Feature / BC break: The
Request
andResponse
objects now follow strict
stream semantics and their respective methods and events.
(#116, #129, #133, #135, #136, #137, #138, #140, #141 by @legionth
and #122, #123, #130, #131, #132, #142 by @clue)This implies that the
Server
now supports proper detection of the request
message body stream, such as supporting decoding chunked transfer encoding,
delimiting requests with an explicitContent-Length
header
and those with an empty request message body.These streaming semantics are compatible with previous Stream v0.5, future
compatible with v0.5 and upcoming v0.6 versions and can be used like this:$http->on('request', function (Request $request, Response $response) { $contentLength = 0; $request->on('data', function ($data) use (&$contentLength) { $contentLength += strlen($data); }); $request->on('end', function () use ($response, &$contentLength){ $response->writeHead(200, array('Content-Type' => 'text/plain')); $response->end("The length of the submitted request body is: " . $contentLength); }); // an error occured // e.g. on invalid chunked encoded data or an unexpected 'end' event $request->on('error', function (\Exception $exception) use ($response, &$contentLength) { $response->writeHead(400, array('Content-Type' => 'text/plain')); $response->end("An error occured while reading at length: " . $contentLength); }); });
Similarly, the
Request
andResponse
now strictly follow the
close()
method andclose
event semantics.
Closing theRequest
does not interrupt the underlying TCP/IP in
order to allow still sending back a valid response message.
Closing theResponse
does terminate the underlying TCP/IP
connection in order to clean up resources.You should make sure to always attach a
request
event listener
like above. TheServer
will not respond to an incoming HTTP
request otherwise and keep the TCP/IP connection pending until the
other side chooses to close the connection. -
Feature: Support
HTTP/1.1
andHTTP/1.0
forRequest
andResponse
.
(#124, #125, #126, #127, #128 by @clue and #139 by @legionth)The outgoing
Response
will automatically use the same HTTP version as the
incomingRequest
message and will only applyHTTP/1.1
semantics if
applicable. This includes that theResponse
will automatically attach a
Date
andConnection: close
header if applicable.This implies that the
Server
now automatically responds with HTTP error
messages for invalid requests (status 400) and those exceeding internal
request header limits (status 431).
