为什么会出现java.lang.IllegalArgumentException错误？

为什么会出现此错误：java.lang.IllegalArgumentException：此使用者需要org.apache.http.HttpRequest类型的请求

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。路标文档有点过时，建议在Android中使用CommonHttpOAuthConsumer，因为HttpURLConnection上有bug。这些已经被修复，现在Android删除了ApacheHTTP，因此处理路标的正确方法现在是通过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);

---

在您发布的代码中应该很明显，

request

不是

HttpRequest

类型

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

---

当方法需要参数类型且接收到另一种类型的参数时，会引发异常java.lang.IllegalArgumentException。
在这种情况下，方法是

符号

，参数是

请求

：

consumer.sign(request); 

---

它正在等待接收

HTTPRequest

类型，而它正在接收另一个类型。

路标在android上使用非常简单，lol，一旦你通过了那些不是真正最新的、不完整的、或者不是特别有用的教程

无论如何，这里有一种方法可以使用ApacheHTTP而不是本机android来实现这一点，为了简洁起见，这有点难看，但应该可以让您启动并运行

对代码进行了一些修改以使其工作，您可能希望使HttpClient在调用之间保持一致，但我只是将所有这些都内联。我还注意到您正在反序列化令牌，因此我将假设您已经实现了实际的OAuth流

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

那么你是说这个网站是正确的您正在使用ApacheCommonsHTTP吗？你是为Android写这篇文章的吗？那篇文章中有很多警告。这可能与此相关：如果您需要对其他HTTP请求类型的请求进行签名，请查看中的示例SupportedHttpLibraries@Fabii-是的，那里的教程没有显示Apache Http的使用，这是Android应用程序所必需的，因为Android处理程序中有一个bug。特拉维斯给你指出了正确的方向。看看我下面的答案，看看能与android和Signpost@Idistic你的答案现在在上面| o |看看我提供的答案（两人一起）遇到了同样的问题，概述的解决方案对我有效。是否有生成签名的内置路标方法？@Fabii不确定我是否完全理解你的问题，sign方法为您处理几乎所有的事情，或者您是否正在寻找一种半自动的助手方法来自己构造签名，以便您可以修改？（比如nonce、令牌等）我想知道，既然HttpClient在android中已被弃用，HTTPUrlConnection是如何做到这一点的
