四大微博OAuth认证

据说这两天腾讯的服务器出了问题，认证的时候报这样的错：

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
这是因为Https认证被截获导致，Client认为安全失效，很久之前就出现了这个问题了，那时候在WebView上加上下面的代码就可以解决了

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

没想到又出现这个问题，于是一翻研究，在stackoverflow.com上找到答案，写了一个自定义类继承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(); } } 调用方法，只要用认证返回的HttpCilent即可。代码：Java 代码复制内容到剪贴板 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(); } }
