Oclc-wskey NPM

node-oclc-wskey

Module to construct a WebService Key for use with OCLC services.

npm install oclc-wskey

usage

`var key = new WSKey(publicKey, secret /, user /)`

Where user is an object with the keys principalID and principalIDNS. Depending on what you're planning, you may not need to provide a one.

You can also pass an object as the sole parameter. Use these keys:

key	value
`public`	the public key
`secret`	the secret key
`user`	an object with `principalID` and `principalIDNS` keys
`redirect_uri`	redirect uri associated with the key
`scope`	an array of scopes associated with the key

redirect_uri and scope have no bearing on this module's only function (key.HMACSignature), but are necessary for generating Access Tokens.

`var sig = key.HMACSignature(method, uri /, user /)`

Returns an HMAC signature for method and uri. Uses the instantiated user by default, but can be overridden with a different user.

example

var WSKey = require('oclc-wskey')
var https = require('https')
var url = require('url')
var me = { principalID: 'principalID', principalIDNS: 'principalIDNS' }
var key = new WSKey('wskey', 'secret', me)
var addr = url.parse('https://circ.sd00.worldcat.org/LHR?q=oclc:656296916')

var opts = {
  hostname: addr.hostname,
  path: addr.path,
  headers: {
    'Authorization': key.HMACSignature('GET', url.format(addr)),
    'Accept': 'application/json'
  }
}

https.get(opts, function (res) {
  res.pipe(process.stdout)
})
