java使用jsoup時繞過https證書驗證

java 代碼

1. 增加一個工具類
2. 在jsoup獲取之前調用此方法

//your code
SSLHelper.init();
Connection connect = Jsoup.connect(url).userAgent(USER_AGENT);
connect.header("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
connect.header("Accept-Encoding", "gzip, deflate, sdch");
connect.header("Accept-Language", "zh-CN,zh;q=0.8");
connect.timeout(3000);
connect.ignoreHttpErrors(true);
Document doc = connect.get();

package com.bookmark.analysis.common.util;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.X509TrustManager;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class SSLHelper {

    public static String USER_AGENT = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 5.0)";

    static public void init() {
        try {
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, new X509TrustManager[]{new X509TrustManager() {
                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                }

                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                }

                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
            }}, new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
        } catch (NoSuchAlgorithmException e) {
        } catch (KeyManagementException e) {
        }
    }

}
