Android 实现 HttpClient 请求Https

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
