Simple api to manage aria2c via api

Add this line to your application's Gemfile:

gem 'aria2_driver'

And then execute:

$ bundle

Or install it yourself as:

$ gem install aria2_driver

aria2 = Aria2Driver::JsonRpc::Client.new 'hostname'

With the previous line of code you can create a client that will make requests to aria2c downloader running on hostname server accepting connections to port 80 with default http scheme. The client created as is will have a self generated client id (using SecureRandom).

aria2 = Aria2Driver::JsonRpc::Client.new 'hostname',
              {port: 9090, scheme: 'https', id: 'my', token: 'abcd-1234'}

With the code described above, you can override default connection parameters specifying also a custom client_id and a secret token. The latter will be used in any of the following requests and must match the --rpc-secret parameter specified in the aria2c configuration.

Aria2Driver allows you to make a generic request, via jsonrpc, in which you have to put the aria2 method and request parameters, as described below

response = aria2.request Aria2Driver::JsonRpc::Request.new 'aria2.addUri',
                         {params: [['http://www.example.com/a.jpg'], {"dir" => "/tmp/"}]}

it's also possible to make the same request as follow

response = aria2.add_uri {params: [['http://www.example.com/a.jpg'], {"dir" => "/tmp/"}]}

Aria2Driver request can lead to a valid aria2c response or to an exception (ResponseException) in case of a connection problem or any other kind of problem occurred in the communication with aria2c. You can check if a valid response is an 'error' one or a 'result' one checking the error? method as below

response = aria2.get_version
response.error?

If a response is an error one, the error getter returns you a simple ruby wrapper class of the jsonrpc error block, with code, message and the optional data

error = response.error

error.code # => -32700
error.message # => "Parse error"

If you get a non-error response, you can access the result in form of an hash obtained parsing the json result block in the aria2c response

response.result # => {"gid" => "2089b05ecca3d829", "status" => "active"}
