无法通过代理隧道。代理通过https返回“HTTP / 1.1 407” [英] Unable to tunnel through proxy. Proxy returns “HTTP/1.1 407” via https
问题描述
我面临着java6 / 8的奇怪行为。
我尝试通过需要基本用户身份验证的代理进行隧道传输。
通过标准java身份验证器执行此操作。
如果我尝试访问https url作为第一个url,则抛出异常:
I am faced with a curious behaviour of java6/8. I try to tunnel through a proxy which needs basic user authentication. Doing this by the standard java Authenticator. If I try to access a https url as the first url, an exception is thrown:
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代理验证
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
但如果我先访问http URL然后访问https URL,则https访问可以正常工作。
But if I access a http URL first and then the https URL, the https access works fine.
鉴于代码:
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" );
}
任何建议,想法?
推荐答案
您必须编辑变量
jdk.http.auth.tunneling.disabledSchemes 和 jdk.http.auth。 proxying.disabledSchemes 如下所示为空白:
You have to edit the variables
jdk.http.auth.tunneling.disabledSchemes and jdk.http.auth.proxying.disabledSchemes to blank like this:
jdk.http.auth.tunneling.disabledSchemes=
jdk.http.auth.proxying.disabledSchemes=
在我的情况下,我在此发现file
In my case I found in this file
jdk1.8.0_111 / jre / lib / net.properties
jdk1.8.0_111/jre/lib/net.properties
