我想将 Caddy 导入到一个 go 项目中，但我似乎无法提出最基本的示例。我尝试使用 dep 或 go mod 拉取依赖项，但都失败了。

dep 初始化

No versions of golang.org/x/text met constraints:

go build(使用 go mod)

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()
}

那么我应该如何在自己的包中使用 Caddy？

最佳答案

你能试试这个吗:

module stack/cady

可能不是最好的解决方案，但我做了什么:

1. 阅读 vendor 文件夹中的 list https://github.com/mholt/caddy/blob/v0.11.5/vendor/manifest
2. 为遇到麻烦的导入获取修订
3. 修改require部分的版本
