Android: java.lang.IllegalStateException: Scheme 'http' 未注册 - HTTPS 调用错误

Question

我有以下代码，用于检查与特定服务器的二级互联网连接。

HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;
                        SchemeRegistry registry = new SchemeRegistry();
                        SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
                        socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
                        registry.register(new Scheme("https", socketFactory, 8443));

                        DefaultHttpClient client = new DefaultHttpClient();

                        SingleClientConnManager mgr = new SingleClientConnManager(client.getParams(), registry);
                        DefaultHttpClient httpClient = new DefaultHttpClient(mgr, client.getParams());


                        HttpParams httpParameters = new BasicHttpParams();
                        HttpConnectionParams.setConnectionTimeout(httpParameters, Constants.HTTP_CONNECTION_TIMEOUT);

                        HttpConnectionParams.setSoTimeout(httpParameters, Constants.HTTP_CONNECTION_TIMEOUT);

                        HttpGet httpget = new HttpGet(Utility.getCloudUrl());

                        try {
                            HttpResponse response = httpClient.execute(httpget);

                            BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
                            StringBuffer sb = new StringBuffer("");
                            String l = new String();
                            while ((l = in.readLine()) !=null){
                                sb.append(l);
                            }
                            in.close();
                            String data = sb.toString();
                            if (data.length() > 0){

                                synchronized (lock) {
                                    isInternetAvialbale = true;
                                }
                                listener.onInternetReachable();

                            }else{


                                synchronized (lock) {
                                    isInternetAvialbale = false;
                                }
                                listener.onInternetNotReachable();
                            }
                        } catch (IOException e) {


                            synchronized (lock) {
                                isInternetAvialbale = false;
                            }
                            listener.onInternetNotReachable();
                            return;
                        }

在 Wifi 网络上一切正常。但是当这段代码在 3g 网络上执行时，出现以下异常:

java.lang.IllegalStateException: Scheme 'http' not registered.

我确实搜索了几个类似的问题，但无法理解。 有人可以帮我解决这个问题吗？

如果您使用组织的 WiFi 连接到互联网，请确保您可以访问互联网(而不仅仅是连接到互联网)。如果 WiFi 访问需要登录，请先登录，然后继续 HTTP/HTTPS 请求。
