據說這兩天騰訊的服務器出了問題，認證的時候報這樣的錯：

oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Not trusted server certificate Caused by: javax.net.ssl.SSLPeerUnverifiedException: No peer certificate

oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Nopeer certificate?
這是因為Https認證被截獲導致，Client認為安全失效，很久之前就出現了這個問題了，那時候在WebView上加上下面的代碼就可以解決了

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { handler.proceed(); }

沒想到又出現這個問題，于是一翻研究，在stackoverflow.com上找到答案，寫了一個自定義類繼承SSLSocketFactory

public class SSLSocketFactoryEx extends SSLSocketFactory { SSLContext sslContext = SSLContext.getInstance("TLS"); public SSLSocketFactoryEx(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException { super(truststore); TrustManager tm = new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } @Override public void checkClientTrusted( java.security.cert.X509Certificate[] chain, String authType) throws java.security.cert.CertificateException { } @Override public void checkServerTrusted( java.security.cert.X509Certificate[] chain, String authType) throws java.security.cert.CertificateException {} }; sslContext.init(null, new TrustManager[] { tm }, null); } @Override public Socket createSocket(Socket socket, String host, int port,boolean autoClose) throws IOException, UnknownHostException { return sslContext.getSocketFactory().createSocket(socket, host, port,autoClose); } @Override public Socket createSocket() throws IOException { return sslContext.getSocketFactory().createSocket(); } } 調用方法，只要用認證返回的HttpCilent即可。代碼： Java 代碼復制內容到剪貼板public HttpClient getNewHttpClient() { try { KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); trustStore.load(null, null); SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore); 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("http", PlainSocketFactory.getSocketFactory(), 80)); registry.register(new Scheme("https", sf, 443)); ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry); return new DefaultHttpClient(ccm, params); } catch (Exception e) { return new DefaultHttpClient(); } }

這樣就解決了問題，有網友說把騰訊認證的地址https去掉改成http，那是不可取的做法。

我已經把代碼集成到signpost中，如果有需要的同學可自行下載，有不明白或者不好的地方給我評論留言。
