SSL/TLS的定制

HttpClient使用SSLSocketFactory来创建SSL连接。SSLSocketFactory允许高度定制。它可以使用javax.net.ssl.SSLContext的实例作为参数，并使用它来创建定制SSL连接。

TrustManager easyTrustManager = new X509TrustManager() {

@Override

public void checkClientTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

// 哦，这很简单！

}

@Override

public void checkServerTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

//哦，这很简单！

}

@Override

public X509Certificate[] getAcceptedIssuers() {

return null;

}

};

SSLContext sslcontext = SSLContext.getInstance("TLS");

sslcontext.init(null, new TrustManager[] { easyTrustManager }, null);

SSLSocketFactory sf = new SSLSocketFactory(sslcontext);

SSLSocket socket = (SSLSocket) sf.createSocket();

socket.setEnabledCipherSuites(new String[] { "SSL_RSA_WITH_RC4_128_MD5" });

HttpParams params = new BasicHttpParams();

params.setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 1000L);

sf.connectSocket(socket, "locahost", 443, null, -1, params);

SSLSocketFactory的定制暗示出一定程度SSL/TLS协议概念的熟悉，这个详细的解释超出了本文档的范围。请参考Java的安全套接字扩展[http://java.sun.com/j2se/1.5.0/docs/guide/

security/jsse/JSSERefGuide.html]，这是javax.net.ssl.SSLContext和相关工具的详细描述
