如题，默认下，HttpClient是不能请求Https的，需要自己获取

private static final int SET_CONNECTION_TIMEOUT = 5 * 1000;

private static final int SET_SOCKET_TIMEOUT = 20 * 1000;

public static HttpClient getNewHttpClient() {

try {

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());

trustStore.load(null, null);

SSLSocketFactory sf = new MySSLSocketFactory(trustStore);

sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

HttpParams params = new BasicHttpParams();

HttpConnectionParams.setConnectionTimeout(params, 10000);

HttpConnectionParams.setSoTimeout(params, 10000);

HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);

HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

SchemeRegistry registry = new SchemeRegistry();

registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));

registry.register(new Scheme("https", sf, 443));

ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

HttpConnectionParams.setConnectionTimeout(params, SET_CONNECTION_TIMEOUT);

HttpConnectionParams.setSoTimeout(params, SET_SOCKET_TIMEOUT);

HttpClient client = new DefaultHttpClient(ccm, params);

return client;

} catch (Exception e) {

return new DefaultHttpClient();

}

}

下面是MySSLSocketFactory类

private static class MySSLSocketFactory extends SSLSocketFactory {

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

public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException,

KeyManagementException, KeyStoreException, UnrecoverableKeyException {

super(truststore);

TrustManager tm = new X509TrustManager() {

public void checkClientTrusted(X509Certificate[] chain, String authType)

throws CertificateException {

}

public void checkServerTrusted(X509Certificate[] chain, String authType)

throws CertificateException {

}

public X509Certificate[] getAcceptedIssuers() {

return null;

}

};

sslContext.init(null, new TrustManager[] { tm }, null);

}

@Override

public Socket createSocket(Socket socket, String host, int port, boolean autoClose)

throws IOException, UnknownHostException {

return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);

}

@Override

public Socket createSocket() throws IOException {

return sslContext.getSocketFactory().createSocket();

}

}

通过上面的方法获得HttpClient对象就可以请求Https了
