Module Uri

module Uri: sig .. end
Uniform Resource Identifier handling that is RFC3986-compliant.
type t
A single URI that is a compact sequence of characters that identifies an abstract or physical resource.

Core functionality 


val empty : t
The empty (zero length) URI reference. Useful for constructing URIs piece-by-piece.
val compare : t -> t -> int
Comparator ordering by host, scheme, port, userinfo, path, query, and finally fragment. Designed to produce a reasonable sort order.
val equal : t -> t -> bool
equal a b is compare a b = 0.
val pct_encode : ?scheme:string -> ?component:component -> string -> string
Percent-encode a string. The scheme argument defaults to 'http' and the component argument defaults to `Path
val pct_decode : string -> string
Percent-decode a percent-encoded string
val of_string : string -> t
Parse a URI string literal into a URI structure
val to_string : t -> string
Convert a URI structure into a percent-encoded URI string
val resolve : string -> t -> t -> t
Resolve a URI against a default scheme and base URI
val canonicalize : t -> t
Canonicalize a URI according to Sec 6.2.3 "Scheme-Based Normalization". This transform is more aggressive than the standard URI-generic normalization automatically done. In particular, HTTP(S) URIs with empty path components will have their path components set to "/". Some applications like web servers may rely on the distinction between a path-less and a root-path URI to distinguish request URIs (e.g. OPTIONS * vs OPTIONS /).
See also RFC 3986.6.2.3
val make : ?scheme:string ->
       ?userinfo:string ->
       ?host:string ->
       ?port:int ->
       ?path:string ->
       ?query:(string * string list) list -> ?fragment:string -> unit -> t
Make a URI from supplied components. If userinfo or port are supplied without host, an empty host is added. If path is supplied and userinfo, host, or port is also supplied, path is made absolute but not resolved.

Query functions

The query string API attempts to accommodate conventional query string representations (i.e. ?key0=value0&key1=value1) while maximally exposing any meaning in those representations. For example, it is not necessarily the case that / and /? are equivalent to a web server. In the former case, we observe a zero query string whereas in the latter case, we observe a query string with a single key, "" and a zero value. Compare this with /?= which has a single key and a single empty value, "". Additionally, some query functions return lists of values for a key. These list values are extracted from a single key with a comma-separated value list. If a query string has multiple identical keys, you must use Uri.query to retrieve the entirety of the structured query string.

val query : t -> (string * string list) list
Get a query string from a URI
val verbatim_query : t -> string option
Get a verbatim query string from a URI. If the provenance of the URI is a string and its query component has not been updated, this is the literal query string as parsed. Otherwise, this is the composition of Uri.query and Uri.encoded_of_query
val encoded_of_query : ?scheme:string -> (string * string list) list -> string
Make a percent-encoded query string from percent-decoded query tuple
val query_of_encoded : string -> (string * string list) list
Parse a percent-encoded query string into a percent-decoded query tuple
val with_query : t -> (string * string list) list -> t
Replace the query URI with the supplied list. Input URI is not modified
val with_query' : t -> (string * string) list -> t
Replace the query URI with the supplied singleton query list. Input URI is not modified
val get_query_param' : t -> string -> string list option
get_query_param' q key returns the list of values for the key parameter in query q. Note that an empty list is not the same as a None return value. For a query foo, the mapping is: Query keys can be duplicated in the URI, in which case the first one is returned. If you want to resolve duplicate keys, obtain the full result set with Uri.query instead.
val get_query_param : t -> string -> string option
get_query_param q key returns the value found for a key in query q. If there are multiple values for the key, then the first one is returned.
val add_query_param : t -> string * string list -> t
Add a query parameter to the input query URI. Input URI is not modified
val add_query_param' : t -> string * string -> t
Add a query parameter to the input singleton query URI. Input URI is not modified
val add_query_params : t -> (string * string list) list -> t
Add a query parameter list to the input query URI. Input URI is not modified
val add_query_params' : t -> (string * string) list -> t
Add a query singleton parameter list to the input query URI. Input URI is not modified
val remove_query_param : t -> string -> t
Remove a query key from the input query URI. Input URI is not modified, and no error is generated if the key does not already exist in the URI.

Component getters and setters 


val path : t -> string
Get the encoded path component of a URI
val path_and_query : t -> string
Get the encoded path and query components of a URI
val with_path : t -> string -> t
Replace the path URI with the supplied encoded path. If a host is present in the supplied URI, the path is made absolute but not resolved. If the path is empty, the path component is removed. Input URI is not modified
val scheme : t -> string option
Get the scheme component of a URI
val with_scheme : t -> string option -> t
Replace the scheme portion of the URI with the supplied scheme. Input URI is not modified
val userinfo : t -> string option
Get the userinfo component of a URI
val with_userinfo : t -> string option -> t
Replace the userinfo portion of the URI with the supplied string option. If no host is present in the supplied URI, an empty host is added. Input URI is not modified.
val user : t -> string option
Get the username component of a URI
val password : t -> string option
Get the password component of a URI
val with_password : t -> string option -> t
Replace the password portion of the URI with the supplied string option. If no host is present in the supplied URI, an empty host is added. Input URI is not modified.
val host : t -> string option
Get the host component of a URI
val with_host : t -> string option -> t
Replace the host component of the URI. Input URI is not modified.
val host_with_default : ?default:string -> t -> string
Get the host component of a URI, with a default supplied if one is not present
val port : t -> int option
Get the port component of a URI
val with_port : t -> int option -> t
Replace the port component of the URI with the supplied port. If no host is present in the supplied URI, an empty host is added. Input URI is not modified.
val fragment : t -> string option
Get the fragment component of a URI
val with_fragment : t -> string option -> t
Replace the fragment component of a URI with the supplied fragment. Input URI is not modified
