Android 实现 HttpClient 请求Https，默认情况下，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。
