public class HttpRequestDecoder extends HttpMessageDecoder
DecodesChannelBuffer
s intoHttpRequest
s andHttpChunk
s.Parameters that prevents excessive memory consumption
Name Meaning maxInitialLineLength
The maximum length of the initial line (e.g. "GET / HTTP/1.0"
) If the length of the initial line exceeds this value, aTooLongFrameException
will be raised.maxHeaderSize
The maximum length of all headers. If the sum of the length of each header exceeds this value, a TooLongFrameException
will be raised.maxChunkSize
The maximum length of the content or each chunk. If the content length exceeds this value, the transfer encoding of the decoded request will be converted to 'chunked' and the content will be split into multiple HttpChunk
s. If the transfer encoding of the HTTP request is 'chunked' already, each chunk will be split into smaller chunks if the length of the chunk exceeds this value. If you prefer not to handleHttpChunk
s in your handler, insertHttpChunkAggregator
after this decoder in theChannelPipeline
