saml metadata 如何使用？

[botaruibo]

请教下，我现在活得对方的，samlmetadata文件。类似如下，怎么用它生成BasicX509Credential对象？： <EntityDescriptor xmlns="urn:oasis:names:tc:SAML:2.0:metadata" entityID="https://pmsal2demo8.successfactors.com/sf/idp/SAML2/company/SFPART048er3"> <IDPSSODescriptor WantAuthnRequestsSigned="false" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol"> <KeyDescriptor use="signing"> <ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> ds:X509Data ds:X509Certificate MIICDTCCAXagAwIBAgIETJj9LjANBgkqhkiG9w0BAQUFADBLMQswCQYDVQQGEwJVUzEbMBkGA1UE ChMSU3VjY2Vzc2ZhY3RvcnMuY29tMQwwCgYDVQQLEwNPcHMxETAPBgNVBAMTCFNGIEFkbWluMB4X DTEwMDkyMTE4NDUwMloXDTI1MDkxOTE4NDUwMlowSzELMAkGA1UEBhMCVVMxGzAZBgNVBAoTElN1 Y2Nlc3NmYWN0b3JzLmNvbTEMMAoGA1UECxMDT3BzMREwDwYDVQQDEwhTRiBBZG1pbjCBnzANBgkq hkiG9w0BAQEFAAOBjQAwgYkCgYEArA9RLNnL9Pt6xynFfYfa8VXAXFDG9Y8xkgs3lhIOlsjqEYwb SoghiqJIJvfYM45kx3aB7ZrN96tAR5uUupEsu/GcS6ACxhfruW+BY6uw8v6/w2vXhBdfFjBoO+Ke Lx4k3llleVgKsmNlf81okOXv1ree8wErfZ3ssnNxkuQgGB0CAwEAATANBgkqhkiG9w0BAQUFAAOB gQBeBCSMFnY8TB6jtWoSP/lorBudhptgvO7/3r+l/QK0hdk6CVv+VQmSilNPgWVgU9ktZGbNkZhw IgwnqIQHAi6631ufkYQJB+48YUe1q/pv6EWaeIwGvcGYSXZp/E/aGZPtceTIXFPfqOyHQoFtb0nq MMFWoDhpXUHmlroyTc9sJg== </ds:X509Certificate> </ds:X509Data> </ds:KeyInfo> </KeyDescriptor> <SingleSignOnService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://pmsalesdemo8.successfactors.com/sf/idp/SAML2/SSO/POST/company/SFPART048243"/> <SingleSignOnService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" Location="https://pmsalesdemo8.successfactors.com/sf/idp/SAML2/SSO/Redirect/company/SFPART048243"/> <SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://pmsalesdemo8.successfactors.com/sf/idp/SAML2/slo/POST"/> <NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</NameIDFormat> <NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified</NameIDFormat> </IDPSSODescriptor> </EntityDescriptor>
