# Network Interface

Network interface information plugin for Cordova/PhoneGap that supports Android, Browser, iOS, and Windows 10.

## Command Line Install

```sh
cordova plugin add @red-mobile/cordova-plugin-networkinterface
```

### uninstall

```sh
cordova plugin remove @red-mobile/cordova-plugin-networkinterface
```

## PhoneGap Build

To include the Network Interface plugin in your PhoneGap Build application, add this to your config.xml:

```xml
<plugin name="cordova-plugin-networkinterface" source="npm" />
```

## Ionic 2+ (w/ Typescript) Usage

First install the wrapper:

```sh
npm install @ionic-native/network-interface
```

Define it in your modules:

```ts
import { NetworkInterface } from '@ionic-native/network-interface';

@NgModule( {
    ...
    providers: [
        NetworkInterface
    ],
} )
```

The Ionic wrapper functions return promises, so use them as follows:

```typescript
import { NetworkInterface } from '@ionic-native/network-interface';

constructor( private networkInterface: NetworkInterface ) {

  this.networkInterface.getWiFiIPAddress()
    .then(address => console.info(`IP: ${address.ip}, Subnet: ${address.subnet}`))
    .catch(error => console.error(`Unable to get IP: ${error}`));

  this.networkInterface.getCarrierIPAddress() {
    .then(address => console.info(`IP: ${address.ip}, Subnet: ${address.subnet}`))
    .catch(error => console.error(`Unable to get IP: ${error}`));

  const url = 'www.github.com';
  this.networkInterface.getHttpProxyInformation(url)
    .then(proxy => console.info(`Type: ${proxy.type}, Host: ${proxy.host}, Port: ${proxy.port}`))
    .catch(error => console.error(`Unable to get proxy info: ${error}`));
}
```

## Global Usage

The plugin creates the global object `networkinterface`, with the following methods:

* getWiFiIPAddress(onSuccess, onError)
* getCarrierIPAddress(onSuccess, onError)
* getHttpProxyInformation (url, onSuccess, onError)

### Using getWiFiIPAddress and getCarrierIPAddress

The onSuccess() callback has one argument object with the properties `ip` and `subnet` (changed in 2.x). The onError() callback is provided with a single value describing the error.

```javascript
function onSuccess( ipInformation ) {
  alert( "IP: " + ipInformation.ip + " subnet:" + ipInformation.subnet );
}

function onError( error ) {
  // Note: onError() will be called when an IP address can't be
  // found, e.g. WiFi is disabled, no SIM card, Airplane mode
  alert( error );
}

networkinterface.getWiFiIPAddress( onSuccess, onError );
networkinterface.getCarrierIPAddress( onSuccess, onError );
```

### Using getHttpProxyInformation

This function gets the relevant proxies for the passed URL in order of application. `onSuccess` we will get an array of objects, each having a `type`, `host` and `port` property. Where the url is not passed via a proxy, the `type` is "DIRECT" and both the host and port properties are set to "none"

```javascript
// The url you want to find out the proxies for.
const url = 'www.github.com';

function onSuccess( proxyInformation ) {
  proxyInformation.forEach( function( proxy ) {
    alert( "Type:" + proxy.type + " Host:" + proxy.host + " Port:" + proxt.port );
  });
}

function onError( error ) {

    // Note: onSuccess() will be called where there is no applicable proxy, not onError.
    alert( error );
}

networkinterface.getHttpProxyInformation( url, onSuccess, onError );
```

The type can be any of the following:

* DIRECT - Not passing through a proxy. `host`/`port` values will be "none"
* SOCKS
* HTTP
* HTTPS - iOS Only, seems to default back to HTTP
* AUTOJS - iOS Only, proxy determined by AutoConfiguration Script. `host`/`port` values will be "none"
* AUTOCONFIG - iOS Only, proxy determined by configuration at a URK `host`/`port` values will be "none"
