java - 为什么这个错误: Could not find class 'oauth.路标.http.HttpParameters

Question

过去一天我一直在努力为我的 Android 应用程序实现 OAuth。我遇到了一个又一个的问题。我只想签署一个请求，将其发送到网络服务并获得响应(我相信这是两条腿的方法)。

我已经下载了路标:

-signpost-core-1.2.1.2

-signpost-commonshttp4-1.2.1.2

我已将 jar 添加到我的库构建路径中。

我需要在特定的地方放置这些 jar 文件才能使其工作吗？

我遇到最多麻烦的部分是生成签名并最终签署请求。 HttpParemeter 不断抛出错误。

有没有办法让我以编程方式生成 baseString ？

有人可以指导我一个可行的两条腿 Oauth android 特定示例吗？

我的代码如下:

public void excecuteSigning(String targetURL){
        String SOAP_ACTION = "http://amebatv.com/api/authDevice";
        System.setProperty("http.keepAlive", "false");      
        HttpURLConnection _request = null;  
        DefaultHttpClient httpclient = null;

    try{ 

        CONSUMER_SECRET  = app_pref.getString("consumerSecret", "");
        CONSUMER_KEY = app_pref.getString("consumerKey", "");   
        String oaut_token = app_pref.getString("accessToken", "");
        String tokenSecret = app_pref.getString("tokenSecret", "");
        String deviceId = deviceInfo.getSerial();


        CommonsHttpOAuthConsumer  consumer = new CommonsHttpOAuthConsumer (CONSUMER_KEY,CONSUMER_SECRET);
        consumer.setTokenWithSecret(oaut_token, tokenSecret); 

        //HttpRequest request;
        HttpParameters requestParameters = new HttpParameters();
        requestParameters.put("file", "vacation.jpg");
        requestParameters.put(OAuth.OAUTH_CONSUMER_KEY, "dpf43f3p2l4k3l03");
        requestParameters.put(OAuth.OAUTH_NONCE, "kllo9940pd9333jh");
        requestParameters.put(OAuth.OAUTH_SIGNATURE_METHOD, "HMAC-SHA1");
        requestParameters.put(OAuth.OAUTH_TIMESTAMP, "1191242096");
        requestParameters.put(OAuth.OAUTH_TOKEN, "nnch734d00sl2jdk");
        requestParameters.put(OAuth.OAUTH_VERSION, "1.0");
        requestParameters.put("size", "original");


        HttpPost request = new HttpPost(targetURL);
        SignatureBaseString baseString = new SignatureBaseString((HttpRequest) request, requestParameters);

        String base = baseString.generate();
        System.out.println(":"+base);

        System.out.println(computeHmac(base,"kd94hf93k423kf44&pfkkdhi9sl3r4s00"));

       httpclient = new DefaultHttpClient();

        ContentProducer cp = new ContentProducer() {

                Writer writer = new OutputStreamWriter(outstream, "UTF-8");
                writeXml(writer);
            }
        };

       HttpParameters params = new HttpParameters();
       HttpEntity entity = new EntityTemplate(cp);
       HttpPost request = new HttpPost(targetURL);         

       request.addHeader("Authorization",AUTH_HEADER);
       request.addHeader("Content-Type", "text/xml; charset=utf-8");
       //request.addHeader("Content-Length",""+soapXML.getBytes().length);
       request.addHeader("SOAPAction",SOAP_ACTION);
       request.setEntity(entity);

        // sign the request
        consumer.sign(request);
        // send the request
        //request.connect();
        HttpResponse response = httpclient.execute(request);

                instream =  response.getEntity().getContent();

库需要位于 libs 文件夹中(带有 s!)，然后它们会自动添加到项目的构建路径中。
