Caddy Server Certmagic - 无效的内存地址

Question

我正在尝试使用 certmagic 设置服务器，但每次我运行代码时，我都会收到下面的堆栈消息，我在网上看到的所有地方都说你只需要做 certmagic.HTTPS([]string{"my-domain.com"}, router)但这里一定少了什么？

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x6dd407]

代码是目前的最低限度，只是从头开始，了解它是如何工作的，然后再考虑将其扩展到其他项目

package main

import (
    "github.com/caddyserver/certmagic"
    "github.com/gorilla/mux"
    "log"
    "net/http"
)

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/", func (w http.ResponseWriter, r *http.Request) {
        _, _ = w.Write([]byte("Hello world"))
    })
    log.Fatal(certmagic.HTTPS([]string{"my-domain.com"}, router))
}

甚至更简单（以及 certmagic 上提供的示例）得到相同的错误堆栈

func main() {
    handler := http.HandlerFunc(func (w http.ResponseWriter, r *http.Request) {
        _, _ = w.Write([]byte("Hello world"))
    })
    certmagic.HTTPS([]string{"my-domain.com"}, handler)
}

这是 certmagic 中的已知错误，已修复并合并。

您可以在此处查看详细信息：https://github.com/caddyserver/certmagic/pull/135

他们似乎经常发布，所以可以等待几天等待新版本，或者同时使用主分支而不是 v0.14.0。
