Android 實現 HttpClient 請求Https

Android 實現 HttpClient 請求Https，默認情況下，HttpClient是不能請求Https的，需要自己獲取。

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類

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();
}
}

通過上面的方法獲得HttpClient對象就可以請求Https了。
