Golang Go语言 TLS 问题

用 Golang 写一个 TLS 隧道，不想验证域名(SNI)，双向验证两端证书是否为同个 CA 证书签发，该如何实现。。

试过 VerifyPeerCertificate 但是在本地网络下可以运行，到了远程就报错，不知为何

路过大佬求点拨，以下是两端配置，谢谢。。。

======== Server ======== tlsConfig := tls.Config{} tlsConfig.InsecureSkipVerify = true tlsConfig.ClientAuth = tls.RequireAndVerifyClientCert tlsConfig.Certificates = []tls.Certificate{func() tls.Certificate { CertKey, err := tls.X509KeyPair(ServerCert, ServerKey) if err != nil { panic(err) } return CertKey }()} tlsConfig.VerifyPeerCertificate = func(rawCerts [][]byte, verifiedChains [][]*x509.Certificate) error { Roots := x509.NewCertPool() Roots.AppendCertsFromPEM(CA) cert, _ := x509.ParseCertificate(rawCerts[0]) opts := x509.VerifyOptions{ DNSName: "", Roots: Roots, } _, err := cert.Verify(opts) if err != nil { return err } return nil } ===== Client ===== tlsConfig := tls.Config{} tlsConfig.InsecureSkipVerify = true tlsConfig.Certificates = []tls.Certificate{func() tls.Certificate { CertKey, err := tls.X509KeyPair(ClientCert, ClientKey) if err != nil { panic(err) } return CertKey }()} tlsConfig.ClientAuth = tls.RequireAndVerifyClientCert tlsConfig.VerifyPeerCertificate = func(rawCerts [][]byte, verifiedChains [][]*x509.Certificate) error { Roots := x509.NewCertPool() Roots.AppendCertsFromPEM(CA) cert, _ := x509.ParseCertificate(rawCerts[0]) opts := x509.VerifyOptions{ DNSName: "", Roots: Roots, } _, err := cert.Verify(opts) if err != nil { return err } return nil }
