Class HttpsURLConnection


java.lang.Object
  extended by java.net.URLConnection
      extended by java.net.HttpURLConnection
          extended by javax.net.ssl.HttpsURLConnection

public abstract class HttpsURLConnection
extends HttpURLConnection

HttpsURLConnection extends HttpURLConnection with support for https-specific features.

See http://www.w3.org/pub/WWW/Protocols/ and RFC 2818 for more details on the https specification.

This class uses HostnameVerifier and SSLSocketFactory. There are default implementations defined for both classes. However, the implementations can be replaced on a per-class (static) or per-instance basis. All new HttpsURLConnections instances will be assigned the "default" static values at instance creation, but they can be overriden by calling the appropriate per-instance set method(s) before connecting.

Field Detail

hostnameVerifier


protected HostnameVerifier hostnameVerifier
The hostnameVerifier for this object.

Constructor Detail

HttpsURLConnection


protected HttpsURLConnection(URL url)
                      throws IOException
Creates an HttpsURLConnection using the URL specified.

Parameters:
url - the URL
Throws:
IOException - if the connection can't be established
Method Detail

getCipherSuite


public abstract String getCipherSuite()
Returns the cipher suite in use on this connection.

Returns:
the cipher suite
Throws:
IllegalStateException - if this method is called before the connection has been established.

getLocalCertificates


public abstract Certificate[] getLocalCertificates()
Returns the certificate(s) that were sent to the server during handshaking. Note: This method is useful only when using certificate-based cipher suites.

When multiple certificates are available for use in a handshake, the implementation chooses what it considers the "best" certificate chain available, and transmits that to the other side. This method allows the caller to know which certificate chain was actually sent.

Returns:
an ordered array of certificates, with the client's own certificate first followed by any certificate authorities. If no certificates were sent, then null is returned.
Throws:
IllegalStateException - if this method is called before the connection has been established.
See Also:
getLocalPrincipal()

getServerCertificates


public abstract Certificate[] getServerCertificates()
                                             throws SSLPeerUnverifiedException
Returns the server's certificate chain which was established as part of defining the session. Note: This method can be used only when using certificate-based cipher suites; using it with non-certificate-based cipher suites, such as Kerberos, will throw an SSLPeerUnverifiedException.

Returns:
an ordered array of server certificates, with the peer's own certificate first followed by any certificate authorities.
Throws:
SSLPeerUnverifiedException - if the peer is not verified.
IllegalStateException - if this method is called before the connection has been established.
See Also:
getPeerPrincipal()

getPeerPrincipal


 
public PrincipalgetPeerPrincipal ()
 throws SSLPeerUnverifiedException
Returns the server's principal which was established as part of defining the session. Note: Subclasses should override this method. If not overridden, it will default to returning the X500Principal of the server's end-entity certificate for certificate-based ciphersuites, or throw an SSLPeerUnverifiedException for non-certificate based ciphersuites, such as Kerberos.

Returns:
the server's principal. Returns an X500Principal of the end-entity certiticate for X509-based cipher suites, and KerberosPrincipal for Kerberos cipher suites.
Throws:
SSLPeerUnverifiedException - if the peer was not verified
IllegalStateException - if this method is called before the connection has been established.
Since:
1.5
See Also:
getServerCertificates() , getLocalPrincipal()

getLocalPrincipal


 
public PrincipalgetLocalPrincipal () 
Returns the principal that was sent to the server during handshaking. Note: Subclasses should override this method. If not overridden, it will default to returning the X500Principal of the end-entity certificate that was sent to the server for certificate-based ciphersuites or, return null for non-certificate based ciphersuites, such as Kerberos.

Returns:
the principal sent to the server. Returns an X500Principal of the end-entity certificate for X509-based cipher suites, and KerberosPrincipal for Kerberos cipher suites. If no principal was sent, then null is returned.
Throws:
IllegalStateException - if this method is called before the connection has been established.
Since:
1.5

getLocalCertificates() , getPeerPrincipal()

setDefaultHostnameVerifier


public static void setDefaultHostnameVerifier(HostnameVerifier v)
Sets the default HostnameVerifier inherited when an instance of this class is created.

If this method is not called, the default hostname verifier assumes the connection should not be permitted.

Parameters:
v - the default host name verifier
Throws:
IllegalArgumentException - if the HostnameVerifier parameter is null.
See Also:
getDefaultHostnameVerifier()

getDefaultHostnameVerifier


public static HostnameVerifier getDefaultHostnameVerifier()
Gets the default HostnameVerifier that it inherited when an instance of this class is created.

Returns:
the default host name verifier
See Also:
setDefaultHostnameVerifier(HostnameVerifier)

setHostnameVerifier


public void setHostnameVerifier(HostnameVerifier v)
Sets the HostnameVerifier.

When called on a new instance of this class, this method overrides the default static hostname verifier set by setDefaultHostnameVerifier .

Parameters:
v - the host name verifier
Throws:
IllegalArgumentException - if the HostnameVerifier parameter is null.
See Also:
getHostnameVerifier() , setDefaultHostnameVerifier(HostnameVerifier)

getHostnameVerifier


public HostnameVerifier getHostnameVerifier()
Gets the HostnameVerifier in place on this instance.

Returns:
the host name verifier
See Also:
setHostnameVerifier(HostnameVerifier) , setDefaultHostnameVerifier(HostnameVerifier)

the default SSLSocketFactory
See Also:
setDefaultSSLSocketFactory(SSLSocketFactory)

setSSLSocketFactory


public void setSSLSocketFactory(SSLSocketFactory sf)
Sets the SSL socket factory to be used when creating sockets for secure https URL connections.

If called on a new instance of this class, this method overrides the default static socket factory set by setDefaultSSLSocketFactory .
