The uri-common library provides simple and easy-to-use parsing and manipulation procedures for URIs using common schemes.
These "common schemes" all have the following rules:
- An empty path after the hostname is considered to be identical to the root path.
- All components are to be fully URI-decoded (so no percent-encoded characters in it).
- The query argument will be in application/x-www-form-urlencoded form.
- The port is automatically determined if it is omitted and the URI scheme is known.
Constructors[procedure] (uri-common-reference string) => uri-common
[procedure] (absolute-uri-common string) => uri-common
Construct a new uri-common object, analogous to uri-reference and absolute-uri from uri-generic.
uri-generic and string representation[procedure] (uri-common->uri-generic uri-common) => uri-generic
[procedure] (uri-generic->uri-common uri-common) => uri-common
To convert between uri-generic and uri-common objects, use these procedures.[procedure] (uri-common->string uri-common userinfo) => string
Reconstructs the given URI into a string; uses a supplied function LAMBDA USERNAME PASSWORD -> STRING to map the userinfo part of the URI
Predicates and Accessors
- <procedure>(uri-common? uri-common) => bool</procedure>
- <procedure>(uri-common-scheme uri-common) => symbol</procedure>
- <procedure>(uri-common-path uri-common) => list</procedure>
- <procedure>(uri-common-query uri-common) => alist</procedure>
- <procedure>(uri-common-fragment uri-common) => string</procedure>
- <procedure>(uri-common-host uri-common) => string</procedure>
- <procedure>(uri-common-port uri-common) => integer</procedure>
- <procedure>(uri-common-username uri-common) => string</procedure>
- <procedure>(uri-common-password uri-common) => string</procedure>
If a component is not defined in the given URI-common, then the corresponding accessor returns #f.
- <procedure>(update-uri-common URI-common #!key scheme path query fragment host port username password) => URI-common</procedure>
Update the specified keys in the URI-common object in a functional way (ie, it creates a new copy with the modifications).
Reference Resolution[procedure] (uri-common-relative-to URI URI) => URI
Constructs an absolute URI given a relative URI and a base URI (RFC 3986, Section 5.2.2)[procedure] (uri-common-relative-from URI URI) => URI
Constructs a new, possibly relative, URI which represents the location of the first URI with respect to the second URI.
Query encoding and decoding
- <parameter>(form-urlencoded-separator [char-set/char/string])</parameter>
- <procedure>(form-urlencode alist #!key (separator (form-urlencoded-separator))) => string</procedure>
- <procedure>(form-urldecode string #!key (separator (form-urlencoded-separator))) => alist</procedure>
Encode or decode an alist using the encoding corresponding to the form-urlencoded media type, using the given separator character(s).
When encoding, if separator is a string, the first character will be used as the separator in the resulting querystring. If it is a char-set, it will be converted to a string and its first character will be taken. In either case, all of these characters are encoded if they occur inside the key/value pairs.
When decoding, any character in the set (or string) will be seen as a separator.
The separator defaults to the string ";&". This means that ampersands are allowed as separators, but semicolons are preferred, and generated URI string always contain semicolons as separators.
Normalization[procedure] (uri-common-normalize-case URI) => URI
