Android ignore https certificate verification
通过Https访问的时候经常会遇到"Not trusted Server Certificate"的问题，有人说在3.0上面没有这个问题，可能已经改进了，在2.2及以前的版本中有这个问题。
开始想的是采用安装证书的方法(Trusting SSL certificates），最后也没有成功，不知道是证书的原因还是其他，有人说安装证书只能在WIFI上使用，没有找到官方文档，用户可能在GPRS上使用，只能放弃。
StackOverflow上也有相关的方案，我整理了一下。
我将注册的步骤封装到DefaultHttpClient子类中了，这样看上去更清晰一些，你也可以
直接实例化DefaultHttpClient的方法。
1. SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme ("https", sslf, 443));
2. SingleClientConnManager cm = new
3. SingleClientConnManager(post.getParams(), schemeRegistry);
4. HttpClient client = new DefaultHttpClient(cm, post.getParams());
1. /**

5. public class SSLHttpClient extends DefaultHttpClient {
6.
7. @Override
8. protected ClientConnectionManager createClientConnectionManager() {
9. SchemeRegistry registry = new SchemeRegistry();
10. registry.register(new Scheme("http", PlainSocketFactory
11. .getSocketFactory(), 80));
//443是Https的默认端口，如果网站配置的端口不一样，这里要记着改一下
12. registry.register(new Scheme("https", new EasySSLSocketFactory(), 443));
13. return new SingleClientConnManager(getParams(), registry);
14.
15. }
16.
17. public static SSLHttpClient getInstance() {
18. SSLHttpClient client = new SSLHttpClient();
19. client.setCookieStore(mCookie);
20. return client;
21. }
22. }
