HttpsURLConnection with IP issue - connection

Question

String currentUrl = "https://www.test.com/";
conn = (HttpsURLConnection) (currentUrl.openConnection())
If i use domain, everything works perfectly.
However, if i use the ip address of the domain,
String currentUrl = "https://123.123.123.123:443/";
conn = (HttpsURLConnection) (currentUrl.openConnection());
problem occurs, i got the SSLPeerUnverifiedException(Hostname 123.123.123.123 not verified Exception, and the request failed.
In order to fix this problem, i just provide a HostnameVerifier
conn.setHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
String host = "www.test.com";
return HttpsURLConnection.getDefaultHostnameVerifier().verify(host, session);
}
});
in addition, i have to solve the same problem of SNI situation.
so i provide a custom SSLSocketFactory
MySSLSocketFactory sslSocketFactory = new MySSLSocketFactory(conn);
conn.setSSLSocketFactory(sslSocketFactory);
public class MySSLSocketFactory extends SSLSocketFactory{
private HttpsURLConnection conn;
public HalleySSLSocketFactory(HttpsURLConnection conn) {
this.conn = conn;
}
#Override
public Socket createSocket() throws IOException {
return null;
}
#Override
public Socket createSocket(String host, int port) throws IOException,
UnknownHostException {
return null;
}
#Override
public Socket createSocket(String host, int port, InetAddress localHost,
int localPort) throws IOException, UnknownHostException {
return null;
}
#Override
public Socket createSocket(InetAddress host, int port) throws IOException {
return null;
}
#Override
public Socket createSocket(InetAddress address, int port,
InetAddress localAddress, int localPort) throws IOException {
return null;
}
#Override
public String[] getDefaultCipherSuites() {
return new String[0];
}
#Override
public String[] getSupportedCipherSuites() {
return new String[0];
}
#Override
public Socket createSocket(Socket plainSocket, String host, int port,
boolean autoClose) throws IOException {
String peerHost = this.conn.getRequestProperty("Host");
if (peerHost == null)
peerHost = host;
InetAddress address = plainSocket.getInetAddress();
if (autoClose) {
plainSocket.close();
}
SSLCertificateSocketFactory sslSocketFactory = (SSLCertificateSocketFactory) SSLCertificateSocketFactory
.getDefault(0);
SSLSocket ssl = (SSLSocket) sslSocketFactory
.createSocket(address, port);
ssl.setEnabledProtocols(ssl.getSupportedProtocols());
// set up SNI before the handshake
try {
java.lang.reflect.Method setHostnameMethod = ssl.getClass()
.getMethod("setHostname", String.class);
setHostnameMethod.invoke(ssl, peerHost);
} catch (Exception e) {
FileLog.w(TAG, "SNI not useable", e);
}
return ssl;
}
}
Unfortunately, it still has another problem,
it can't reuse the connection any more, which means every request have to tcp handshake and ssl handshake and it will cost a lot of time.
So Here is my question,
is there anyway to solve the direct IP request problem with HttpsUrlConnection?
if no, how can i reuse the connection according to what i mentioned above.

Answer 1

Try this:
conn.setHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
