Question

在C＃代码中，我们使用网络身份验证：

req = HttpWebRequest.Create(Url)
req.Method = "POST"
req.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate")
req.Credentials = New NetworkCredential(Username, Password)

我们需要在Java中实现它。我尝试过两种方法，但它不起作用：

httppost.setHeader（＆＃34;授权＆＃34;，＆＃34;基本＆＃34; +＆＃34;用户名：密码＆＃34;）;
Authenticator.setDefault（new PaswordAuthentication（））;

但两者都不起作用。任何领导都将受到高度赞赏。

虽然以下link回答了问题，但它没有显示使用HttpClientBuilder的完整解决方案。以下是从需要Windows身份验证的IIS服务器获取索引文件的完整示例。

package test;

import java.util.*;

import org.apache.http.*;
import org.apache.http.auth.*;
import org.apache.http.client.*;
import org.apache.http.client.config.*;
import org.apache.http.client.methods.*;
import org.apache.http.impl.client.*;
import org.apache.http.util.*;

public class Test 
{
    public static void main(String[] args)
    {
        try
        {
            RequestConfig requestConfig = RequestConfig.custom()
                .setTargetPreferredAuthSchemes(Arrays.asList(AuthSchemes.NTLM))
                .setProxyPreferredAuthSchemes(Arrays.asList(AuthSchemes.BASIC))
                .build();

            CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
            credentialsProvider.setCredentials(AuthScope.ANY,
                new NTCredentials("USERNAME", "PASSWORD", "HOSTNAME", "DOMAIN"));

            HttpClient httpclient = HttpClients.custom()
                .setDefaultCredentialsProvider(credentialsProvider)
                .setDefaultRequestConfig(requestConfig)
                .build();

            HttpHost target = new HttpHost("localhost", 80, "http");
            HttpGet httpget = new HttpGet("/");
            HttpResponse r = httpclient.execute(target, httpget);
            HttpEntity e = r.getEntity();
            String responseString = EntityUtils.toString(e, "UTF-8");
            System.out.println(responseString);
        }
        catch (Exception ex)
        {
            System.out.println(ex.getMessage());
        }
    }
}

Answer 2

您是否尝试过org.apache.commons.httpclient.NTCredentials？

这里有link个样本。

Java相当于NetworkCredential
