我正试图打开这个uri
https://some-host/a/meta? (this url is passed to proxi.jsp page)
..但它重定向到身份验证服务（在https上），弹出一个用户名和密码的框...如果在浏览器上..那么它需要你输入凭据..然后它回到第一个链接我试图打开并显示内容...所以我想知道，当这个中间重定向到身份验证服务发生..如何通过代码输入我的用户名和密码到弹出窗口...我试图使用apache HttpClient来做到这一点...
这是我发出请求的proxi.jsp代码..
<%@ page language="java" import="
java.util.Collection,
org.apache.commons.httpclient.HttpClient,
org.apache.commons.httpclient.UsernamePasswordCredentials,
org.apache.commons.httpclient.auth.AuthScope,
org.apache.commons.httpclient.methods.GetMethod"
contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%
try {
String a_Url = request.getParameter( "url" ) ;
HttpClient client = new HttpClient();
client.getState().setCredentials(
new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, "realm"),
new UsernamePasswordCredentials("test", "pass")
);
GetMethod get = new GetMethod(a_Url);
get.setDoAuthentication( true );
try {
int status = client.executeMethod( get );
out.println(status + "\n" + get.getResponseBodyAsString());
} finally {
get.releaseConnection();
}
} catch (Throwable t) {
t.printStackTrace();
}
%>
这是我得到的错误： -

如果我尝试粘贴此网址
https://login.xyz.com/9]&AUTHREASON=0&METHOD=GET@Name
回到浏览器然后我得到一个用于身份验证的弹出窗口，如果我在该窗口中写入我的用户名和密码，那么我将获得我正在寻找的实际内容。 在proxi.jsp页面中是否有任何标题需要传递。因为在页面中传递用户名和密码不是最好的方法。或者任何其他方式。任何建议将不胜感激..

不确定该网站是否使用基本身份验证 - 您可以尝试以下操作，其中test是用户名，pass是您输入的网站的密码。
https://test:pass@some-host/a/getmeta?id=10

您必须使用HttpClient 3.1，因为我的测试表明HttpClient 3.0对该URL没问题。但是HttpClient 3.1在到达查询字符串中的[时会引发错误。为什么会这样，我不确定。根据{{3}}，应允许[和]。查看HttpClient 3.1中的RFC 3986源，由于某种原因，它不包含这些字符。这可能是我会说的那个版本的错误。话虽如此，我认为没有任何工作可以进入HttpClient 3.x，因为4.x现在是焦点。
答案 2 :(得分：0)
根据例外情况，可以访问网址https://login.host.com/。
最后写的URL指向不同的位置。
https://login.host.com/ --> Unreachable
https://login.somehost.com/ --> Reachable
两个网址都不相等
