How do I construct the JSON data with session info for creating node? I am using Drupal 7 and the Services module 7.x-3.2. I am using Postman for Chrome (a http client) to test the API. 

What I want to do is log in a user and create a node with the user using the Drupal service API. 

I logged in the user with JSON POST request to http://example.com/api/user/login.


  


I successfully got the JSON result.

{
    "sessid": "KrZjlcY3rFr8v6iLoskcVQN9DmDWsg5yZqIjBeydEBY",
    "session_name": "SESS9fe39db36ccd7afd64e034fefa0129e1",
    "user": {
        "uid": "31",
        "name": "test_user",
        "mail": "services_user_2@example.com",
        "theme": "",
        "signature": "",
        "signature_format": "filtered_html",
        "created": "1352985941",
        "access": "1352991170",
        "login": 1352991510,
        "status": "1",
        "timezone": "",
        "language": "",
        "picture": null,
        "init": "services_user_2@example.com",
        "data": false,
        "roles": {
            "2": "authenticated user"
        },
        "rdf_mapping": {
            "rdftype": [
                "sioc:UserAccount"
            ],
            "name": {
                "predicates": [
                    "foaf:name"
                ]
            },
            "homepage": {
                "predicates": [
                    "foaf:page"
                ],
                "type": "rel"
            }
        }
    }
}


Then I tried to create an article via the API by sending the JSON POST request. (The user has the permission to create Article nodes.)


  


I got a 401 Unauthorized response. 

I guess I need to include the session cookie information to send the POST request, to create a node.

I have the session information previously returned. 

"sessid": "KrZjlcY3rFr8v6iLoskcVQN9DmDWsg5yZqIjBeydEBY",
"session_name": "SESS9fe39db36ccd7afd64e034fefa0129e1",


How can I utilize it to make a successful JSON POST request for creating a node?
{
   "title": "Just another drupal Post",
   "type": "Article"
}


notice no comma after the type:article tag so that your json works.
