module is going into timeout most of the time, pls help.
I think I need to add code for -c cookie.txt -b cookie.txt'
curl https://example.com/cmd -H "Content-Type:application/json" -k -d '{"cmd":{"dlpktenc":{"id":0,"byte0":001,"byte1":532}}} -c cookie.txt -b cookie.txt'
request module:
var request = require('request');
request = request.defaults({jar: true});
request(
{ method: 'POST',
uri: 'https://example.com/login',
form:
{ user: username,
password: password
},
rejectUnauthorized: false,
},
function( err, res, body ){
if (!err){
console.log(JSON.parse(body));
var requestData = {"cmd":{"dlpktenc":{"id":0,"byte0":001,"byte1":532}}};
request(
{ method: 'POST',
uri: 'https://example.com/cmd',
header:{
'content-type': 'application/json',
},
json: requestData,
rejectUnauthorized: false
},
function( err, res, body ){
if (!err){
console.log(body);
} else console.log(err);
});
} else console.log(err);
});

Answer 1

In cURL, -d means (from the man pages, emphasis mine):
-d, --data
(HTTP) Sends the specified data in a POST request to the HTTP server,
in the same way that a browser does when a user has filled in an HTML
form and presses the submit button. This will cause curl to pass the
data to the server using the content-type
application/x-www-form-urlencoded. Compare to -F, --form.
...
See also --data-binary and --data-urlencode and --data-raw. This
option overrides -F, --form and -I, --head and --upload.
If curl is working with the command you said, you need to send your request the same way:
request({
method: 'POST',
uri: 'https://example.com/cmd',
header: {
// Correct content type
'content-type': 'x-www-form-urlencoded',
},
body: requestData,
rejectUnauthorized: false
},
function(err, res, body) {
if (!err) {
console.log(body);
} else console.log(err);
}
);

There is a problem in sending the body in the request module as an object unless the json option is set as true
var requestData = {
"cmd": {
"dlpktenc": {
"id": 0,
"byte0": 001,
"byte1": 532
}
}
};
request({
method: 'POST',
url: 'http://localhost:9007/mbe',
header: {
'content-type': 'application/json',
},
body: requestData,
rejectUnauthorized: false,
//THE NEXT LINE WAS MISSING IN YOUR CODE
json : true
},
function(err, res, body) {
if (!err) {
console.log(body);
} else console.log(err);
}
);
