此电子邮件末尾列出的您的应用使用不安全的应用 接口X509TrustManager的实现。具体来说, 实现时忽略所有SSL证书验证错误 建立与远程主机的HTTPS连接,从而使您的 应用程序容易受到中间人攻击。
要正确处理SSL证书验证,请更改您的代码 自定义X509TrustManager接口的checkServerTrusted方法 无论何时提出CertificateException或IllegalArgumentException 服务器提供的证书不符合您的要求 期望。
在查看代码时我发现没有这样的方法(checkServerTrusted - X509TrustManager)。只有X509EncodedKeySpec用于应用内结算。
