io.netty.handler.codec.http.HttpDecoderConfig

所有已实现的接口:

java.lang.Cloneable

public final class HttpDecoderConfig
extends java.lang.Object
implements java.lang.Cloneable

A configuration object for specifying the behaviour of HttpObjectDecoder and its subclasses.

The HttpDecoderConfig objects are mutable to reduce allocation, but also Cloneable in case a defensive copy is needed.

构造器详细资料

HttpDecoderConfig

public HttpDecoderConfig()

方法详细资料

getInitialBufferSize

public int getInitialBufferSize()

setInitialBufferSize

public HttpDecoderConfig setInitialBufferSize(int initialBufferSize)

Set the initial size of the temporary buffer used when parsing the lines of the HTTP headers.

参数:

initialBufferSize - The buffer size in bytes.

返回:

This decoder config.

getMaxInitialLineLength

public int getMaxInitialLineLength()

setMaxInitialLineLength

public HttpDecoderConfig setMaxInitialLineLength(int maxInitialLineLength)

Set the maximum length of the first line of the HTTP header. This limits how much memory Netty will use when parsed the initial HTTP header line. You would typically set this to the same value as setMaxHeaderSize(int).

参数:

maxInitialLineLength - The maximum length, in bytes.

返回:

This decoder config.

getMaxHeaderSize

public int getMaxHeaderSize()

setMaxHeaderSize

public HttpDecoderConfig setMaxHeaderSize(int maxHeaderSize)

Set the maximum line length of header lines. This limits how much memory Netty will use when parsing HTTP header key-value pairs. You would typically set this to the same value as setMaxInitialLineLength(int).

参数:

maxHeaderSize - The maximum length, in bytes.

返回:

This decoder config.

getMaxChunkSize

public int getMaxChunkSize()

setMaxChunkSize

public HttpDecoderConfig setMaxChunkSize(int maxChunkSize)

Set the maximum chunk size. HTTP requests and responses can be quite large, in which case it's better to process the data as a stream of chunks. This sets the limit, in bytes, at which Netty will send a chunk down the pipeline.

参数:

maxChunkSize - The maximum chunk size, in bytes.

返回:

This decoder config.

isChunkedSupported

public boolean isChunkedSupported()

setChunkedSupported

public HttpDecoderConfig setChunkedSupported(boolean chunkedSupported)

Set whether Transfer-Encoding: Chunked should be supported.

参数:

chunkedSupported - if false, then a Transfer-Encoding: Chunked header will produce an error, instead of a stream of chunks.

返回:

This decoder config.

isAllowPartialChunks

public boolean isAllowPartialChunks()

setAllowPartialChunks

public HttpDecoderConfig setAllowPartialChunks(boolean allowPartialChunks)

Set whether chunks can be split into multiple messages, if their chunk size exceeds the size of the input buffer.

参数:

allowPartialChunks - set to false to only allow sending whole chunks down the pipeline.

返回:

This decoder config.

getHeadersFactory

public HttpHeadersFactory getHeadersFactory()

setHeadersFactory

public HttpDecoderConfig setHeadersFactory(HttpHeadersFactory headersFactory)

Set the HttpHeadersFactory to use when creating new HTTP headers objects. The default headers factory is DefaultHttpHeadersFactory.headersFactory().

For the purpose of clone(), it is assumed that the factory is either immutable, or can otherwise be shared across different decoders and decoder configs.

参数:

headersFactory - The header factory to use.

返回:

This decoder config.

isAllowDuplicateContentLengths

public boolean isAllowDuplicateContentLengths()

setAllowDuplicateContentLengths

public HttpDecoderConfig setAllowDuplicateContentLengths(boolean allowDuplicateContentLengths)

Set whether more than one Content-Length header is allowed. You usually want to disallow this (which is the default) as multiple Content-Length headers can indicate a request- or response-splitting attack.

参数:

allowDuplicateContentLengths - set to true to allow multiple content length headers.

返回:

This decoder config.

setValidateHeaders

public HttpDecoderConfig setValidateHeaders(boolean validateHeaders)

Set whether header validation should be enabled or not. This works by changing the configured header factory and trailer factory.

You usually want header validation enabled (which is the default) in order to prevent request-/response-splitting attacks.

参数:

validateHeaders - set to false to disable header validation.

返回:

This decoder config.

getTrailersFactory

public HttpHeadersFactory getTrailersFactory()

setTrailersFactory

public HttpDecoderConfig setTrailersFactory(HttpHeadersFactory trailersFactory)

Set the HttpHeadersFactory used to create HTTP trailers. This differs from setHeadersFactory(HttpHeadersFactory) in that trailers have different validation requirements. The default trailer factory is DefaultHttpHeadersFactory.headersFactory().

For the purpose of clone(), it is assumed that the factory is either immutable, or can otherwise be shared across different decoders and decoder configs.

参数:

trailersFactory - The headers factory to use for creating trailers.

返回:

This decoder config.

public HttpDecoderConfig clone()
