## Install

### 1. [Install aria2c](https://aria2.github.io/)

Make sure aria2c is running and rpc is enabled, You can add this into /etc/rc.local
`/usr/local/bin/aria2c --enable-rpc --rpc-allow-origin-all -c -D`
> [Also See The Document of Aria2](https://aria2.github.io/manual/en/html/aria2c.html#rpc-interface)

### 2. Require Aria2.php

The codes just 82 lines but support all RPC methods. Using php's magic method `__call`

#### 2.1 Install by composer
`composer require daijie/aria2`

#### 2.2 Or copy Aria2.php

## Class Aria2

```php
Aria2 {
__construct ( string $server [, string $token ] )
__destruct ( void )
__call(string $name, array $arg)
public Object batch( [Callable $func ] )
public bool inBatch( void )
public array commit( void )
protected string req ( array $data )
}
```

## Usage

```php
$aria2 = new Aria2('http://127.0.0.1:6800/jsonrpc');
// http://127.0.0.1:6800/jsonrpc is the default value,
// equals to $aria2 = new Aria2
$aria2->getGlobalStat();
$aria2->tellActive();
$aria2->tellWaiting(0,1000);
$aria2->tellStopped(0,1000);
$aria2->addUri(
['https://www.google.com.hk/images/srpr/logo3w.png'],
['dir'=>'/tmp']
);
$aria2->tellStatus('1');
$aria2->removeDownloadResult('1');
//and more ...
```

#### Also See [Manual of Aria2 RPC Interface To Get The Method List](https://aria2.github.io/manual/en/html/aria2c.html#methods)

> .i.e, It's the example from Aria2 manual wrote in Python:

```python
>>> import urllib2, json, base64
>>> metalink = base64.b64encode(open('file.meta4').read())
>>> jsonreq = json.dumps({'jsonrpc':'2.0', 'id':'qwer',
... 'method':'aria2.addMetalink',
... 'params':[metalink]})
>>> c = urllib2.urlopen('http://localhost:6800/jsonrpc', jsonreq)
>>> c.read()
'{"id":"qwer","jsonrpc":"2.0","result":["2089b05ecca3d829"]}'
```

If you are using php with php-aria2:

```php
addMetalink($metalink);
#It means the method is aria2.addMetalink
print_r($c);
```

### Batch requests

Now php-aria2 support [JSON-RPC 2.0 Specification Batch requests](https://aria2.github.io/manual/en/html/aria2c.html#system.multicall)
In v1.2.0 batch requests have been introduced.

- `Aria2::batch` - Start batch mode
- `Aria2::inBatch` - Detect batch mode
- `Aria2::commit` - End batch mode and commit commands

```php
$aria2 = new Aria2('http://127.0.0.1:6800/jsonrpc');
$aria2->batch()
->getGlobalStat()
->tellActive()
->tellWaiting(0,1000)
->tellStopped(0,1000)
->addUri(
['https://www.google.com.hk/images/srpr/logo3w.png'],
['dir'=>'/tmp']
)
->commit();
```
Another ways is anonymous function, it also support method chaining. Don't forget commit.

```php
$aria2 = new Aria2('http://aria2:6800/jsonrpc', "token:e6c3778f-6361-4ed0-b126-f2cf8fca06db");
$aria2->batch(function($aria2){
$aria2->getGlobalStat();
$aria2->system_listMethods();
});
$status = $aria2->commit();
```

### System methods

- system.multicall
- system.listMethods
- system.listNotifications

There are some system methods, you can call it using

- Aria2::system_multicall
- Aria2::system_listMethods
- Aria2::system_listNotifications

php-aria2 convert `_` to `.` automatically. If method name without a `_`, php-aria2 will auto prepend a `aria2.`

```php
$aria2 = new Aria2('http://127.0.0.1:6800/jsonrpc');
$aria2->system_listMethods();
$aria2->getGlobalStat();
```

### Example #1: Download File

```php
$aria2->addUri(
['https://www.google.com.hk/images/srpr/logo3w.png'],
['dir'=>'/tmp']
);
```

## Docker Playground
#### require [docker-compose](https://docs.docker.com/compose/install/)

Docker playground: nginx (17 MB) + php7-fpm (82 MB) + aria2c (6 MB)

#### init playground

```shell
git clone https://github.com/shiny/php-aria2/
cd php-aria2/playground
docker-compose up
```

then open another terminal and enter playground

```shell
docker-compose exec php composer require daijie/aria2
```

for China user we suggest use the phpcomposer mirror

```shell
docker-compose exec php composer config repo.packagist composer https://packagist.phpcomposer.com
docker-compose exec php composer require daijie/aria2
```

#### After that, the playground structure:

## Updates

### v1.2.1b
- add batch anonymous function

### v1.2.0b

- Add system methods
- Add batch mode

### v1.1
Now support default token(secret) in php-aria2, compatible with v1.0

Before

```php
$aria2 = new Aria2('http://aria2:6800/jsonrpc');
$aria2->addUri(
"token:e6c3778f-6361-4ed0-b126-f2cf8fca06db",
['https://www.docker.com/sites/default/files/moby.svg']
);
$aria2->getGlobalStat("token:e6c3778f-6361-4ed0-b126-f2cf8fca06db");
```

After

```php
$aria2 = new Aria2('http://aria2:6800/jsonrpc', "token:e6c3778f-6361-4ed0-b126-f2cf8fca06db");
$aria2->addUri(
['https://www.docker.com/sites/default/files/moby.svg']
);
$status = $aria2->getGlobalStat();
```
