Java https 证书验证

在Java中，访问HTTPS网站时需要验证服务器证书以保证安全性。然而，在某些情况下我们可能需要绕过这种证书验证，例如开发调试、测试等环境中。那么，Java如何绕过https证书验证呢？下面有一种简单有效的方法。

示例代码：


import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
public class HttpsUtil {
  /**
   * 绕过https证书验证
   */
  public static void trustAllHttpsCertificates() throws Exception {
    TrustManager[] trustAllCerts = new TrustManager[1];
    TrustManager tm = new MyTrustManager();
    trustAllCerts[0] = tm;
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, null);
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
  }
  static class MyTrustManager implements TrustManager, X509TrustManager {
    public X509Certificate[] getAcceptedIssuers() {
      return null;
    }
    public boolean isServerTrusted(X509Certificate[] certs) {
      return true;
    }
    public boolean isClientTrusted(X509Certificate[] certs) {
      return true;
    }
    public void checkServerTrusted(X509Certificate[] certs, String authType)
        throws CertificateException {
      return;
    }
    public void checkClientTrusted(X509Certificate[] certs, String authType)
        throws CertificateException {
      return;
    }
  }
  /**
   * 绕过https证书验证
   */
  public static void ignoreSsl() {
    try {
      trustAllHttpsCertificates();
      HostnameVerifier hv = new HostnameVerifier() {
        public boolean verify(String urlHostName, SSLSession session) {
          return true;
        }
      };
      HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

以上代码实现了一个忽略SSL证书的工具类，其中MyTrustManager类和ignoreSsl方法实现了绕过证书验证的功能。
