Checks if the character is an “hnv-unreserved” character in a SIP-URI.

Examples

iex> Sippet.URI.char_hnv_unreserved?(?:)
true

Checks if the character is an “param-unreserved” character in a SIP-URI.

Examples

iex> Sippet.URI.char_param_unreserved?(?~)
false

Checks if the character is an “unreserved” character in a SIP-URI.

Examples

iex> Sippet.URI.char_unreserved?(?~)
true

Returns the default port for a given SIP scheme. If the scheme is unknown to the Sippet.URI module, this function returns nil.

Examples

iex> Sippet.URI.default_port("sip")
5060
iex> Sippet.URI.default_port("ponzi")
nil

Encodes an enumerable into a “headers” string.

Takes an enumerable that enumerates as a list of two-element tuples (e.g., a map or a keyword list) and returns a string in the form of ?key1=value1&key2=value2... where keys and values are encoded as per encode_header/1. Keys and values can be any term that implements the String.Chars protocol, except lists which are explicitly forbidden.

Examples

iex> hd = %{"foo" => 1, "bar" => 2}
iex> Sippet.URI.encode_headers(hd)
"?bar=2&foo=1"
iex> headers = %{"key" => "value with spaces"}
iex> Sippet.URI.encode_headers(headers)
"?key=value%20with%20spaces"
iex> Sippet.URI.encode_headers %{key: [:a, :list]}
** (ArgumentError) encode_headers/1 values cannot be lists, got: [:a, :list]

Encodes a string as “hname” / “hvalue”.

Example

iex> Sippet.URI.encode_hnvchar("put: it+й")
"put:%20it%2B%D0%B9"

Encodes a string as “paramchar”.

Example

iex> Sippet.URI.encode_paramchar("put: it+й")
"put:%20it%2B%D0%B9"

Encodes an enumerable into a “uri-parameters” string.

Takes an enumerable that enumerates as a list of two-element tuples (e.g., a map or a keyword list) and returns a string in the form of ;key1=value1;key2=value2... where keys and values are encoded as per encode_paramchar/1. Keys and values can be any term that implements the String.Chars protocol, except lists which are explicitly forbidden.

Examples

iex> hd = %{"foo" => 1, "bar" => 2}
iex> Sippet.URI.encode_parameters(hd)
";bar=2;foo=1"
iex> parameters = %{"key" => "value with spaces"}
iex> Sippet.URI.encode_parameters(parameters)
";key=value%20with%20spaces"
iex> Sippet.URI.encode_parameters %{key: [:a, :list]}
** (ArgumentError) encode_parameters/1 values cannot be lists, got: [:a, :list]

Returns a stream of two-element tuples representing key-value pairs in the given headers.

Key and value in each tuple will be binaries and will be percent-unescaped.

Examples

iex> Sippet.URI.headers_decoder("?foo=1&bar=2") |> Enum.to_list()
[{"foo", "1"}, {"bar", "2"}]

Returns a stream of two-element tuples representing key-value pairs in the given parameters.

Key and value in each tuple will be binaries and will be percent-unescaped.

Examples

iex> Sippet.URI.parameters_decoder(";foo=1;bar=2") |> Enum.to_list()
[{"foo", "1"}, {"bar", "2"}]

Parses a well-formed SIP-URI reference into its components.

Note this function expects a well-formed SIP-URI and does not perform any validation. See the “Examples” section below for examples of how Sippet.URI.parse/1 can be used to parse a wide range of URIs. When a SIP-URI is given without a port, the value returned by Sippet.URI.default_port/1 for the SIP-URI’s scheme is used for the :port field. If a %Sippet.URI{} struct is given to this function, this function returns it unmodified.

Examples

iex> Sippet.URI.parse("sip:user@host?Call-Info=%3Chttp://www.foo.com%3E&Subject=foo")
{:ok, %Sippet.URI{scheme: "sip", userinfo: "user", authority: "user@host",
            host: "host", port: 5060, parameters: nil,
            headers: "?Call-Info=%3Chttp://www.foo.com%3E&Subject=foo"}}
iex> Sippet.URI.parse("sip:user@host;transport=FOO")
{:ok, %Sippet.URI{scheme: "sip", userinfo: "user", authority: "user@host",
            host: "host", port: 5060, parameters: ";transport=FOO",
            headers: nil}}
iex> Sippet.URI.parse("sip:user@host")
{:ok, %Sippet.URI{scheme: "sip", userinfo: "user", authority: "user@host",
            host: "host", port: 5060, parameters: nil,
            headers: nil}}

Parses a well-formed SIP-URI reference into its components.

If invalid, raises an exception.

Decodes an encoded string, transforming any percent encoding back to corresponding characters.

Examples

iex> Sippet.URI.percent_unescape("%3Call%20in%2F")
"<all in/"

Returns the string representation of the given Sippet.URI struct.

Examples

iex> Sippet.URI.to_string(Sippet.URI.parse("sip:foo@bar.com"))
"sip:foo@bar.com"
iex> Sippet.URI.to_string(%URI{scheme: "foo", host: "bar.baz"})
"foo:bar.baz"
