【问题描述】：

当使用 WinHttpClients 和 GET 请求时，我已经能够成功地对需要 ntlm 身份验证的服务进行身份验证。但是，当我尝试进行 POST 时，我总是得到 401 返回码。以前有人成功过吗？

import java.io.IOException;
import java.io.UnsupportedEncodingException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.NTCredentials;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.protocol.HttpClientContext;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.WinHttpClients;


public class WindowsAuthPOst 

public static void main (String []args) throws Exception, IOException

    org.apache.log4j.BasicConfigurator.configure();
    CloseableHttpClient httpclient = WinHttpClients.createDefault();

    HttpHost target = new HttpHost("SomeHost.domain", 443, "https");

    HttpClientContext context = HttpClientContext.create();
    HttpGet httpget = new HttpGet("/some/Service.svc");
    CloseableHttpResponse response1 = httpclient.execute(target, httpget, context);
    try 
        HttpEntity entity1 = response1.getEntity();
     finally 
        response1.close();
    

    // Execute an expensive method next reusing the same context (and connection)
    HttpPost httppost = new HttpPost("/some/Service.svc");
    httppost.setHeader("SOAPAction", "Some Soap Action");
    httppost.setEntity(new StringEntity("Soap Payload"));
    CloseableHttpResponse response2 = httpclient.execute(target, httppost, context);
    try 
        HttpEntity entity2 = response2.getEntity();
     finally 
        response2.close();
    

【参考方案1】：

您可以检查它是否可用。

    if (!WinHttpClients.isWinAuthAvailable()) 
        System.out.println("Integrated Win auth is not supported!!!");
    

如果没有，可能是您的类路径中没有jna.jar。它取决于 jna，如果它是 not there, see source code，它将在上面静默返回 false。

【讨论】：

它可用是因为它对 GET 有效，但对 POST 无效

【参考方案2】：

在发布前尝试使用 get（或 options）。由于 CORS，一些网络服务器需要这样做。 https://***.com/a/38410411/2376661
