无法通过代理隧道.代理通过https返回"HTTP/1.1 407"

Question

我面临着java6/8的奇怪行为.我尝试隧道通过需要基本用户身份验证的代理.通过标准的java Authenticator执行此操作.如果我尝试访问https url作为第一个url,则抛出异常:

java.io.IOException:无法通过代理进行隧道传输.代理返回"需要HTTP/1.1 407代理身份验证"

但是,如果我首先访问http URL,然后访问https URL,则https访问可以正常工作.

鉴于该代码:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Authenticator;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.PasswordAuthentication;
import java.net.Proxy;
import java.net.URL;

public class ProxyPass {
    public ProxyPass( String proxyHost, int proxyPort, final String userid, final String password, String url ) {

    try {
            /* Create a HttpURLConnection Object and set the properties */
            URL u = new URL( url );
            Proxy proxy = new Proxy( Proxy.Type.HTTP, new InetSocketAddress( proxyHost, proxyPort ) );
            HttpURLConnection uc = (HttpURLConnection) u.openConnection( proxy );

            Authenticator.setDefault( new Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    if (getRequestorType().equals( RequestorType.PROXY )) {
                        return new PasswordAuthentication( userid, password.toCharArray() );
                    }
                    return super.getPasswordAuthentication();
                }
            } );
            uc.connect();
            /* Print the content of the url to the console. */
            showContent( uc );
        }
        catch (IOException e) {
            e.printStackTrace();
        }
    }

    private void showContent( HttpURLConnection uc ) throws IOException {
        InputStream i = uc.getInputStream();
        char c;
        InputStreamReader isr = new InputStreamReader( i );
        BufferedReader br = new BufferedReader( isr );
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println( line );
        }
    }

    public static void main( String[] args ) {
        String proxyhost = "proxyHost";
        int proxyport = proxyPort;
        final String proxylogin = proxyUser;
        final String proxypass = proxyPass;

        String url = "http://www.google.de";
        String surl = "https://www.google.de";

//            new ProxyPass( proxyhost, proxyport, proxylogin, proxypass, url );  // uncomment this line to see that the https request works!
//            System.out.println( url + " ...ok" );   // uncomment this line to see that the https request works!
        new ProxyPass( proxyhost, proxyport, proxylogin, proxypass, surl );
        System.out.println( surl + " ...ok" );
    }

有什么建议,想法？

Answer 1

Java 8 Update 111中的更改​​:

现在,默认情况下,在为HTTPS设置隧道时需要基本身份验证的代理将不再成功.如果需要,可以通过从jdk.http.auth.tunneling.disabledSchemes网络属性中删除Basic,或者通过在命令行上将同名的系统属性设置为""(空)来重新激活此身份验证方案.

你的选择:

• 通过升级代理的身份验证方案(例如摘要访问身份验证)来解决问题(为了安全起见)

• 或者通过运行Java来解决问题

  java -Djdk.http.auth.tunneling.disabledSchemes=""
  

Answer 2

您必须将变量jdk.http.auth.tunneling.disabledSchemes和jdk.http.auth.proxying.disabledSchemes编辑 为空白,如下所示:

jdk.http.auth.tunneling.disabledSchemes=
jdk.http.auth.proxying.disabledSchemes=

就我而言,我在这个文件中找到了

jdk1.8.0_111/JRE/LIB/net.properties
