从黑莓中的url获取数据

我有一个文件的网址“http://www.example.com/123.aes”（它包含超过2MB的mp3文件的数据）。现在我想从这个网址获取数据。当我尝试 http 连接来获取数据时，它显示错误 -请求的实体太大。如何解决这个问题呢 ？。 我的代码如下 -

 try {
    HttpConnection httpConn = (HttpConnection) Connector.open(httpURL, Connector.READ, true);
    final int iResponseCode = httpConn.getResponseCode();
    Dialog.alert(iResponseCode+"");
    InputStream is = httpConn.openInputStream();
    byte[] data = net.rim.device.api.io.IOUtilities.streamToBytes(is);
    String result = new String(data);
    Dialog.alert(result);

    FileConnection conn = (FileConnection)Connector.open("file:///store/home/user/pictures/"+System.currentTimeMillis()+".mp3", Connector.READ_WRITE);
    conn.create();
    OutputStream out = conn.openOutputStream();
    out.write(data);
    out.flush();
    out.close();
    conn.close(); 
   } catch (IOException e) {
    Dialog.alert(e+"");
    }

我还想将其另存为 mp3 文件在手机内存中。

希望对你有帮助。尝试以下功能：

public static String getPage(String url) {    
    String response = "";
    try {
        HttpConnection conn = 
            (HttpConnection)Connector.open(url,Connector.READ_WRITE);
        InputStream input =conn.openInputStream(); 
        byte[] data = new byte[256];
        int len = 0;
        StringBuffer raw = new StringBuffer();
        while( -1 != (len = input.read(data))) {
            raw.append(new String(data, 0, len));
        }
        response = raw.toString();
        input.close();
    } 
    catch(Exception e) {
        Dialog.alert(e.toString());
    }
    return response;
}

调用此函数的示例，

getPage("yourUrl;deviceside=true;interface=wifi");
