如何将带有用户名和密码的代理添加到Jsoup？

编程问答 2022-08-16

问题描述

我正在开发一个Java应用程序，该应用程序需要通过代理（使用用户名和密码）连接到Internet。但这是行不通的。有人可以帮我解决这个问题吗？我的Java代码如下：

    final String authUser = "username";
    final String authPassword = "password";

    Authenticator.setDefault(new Authenticator() {
        public PasswordAuthentication getpasswordAuthentication() {
            return new PasswordAuthentication(authUser,authPassword.tochararray());
        }
    });

    System.setProperty("http.proxyHost","192.123.12.123");
    System.setProperty("http.proxyPort","1234");

    Document doc = null;
    try {
        doc = Jsoup 
                .connect("https://www.google.com").timeout(60000)
                .header("Content-Language","en-US")
                .get();

    } catch (IOException e) {
        e.printstacktrace();
    }

解决方法

您可以尝试以下方法：

System.setProperty("http.proxyUser","username");
System.setProperty("http.proxyPassword","password");

或

System.setProperty("https.proxyUser","username");
System.setProperty("https.proxyPassword","password");
,

我遇到了这个错误：

我想通过代理访问网页（例如gooogle.com）（例如：“ 192.123.12.123:123”，并使用用户名和密码）
