|
|
Generic basic auth Authorization header field parser for whatever.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
$ npm install basic-auth
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
```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.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Pass a node request or koa Context object to the module exported. If
|
||
|
|
parsing fails `undefined` is returned, otherwise an object with
|
||
|
|
`.name` and `.pass`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
var auth = require('basic-auth');
|
||
|
|
var user = auth(req);
|
||
|
|
// => { name: 'something', pass: 'whatever' }
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
### With vanilla node.js http server
|
||
|
|
|
||
|
|
```js
|
||
|
|
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)
|
||
|
|
```
