由于时间原因，这里只构建所有请求https都能通过的请求client

首先定义（重写）信任管理器

    public class SSLTrustManager implements javax.net.ssl.TrustManager,            javax.net.ssl.X509TrustManager ,HostnameVerifier{        public java.security.cert.X509Certificate[] getAcceptedIssuers() {            return null;        }         public boolean isServerTrusted(                java.security.cert.X509Certificate[] certs) {            return true;        }         public boolean isClientTrusted(                java.security.cert.X509Certificate[] certs) {            return true;        }         public void checkServerTrusted(                java.security.cert.X509Certificate[] certs, String authType)                throws java.security.cert.CertificateException {            return;        }         public void checkClientTrusted(                java.security.cert.X509Certificate[] certs, String authType)                throws java.security.cert.CertificateException {            return;        }                	@Override		public boolean verify(String urlHostName, SSLSession session) { //允许所有主机			return true;		}    }

然后封装

 public static HttpURLConnection connect(String strUrl) throws Exception {            	 javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];         javax.net.ssl.TrustManager tm = new SSLTrustManager();         trustAllCerts[0] = tm;         javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext                 .getInstance("SSL");         sc.init(null, trustAllCerts, null);         javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc                 .getSocketFactory());                  HttpsURLConnection.setDefaultHostnameVerifier((HostnameVerifier) tm);                 URL url = new URL(strUrl);        HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();             return urlConn;    }

测试一下

public void unitest(){     HttpURLConnection urlConn = connect('https://github.com/');        urlConn.setDoInput(true);        urlConn.setRequestMethod("GET");        urlConn.connect();        InputStream is = urlConn.getInputStream();        StringBuffer sb = new StringBuffer();        if(is!=null)        {        	BufferedReader br = new BufferedReader(new InputStreamReader(is));        	String s = null;        	while ((s=br.readLine())!=null)        	{				sb.append(s).append("\n");			}        }        System.out.println("Content:\n"+sb.toString());}

try do it!
