类名称：X509Certificate
方法名：getBasicConstraints

X509Certificate.getBasicConstraints介绍

[英]Returns the path length of the certificate constraints from the BasicContraints extension. If the certificate has no basic constraints or is not a certificate authority, -1 is returned. If the certificate is a certificate authority without a path length, Integer.MAX_VALUE is returned. Otherwise, the certificate authority's path length is returned.
[中]返回BasicContaints扩展中证书约束的路径长度。如果证书没有基本约束或不是证书颁发机构，则返回-1。如果证书是没有路径长度的证书颁发机构，则为整数。返回最大值。否则，将返回证书颁发机构的路径长度。
