java - ApacheHttpClientダイジェスト認証に失敗しました

Question

HttpClientライブラリを使用してダイジェスト認証を実行しようとしていますが、次のようになりますHTTP/1.1 401 Unauthorized。

Firefoxからのリクエストを試してみると、正常に機能し、正しく応答が返されるので、サーバー認証が正常に機能していることがわかります。

次のコードは私のために働いた

public class RestClient {

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

    HttpHost targetHost = new HttpHost("localhost", 8001, "http");
    DefaultHttpClient httpclient = new DefaultHttpClient();

    final String userName = "admin";
    final String password = "password";

    httpclient.getCredentialsProvider().setCredentials(
            new AuthScope("localhost", 8001), 
            new UsernamePasswordCredentials(userName, password));   


    // Create AuthCache instance
    AuthCache authCache = new BasicAuthCache();
    // Generate DIGEST scheme object, initialize it and add it to the local
    // auth cache
