java抓取Https協議url地址的源碼的方法

閱讀本文以前，請先閱讀下文，經過下文將獲取到keystore文件：

在此，感謝一下stevenliu ，不過通過個人測試，發現stevenliu 文章中的源碼並無抓取到頁面源碼。多是我項目裏面的HttpClient版本較高的緣由。下面這個方法沒有問題：

package org.phoenix.cases.webservice;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.security.KeyStore;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.List;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;
import org.apache.commons.io.IOUtils;

在個人phoenixframework自動化平臺的接口測試模塊中，下個版本將會增長https的操做。由於發現如今愈來愈多的網站是https了。phoenixframework平臺網站：http://www.cewan.la
