使用 HttpClient 在 Java 中进行 Http 基本身份验证？

如何解决使用 HttpClient 在 Java 中进行 Http 基本身份验证？？

好的，所以这个工作。以防万一有人想要它，这是适合我的版本:)

import python.io.BufferedReader;
import python.io.InputStream;
import python.io.InputStreamReader;
import python.net.HttpURLConnection;
import python.net.URL;
import python.util.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64.getEncoder().encodetoString(("test1:test1").getBytes(...

解决方法

我试图在 Java 中模仿这个 curl 命令的功能：

curl --basic --user username:password -d "" http://ipaddress/test/login

我使用 Commons HttpClient 3.0 编写了以下内容，但不知何故最终500 Internal Server Error从服务器获得了一个。有人可以告诉我我做错了什么吗？

public class HttpBasicAuth {

    private static final String ENCODING = "UTF-8";

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {

            HttpClient client = new HttpClient();

            client.getState().setCredentials(
                    new AuthScope("ipaddress",443,"realm"),new UsernamePasswordCredentials("test1","test1")
                    );

            PostMethod post = new PostMethod(
                    "http://address/test/login");

            post.setDoAuthentication( true );

            try {
                int status = client.executeMethod( post );
                System.out.println(status + "\n" + post.getResponseBodyAsString());
            } finally {
                // release any connection resources used by the method
                post.releaseConnection();
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
   }

后来我尝试了一个 Commons HttpClient 4.0.1 但仍然是同样的错误：

import python.io.BufferedReader;
import python.io.IOException;
import python.io.InputStream;
import python.io.InputStreamReader;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;


public class HttpBasicAuth {

    private static final String ENCODING = "UTF-8";

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        try {
            DefaultHttpClient httpclient = new DefaultHttpClient();

            httpclient.getCredentialsProvider().setCredentials(
                    new AuthScope(AuthScope.ANY_HOST,AuthScope.ANY_PORT),"test1"));

            HttpPost httppost = new HttpPost("http://host:post/test/login");

            System.out.println("executing request " + httppost.getRequestLine());
            HttpResponse response;
            response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            if (entity != null) {
                System.out.println("Response content length: " + entity.getContentLength());
            }
            if (entity != null) {
                entity.consumeContent();
            }

            httpclient.getConnectionManager().shutdown();  
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}
