Java 中出现 oauth_problem：signature_invalid 错误

Question

运行我的第一个 OAuth 提供者/消费者示例。

我的提供程序是在 Tomcat 7 上运行的以下 jsp

<%@page import="net.oauth.*, net.oauth.server.*" %>
<%
  String consumerSecret="testsecret";
  String consumerKey="testkey";

  OAuthMessage message=OAuthServlet.getMessage(request,null);
  OAuthConsumer consumer=new OAuthConsumer(null, consumerKey, consumerSecret, null);
  OAuthAccessor accessor=new OAuthAccessor(consumer);

  SimpleOAuthValidator validator=new SimpleOAuthValidator();
  validator.validateMessage(message,accessor);

  System.out.println("It must have worked"); 
%>

它源自 http://communitygrids.blogspot.com/2009/01/simple-oauth-client-and-server-examples.html

下面是我的消费者 端

import org.apache.commons.codec.binary.Base64;
import org.scribe.builder.ServiceBuilder;
import org.scribe.model.OAuthRequest;
import org.scribe.model.Response;
import org.scribe.model.Token;
import org.scribe.model.Verb;
import org.scribe.oauth.OAuthService;
import api.TradeKingAPI;

public class OAuthScribeTest {

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

        String url = "http://localhost:9080/OAuthTest/OAuthTest.jsp";
        String consumerSecret="testsecret";
        String consumerKey="testkey";
        OAuthService service = new ServiceBuilder()
        .provider(TradeKingAPI.class)
        .apiKey(consumerKey)
        .apiSecret(consumerSecret)
        .build();

        Token accessToken = new Token(consumerKey, consumerSecret);

        OAuthRequest request = new OAuthRequest(Verb.GET, url);

        service.signRequest(accessToken, request);
        Response response = request.send();
        System.out.println(response.getBody());

        int x = 0;
}

当我运行客户

时，我从提供者

oauth_signature: onPnFrUtighWHU0UrERD0Wg7mII=

oauth_signature_base_string 收到此错误响应： GET&http%3A%2F%2Flocalhost%3A9080%2FOAuthTest%2FOAuthTest.jsp&oauth_consumer_key%3Dtestkey%26oauth_nonce%3D2098 667235%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1317506767%26oauth_token%3Dtestkey%26oauth_version%3D1.0
