Question

我有一个网站，其中一些页面是HTTP，另一些是HTTPS。我需要在HTTP页面获取HTTPS的值。我正在使用Java和Tomcat 7.实际上我使用request.getparameter()获得了JSP页面中的值。但在那个空格和'@'符号就像加密值显示一些额外的符号。请问如何解决这个问题。

提前致谢。

您可以使用javax.net.ssl.HttpsURLConnection。请按照以下示例：

import java.net.MalformedURLException;
import java.net.URL;
import java.security.cert.Certificate;
import java.io.*;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLPeerUnverifiedException;

public class HttpsClient{

   public static void main(String[] args)
   {
        new HttpsClient().testIt();
   }

   private void testIt(){
      String https_url = "https://www.google.com/";
      URL url;

      try {
        url = new URL(https_url);
        HttpsURLConnection con = (HttpsURLConnection)url.openConnection();

        //dumpl all cert info
        print_https_cert(con);

        //dump all the content
        print_content(con);
      } 
      catch (MalformedURLException e) {
        e.printStackTrace();
      } 
      catch (IOException e) {
        e.printStackTrace();
      }
   }

   private void print_https_cert(HttpsURLConnection con){
    if(con!=null){
      try {
        System.out.println("Response Code : " + con.getResponseCode());
        System.out.println("Cipher Suite : " + con.getCipherSuite());
        System.out.println("\n");

        Certificate[] certs = con.getServerCertificates();
        for(Certificate cert : certs){
           System.out.println("Cert Type : " + cert.getType());
           System.out.println("Cert Hash Code : " + cert.hashCode());
           System.out.println("Cert Public Key Algorithm : " + cert.getPublicKey().getAlgorithm());
           System.out.println("Cert Public Key Format : " + cert.getPublicKey().getFormat());
           System.out.println("\n");
        }
      } 
      catch (SSLPeerUnverifiedException e) {
        e.printStackTrace();
      } 
      catch (IOException e){
        e.printStackTrace();
      }
    }
  }

  private void print_content(HttpsURLConnection con){
    if(con!=null){
      try {
        System.out.println("****** Content of the URL ********");      
        BufferedReader br = new BufferedReader( new InputStreamReader(con.getInputStream()) );

        String input;

        while ((input = br.readLine()) != null){
           System.out.println(input);
        }

        br.close();
      } 
      catch (IOException e) {
         e.printStackTrace();
      }
    }
  }
}

<强>输出：

Response Code : 200
Cipher Suite : SSL_RSA_WITH_RC4_128_SHA

Cert Type : X.509
Cert Hash Code : 7810131
Cert Public Key Algorithm : RSA
Cert Public Key Format : X.509

Cert Type : X.509
Cert Hash Code : 6042770
Cert Public Key Algorithm : RSA
Cert Public Key Format : X.509

****** Content of the URL ********
<!doctype html><html><head><meta http-equiv="content-type" ......
