How to execute a Addon/Plugin (ExtractArchive) via API?

[henrydatei]

I've seen issue #4256 and wanted to implement it myself. I've set everything up, got a local instance of pyload running, made the gui changes which call an api endpoint http://127.0.0.1:8000/api/extract_package/1. I created the function that should be executed

@legacy("extractPackage")
@permission(Perms.MODIFY)
def extract_package(self, package_id):
    """
    Extracts a package with the ExtractArchive plugin.

    :param package_id: package id
    """
    # TODO: implement

but I'm now clueless on how to start the ExtractArchive plugin. The plugin works flawlessly, after a package has finished it automatically extracts the content. But how do I start this process via the API?

After a lot of debbing I might found the solution:

@legacy("extractPackage")
@permission(Perms.MODIFY)
def extract_package(self, package_id):
    """
    Extracts a package with the ExtractArchive plugin.

    :param package_id: package id
    """
    for plugin in self.pyload.addon_manager.plugins:
        if plugin.classname == 'ExtractArchive' and plugin.is_activated():
            package = self.pyload.files.get_package(package_id)
            plugin.package_finished(package)

I iterate through all plugins and if I find a plugin ExtractArchive and it is active I get the package by its id and call package_finished from the found plugin (which should be the extractor).
