我已经尝试了两天，但是我仍然无法让它正常工作。
我拥有一个真实的证书，由COMODO签名，而COMODO本身则是由USERTrust签名。但是当我尝试连接到我的域时，就会出现以下情况：
javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
我正在使用的代码是：
public void postData() {
// Add your data
try {
HttpPost post = new HttpPost(new URI("https://example.com"));
KeyStore trusted = KeyStore.getInstance("BKS");
trusted.load(null, "".toCharArray());
SSLSocketFactory sslf = new SSLSocketFactory(trusted);
sslf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme ("https", sslf, 443));
SingleClientConnManager cm = new SingleClientConnManager(post.getParams(),
schemeRegistry);
HttpClient client = new DefaultHttpClient(cm, post.getParams());
// Execute HTTP Post Request
@SuppressWarnings("unused")
HttpResponse result = client.execute(post);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (KeyStoreException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (CertificateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.e(TAG,e.toString());
Log.e(TAG,e.getMessage());
} catch (KeyManagementException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
} catch (UnrecoverableKeyException e) {
// TODO Auto-generated catch block
Log.e(TAG,e.getMessage());
Log.e(TAG,e.toString());
e.printStackTrace();
}
}
我尝试了我的域名以及https://google.com，它们都返回相同的结果。以下是堆栈信息：

此外，在查看日志时，我发现可能导致此问题的错误：
02-01 10:44:13.122: W/System.err(15746): Catch exception while startHandshake: javax.net.ssl.SSLHandshakeException: java.security.InvalidAlgorithmParameterException: trustAnchors.isEmpty()
02-01 10:44:13.122: W/System.err(15746): return an invalid session with invalid cipher suite of SSL_NULL_WITH_NULL_NULL
在过去的两天里，我读了许多文章，解释如何连接到一个自签名SSL保护的网站。我还发现了这个问题，我从中获取了代码，但我无法想象“使用默认的Android验证机制”是什么意思以及如何实施它。
有人能提供一段代码来修复或实现连接到真正的证书吗？
谢谢！
