This example shows the use of JavaScript with the vSphere Automation SDK for REST to send a session creation request to the vCenter Server Appliance using vCenter Single Sign-On credentials. The example retrieves a session cookie for future authentication. The JavaScript code depends on the Node.js package, which allows it to run standalone.

This example depends on the following global variables.

■

my_vcsa_host

■

my_sso_username

■

my_sso_password

■

my_http_options

For clarity, this example specifies a complete set of HTTP options for the NodeJS request, rather than retaining and modifying an existing object. 

var https = require('https');
var httpPort = 443;
var httpPath = '/rest/com/vmware/cis/session';
var httpMethod = 'POST';

// Prepare the HTTP request.
my_http_options = {
  host: my_vcsa_host,
  port: httpPort,
  path: httpPath,
  method: httpMethod,
  rejectUnauthorized: false,
  requestCert: true,
  agent: false,
  auth: my_sso_username + ":" + my_sso_password
};

// Define the callbacks.
function callback(res) {
  console.log("STATUS: " + res.statusCode);
  res.on('error', function(err) { console.log("ERROR in SSO authentication: ", err) });
  res.on('data', function(chunk) {});
  res.on('end', function() {
    if (res.statusCode == 200) {
      // Save session ID authentication.
      var cookieValue = res.headers['set-cookie'];
      my_http_options.headers = {'Cookie': cookieValue};
      // Remove username-password authentication.
      my_http_options.auth = {};
  }
  console.log("Session ID:\n" + res.headers['set-cookie']);
};

// Issue the session creation request.
https.request(my_http_options, callback).end();
