basic-auth
Generic basic auth Authorization header field parser for whatever.
Installation
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
$ npm install basic-auth
API
var auth = require('basic-auth')
auth(req)
Get the basic auth credentials from the given request. The Authorization
header is parsed and if the header is invalid, undefined is returned,
otherwise an object with name and pass properties.
auth.parse(string)
Parse a basic auth authorization header string. This will return an object
with name and pass properties, or undefined if the string is invalid.
Example
Pass a Node.js request object to the module export. If parsing fails
undefined is returned, otherwise an object with .name and .pass.
var auth = require('basic-auth')
var user = auth(req)
// => { name: 'something', pass: 'whatever' }
A header string from any other location can also be parsed with
auth.parse, for example a Proxy-Authorization header:
var auth = require('basic-auth')
var user = auth.parse(req.getHeader('Proxy-Authorization'))
With vanilla node.js http server
var http = require('http')
var auth = require('basic-auth')
// Create server
var server = http.createServer(function (req, res) {
var credentials = auth(req)
if (!credentials || credentials.name !== 'john' || credentials.pass !== 'secret') {
res.statusCode = 401
res.setHeader('WWW-Authenticate', 'Basic realm="example"')
res.end('Access denied')
} else {
res.end('Access granted')
}
})
// Listen
server.listen(3000)
