Android HTTP请求失败

我必须获得如下HTTP请求：

http://www.aroundertouch.com/queriesandroid1dot0/project/idProjet/45.484171;;9.050393;;Rotondi Group S.R.L. - Costruzione Macchine Abbigliamento/iphone/354781043339495/lang/en_US

使用此代码：

url = new URL(query);
   Log.d(TAG,url.toString());
      connection = url.openConnection();
      httpConnection = (HttpURLConnection)connection; 
      int responseCode = httpConnection.getResponseCode(); 
      // HTTP status okay
      if (responseCode == HttpURLConnection.HTTP_OK) { 
       // preparo stream 
       in = httpConnection.getInputStream();
       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
       DocumentBuilder db = dbf.newDocumentBuilder();
       dom = db.parse(in);      
      }
      // HTTP status fail 
      else{
       throw new Exception("responseCode != 200 OK in "+query);
      }
      in.close();
      httpConnection.disconnect();
      _ret = parseXML(dom);

我遇到了这个异常，我怀疑它是由未编码的URL引起的，我如何对我的URL进行编码？它不是由HTTPURLConnection自动编码的吗？ 免除：

非常感谢。

是的，URL中的数据包含不正确的空格，可能导致您的请求无法返回您希望解析的内容，请使用内置的URLCoder

确实如此。您可能会得到一个HTML文件。
