http请求No peer certificate的解决方法

不少同学在做HTTP请求新浪授权或新浪数据的时候会出现 javax.net.ssl.SSLPeerUnverifiedException: No peer certificate的异常。现给出解决方法（已通过测试）。

写了一个自定义类继承SSLSocketFactory：

1. import java.io.IOException;
2. import java.net.Socket;
3. import java.net.UnknownHostException;
4. import java.security.KeyManagementException;
5. import java.security.KeyStore;
6. import java.security.KeyStoreException;
7. import java.security.NoSuchAlgorithmException;
8. import java.security.UnrecoverableKeyException;
9. import javax.net.ssl.SSLContext;
10. import javax.net.ssl.TrustManager;
11. import javax.net.ssl.X509TrustManager;
12. import org.apache.http.conn.ssl.SSLSocketFactory;
13. public class SSLSocketFactoryEx extends SSLSocketFactory {
14. SSLContext sslContext = SSLContext.getInstance("TLS");
15. public SSLSocketFactoryEx(KeyStore truststore)
16. throws NoSuchAlgorithmException, KeyManagementException,
17. KeyStoreException, UnrecoverableKeyException {
18. super(truststore);
19. TrustManager tm = new X509TrustManager() {
20. public java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}
21. @Override
22. public void checkClientTrusted(
23. java.security.cert.X509Certificate[] chain, String authType)
24. throws java.security.cert.CertificateException {}
25. @Override
26. public void checkServerTrusted(
27. java.security.cert.X509Certificate[] chain, String authType)
28. throws java.security.cert.CertificateException {}
29. };
30. sslContext.init(null, new TrustManager[] { tm }, null);
31. }
32. @Override
33. public Socket createSocket(Socket socket, String host, int
    port,boolean autoClose) throws IOException, UnknownHostException {
34. return sslContext.getSocketFactory().createSocket(socket, host, port,autoClose);
35. }
36. @Override
37. public Socket createSocket() throws IOException {
38. return sslContext.getSocketFactory().createSocket();
39. }
40. }

再来看看如何做回调：

1. public static HttpClient getNewHttpClient() {
2. try {
3. KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
4. trustStore.load(null, null);
5. SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);
6. sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
7. HttpParams params = new BasicHttpParams();
8. HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
9. HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
10. SchemeRegistry registry = new SchemeRegistry();
11. registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
12. registry.register(new Scheme("https", sf, 443));
13. ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
14. return new DefaultHttpClient(ccm, params);
15. } catch (Exception e) {
16. return new DefaultHttpClient();
17. }
18. }

现在就可以拿这个HTTPClient去请求数据了！！！！！GOOD
