获取Android中网页的大小（以字节为单位）

Question

如何使用Android计算html（仅限html）网页的文件大小？

我试过了：

HttpGet request = new HttpGet(fullUrl);

HttpResponse response = new DefaultHttpClient().execute(request);
HttpEntity entity = response.getEntity();

InputStream input = entity.getContent();
int size = input.available();

但是available（）总是返回零。

Answer 1

HttpResponse response = client.execute(httpPost);
String content = EntityUtils.toString(response.getEntity());
byte[] bytes = content.getBytes("UTF8");

URL url = new URL("http://server.com/file.mp3");
URLConnection urlConnection = url.openConnection();
urlConnection.connect();
int file_size = urlConnection.getContentLength();
