为什么我得到这个错误java.lang.IllegalArgumentException？

Question

为什么我得到这个错误：java.lang.IllegalArgumentException异常：该消费者期望类型的请求org.apache.http.HttpRequest

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： 刚刚更新接受的答案，因为它是不相关了。路标文档有点过时，并且由于HttpURLConnection上的错误，建议在Android中使用CommonsHttpOAuthConsumer。这些已被修复，现在Android删除了Apache HTTP，因此正确处理路标的方法是通过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

一旦你通过了不是最新的或完整的教程，或者特别有用的教程，路标在android，lol上的使用是微不足道的。

无论如何，这里是使用apache http而不是本地android来做到这一点的方法，为简洁起见，它有点难看，但应该让你启动并运行。

修改你的代码有点让它工作，你可能想让HttpClient在不同的调用中保持一致，但我只是将所有内容都内联了。我还注意到你正在反序列化令牌，所以我只是假设你有实际的OAuth流程工作。

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

Answer 2

它应该是你张贴request代码明显不HttpRequest型的...

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

Answer 3

异常java.lang.IllegalArgumentException异常被抛出时的方法需要的参数类型并接受另一种类型。
在这种情况下，该方法是sign和参数是request：

consumer.sign(request); 

如果它等待收到HTTPRequest类型和它的recieving另一种类型。
