Determine address of proxied request
|
|
|
|
## Install
|
|
|
|
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 proxy-addr
|
|
```
|
|
|
|
## API
|
|
|
|
```js
|
|
var proxyaddr = require('proxy-addr')
|
|
```
|
|
|
|
### proxyaddr(req, trust)
|
|
|
|
Return the address of the request, using the given `trust` parameter.
|
|
|
|
The `trust` argument is a function that returns `true` if you trust
|
|
the address, `false` if you don't. The closest untrusted address is
|
|
returned.
|
|
|
|
```js
|
|
proxyaddr(req, function (addr) { return addr === '127.0.0.1' })
|
|
proxyaddr(req, function (addr, i) { return i < 1 })
|
|
```
|
|
|
|
The `trust` arugment may also be a single IP address string or an
|
|
array of trusted addresses, as plain IP addresses, CIDR-formatted
|
|
strings, or IP/netmask strings.
|
|
|
|
```js
|
|
proxyaddr(req, '127.0.0.1')
|
|
proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8'])
|
|
proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0'])
|
|
```
|
|
|
|
This module also supports IPv6. Your IPv6 addresses will be normalized
|
|
automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`).
|
|
|
|
```js
|
|
proxyaddr(req, '::1')
|
|
proxyaddr(req, ['::1/128', 'fe80::/10'])
|
|
```
|
|
|
|
This module will automatically work with IPv4-mapped IPv6 addresses
|
|
as well to support node.js in IPv6-only mode. This means that you do
|
|
not have to specify both `::ffff:a00:1` and `10.0.0.1`.
|
|
|
|
As a convenience, this module also takes certain pre-defined names
|
|
in addition to IP addresses, which expand into IP addresses:
|
|
|
|
```js
|
|
proxyaddr(req, 'loopback')
|
|
proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64'])
|
|
```
|
|
|
|
* `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and
|
|
`127.0.0.1`).
|
|
* `linklocal`: IPv4 and IPv6 link-local addresses (like
|
|
`fe80::1:1:1:1` and `169.254.0.1`).
|
|
* `uniquelocal`: IPv4 private addresses and IPv6 unique-local
|
|
addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`).
|
|
|
|
When `trust` is specified as a function, it will be called for each
|
|
address to determine if it is a trusted address. The function is
|
|
given two arguments: `addr` and `i`, where `addr` is a string of
|
|
the address to check and `i` is a number that represents the distance
|
|
from the socket address.
|
|
|
|
### proxyaddr.all(req, [trust])
|
|
|
|
Return all the addresses of the request, optionally stopping at the
|
|
first untrusted. This array is ordered from closest to furthest
|
|
(i.e. `arr[0] === req.connection.remoteAddress`).
|
|
|
|
```js
|
|
proxyaddr.all(req)
|
|
```
|
|
|
|
The optional `trust` argument takes the same arguments as `trust`
|
|
does in `proxyaddr(req, trust)`.
|
|
|
|
```js
|
|
proxyaddr.all(req, 'loopback')
|
|
```
|
|
|
|
### proxyaddr.compile(val)
|
|
|
|
Compiles argument `val` into a `trust` function. This function takes
|
|
the same arguments as `trust` does in `proxyaddr(req, trust)` and
|
|
returns a function suitable for `proxyaddr(req, trust)`.
|
|
|
|
```js
|
|
var trust = proxyaddr.compile('loopback')
|
|
var addr = proxyaddr(req, trust)
|
|
```
|
|
|
|
This function is meant to be optimized for use against every request.
|
|
It is recommend to compile a trust function up-front for the trusted
|
|
configuration and pass that to `proxyaddr(req, trust)` for each request.
|
|
|
|

|
|
$ npm test
|
|
```
|
|
|
|
## Benchmarks
