Android - 如何使用HttpClient接受任何证书并同时传递证书

标签: java android ssl certificate httpclient

我有一个场景,我必须将证书传递给我的服务器,然后服务器向我发送他的证书,我必须接受它才能访问服务器。我正在使用HttpURLConnection,没有任何问题。

但是,我最近遇到了HttpURLConnection问题。我使用的代码从HTTPS服务器检索图像。如果图像很小(<500kb),则不会出现任何问题。然而,有了更大的图像,我得到了这个:

javax.net.ssl.SSLProtocolException:读取错误:ssl = 0x3c97e8:SSL库失败,通常是协议错误

我正在互联网上阅读它,很多人说使用HttpClient而不是HttpURLConnection是可行的方法(例如这个网站http://soan.tistory.com/62,认为是用韩文写的,我不能读它,但这就是我认为的。)

这是我的旧代码,使用URLConnection:

    public static URLConnection CreateFromP12(String uri, String keyFilePath,
        String keyPass, TrustManager[] trustPolicy, HostnameVerifier hv) {
    try {

        SSLContext sslContext = SSLContext.getInstance("TLS");
        KeyStore keyStore = KeyStore.getInstance("PKCS12");
        KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");

        keyStore.load(new FileInputStream(keyFilePath),
                keyPass.toCharArray());

        kmf.init(keyStore, keyPass.toCharArray());
        sslContext.init(kmf.getKeyManagers(), trustPolicy, null);

        HttpsURLConnection.setDefaultSSLSocketFactory(sslContext
                .getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch (Exception ex) {
        return null;
    }

    URL url;
    URLConnection conn;
    try {
        url = new URL(uri);
        conn = url.openConnection();
    } catch (MalformedURLException e) {
        return null;
    } catch (IOException e) {
        return null;
    }

    return conn;
}

这是新的,使用HttpClient:

public class HttpC2Connection {

public static HttpEntity CreateHttpEntityFromP12(String uri,
        String keyFilePath, String keyPass) throws Exception {

    KeyStore keyStore = KeyStore.getInstance("PKCS12");
    keyStore.load(new FileInputStream(keyFilePath), keyPass.toCharArray());

    SSLSocketFactory sf = new MySSLSocketFactory(keyStore);
    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("https", sf, 443));

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params,
            registry);

    HttpClient httpclient = new DefaultHttpClient(ccm, params);
    HttpGet httpget = new HttpGet(uri);
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();

    return entity;
}

但是现在,使用HttpClient,我的服务器返回一个错误,说我必须通过证书,所以我猜那个

SSLSocketFactory sf = new MySSLSocketFactory(keyStore); 

未加载我的证书。

那么,我怎样才能同时做以下两件事:

1。)将证书传递给我的服务器; 2.)接受来自我服务器的任何证书

使用HttpClient类?

以下代码禁用HttpsUrlConnection的任何新实例的SSL证书检查:

https://gist.github.com/aembleton/889392

/**
 * Disables the SSL certificate checking for new instances of {@link HttpsURLConnection} This has been created to
 * aid testing on a local box, not for use on production.
 */
private static void disableSSLCertificateChecking() {
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        @Override
        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }

        @Override
        public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }
    } };

    try {
        SSLContext sc = SSLContext.getInstance("TLS");

        sc.init(null, trustAllCerts, new java.security.SecureRandom());

        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

不要只接受任何证书。 不要使用破坏安全性的自制SSLSocketFactory。使用SDK中的SSLSocketFactory,并传递信任存储(包含服务器证书或颁发它的CA证书)和密钥库(包含客户端证书和私钥)。您可以使用this构造函数来实现此目的,JavaDoc详细介绍了如何创建密钥库。
