Constructor Detail

HttpDecoderSpec

public HttpDecoderSpec()

Method Detail

maxInitialLineLength

public T maxInitialLineLength(int value)

Configure the maximum length that can be decoded for the HTTP request's initial line. Defaults to DEFAULT_MAX_INITIAL_LINE_LENGTH.

Parameters:

value - the value for the maximum initial line length (strictly positive)

Returns:

this option builder for further configuration

maxInitialLineLength

public int maxInitialLineLength()

Return the configured maximum length that can be decoded for the HTTP request's initial line.

Returns:

the configured maximum length that can be decoded for the HTTP request's initial line

maxHeaderSize

public T maxHeaderSize(int value)

Configure the maximum header size that can be decoded for the HTTP request. Defaults to DEFAULT_MAX_HEADER_SIZE.

Parameters:

value - the value for the maximum header size (strictly positive)

Returns:

this option builder for further configuration

maxHeaderSize

public int maxHeaderSize()

Return the configured maximum header size that can be decoded for the HTTP request.

Returns:

the configured maximum header size that can be decoded for the HTTP request

maxChunkSize

@Deprecated
public T maxChunkSize(int value)

Deprecated. as of 1.1.0. This will be removed in 2.0.0 as Netty 5 does not support this configuration.

Configure the maximum chunk size that can be decoded for the HTTP request. Defaults to DEFAULT_MAX_CHUNK_SIZE.

Parameters:

value - the value for the maximum chunk size (strictly positive)

Returns:

this option builder for further configuration

maxChunkSize

@Deprecated
public int maxChunkSize()

Deprecated. as of 1.1.0. This will be removed in 2.0.0 as Netty 5 does not support this configuration.

Return the configured maximum chunk size that can be decoded for the HTTP request.

Returns:

the configured maximum chunk size that can be decoded for the HTTP request

validateHeaders

public T validateHeaders(boolean validate)

Configure whether to validate headers when decoding requests. Defaults to DEFAULT_VALIDATE_HEADERS.

Parameters:

validate - true to validate headers, false otherwise

Returns:

this option builder for further configuration

validateHeaders

public boolean validateHeaders()

Return the configuration whether to validate headers when decoding requests.

Returns:

the configuration whether to validate headers when decoding requests

initialBufferSize

public T initialBufferSize(int value)

Configure the initial buffer size for HTTP request decoding. Defaults to DEFAULT_INITIAL_BUFFER_SIZE.

Parameters:

value - the initial buffer size to use (strictly positive)

Returns:

this option builder for further configuration

initialBufferSize

public int initialBufferSize()

Return the configured initial buffer size for HTTP request decoding.

Returns:

the configured initial buffer size for HTTP request decoding

allowDuplicateContentLengths

public T allowDuplicateContentLengths(boolean allow)

Configure whether to allow duplicate Content-Length headers. Defaults to DEFAULT_ALLOW_DUPLICATE_CONTENT_LENGTHS which means that a message with duplicate Content-Length headers is rejected. When this is configured to true, duplicate Content-Length headers are accepted only if they are all the same value, otherwise such message is rejected. The duplicated Content-Length headers are replaced with a single valid Content-Length header.

Parameters:

allow - true to allow duplicate Content-Length headers with the same value, false otherwise

Returns:

this option builder for further configuration

Since:

1.0.8

allowDuplicateContentLengths

public boolean allowDuplicateContentLengths()

Return the configuration whether to allow duplicate Content-Length headers.

Returns:

the configuration whether to allow duplicate Content-Length headers

Since:

1.0.8

h2cMaxContentLength

public T h2cMaxContentLength(int h2cMaxContentLength)

Configure the maximum length of the content of the HTTP/2.0 clear-text upgrade request.

• By default the server will reject an upgrade request with non-empty content, because the upgrade request is most likely a GET request. If the client sends a non-GET upgrade request, h2cMaxContentLength specifies the maximum length of the content of the upgrade request.
• By default the client will allow an upgrade request with up to 65536 as the maximum length of the aggregated content.

Parameters:

h2cMaxContentLength - the maximum length of the content of the upgrade request

Returns:

this builder for further configuration

h2cMaxContentLength

public int h2cMaxContentLength()

Return the configured maximum length of the content of the HTTP/2.0 clear-text upgrade request.

Returns:

the configured maximum length of the content of the HTTP/2.0 clear-text upgrade request

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
