java.io.IOException:意外的流结束

Question

使用httpurlconnection编写大型视频文件时出现问题.

java.io.IOException: unexpected end of stream on Connection{192.1.4.55, proxy=DIRECT@ hostAddress=192.1.4.55 cipherSuite=none protocol=http/1.1} (recycle count=0)

响应代码在这里

final InputStream is = connection.getInputStream();
            final ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            final byte[] buffer = new byte[maxBufferSize];
            int bytesRead;
            while ((bytesRead = is.read(buffer, 0, 1024)) != -1) {
                bytes.write(buffer, 0, bytesRead);
            }
            log.log(INFO,
                    format("{0} took {4} ms", url,
                            (currentTimeMillis() - start)));
            String response = new String(bytes.toByteArray());

请使用 BufferedInputStream 和 BufferedOutputStream 缓冲较大文件的数据
