|
|
Generic basic auth Authorization header field parser for whatever.
|
|
|
|
## Installation
|
|
|
|
This is a [Node.js](https://nodejs.org/en/) module available through the
|
|
[npm registry](https://www.npmjs.com/). Installation is done using the
|
|
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
|
|
|
```
|
|
$ npm install basic-auth
|
|
```
|
|
|
|
## API
|
|
|
|
<!-- eslint-disable no-unused-vars -->
|
|
|
|
```js
|
|
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`.
|
|
|
|
<!-- eslint-disable no-unused-vars, no-undef -->
|
|
|
|
```js
|
|
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:
|
|
|
|
<!-- eslint-disable no-unused-vars, no-undef -->
|
|
|
|
```js
|
|
var auth = require('basic-auth')
|
|
var user = auth.parse(req.getHeader('Proxy-Authorization'))
|
|
```
|
|
|
|
### With vanilla node.js http server
|
|
|
|
```js
|
|
var http = require('http')
|
|
var auth = require('basic-auth')
|
|
var compare = require('tsscmp')
|
|
|
|
// Create server
|
|
var server = http.createServer(function (req, res) {
|
|
var credentials = auth(req)
|
|
|
|
// Check credentials
|
|
// The "check" function will typically be against your user store
|
|
if (!credentials || !check(credentials.name, credentials.pass)) {
|
|
res.statusCode = 401
|
|
res.setHeader('WWW-Authenticate', 'Basic realm="example"')
|
|
res.end('Access denied')
|
|
} else {
|
|
res.end('Access granted')
|
|
}
|
|
})
|
|
|
|
// Basic function to validate credentials for example
|
|
function check (name, pass) {
|
|
var valid = true
|
|
|
|
// Simple method to prevent short-circut and use timing-safe compare
|
|
valid = compare(name, 'john') && valid
|
|
valid = compare(pass, 'secret') && valid
|
|
|
|
return valid
|
|
}
|
|
|
|
// Listen
|
|
server.listen(3000)
|
|
```
