我想导入Caddy一个 go 项目，但我似乎无法提出最基本的例子。我尝试拉依赖关系dep或go mod两者都失败了。
dep init

这是一个非常基本的脚本：
package main
import (
"fmt"
"io/ioutil"
"os"
"github.com/mholt/caddy"
_ "github.com/mholt/caddy/caddyhttp"
)
func init() {
caddy.SetDefaultCaddyfileLoader("default", caddy.LoaderFunc(loadConfig))
}
func loadConfig(serverType string) (caddy.Input, error) {
contents, err := ioutil.ReadFile(caddy.DefaultConfigFile)
if err != nil {
if os.IsNotExist(err) {
return nil, nil
}
return nil, err
}
fmt.Printf("Loading Caddyfile: %s\n", string(contents))
return caddy.CaddyfileInput{
Contents: contents,
Filepath: caddy.DefaultConfigFile,
ServerTypeName: serverType,
}, nil
}
func main() {
caddy.AppName = "MyApp"
caddy.AppVersion = "0.1"
caddyfile, err := caddy.LoadCaddyfile("http")
if err != nil {
panic(err)
}
inst, err := caddy.Start(caddyfile)
if err != nil {
panic(err)
}
inst.Wait()
}
那么我应该如何在我自己的包中使用 Caddy 呢？
