非常抱歉，我的回答中确实没有提供修改后的代码示例。下面是修正后的代码：
package mainimport ("crypto/x509""encoding/pem""fmt""github.com/tjfoc/gmsm/sm2")func main() {p10PEM := `-----BEGIN CERTIFICATE REQUEST-----MIIBFDCB9wIBADAUMRIwEAYDVQQDDAlsb2NhbGhvc3QwWTATBgcqhkjOPQIBBggqgRzPVAoGAIQA+DOcm1o+m7rzXrdJxSVuFxsfAx5FRKTzm/AQUzkfD6hfWp30O7lEDR8AWHOVYimr1we9N8MTZ4GFdm+/ioUqaYThvux05CZIRaC38y4bTN9ylfbg0atkLFU/Lil6UIlibtECAgMMMIHCBgcqgRzPVQGDdQUAMAsGCSqGSIb3DQEBCwOCAQEAbHBiqslIDZ84LWMdGVn3IMYYS/UYTuNu+Kbg/bmpXDpq93WZJ8tgGT/hMZsvNZkACxxz+EUPhbr+fOCBoHUyHXblchbhItDbcfByzbkr88joTOUCIH73fnDFpfA1/BDlTkgtnqrPrvEmRV06BaBWBiEqZOL28qKSYiJJlA==-----END CERTIFICATE REQUEST-----`block, _ := pem.Decode([]byte(p10PEM))if block == nil {fmt.Println("Failed to parse PEM block")return}req, err := x509.ParseCertificateRequest(block.Bytes)if err != nil {fmt.Println("Failed to parse certificate request:", err)return}publicKey, ok := req.PublicKey.(*sm2.PublicKey)if !ok {fmt.Println("Invalid public key type")return}fmt.Println("Public Key:")fmt.Printf("X: %x\n", publicKey.X.Bytes())fmt.Printf("Y: %x\n", publicKey.Y.Bytes())dn := req.Subject.ToRDNSequence()for _, attrSet := range dn {for _, attrTypeAndValue := range attrSet {attrType := attrTypeAndValue.Type.String()attrValue := fmt.Sprintf("%s", attrTypeAndValue.Value)fmt.Printf("%s: %s\n", attrType, attrValue)}}}
再次对之前的错误给您带来的困扰表示歉意，希望这次提供的代码能够正确运行。如果还有其他问题，请随时提问。
