太可惜了，没人回答。我能够做到，首先编写一个 ，然后执行以下操作：
String scheme = "https";
Protocol baseHttps = Protocol.getProtocol(scheme);
int defaultPort = baseHttps.getDefaultPort();
ProtocolSocketFactory baseFactory = baseHttps.getSocketFactory();
ProtocolSocketFactory customFactory = new CustomHttpsSocketFactory(baseFactory);
Protocol customHttps = new Protocol(scheme, customFactory, defaultPort);
Protocol.registerProtocol(scheme, customHttps);
public class CustomHttpsSocketFactory implements SecureProtocolSocketFactory
{
private final SecureProtocolSocketFactory base;
public CustomHttpsSocketFactory(ProtocolSocketFactory base)
{
if(base == null || !(base instanceof SecureProtocolSocketFactory)) throw new IllegalArgumentException();
this.base = (SecureProtocolSocketFactory) base;
}
private Socket acceptOnlyTLS12(Socket socket)
{
if(!(socket instanceof SSLSocket)) return socket;
SSLSocket sslSocket = (SSLSocket) socket;
sslSocket.setEnabledProtocols(new String[]{"TLSv1.2" });
return sslSocket;
}
@Override
public Socket createSocket(String host, int port) throws IOException
{
return acceptOnlyTLS12(base.createSocket(host, port));
}
@Override
public Socket createSocket(String host, int port, InetAddress localAddress, int localPort) throws IOException
{
return acceptOnlyTLS12(base.createSocket(host, port, localAddress, localPort));
}
@Override
public Socket createSocket(String host, int port, InetAddress localAddress, int localPort, httpconnectionParams params) throws IOException
{
return acceptOnlyTLS12(base.createSocket(host, port, localAddress, localPort, params));
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException
{
return acceptOnlyTLS12(base.createSocket(socket, host, port, autoClose));
}
}
