将Caddy导入go项目失败依赖性

Question

我想将Caddy导入一个go项目，但我似乎无法提出最基本的例子。 我尝试用dep或go mod拉动依赖关系，两者都失败了。

dep init

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

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？

可能不是最好的解决方案，但我做了什么：

1. 阅读https://github.com/mholt/caddy/blob/v0.11.5/vendor/manifest中供应商文件夹中的清单
2. 获取有问题的导入修订版
3. 修改require部分中的版本
