Http post请求取消NTLM身份验证(java)

HTTP POST请求取消NTLM身份验证（Java）

NTLM（Windows NT LAN Manager）是一种Windows操作系统中常用的身份验证协议。在某些情况下，我们可能需要在Java中发送HTTP POST请求时取消NTLM身份验证。下面是一些关于如何实现这一点的方法：

使用Apache HttpClient库发送HTTP POST请求，并设置身份验证策略为无身份验证：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.CoreProtocolPNames;

public class HttpPostExample {
    public static void main(String[] args) {
        try {
            HttpClient client = HttpClientBuilder.create().build();
            HttpPost post = new HttpPost("http://example.com/api/endpoint");
            
            // 设置请求体
            StringEntity entity = new StringEntity("request body");
            post.setEntity(entity);
            
            // 取消NTLM身份验证
            post.getParams().setParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, Boolean.FALSE);
            
            HttpResponse response = client.execute(post);
            HttpEntity responseEntity = response.getEntity();
            
            // 处理响应
            // ...
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

使用Java的URLConnection类发送HTTP POST请求，并设置请求头中的Authorization字段为null：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpPostExample {
    public static void main(String[] args) {
        try {
            URL url = new URL("http://example.com/api/endpoint");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            
            // 设置请求头
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setRequestProperty("Authorization", null); // 取消NTLM身份验证
            
            connection.setDoOutput(true);
            
            // 设置请求体
            String requestBody = "request body";
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(requestBody.getBytes());
            outputStream.flush();
            
            int responseCode = connection.getResponseCode();
            
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            
            reader.close();
            
            // 处理响应
            // ...
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这些方法可以帮助我们在Java中发送HTTP POST请求时取消NTLM身份验证。请注意，这些示例代码仅供参考，实际使用时需要根据具体情况进行适当的修改。
