WS.JS

A WS-* client stack for node.js. Written in pure javascript!

Currently supports:

MTOM
WS-Security (username tokens, x.509 digital signature)
WS-Addressing (all versions)
HTTP(S)

For more information visit my blog or my twitter.

Install

Install with npm:

npm install ws.js

Usage

WS-Security (Username)

    var ws = require('ws.js')
      , Http = ws.Http
      , Security = ws.Security
      , UsernameToken = ws.UsernameToken

    var request =  '<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">' +
                      '<Header />' +
                        '<Body>' +
                          '<EchoString xmlns="http://tempuri.org/">' +
                            '<s>123</s>' +
                          '</EchoString>' +
                        '</Body>' +
                    '</Envelope>'

    var ctx =  { request: request
               , url: "http://service/security"
               , action: "http://tempuri.org/EchoString"
               , contentType: "text/xml"
               }


    var handlers =  [ new Security({}, [new UsernameToken({username: "yaron", password: "1234"})])
                    , new Http()
                    ]

    ws.send(handlers, ctx, function(ctx) {
      console.log("response: " + ctx.response);
    })

Notes:

By default incoming signatures are not validates. To validate these signatures when you create the security channel specify the validateResponseSignature parameter:

var sec = new ws.Security({"validateResponseSignature": true} ...

Next specify the server certificate (the public key corresponding to the server private sgining key):

sec.options.responseKeyInfoProvider = new FileKeyInfo("./examples/server_public.pem")

In the future the server certificate will be extracted from the BinarySecurityToken automatically (when available).

MTOM

    var ws = require('ws.js')
      , Http = ws.Http

                    '</s:Body>' +
                  '</s:Envelope>'

    var ctx = { request: request
