android - HTTP 请求失败

Question

我必须得到这样的 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

使用这段代码:

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);

我遇到这个异常，我怀疑它是由未编码的 URL 引起的，我该如何编码我的 URL？它不是由 HTTPURLConnection 自动编码的吗？ 异常:

非常感谢。

是的，您的 URL 中的数据包含错误的空格，可能导致您的请求不返回您期望解析的内容，请使用内置的 urlencoder。
