Android 使用 HTTPS 配置的步骤。

1、step

配置hostnameVerifier

 new HostnameVerifier() {
   @Override
    public boolean verify(String hostname, SSLSession session) {
     return true;
    }
 }；

2.step

配置 sslSocketFactory

public static SSLSocketFactory getSslSocketFactory(InputStream[] certificates, InputStream bksFile, String password){
  try{
   TrustManager[] trustManagers = prepareTrustManager(certificates);
   KeyManager[] keyManagers = prepareKeyManager(bksFile, password);
   SSLContext sslContext = SSLContext.getInstance("TLS");
   TrustManager trustManager = null;
   if (trustManagers != null){
    trustManager = new MyTrustManager(chooseTrustManager(trustManagers));
   } else{
    trustManager = new UnSafeTrustManager();
   }
   sslContext.init(keyManagers, new TrustManager[]{trustManager}, new SecureRandom());
   return sslContext.getSocketFactory();
  } catch (NoSuchAlgorithmException e){
   throw new AssertionError(e);
  } catch (KeyManagementException e){
   throw new AssertionError(e);
  } catch (KeyStoreException e){
   throw new AssertionError(e);
  }
 }

 private class UnSafeHostnameVerifier implements HostnameVerifier{
  @Override
  public boolean verify(String hostname, SSLSession session){
   return true;
  }
 }

 private static class UnSafeTrustManager implements X509TrustManager{
  @Override
  public void checkClientTrusted(X509Certificate[] chain, String authType)throws CertificateException{}

  @Override
  public void checkServerTrusted(X509Certificate[] chain, String authType)throws CertificateException{}

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

 private static TrustManager[] prepareTrustManager(InputStream... certificates){
  if (certificates == null || certificates.length <= 0) return null;
  try{
   CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
   KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
   keyStore.load(null);
   int index = 0;
   for (InputStream certificate : certificates){
    String certificateAlias = Integer.toString(index++);
    keyStore.setCertificateEntry(certificateAlias, certificateFactory.generateCertificate(certificate));
    try{
     if (certificate != null)
      certificate.close();
    } catch (IOException e){
    }
   }
   TrustManagerFactory trustManagerFactory = null;
   trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
   trustManagerFactory.init(keyStore);
   TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
   return trustManagers;
  } catch (NoSuchAlgorithmException e){
   e.printStackTrace();
  } catch (CertificateException e){
   e.printStackTrace();
  } catch (KeyStoreException e){
   e.printStackTrace();
  } catch (Exception e){
   e.printStackTrace();
  }
  return null;

 }

 private static KeyManager[] prepareKeyManager(InputStream bksFile, String password){
  try{
   if (bksFile == null || password == null) return null;
   KeyStore clientKeyStore = KeyStore.getInstance("BKS");
   clientKeyStore.load(bksFile, password.toCharArray());
   KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
   keyManagerFactory.init(clientKeyStore, password.toCharArray());
   return keyManagerFactory.getKeyManagers();
  } catch (KeyStoreException e){
   e.printStackTrace();
  } catch (NoSuchAlgorithmException e){
   e.printStackTrace();
  } catch (UnrecoverableKeyException e){
   e.printStackTrace();
  } catch (CertificateException e){
   e.printStackTrace();
  } catch (IOException e){
   e.printStackTrace();
  } catch (Exception e){
   e.printStackTrace();
  }
  return null;
 }

 private static X509TrustManager chooseTrustManager(TrustManager[] trustManagers){
  for (TrustManager trustManager : trustManagers){
   if (trustManager instanceof X509TrustManager){
    return (X509TrustManager) trustManager;
   }
  }
  return null;
 }

 private static class MyTrustManager implements X509TrustManager{
  private X509TrustManager defaultTrustManager;
  private X509TrustManager localTrustManager;

  public MyTrustManager(X509TrustManager localTrustManager) throws NoSuchAlgorithmException, KeyStoreException{
   TrustManagerFactory var4 = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
   var4.init((KeyStore) null);
   defaultTrustManager = chooseTrustManager(var4.getTrustManagers());
   this.localTrustManager = localTrustManager;
  }

  @Override
  public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException{}

  @Override
  public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException{
   try{
    defaultTrustManager.checkServerTrusted(chain, authType);
   } catch (CertificateException ce){
    localTrustManager.checkServerTrusted(chain, authType);
   }
  }

  @Override
  public X509Certificate[] getAcceptedIssuers(){
   return new X509Certificate[0];
  }
 }

调用 getSslSocketFactory(null,null,null) 即可。

3.step

设置OkhttpClient。

HTTPS配置如何在Android项目中使用

方法 getSslSocketFactory(null,null,null) 的第一个参数 本来要传入自签名证书的，当传入null 即可忽略自签名证书。

如果你想尝试不忽略自签名证书 你可以调用下面的方法获取 SSLSocketFactory。并设置到OkhttpClient中。

 public static SSLSocketFactory getSSlFactory(Context context) {

  try {
   CertificateFactory cf = CertificateFactory.getInstance("X.509");
   InputStream caInput = new BufferedInputStream(context.getAssets().open("client.cer"));//把证书打包在asset文件夹中
   Certificate ca;
   try {
    ca = cf.generateCertificate(caInput);
    LogUtil.d("Longer", "ca=" + ((X509Certificate) ca).getSubjectDN());
    LogUtil.d("Longer", "key=" + ((X509Certificate) ca).getPublicKey());
   } finally {
    caInput.close();
   }

   // Create a KeyStore containing our trusted CAs
   String keyStoreType = KeyStore.getDefaultType();
   KeyStore keyStore = KeyStore.getInstance(keyStoreType);
   keyStore.load(null, null);
   keyStore.setCertificateEntry("ca", ca);

   // Create a TrustManager that trusts the CAs in our KeyStore
   String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
   TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
   tmf.init(keyStore);

   // Create an SSLContext that uses our TrustManager
   SSLContext s = SSLContext.getInstance("TLSv1", "AndroidOpenSSL");
   s.init(null, tmf.getTrustManagers(), null);

   return s.getSocketFactory();
  } catch (CertificateException e) {
   e.printStackTrace();
  } catch (IOException e) {
   e.printStackTrace();
  } catch (NoSuchAlgorithmException e) {
   e.printStackTrace();
  } catch (KeyStoreException e) {
   e.printStackTrace();
  } catch (KeyManagementException e) {
   e.printStackTrace();
  } catch (NoSuchProviderException e) {
   e.printStackTrace();
  }
  return null;
 }

通过上面的几步配置即可使用https的自签名证书 和 单向验证的Https了。

Glide 访问Https的图片

1.step

在build.gradle 引入下面的aar

/提供的Module/
compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'

2.step

 OkHttpClient okhttpClient = new OkHttpClient.Builder()
    .connectTimeout(30, TimeUnit.SECONDS)
    .retryOnConnectionFailure(true) //设置出现错误进行重新连接。
    .connectTimeout(15, TimeUnit.SECONDS)
    .readTimeout(60 * 1000, TimeUnit.MILLISECONDS)
    .sslSocketFactory(HttpsUtils.getSslSocketFactory(null,null,null))
    .hostnameVerifier(new HostnameVerifier() {
     @Override
     public boolean verify(String hostname, SSLSession session) {
      return true;
     }
    })
     .build();
  //让Glide能用HTTPS
  Glide.get(this).register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(okhttpClient));

设置已经验证证书的的OkhttpClient 到Glide 既可。
