# http_uri

### MODULE

http_uri

### MODULE SUMMARY

URI utility module

### DESCRIPTION

This module provides utility functions for working with URIs, according to RFC 3986.

### COMMON DATA TYPES

Type definitions that are used more than once in this module:

    boolean() = true | false
    string()  = list of ASCII characters

### URI DATA TYPES

Type definitions that are related to URI:

For more information about URI, see RFC 3986.

    uri()       = string() - Syntax according to the URI definition in rfc 3986, ex: "http://www.erlang.org/"
    user_info() = string()
    scheme()    = atom()   - Example: http, https
    host()      = string()
    port()      = pos_integer()
    path()      = string() - Representing a file path or directory path
    query()     = string()

### EXPORTS

scheme_defaults() -> SchemeDefaults

Types:

SchemeDefaults = [{scheme(), default_scheme_port_number()}]
default_scheme_port_number() = pos_integer()

This function provides a list of the scheme and their default port numbers currently supported (by default) by this utility.

parse(URI) -> {ok, Result} | {error, Reason}
parse(URI, Options) -> {ok, Result} | {error, Reason}

Types:

URI = uri()
Options = [Option]
Option = {ipv6_host_with_brackets, boolean()} | {scheme_defaults, scheme_defaults()}]
Result = {Scheme, UserInfo, Host, Port, Path, Query}
UserInfo = user_info()
Host = host()
Port = pos_integer()
Path = path()
Query = query()
Reason = term()

This function is used to parse an URI. If no scheme defaults are provided, the value of scheme_defaults function will be used.

Note that when parsing an URI with an unknown scheme (that is, a scheme not found in the scheme defaults) a port number must be provided or else the parsing will fail.

encode(URI) -> HexEncodedURI

Types:

URI = uri()
HexEncodedURI = string() - Hex encoded uri

Hex encode an URI.

decode(HexEncodedURI) -> URI

Types:

HexEncodedURI = string() - A possibly hex encoded uri
URI = uri()

Decode a possibly hex encoded URI.
