我一直在挣扎着过去的一天，为我的android应用程序实现OAuth。问题后我遇到了问题。我只想签署请求，将其发送到Web服务并获得回复（我相信这是两条腿的方法）。为什么这个错误：找不到类'oauth.signpost.http.HttpParameters
我已经下载路标：
-signpost核-1.2.1.2
，commonshttp4-1.2.1.2 -signpost
我已经添加了罐子到我的媒体库的构建路径。
是否有某处需要放置这些jar文件才能使它们工作？
我一直遇到麻烦最多的部分是生成签名并最终签署请求。错误一直在为HttpParemeters引发。
有没有办法让我以编程方式生成一个baseString？
有人可以指导我一个双腿Oauth android的具体例子，工程？
我下面的代码：
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() {
public void writeTo(OutputStream outstream) throws IOException {
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);
//get response
//StringBuffer response = new StringBuffer();
InputStream instream = null;
BufferedReader br = null;
try{
int respcode = response.getStatusLine().getStatusCode();
Log.i("Server Response", ""+respcode);
//get XML from InputStream
if(respcode>= 200){
instream = response.getEntity().getContent();
client.buildDoc(instream);
}
else{
Log.i("Server Response", ""+respcode);
//instream = request.getErrorStream();
}
}catch(Exception e){
Log.i("SPLASH","Unable to create connection stream");
e.printStackTrace();
}
finally {
if(instream != null) {
Log.i("SPLASH","Disconnecting stream");
instream.close();
}
}
*/
}
catch(Exception e){
Log.i("SPLASH","Unable to create connection");
e.printStackTrace();
}finally {
if(httpclient != null) {
Log.i("SPLASH","Disconnecting");
httpclient.getConnectionManager().shutdown();
}
}
}
/*

对不起，你是什么意思（用s！）？ – Fabii 2012-04-15 19:46:48
我是否创建一个libs文件夹，在我的包资源管理器层次结构中没有看到它。 – Fabii 2012-04-15 19:47:45
是的，在你的Android项目中创建一个libs文件夹（确保在Eclipse中安装了最新版本的ADT-Plugin） – 2012-04-15 19:48:56
