Exception in thread "main" net.oauth.exception.OAuthException: HTTP/1.0 401 Unauthorized

    at net.oauth.consumer.OAuth1Consumer.createOAuthTokenResponse(OAuth1Consumer.java:142)
    at net.oauth.consumer.OAuth1Consumer.requestAccessToken(OAuth1Consumer.java:249)
    at net.oauth.consumer.OAuth1Consumer.requestAccessToken(OAuth1Consumer.java:226)
    at com.auth.Test1OAuth1.main(Test1OAuth1.java:84)

测试代码如下：package com.auth；

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URISyntaxException;
import java.util.HashMap;
import java.util.Map;
import net.oauth.consumer.OAuth1Consumer;
import net.oauth.exception.OAuthException;
import net.oauth.http.HttpClient;
import net.oauth.provider.OAuth1ServiceProvider;
import net.oauth.signature.OAuthSignature;
import net.oauth.signature.impl.OAuthHmacSha1Signature;
import net.oauth.token.oauth1.RequestToken;
import net.oauth.token.oauth1.AccessToken;

public class Test1OAuth1
{
    public static void main(String[] args) throws OAuthException, IOException,
            URISyntaxException
    {

        String client_id = "Consumer key";
        String client_secret = "Consumer secret";

        OAuth1Consumer consumer = new OAuth1Consumer(client_id, client_secret,
                new OAuth1ServiceProvider(
                        "https://api.twitter.com/oauth/request_token",
                        "https://api.twitter.com/oauth/authorize",
                        "https://api.twitter.com/oauth/access_token"));

        System.setProperty("proxySet", "true");
        System.setProperty("proxyHost", "xxx.xxx.xxxx.xxx");
        System.setProperty("proxyPort", "3128");
        HttpClient client = new HttpProxyClient();

        consumer.setClient(client);

        OAuthSignature oAuthSignature = new OAuthHmacSha1Signature();
        RequestToken requestToken = consumer.requestUnauthorizedToken(null,
                "http://127.0.0.1:8080", null, oAuthSignature);

        Map<String, String[]> map = new HashMap<String, String[]>();
        String url = consumer
                .createOAuthUserAuthorizationUrl(requestToken, map);

        System.out.println(url);

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        String verify = br.readLine();
        System.out.println(verify);
        AccessToken accessToken = consumer.requestAccessToken(null,
                requestToken, verify, oAuthSignature);
        System.out.println(accessToken.getToken());
        System.out.println(accessToken.getTokenSecret());
    }
}

HttpProxyClient 类与 HttpDefaultClient 相同，不同之处如下：

  if (System.getProperty("proxySet").equals("true"))
        {
            if (null == proxyLocation)
            {
                proxyLocation = new InetSocketAddress(
                        System.getProperty("proxyHost"),
                        Integer.parseInt(System.getProperty("proxyPort")));
                if (null == proxy)
                {
                    proxy = new Proxy(Proxy.Type.HTTP, proxyLocation);
                }
            }
            URLConnection uc = new URL(s).openConnection(proxy);
            urlConnection = (HttpURLConnection) uc;
        }
        else
        {
            urlConnection = (HttpURLConnection) new URL(s).openConnection();
        }
