SAML 2.0安全單點登錄使用FilemetadataProvider

Question

我想知道我怎麼可以檢索使用Opensaml library.I下面的元數據文件中的斷言使用者網址已使用該庫，並通過代碼

得到了實體ID EntityDescriptor entityDescriptor =（EntityDescriptor）filesystemMetadataProvider.getMetadata（）; System.out.print（entityDescriptor.getEntityID（））;

現在我需要從元數據文件得到一個斷言消費者網址你可以請任何人建議我一個代碼片段來檢索這個。

這裏是我的元數據文件

Answer 1

for (AssertionConsumerService acs : entityDescriptor.getIDPSSODescriptor(SAMLConstants.SAML20P_NS) 
     .getAssertionConsumerServices()) { 
     assertionConsumerServiceURL = ars.getLocation(); 
}
