          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.    /**

  4.     */  
  5.    public   class  SSLHttpClient  extends  DefaultHttpClient {
  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);
  15.       }
  17.        public   static  SSLHttpClient getInstance() {
  18.           SSLHttpClient client =  new  SSLHttpClient();
  19.           client.setCookieStore(mCookie);

  63.            return   this .standardTrustManager.getAcceptedIssuers();

      然后直接实例化SSLHttpClient就可以想Http一样执行HttpGet和HttpPost方法了,希望能有所帮助:)。
