我有一个奇怪的问题。看起来 OpenSSL 的“s_client”工具不喜欢我的 AppEngine 应用程序的 SSL 证书，甚至不承认它（“没有可用的对等证书”），但是 Python 的 SSL 模块报告了颁发者、日期范围、序列号、主题等等，好像完全没有问题一样。
我假设我的 SSL 证书存在一些细微的错误配置，但是，由于 AppEngine 提供了一个非常简单的上传证书向导，说配置错误就是说谷歌的功能被破坏了......我怀疑这是案子。
如果其他人经历过，我很想对此有所了解。
s_client：
openssl s_client -connect www.abc.com:443
s_client 输出：
CONNECTED(00000003)
