Question

我尝试使用HTTPS协议连接到网页。但其回归403回应。那么如何在不检查证书的情况下连接到HTTPS服务器。我从StackOverflow中提到了类似的代码。它适用于其他页面，但不适用于wireshark。

import java.io.IOException;
import java.net.URL;

public class wireshark {
    public static void main(String[] args) throws IOException {

        TrustManager[] trustAllCertificates = new TrustManager[] {
            new X509TrustManager() {

                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // TODO Auto-generated method stub

                }

                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // TODO Auto-generated method stub

                }

                public X509Certificate[] getAcceptedIssuers() {
                    // TODO Auto-generated method stub
                    return null;
                }

            }
        };

        HostnameVerifier trustAllHostnames = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true; // Just allow them all.
            }


        };

        try {
            URL url=new URL("https://ask.wireshark.org/questions/634/acc-to-wireshark-999-of-my-outgoing-packets-have-a-bad-checksum");
            System.setProperty("jsse.enableSNIExtension", "true");
            SSLContext sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCertificates, new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
            HttpsURLConnection.setDefaultHostnameVerifier(trustAllHostnames);

        //    HttpsURLConnection httpConnection=null ;


            HttpsURLConnection    httpConnection=  (HttpsURLConnection) url.openConnection();
            httpConnection.setHostnameVerifier(new AllowAllHostnameVerifier());
            System.out.println(httpConnection.getResponseCode());


        }
        catch (GeneralSecurityException e) {
            throw new ExceptionInInitializerError(e);
        }
    }
}

http 403错误通常与您通过HTTPS连接的方式无关（除非该站点需要客户端证书，而不是您的情况）。 403是禁止的错误代码，可能会被抛出以防止机器人和其他网络爬虫阅读他们的网站。通常，他们使用简单的方法，例如读取用户代理字段来停止机器人。默认情况下，Java程序都使用此用户代理：Java / version，例如Java / 1.8.0_66

在浏览器中以调试模式打开该页面，查看它发送的所有HTTP标头，然后尝试从您的程序发送相同的标题。
