Server
is a HTTP 1.1 server.
type request = Http.Request.t * Eio.Buf_read.t * Eio.Net.Sockaddr.stream
The request headers, a reader for the socket, and the address of the client. To read the request body, use read_fixed
or read_chunked
.
type response = Http.Response.t * Body.t
type 'a env =
< domain_mgr : Eio.Domain_manager.t
; net : Eio.Net.t
; clock : Eio.Time.clock.. > as 'a
val read_fixed : Http.Request.t -> Eio.Buf_read.t -> string option
read_fixed (request, buf_read)
is Some content
, where content
is of length n
if "Content-Length" header is a valid integer value n
in request
.
buf_read
is updated to reflect that n
bytes was read.
If "Content-Length"
header is missing or is an invalid value in request
OR if the request http method is not one of POST
, PUT
or PATCH
, then None
is returned.
val read_chunked :
Http.Request.t ->
Eio.Buf_read.t ->
(Body.chunk -> unit) ->
Http.Header.t option
read_chunked request buf_read chunk_handler
is Some updated_headers
if "Transfer-Encoding" header value is "chunked" in request
and all chunks in buf_read
are read successfully. updated_headers
is the updated headers as specified by the chunked encoding algorithm in https: //datatracker.ietf.org/doc/html/rfc7230#section-4.1.3.
buf_read
is updated to reflect the number of bytes read. Returns None
if Transfer-Encoding
header in headers
is not specified as "chunked"
val text_response : string -> response
text t s
returns a HTTP/1.1, 200 status response with "Content-Type" header set to "text/plain".
val html_response : string -> response
html t s
returns a HTTP/1.1, 200 status response with header set to "Content-Type: text/html".
val not_found_response : response
not_found t
returns a HTTP/1.1, 404 status response.
val internal_server_error_response : response
internal_server_error
returns a HTTP/1.1, 500 status response.
val bad_request_response : response
run ~socket_backlog ~domains ~port env handler
runs a HTTP/1.1 server executing handler
and listening on port
. env
corresponds to Eio.Stdenv.t
.
socket_backlog
is the number of pending connections for tcp server socket. The default is 128
.
domains
is the number of OCaml 5.0 domains the server will use. The default is 1
. You may use Domain.recommended_domain_count
to configure a multicore capable server.
val connection_handler :
handler ->
Eio.Time.clock ->
Eio.Net.stream_socket ->
Eio.Net.Sockaddr.stream ->
unit
connection_handler request_handler
is a connection handler, suitable for passing to Eio.Net.accept_fork
.
val not_found_handler : handler
not_found_handler
return HTTP 404 response.
