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();

修改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，因此处理路标的正确方法现在通过 DefaultOAuthConsumer 。

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request不属于HttpRequest类型...

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

Answer 2

一旦你超越了那些不是最新的，完整的，或者特别有用的教程，那么路标在android，lol上使用是微不足道的。

无论如何这里有一种方法可以使用apache http而不是本机android来实现这一点，为了简洁起见它有点难看但是应该让你运行起来。

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。

祝你好运！

    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);

就是这样

当方法期望参数类型并且它接收到另一种类型时，抛出异常java.lang.IllegalArgumentException。
在这种情况下，方法为sign，参数为request：

consumer.sign(request);

它等待接收HTTPRequest类型并且它正在接收另一种类型。

public class BlockTicketPostOauth extends AsyncTask<String, Void, Integer> {
    ProgressDialog pd;
    String response;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();

            OAuthConsumer consumer = new CommonsHttpOAuthConsumer(YOUR CONSUMER KEY,YOUR CONSSUMER SECRETE); consumer.setTokenWithSecret(null, null);

            /* create Apache HttpClient */
            HttpClient httpclient = new DefaultHttpClient();

            /* Httppost Method */
            HttpPost httppost = new HttpPost(ul);

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

            // send json string to the server
            StringEntity paras =new StringEntity(JSONPayload);

            paras.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

            httppost.setEntity(paras);

            HttpResponse httpResponse= httpclient.execute(httppost);

            int statusCode = httpResponse.getStatusLine().getStatusCode();

            Log.i("response json:","status code is:"+statusCode);
            Log.i("response json:","status message?:"+httpResponse.getStatusLine().toString());

            /* 200 represents HTTP OK */
            if (statusCode ==  200) {
                /* receive response as inputStream */
                inputStream = httpResponse.getEntity().getContent();
                response = convertInputStreamToString(inputStream);

                Log.i("response json:","json response?:"+response);

            }
        } catch (Exception e) {
            Log.d("response error", e.getLocalizedMessage());
        }
        return result; //"Failed to fetch data!";
    }

    @Override
    protected void onPostExecute(Integer result) {

        if(pd.isShowing()){
            pd.dismiss();
        }
        /* Download complete. Lets update UI */
        if(result == 1){

            Toast.makeText(BusPassengerInfo.this,"response is reult suceess:"+response,Toast.LENGTH_SHORT).show();

//允许客户转到付款方式

        }else{
            Log.e("response", "Failed to fetch data!");
            Toast.makeText(BusPassengerInfo.this,"response is reult fail",Toast.LENGTH_SHORT).show();
        }

    }
}

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