获取XMPP S2S网关证书

Question

我正在尝试从XMPP s2s网关获取证书。我已经尝试过使用openssl，但是在公共XMPP服务器“ jabber.at”上变得像这样

    override func layoutSubviews() {
    super.layoutSubviews()
        self.layer.shadowPath = UIBezierPath(roundedRect: self.bounds,  cornerRadius: self.contentView.layer.cornerRadius).cgPath
    }

我是XMPP / Jabber的新手。还包括jabber.at的SRV记录。

$ openssl s_client -starttls xmpp-server  -connect xmpp.jabber.at:5269
CONNECTED(00000003)

Answer 1

您可能还需要指定-xmpphost hostname ，其中 hostname 是jabber ID中@后面的名称，例如

当您的XMPP服务器托管JID your_name@example.com时，主机名将为example.com。
