1、WebClientDevWrapper

package cn.edu.nuc.https;
    
    import javax.net.ssl.SSLContext;
    import javax.net.ssl.TrustManager;
    import javax.net.ssl.X509TrustManager;
    
    import org.apache.http.client.HttpClient;
    import org.apache.http.conn.ClientConnectionManager;
    import org.apache.http.conn.scheme.Scheme;
    import org.apache.http.conn.scheme.SchemeRegistry;
    import org.apache.http.conn.ssl.SSLSocketFactory;
    import org.apache.http.impl.client.DefaultHttpClient;
    
    public class WebClientDevWrapper {
    	public static HttpClient wrapClient(HttpClient base) throws Exception {
            SSLContext ctx = SSLContext.getInstance("TLS");
            X509TrustManager tm = new X509TrustManager() {
                @Override
                public void checkClientTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {
                }
    
                @Override
                public void checkServerTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {
                }
    
                @Override
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new java.security.cert.X509Certificate[0];
                }
            };
            ctx.init(null, new TrustManager[]{tm}, null);
            SSLSocketFactory ssf = new SSLSocketFactory(ctx);
            ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            ClientConnectionManager ccm = base.getConnectionManager();
            SchemeRegistry sr = ccm.getSchemeRegistry();
            sr.register(new Scheme("https", ssf, 443));
            return new DefaultHttpClient(ccm, base.getParams());
        }
    }

2、测试代码：

package cn.edu.nuc.https;
    
    import java.io.BufferedReader;
    import java.io.InputStreamReader;
    
    import org.apache.http.HttpResponse;
    import org.apache.http.client.HttpClient;
    import org.apache.http.client.methods.HttpGet;
    import org.apache.http.impl.client.DefaultHttpClient;
    
    public class TestHttps {
    	
    	public void testHttpGet() throws Exception {
    		HttpClient client =WebClientDevWrapper.wrapClient(new DefaultHttpClient());
    
    	    /*HttpPost post = new HttpPost("https://localhost:8443/login");
    //	    StringEntity entity = new StringEntity("user=test@abc.com&pwd=111&type=x");
    //	    post.setEntity(entity);
    	    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    	    nameValuePairs.add(new BasicNameValuePair("user", "test@abc.com"));
    	    nameValuePairs.add(new BasicNameValuePair("pwd", "111"));
    	    nameValuePairs.add(new BasicNameValuePair("type", "x"));
    	    post.setEntity(new UrlEncodedFormEntity(nameValuePairs));*/
    	    
    	    // 访问支付宝
    	 	HttpGet httpget = new HttpGet("https://www.alipay.com/");
    	    HttpResponse res = client.execute(httpget);
    	    System.out.println(res.getStatusLine());
    	    BufferedReader br = new BufferedReader(new InputStreamReader(res.getEntity().getContent(),"utf-8"));
    	    String line = br.readLine();
    	    while (line != null) {
    	        System.out.println(line);
    	        line = br.readLine();
    	    }
    	    client.getConnectionManager().shutdown();
    	}
    	
    	public static void main(String...strings) throws Exception {
    		new TestHttps().testHttpGet();
    	}
    }
