ByteString.read介绍

[英]Reads count bytes from in and returns the result.
[中]从中读取计数字节并返回结果。

代码示例

private Optional<ByteString> readPayload(HttpServletRequest req, int contentLength) throws IOException {
 final InputStream input = new BufferedInputStream(req.getInputStream());
 if (contentLength < 0) {
  // contentLength = -1 may be returned when using Transfer-Encoding: chunked
  // (RFC 7230, section 3.3.1: Transfer-Encoding) even though data is being transferred in a series of chunks.
  // In that case try read this data before concluding that there is no payload.
  final ByteString byteString = ByteString.of(ByteStreams.toByteArray(input));
  return byteString.size() == 0 ? Optional.empty() : Optional.of(byteString);
 } else {
  return Optional.of(ByteString.read(input, contentLength));
 }
}
