将证书和密钥作为字符串传递给ListenAndServeTLS

package main

import (
	"crypto/tls"
	"fmt"
	"log"
	"net/http"
)

func main() {
	cert, err := tls.X509KeyPair([]byte(certString), []byte(keyString))
	if err != nil {
		log.Fatal(err)
	}

	server := &http.Server{
		Addr: ":443",
		TLSConfig: &tls.Config{
			Certificates: []tls.Certificate{cert},
		},
	}

	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(w, "Hello, World!")
	})

	err = server.ListenAndServeTLS("", "")
	if err != nil {
		log.Fatal(err)
	}
}

const certString = `
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
`

const keyString = `
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
`
