Constructor Detail

DefaultLastHttpContent

public DefaultLastHttpContent()

Create a new empty, last HTTP content message.

DefaultLastHttpContent

public DefaultLastHttpContent(ByteBuf content)

Create a new last HTTP content message with the given contents.

DefaultLastHttpContent

@Deprecated
public DefaultLastHttpContent(ByteBuf content,
                                          boolean validateHeaders)

Deprecated. Prefer the DefaultLastHttpContent(ByteBuf) constructor instead, to always have header validation enabled.

Create a new last HTTP content message with the given contents, and optional trailing header validation.

Warning! Setting validateHeaders to false will mean that Netty won't validate & protect against user-supplied header values that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.

DefaultLastHttpContent

public DefaultLastHttpContent(ByteBuf content,
                              HttpHeadersFactory trailersFactory)

Create a new last HTTP content message with the given contents, and trailing headers from the given factory.

DefaultLastHttpContent

public DefaultLastHttpContent(ByteBuf content,
                              HttpHeaders trailingHeaders)

Create a new last HTTP content message with the given contents, and trailing headers.
