import ( "github.com/juju/juju/state" "gopkg.in/mgo.v2" ) func getEnvironConfig(url string, environName string) (*state.EnvironConfig, error) { mongoSession, err := mgo.Dial(url) if err != nil { return nil, err } st, err := state.NewState(mongoSession, nil) if err != nil { return nil, err } environ, err := st.Environment(environName) if err != nil { return nil, err } return environ.Config() }This function creates a connection to the Juju state server using an MongoDB URL, then retrieves the `state.State` object for the given environment name. From there, it uses the `Environment.Config()` method to retrieve the `EnvironConfig` object for the environment. This is a package library that can be used by Go applications that need to interact with Juju environments. It is specifically designed for use with Juju, and provides a convenient way to query and manipulate Juju state programmatically.
