在golang中获取远程ssl证书 [英] Get remote ssl certificate in golang

问题描述

我想通过TLS接收TCP连接。我想验证客户端证书并使用它来向我的应用程序验证客户端。
Go有标准的 crypto / tls 包。它可以验证客户端/服务器证书。但我无法找到获取远程（客户端）证书详细信息的方法，例如通用名称。

I want to receive a TCP connection over TLS. I want to validate client certificate and use it to authenticate the client to my application. Go has the standard crypto/tls package. It can validate client/server certificates. But I can't find way to get details of the remote (client) certificate, like the common name.

推荐答案

必须请致电 crypto / tls / Conn.Handshake 。
然后你可以读对等证书：
tlsconn.ConnectionState（）。PeerCertificates [0] .Subject.CommonName

Have to call crypto/tls/Conn.Handshake. Then you can read peer certificate: tlsconn.ConnectionState().PeerCertificates[0].Subject.CommonName
