}

A request with method, path, host, headers, and a body, sent by a client.

The body is polymorphic because the request goes through several transformations. First it has no body, as only the request and headers are read; then it has a stream body; then the body might be entirely read as a string via read_body_full.

since 0.6 The field [query] was added and contains the query parameters in ["?foo=bar,x=y"]

since 0.6 The field [path_components] is the part of the path that precedes [query] and is split on ["/"].

since 0.11 the type is a private alias

since 0.11 the field [start_time] was added

val pp : Format.formatter -> string t -> unit

Pretty print the request and its body. The exact format of this printing is not specified.

val pp_ : Format.formatter -> _ t -> unit

Pretty print the request without its body. The exact format of this printing is not specified.

val headers : _ t -> Headers.t

List of headers of the request, including "Host".

val get_header : ?f:(string -> string) -> _ t -> string -> string option

get_header req h looks up header h in req. It returns None if the header is not present. This is case insensitive and should be used rather than looking up h verbatim in headers.

val get_header_int : _ t -> string -> int option

Same as get_header but also performs a string to integer conversion.

val set_header : string -> string -> 'a t -> 'a t

set_header k v req sets k: v in the request req's headers.

val update_headers : (Headers.t -> Headers.t) -> 'a t -> 'a t

Modify headers using the given function.

since 0.11

val set_body : 'a -> _ t -> 'a t

set_body b req returns a new query whose body is b.

since 0.11

val host : _ t -> string

Host field of the request. It also appears in the headers.

val client_addr : _ t -> Unix.sockaddr

Client address of the request.

since 0.16

val meth : _ t -> Meth.t

Method for the request.

val path : _ t -> string

Request path.

val query : _ t -> (string * string) list

Decode the query part of the path field.

since 0.4

val body : 'b t -> 'b

Request body, possibly empty.

val start_time : _ t -> float

time stamp (from Unix.gettimeofday) after parsing the first line of the request

since 0.11

val limit_body_size : max_size:int -> byte_stream t -> byte_stream t

Limit the body size to max_size bytes, or return a 413 error.

since 0.3

val read_body_full : 
  ?buf:Tiny_httpd_buf.t ->
  ?buf_size:int ->
  byte_stream t ->
  string t

Read the whole body into a string. Potentially blocking.

parameter buf_size
initial size of underlying buffer (since 0.11)

parameter buf
the initial buffer (since 0.14)
