如何为golang 框架开发扩展

// Package myextension defines an interface for custom extensions.
package myextension

// Extension defines the interface for custom extensions.
type Extension interface {
    // DoSomething defines a method that can be implemented by custom extensions.
    DoSomething(args map[string]interface{}) error
}

// Package myextension defines an extension that implements the Extension interface.
package myextension

import "context"

// MyExtension is an extension that implements the Extension interface.
type MyExtension struct{}

// DoSomething implements the DoSomething method of the Extension interface.
func (e *MyExtension) DoSomething(args map[string]interface{}) error {
    // Do something with the args
    return nil
}

func init() {
    // Register the extension with the framework.
    RegisterExtension("myextension", func() Extension {
        return &MyExtension{}
    })
}

import (
    "context"

    "github.com/myframework/framework"
)

func main() {
    // Create a new framework instance.
    fw, err := framework.New()
    if err != nil {
        // Handle error
    }

    // Load extensions.
    err = fw.LoadExtensions(context.Background())
    if err != nil {
        // Handle error
    }

    // Use the extension.
    ext, err := fw.GetExtension("myextension")
    if err != nil {
        // Handle error
    }

    args := map[string]interface{}{"foo": "bar"}
    ext.DoSomething(args)
}
