使用 Java 进行身份验证的 HTTP 代理 [英] Authenticated HTTP proxy with Java

问题描述

如何配置用户名和密码以使用 Java 对 http 代理服务器进行身份验证?

How can I configure the username and password to authenticate a http proxy server using Java?

我刚刚找到了以下配置参数:

I just found the following configuration parameters:

http.proxyHost=<proxyAddress>
http.proxyPort=<proxyPort>
https.proxyHost=<proxyAddress>
https.proxyPort=<proxyPort>

但是，我的代理服务器需要身份验证.如何配置我的应用以使用代理服务器?

But, my proxy server requires authentication. How can I configure my app to use the proxy server?

推荐答案

(正如 OP 所指出的，使用 java.net.Authenticator 也是必需的.我正在更新为了正确起见，我的回答相应地.)

( As pointed out by the OP, the using a java.net.Authenticator is required too. I'm updating my answer accordingly for the sake of correctness.)

(编辑#2:正如另一个答案中所指出的，在 JDK 8 中需要删除 basic 来自 jdk.http.auth.tunneling.disabledSchemes 属性的身份验证方案)

(EDIT#2: As pointed out in another answer, in JDK 8 it's required to remove basic auth scheme from jdk.http.auth.tunneling.disabledSchemes property)

对于认证，使用java.net.Authenticator设置代理的配置并设置系统属性http.proxyUser和http.proxyPassword.

For authentication, use java.net.Authenticator to set proxy's configuration and set the system properties http.proxyUser and http.proxyPassword.

final String authUser = "user";
final String authPassword = "password";
Authenticator.setDefault(
  new Authenticator() {
    @Override
    public PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication(authUser, authPassword.toCharArray());
    }
  }
);

System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);

System.setProperty("jdk.http.auth.tunneling.disabledSchemes", "");
