android 訪問https 證書問題 報錯javax.net.ssl.SSLHandshakeException

服務器url 切換爲https後所有接口調用報錯javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

解決辦法：

Android項目中使用 retrofit + rxjava +mvvp 架構

故在RetrofitConfig.java 的配置文件中  初始化

initOkhttp(){}

方法中加入以下代碼

OkHttpClient.Builder builder = new OkHttpClient.Builder();

int[] certificates = {R.raw.new_dd};
String hosts[]= {"*.diandianwaimai.com"};
//builder.sslSocketFactory(SslContextFactory.getSSLSocketFactory(DDApplication.getInstance().getContext(),   certificates));
//builder.hostnameVerifier(SslContextFactory.getHostnameVerifier(hosts));

try {
   CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
   KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
   keyStore.load(null);
   String certificateAlias = Integer.toString(0);
   keyStore.setCertificateEntry(certificateAlias, certificateFactory.
         generateCertificate(DDApplication.getInstance().getContext().getResources().openRawResource(R.raw.new_dd)));
   SSLContext sslContext = SSLContext.getInstance("TLS");
   final TrustManagerFactory trustManagerFactory =
         TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
   trustManagerFactory.init(keyStore);
   sslContext.init
         (
               null,
               trustManagerFactory.getTrustManagers(),
               new SecureRandom()
         );
   builder.sslSocketFactory(sslContext.getSocketFactory());
   builder.hostnameVerifier(new HostnameVerifier() {
      @Override
      public boolean verify(String s, SSLSession sslSession) {
         return true;
      }
   });
} catch (CertificateException e) {
   e.printStackTrace();
} catch (KeyStoreException e) {
   e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
   e.printStackTrace();
} catch (IOException e) {
   e.printStackTrace();
} catch (KeyManagementException e) {
   e.printStackTrace();
} catch (Exception ex) {

}

其中 new_dd 文件是在raw目錄下

生成.cer文件的方式給出鏈接自己去看，我就不重複了
