HTTP request no peer certificate Solution

Many users encounter javax.net. SSL. sslpeerunverifiedexception: no peer certificate exceptions when making HTTP requests for Sina authorization or Sina data. The solution is provided (tested ).


Write a custom class to inherit 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. 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. }

Copy code

Let's take a look at how to perform callback:

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. }

Copy code

Now, you can use this httpclient to request data !!!!! Good
