Issuer public key can only be obtained from issuer cert and this is not present in leaf cert(received cert)(thanks bartonjs) The solution I have is to build full chain get reach to the signer to get the key or have the issuer certificate obtained from another source (if possible).颁发者公钥只能从颁发者证书中获得，这在叶子证书中不存在（已收到证书）（感谢 bartonjs）我的解决方案是建立完整的链来联系签名者以获取密钥或获得颁发者证书从另一个来源（如果可能）。 In my case, I have another source so I am able to get it.就我而言，我有另一个来源，所以我可以得到它。 thanks for the guidance.感谢您的指导。
