defmodule Plug.Parsers.URLENCODED do

@moduledoc """
|

|
|
Parses urlencoded request body.
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
All options supported by `Plug.Conn.read_body/2` are also supported here.
|
||
|
|
They are repeated here for convenience:
|
||
|
|
|
||
|
|
* `:length` - sets the maximum number of bytes to read from the request,
|
||
|
|
defaults to 1_000_000 bytes
|
||
|
|
* `:read_length` - sets the amount of bytes to read at one time from the
|
||
|
|
underlying socket to fill the chunk, defaults to 1_000_000 bytes
|
||
|
|
* `:read_timeout` - sets the timeout for each socket read, defaults to
|
||
|
|
15_000ms
|
||
|
|
|
||
|
|
So by default, `Plug.Parsers` will read 1_000_000 bytes at a time from the
|
||
|
|
socket with an overall limit of 8_000_000 bytes.
