我想使用 Windows 證書商店中的證書包，誰能告訴我我在這里做錯了什么？
我的代碼：
package main
import (
"fmt"
"runtime"
"github.com/google/certtostore"
)
type certmgr struct {
certToStore certtostore.CertStorage
}
func main() {
if runtime.GOOS == "windows" {
var cert certmgr
certInStore, err := cert.certToStore.Cert()
if err != nil {
fmt.Println("message", "Error in getting system store certificate ...")
}
fmt.Println("Windows System Store Certificate", *certInStore)
}
}
我得到的錯誤：
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x0 pc=0xbe2dda]
goroutine 1 [running]:
main.main()
C:/Users/prajwal.bhagat/go/src/phoenix/mainsvc/cmd/main/test.go:17 0x1a
exit status 2
uj5u.com熱心網友回復：
您可以使用類似 的庫google/certtostore，它是一個多平臺包，允許您在 Linux 上使用 x509 證書和在 Windows 上使用證書存盤。
它不直接獲取證書包，而是使用WindowscertGetCertificateChain呼叫，它從最終證書開始構建證書鏈背景關系，如果可能，回傳到受信任的根CA。
它由 使用CertWithContext()，它使用創建時提供的頒發者的值執行證書查找WinCertStore。
它回傳證書及其 Windows 背景關系，可用于執行其他操作，例如使用CertKey().
無效的記憶體地址或 nil 指標取消參考
你需要初始化var cert certmgr
更一般地說，您需要先獲取商店，如下例所示：
fmt.Println("open cert store")
// Open the local cert store. Provider generally shouldn't matter, so use Software which is ubiquitous. See comments in getHostKey.
store, err := certtostore.OpenWinCertStore(certtostore.ProviderMSSoftware, "", []string{"localhost"}, nil, false)
if err != nil {
fmt.Errorf("OpenWinCertStore: %v", err)
return
}
fmt.Println("get cert from cert store")
// Obtain the first cert matching all of container/issuers/intermediates in the store.
// This function is indifferent to the provider the store was opened with, as the store lists certs
// from all providers.
crt, context, err := store.CertWithContext()
if err != nil {
fmt.Println("failed to get cert from cert store. ", err)
return
}
if crt == nil {
fmt.Println("no cert")
return
}
fmt.Println("get key from cert")
// Obtain the private key from the cert. This *should* work regardless of provider because
// the key is directly linked to the certificate.
key, err := store.CertKey(context)
if err != nil {
fmt.Printf("private key not found in %s, %s", store.ProvName, err)
return
}
if key == nil {
fmt.Println("no key")
return
}
fmt.Printf("find cert '%s' with private key in container '%s', algo '%s'\n", crt.Subject, key.Container, key.AlgorithmGroup)
