本文介绍如何使用Volley库在Android应用中配置HTTPS连接，包括信任所有证书及指定证书的方法。通过自定义TrustManager和SSLContext，可以实现对不同HTTPS证书的信任处理。

Volley之https信任所有证书实现：

public class HttpsTrustManager implements X509TrustManager {

    private static TrustManager[] trustManagers;
    private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

    @Override
    public void checkClientTrusted(
            java.security.cert.X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    @Override
    public void checkServerTrusted(
            java.security.cert.X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return true;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return _AcceptedIssuers;
    }

    public static void allowAllSSL() {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }

        });

        SSLContext context = null;
        if (trustManagers == null) {
            trustManagers = new TrustManager[]{new HttpsTrustManager()};
        }

        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }

        HttpsURLConnection.setDefaultSSLSocketFactory(context
                .getSocketFactory());
    }

}

代码中调用方法如下：

HttpsTrustManager.allowAllSSL();//主要是这行实现信任所有证书的操作
String  tag_string_req = "string_req";
StringRequest strReq = new StringRequest(Request.Method.POST,
        your_https_url, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        Log.d(TAG, "response :"+response);
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.d(TAG, "Error: " + error.getMessage());
    }
}){
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
        params.put("username", "max");
        params.put("password", "123456");
        return params;
    }
};
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);

信任指定的证书文件：

HurlStack代码里面有如下方法：

 /**
     * @param urlRewriter Rewriter to use for request URLs
     * @param sslSocketFactory SSL factory to use for HTTPS connections
     * HurlStack这个类的构造大家就会发现其实volley可以支持https了，同样位于toolbox包下
     */
    public HurlStack(UrlRewriter urlRewriter, SSLSocketFactory sslSocketFactory) {
        mUrlRewriter = urlRewriter;
        mSslSocketFactory = sslSocketFactory;
    }

  /**
     * Opens an {@link HttpURLConnection} with parameters.
     * @param url
     * @return an open connection
     * @throws IOException
     */
    private HttpURLConnection openConnection(URL url, Request<?> request) throws IOException {
        HttpURLConnection connection = createConnection(url);

        int timeoutMs = request.getTimeoutMs();
        connection.setConnectTimeout(timeoutMs);
        connection.setReadTimeout(timeoutMs);
        connection.setUseCaches(false);
        connection.setDoInput(true);

        // use caller-provided custom SslSocketFactory, if any, for HTTPS
        if ("https".equals(url.getProtocol()) && mSslSocketFactory != null) {
            ((HttpsURLConnection)connection).setSSLSocketFactory(mSslSocketFactory);
        }

        return connection;
    }

在https协议的情况下，保证mSslSocketFactory 不为null,因此主要的问题是传进去sslSocketFactory这个参数。

stackoverflow上面有个产生这个内容的工具类：

private TrustManager[] getWrappedTrustManagers(TrustManager[] trustManagers) {
        final X509TrustManager originalTrustManager = (X509TrustManager) trustManagers[0];
        return new TrustManager[]{
                new X509TrustManager() {
                    public X509Certificate[] getAcceptedIssuers() {
                        return originalTrustManager.getAcceptedIssuers();
                    }

                    public void checkClientTrusted(X509Certificate[] certs, String authType) {
                        try {
                            originalTrustManager.checkClientTrusted(certs, authType);
                        } catch (CertificateException e) {
                            e.printStackTrace();
                        }
                    }

                    public void checkServerTrusted(X509Certificate[] certs, String authType) {
                        try {
                            originalTrustManager.checkServerTrusted(certs, authType);
                        } catch (CertificateException e) {
                            e.printStackTrace();
                        }
                    }
                }
        };
    }

private SSLSocketFactory getSSLSocketFactory_Certificate(String keyStoreType, int keystoreResId)
        throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException {

    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    InputStream caInput = getResources().openRawResource(keystoreResId);

    Certificate ca = cf.generateCertificate(caInput);
    caInput.close();

    if (keyStoreType == null || keyStoreType.length() == 0) {
        keyStoreType = KeyStore.getDefaultType();
    }
    KeyStore keyStore = KeyStore.getInstance(keyStoreType);
    keyStore.load(null, null);
    keyStore.setCertificateEntry("ca", ca);

    String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
    TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
    tmf.init(keyStore);

    TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());

    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, wrappedTrustManagers, null);

    return sslContext.getSocketFactory();
}

private SSLSocketFactory getSSLSocketFactory_KeyStore(String keyStoreType, int keystoreResId, String keyPassword)
            throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException {

        InputStream caInput = getResources().openRawResource(keystoreResId);

        // creating a KeyStore containing trusted CAs

        if (keyStoreType == null || keyStoreType.length() == 0) {
            keyStoreType = KeyStore.getDefaultType();
        }
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);

        keyStore.load(caInput, keyPassword.toCharArray());

        // creating a TrustManager that trusts the CAs in the KeyStore

        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);

        TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());

        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, wrappedTrustManagers, null);

        return sslContext.getSocketFactory();
    }

调用后面两个，就能获取SSLSocketFactory 内容，使用如下：

SSLSocketFactory sslSocketFactory = getSSLSocketFactory_KeyStore("BKS", R.raw.androidbksv1, "123456789");
SSLSocketFactory sslSocketFactory = getSSLSocketFactory_Certificate("BKS", R.raw.androidbksv1_cert);
