Android 4.4 - HttpClient - TLS - 接受所有证书

标签: android ssl

我正在开发一款应用。定位 Android 4.4(API级别19),我希望在HTTP交换期间,在HTTPS连接的情况下接受所有证书。这是一个明确的选择,因为我的应用程序类似于扫描仪。

我找到的所有示例都使用了类“ org.apache.http.conn.ssl.SSLSocketFactory ”拥有一个接受SSL上下文和主机名验证程序的构造函数的事实。

问题是API级别19中的“SSLSocketFactory”类的实现不再具有此构造函数版本,我找不到向类“SSLSocketFactory”提供自定义TrustManager的方法。

在Android API级别19中,仍然可以通过HttpClient实现我的目标吗?

信任SSL工厂:

public class TrustSSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public TrustSSLSocketFactory(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();
    }
}

用法:

KeyStore trustStore = KeyStore.getInstance(KeyStore
                    .getDefaultType());
            trustStore.load(null, null);
        SSLSocketFactory sf = new TrustSSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        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);

        return new DefaultHttpClient(ccm, params);

(这是我目前使用的代码。请注意,非常不安全,因此仅用于开发

我无法记住我从哪里获得此代码,所以我不能相信原作者。
