Plug v1.7.1 Plug.Parsers.URLENCODED

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.

Summary

Functions

init(opts)

Callback implementation for Plug.Parsers.init/1

parse(conn, arg2, arg3, headers, arg5)

Attempts to parse the connection’s request body given the content-type type, subtype, and its parameters

Functions

Link to this function init(opts)

Callback implementation for Plug.Parsers.init/1.

Link to this function parse(conn, arg2, arg3, headers, arg5)

Attempts to parse the connection’s request body given the content-type type, subtype, and its parameters.

The arguments are:

  • the Plug.Conn connection
  • type, the content-type type (e.g., "x-sample" for the "x-sample/json" content-type)
  • subtype, the content-type subtype (e.g., "json" for the "x-sample/json" content-type)
  • params, the content-type parameters (e.g., %{"foo" => "bar"} for the "text/plain; foo=bar" content-type)

This function should return:

  • {:ok, body_params, conn} if the parser is able to handle the given content-type; body_params should be a map
  • {:next, conn} if the next parser should be invoked
  • {:error, :too_large, conn} if the request goes over the given limit

Callback implementation for Plug.Parsers.parse/5.
