[Android实例] 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. 
   
10. import javax.net.ssl.SSLContext;
    
11. import javax.net.ssl.TrustManager;
    
12. import javax.net.ssl.X509TrustManager;
    
13. 
    
14. import org.apache.http.conn.ssl.SSLSocketFactory;
    
15. 
    
16. public class SSLSocketFactoryEx extends SSLSocketFactory {
    
17. 
    
18. SSLContext sslContext = SSLContext.getInstance("TLS");
    
19. 
    
20. public SSLSocketFactoryEx(KeyStore truststore)
    
21. throws NoSuchAlgorithmException, KeyManagementException,
    
22. KeyStoreException, UnrecoverableKeyException {
    
23. super(truststore);
    
24. 
    
25. TrustManager tm = new X509TrustManager() {
    
26. public java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}
    
27. 
    
28. @Override
    
29. public void checkClientTrusted(
    
30. java.security.cert.X509Certificate[] chain, String authType)
    
31. throws java.security.cert.CertificateException {}
    
32. 
    
33. @Override
    
34. public void checkServerTrusted(
    
35. java.security.cert.X509Certificate[] chain, String authType)
    
36. throws java.security.cert.CertificateException {}
    
37. };
    
38. sslContext.init(null, new TrustManager[] { tm }, null);
    
39. }
    
40. 
    
41. @Override
    
42. public Socket createSocket(Socket socket, String host, int port,boolean autoClose) throws IOException, UnknownHostException {
    
43. return sslContext.getSocketFactory().createSocket(socket, host, port,autoClose);
    
44. }
    
45. 
    
46. @Override
    
47. public Socket createSocket() throws IOException {
    
48. return sslContext.getSocketFactory().createSocket();
    
49. }
    
50. }

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. 
   
6. SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);
   
7. sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
   
8. 
   
9. HttpParams params = new BasicHttpParams();
   
10. HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    
11. HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
    
12. 
    
13. SchemeRegistry registry = new SchemeRegistry();
    
14. registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    
15. registry.register(new Scheme("https", sf, 443));
    
16. 
    
17. ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
    
18. 
    
19. return new DefaultHttpClient(ccm, params);
    
20. } catch (Exception e) {
    
21. return new DefaultHttpClient();
    
22. }
    
23. }

现在就可以拿这个HTTPClient去请求数据了！！！！！GOOD
