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();       
        }       
    }
