Interface HttpServerResponse

All Superinterfaces:

StreamBase, WriteStream<Buffer>

public interface HttpServerResponse
extends WriteStream<Buffer>

Represents a server-side HTTP response.

An instance of this is created and associated to every instance of HttpServerRequest that.

It allows the developer to control the HTTP response that is sent back to the client for a particular HTTP request.

It contains methods that allow HTTP headers and trailers to be set, and for a body to be written out to the response.

It also allows files to be streamed by the kernel directly from disk to the outgoing HTTP connection, bypassing user space altogether (where supported by the underlying operating system). This is a very efficient way of serving files from the server since buffers do not have to be read one by one from the file and written to the outgoing socket.

It implements WriteStream so it can be used with Pipe to pipe data with flow control.

Method Detail

exceptionHandler

HttpServerResponse exceptionHandler(Handler<Throwable> handler)

Description copied from interface: WriteStream

Set an exception handler on the write stream.

Specified by:

exceptionHandler in interface StreamBase

Specified by:

exceptionHandler in interface WriteStream<Buffer>

Parameters:

handler - the exception handler

Returns:

a reference to this, so the API can be used fluently

setWriteQueueMaxSize

HttpServerResponse setWriteQueueMaxSize(int maxSize)

Description copied from interface: WriteStream

Set the maximum size of the write queue to maxSize. You will still be able to write to the stream even if there is more than maxSize items in the write queue. This is used as an indicator by classes such as Pipe to provide flow control.

The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

Specified by:

setWriteQueueMaxSize in interface WriteStream<Buffer>

Parameters:

maxSize - the max size of the write stream

Returns:

a reference to this, so the API can be used fluently

drainHandler

HttpServerResponse drainHandler(Handler<Void> handler)

Description copied from interface: WriteStream

Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.

The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.

Specified by:

drainHandler in interface WriteStream<Buffer>

Parameters:

handler - the handler

Returns:

a reference to this, so the API can be used fluently

getStatusCode

int getStatusCode()

Returns:

the HTTP status code of the response. The default is 200 representing OK.

setStatusCode

HttpServerResponse setStatusCode(int statusCode)

Set the status code. If the status message hasn't been explicitly set, a default status message corresponding to the code will be looked-up and used.

Returns:

a reference to this, so the API can be used fluently

getStatusMessage

String getStatusMessage()

Returns:

the HTTP status message of the response. If this is not specified a default value will be used depending on what setStatusCode(int) has been set to.

setStatusMessage

HttpServerResponse setStatusMessage(String statusMessage)

Set the status message

Returns:

a reference to this, so the API can be used fluently

setChunked

HttpServerResponse setChunked(boolean chunked)

If chunked is true, this response will use HTTP chunked encoding, and each call to write to the body will correspond to a new HTTP chunk sent on the wire.

If chunked encoding is used the HTTP header Transfer-Encoding with a value of Chunked will be automatically inserted in the response.

If chunked is false, this response will not use HTTP chunked encoding, and therefore the total size of any data that is written in the respone body must be set in the Content-Length header before any data is written out.

An HTTP chunked response is typically used when you do not know the total size of the request body up front.

Returns:

a reference to this, so the API can be used fluently

Returns:

is the response chunked?
