为什么我收到此错误java.lang.IllegalArgumentException？

Question

我为什么会收到此错误:java.lang.IllegalArgumentException:此消费者需要类型为org.apache.http.HttpRequest的请求

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

URL url = new URL(targetURL);
request = (HttpURLConnection) url.openConnection();

// sign the request
consumer.sign(request);
// send the request
request.connect();

编辑: 只是更新已接受的答案,因为它不再相关.由于HttpURLConnection上的错误,路标文档有点过时并建议在Android中使用CommonsHttpOAuthConsumer.这些已经修复,现在Android删除了Apache HTTP,因此现在通过DefaultOAuthConsumer处理路标的正确方法.

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

URL url = new URL(targetURL);
request = (HttpURLConnection) url.openConnection();

// sign the request

consumer.sign(request);

Answer 1

在您发布的代码中应该很明显,这request不是类型的HttpRequest...

request = (HttpURLConnection) url.openConnection();
consumer.sign(request);

Answer 2

路标在android,lol上使用很简单,一旦你超过了那些不是最新,完整或者特别有用的教程.

无论如何这里有一种方法来使用apache http而不是本机android,它为了简洁起见有点难看,但应该让你运行起来.

修改你的代码以使其工作,你可能想让HttpClient在调用之间保持一致但我只是内联了所有这些.我还注意到你正在对令牌进行反序列化,所以我只是假设你有实际的OAuth流程.

祝好运!

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

   // Use the apache method instead - probably should make this part persistent until
   // you are done issuing API calls    
   HttpParams parameters = new BasicHttpParams();
   HttpProtocolParams.setVersion(parameters, HttpVersion.HTTP_1_1);
   HttpProtocolParams.setContentCharset(parameters, HTTP.DEFAULT_CONTENT_CHARSET);
   HttpProtocolParams.setUseExpectContinue(parameters, false);
   HttpConnectionParams.setTcpNoDelay(parameters, true);
   HttpConnectionParams.setSocketBufferSize(parameters, 8192);

   HttpClient httpClient = new DefaultHttpClient();

   SchemeRegistry schReg = new SchemeRegistry();
   schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
   ClientConnectionManager tsccm = new ThreadSafeClientConnManager(parameters, schReg);

   httpClient = new DefaultHttpClient(tsccm, parameters);

   HttpGet get = new HttpGet(targetURL); 

    // sign the request
    consumer.sign(get);

    // send the request & get the response (probably a json object, but whatever)
    String response = httpClient.execute(get, new BasicResponseHandler());

    // shutdown the connection manager - last bit of the apache code 
    httpClient.getConnectionManager().shutdown();

    //Do whatever you want with the returned info 
    JSONObject jsonObject = new JSONObject(response);
