如何在android中使用HttpURLConnection时提取Chunked数据

Question

我在进行REST API调用时使用HttpURLConnection来获取数据。

HttpURLConnection connection = (HttpURLConnection) (new URL("http://" + account + ".table.core.windows.net/"+urlPath)).openConnection();
connection..connect();

我得到的响应是使用WireShark找到的分块数据。 我希望数据显示在我的应用程序中。如何使用HttpURLConnection获取这个分块数据。 ?? 以下是wireshark的回复

以下代码适用于这种情况。

HttpURLConnection connection = (HttpURLConnection) (new URL("http://" + account + ".table.core.windows.net/"+urlPath)).openConnection();

    signRequestSK(connection, account, key);

    connection.connect();

    ByteArrayOutputStream sink = new ByteArrayOutputStream();

    copy(connection.getInputStream(), sink, 3000);  
    byte[] downloadedFile = sink.toByteArray();
    String str = new String(downloadedFile, "UTF8");


    AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setTitle("Title");
    alert.setMessage(str);
    alert.show();

复制功能

      public static void copy(InputStream in, OutputStream out , int bufferSize)
           throws IOException
        {
           // Read bytes and write to destination until eof
           byte[] buf = new byte[bufferSize];
           int len = 0;
           while ((len = in.read(buf)) >= 0)
           {
              out.write(buf, 0, len);
           }
        }
