从黑莓网址获取数据 [英] get data from url in blackberry

问题描述

我有一个文件的URL的http://www.example.com/123.aes（它包含2MB人数超过一个MP3文件的数据）。现在，我想从这个网址获取数据。当我试图HTTP连接获取数据，其显示错误 - 请求实体过大。如何解决这个问题？
我的code为如下 -

I have a url of a file "http://www.example.com/123.aes" ( it contains data of a mp3 file with morethan 2MB). Now i want to fetch the data from this url. When i tried http connection to get data, its showing an error - Requested entity too large. How to solve this problem ?. my code is given below -

 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+"");
    }

我也想将其保存为MP3文件在手机内存中。

Also i want to save it as mp3 file in phone memory.

推荐答案

最后，我得到了答案 -

Finally I got the answer -

ConnectionFactory connFact = new ConnectionFactory();
ConnectionDescriptor connDesc;
connDesc = connFact.getConnection(httpURL);
HttpConnection httpConn = (HttpConnection) connDesc.getConnection();
   try {
    httpConn.setRequestMethod(HttpConnection.GET);
    InputConnection inputConn = (InputConnection) httpConn;
    InputStream is = inputConn.openInputStream();
    byte[] data =IOUtilities.streamToBytes(is);
    Dialog.alert(original.toString());
    FileConnection conn = (FileConnection)Connector.open("file:///store/home/user/pictures/"+System.currentTimeMillis()+".mp3", Connector.READ_WRITE);
    conn.create();
    OutputStream out = conn.openOutputStream();
    out.write(original);
    out.flush();
    out.close();
    conn.close();  
   } catch (IOException e) {
      Dialog.alert(e+"");
   }
