HttpsURLConnection

public abstract class HttpsURLConnection
extends HttpURLConnection

java.lang.Object
↳	java.net.URLConnection
	↳	java.net.HttpURLConnection
		↳	javax.net.ssl.HttpsURLConnection

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.

See also:

getLocalCertificates

Added in API level 1

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
`Certificate[]`	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()

getLocalPrincipal

Added in API level 1

Principal getLocalPrincipal ()

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
`Principal`	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.

See also:

getPeerPrincipal

Added in API level 1

Principal getPeerPrincipal ()

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
`Principal`	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.

See also:

getSSLSocketFactory

Added in API level 1

SSLSocketFactory getSSLSocketFactory ()

See also:

setSSLSocketFactory(SSLSocketFactory)

getServerCertificates

Added in API level 1

Certificate[] getServerCertificates ()

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
`Certificate[]`	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.

setHostnameVerifier

Added in API level 1

void setHostnameVerifier (HostnameVerifier v)

Sets the HostnameVerifier for this instance.

New instances of this class inherit the default static hostname verifier set by setDefaultHostnameVerifier. Calls to this method replace this object's HostnameVerifier.
