Parses SAML responses into JS objects you can read and manipulate.
$ npm install saml2js --save
Saml2js supports Node.js 0.10+ and iojs.
Saml2js was designed for use in any Node.js environment whether that's a web app or a standalone script.
var express = require('express')
Saml2js = require('saml2js'),
app = express();
app.post('/saml/callback/?', function(req, res, next){
var parser = new Saml2js(res.body.SAMLResponse);
res.json(parser.toObject());
});
app.listen(3000);To instantiate a new SAML parser:
var Saml2js = require('saml2js');
var parser = new Saml2js(SAMLResponse);After passing your SAML response as a string to the constructor you now have access to the following methods.
Returns the parsed SAML as a JavaScript object.
var parsedObject = parser.toObject();
Note that if your SAML has attributes have a Name attribute that contains a string that is mixed case and contains spaces Saml2js will automatically camel case this name when it is added as a property on the resulting object.
Example:
Given the following SAML...
<saml2:Attribute Name="First Name">
<saml2:AttributeValue>John</saml2:AttributeValue>
</saml2:Attribute>The resulting JavaScript object returned from Saml2js().toObject() will look like this:
{
firstName: 'John'
}Returns parsed SAML as a JSON string. Once you've instantiated the module and passed it raw SAML you can get its value as a JSON string with parser.toJSON().
Returns the value of a SAML attribute by name. The name you pass to this function should be the same as what the attribute value in your SAML is. For example, given this SAML:
<saml2:Attribute Name="First Name">
<saml2:AttributeValue>John</saml2:AttributeValue>
</saml2:Attribute>To get the value of First Name you would call it like this:
// assuming you've instantiated the library as `parser` with `new Saml2js(SAMLResponse)`...
var firstName = parser.get('first name');
console.log(firstName); //=> 'John'You don't need to worry about case sensitivity. Internally the Lodash .camelCase() method is called on the string you pass so when it is compared against the parsed SAML it will automagically match the name of the key as its stored internally if it exists.
This is a private method. It is called internally when you pass your SAML to the constructor. You should never need to call this manually. See the source code if you want to know more about it.
Testing requires Mocha and Chai.
