Parse HTTP X-Forwarded-For header
|
||
|
|
|
||
|
|
## 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):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install forwarded
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
```js
|
||
|
|
var forwarded = require('forwarded')
|
||
|
|
```
|
||
|
|
|
||
|
|
### forwarded(req)
|
||
|
|
|
||
|
|
```js
|
||
|
|
var addresses = forwarded(req)
|
||
|
|
```
|
||
|
|
|
||
|
|
Parse the `X-Forwarded-For` header from the request. Returns an array
|
||
|
|
of the addresses, including the socket address for the `req`, in reverse
|
||
|
|
order (i.e. index `0` is the socket address and the last index is the
|
||
|
|
furthest address, typically the end-user).
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm test
|
||
|
|
```
