Decodes one key or value of URL-encoded UTF-8 characters in a URL query string.

Encodes one key or value for a UTF-8 URL-encoded query string. Encodes space as +.

Given a value (the route specification), produce and return a routing table, a seq of verbose routing maps.

A route specification is any type that satisfies ExpandableRoutes; this includes Clojure vectors, maps, and sets (for terse, table, and verbose routes).

Ensures the integrity of expanded routes (even if they’ve already been checked):

• Constraints are correctly ordered (most specific to least specific)
• Route names are unique

A protocol extended onto types that can be used to convert instances into a seq of verbose route maps, the routing table.

Built-in implementations map vectors to terse-routes, sets to table-routes, and maps to map-routes->vec-routes.

Like ‘url-for-routes’ but the returned function returns a map with the keys :action, the URL string; and :method, the HTTP verb as a lower-case string. Also, the :method-param is :_method by default, so HTTP verbs other than GET and POST will be converted to POST with the actual verb in the query string.

Returns an interceptor that smuggles HTTP verbs through a value in the request. Must come after the interceptor that populates that value (e.g. query-params or body-params).

query-param-or-param-path may be one of two things:

• The parameter inside :query-params where the verb will reside.
• A complete path to a value elsewhere in the request, such as :query-params :_method or :body-params “_method”

The path :query-params :_method is used by default.

Parses URL query string (not including the leading ‘?’) into a map. options are key-value pairs, valid options are:

:key-fn Function to call on parameter keys (after URL decoding), returns key for the map, default converts to a keyword.

:value-fn Function to call on the key (after passing through key-fn) and parameter value (after URL decoding), returns value for the map, default does nothing.

An Interceptor which URL-decodes path parameters. The path parameters are in the :request map as :path-parameters.

This will only operate once per interceptor chain execution, even if it appears multiple times; this prevents failures in existing applications that upgrade to Pedestal 0.6.0, as prior releases incorrectly failed to parse path parameters. Existing applications that upgrade may have this interceptor in some routes, which could yield runtime exceptions and request failures if the interceptor is executed twice.

Prints a route table (from expand-routes) in an easier to read format.

Returns an interceptor which parses query-string parameters from an HTTP request into a map. Keys in the map are query-string parameter names, as keywords, and values are strings. The map is assoc’d into the request at :query-params.

Given the routing table and, optionally, what kind of router to construct, returns a RouterSpecification instance, from which a routing interceptor can be obtained.

router-type may be a keyword identifying a known router-implementation, or function that accepts a routing table, and returns a Router.

The default router type is :map-tree, which is the fastest built-in router; however, if the expanded routes contain path paramters or wildcards, the result is equivalent to the slower :prefix-tree implementation.

Maps from the common router implemenations (:map-tree, :prefix-tree, or :linear-search) to a router constructor function (which accepts expanded routes, and returns a Router instance).

Used for testing; constructs a router from the routing-table and router-type and perform routing, returning the matched route (from the expanded routes), or nil if routing was unsuccessful.

Invokes currently bound contextual linker to generate url based on

• The routing table in use.
• The incoming request being routed.

where options are as described in url-for-routes.

Returns a function that generates URL routes (as strings) from the routes table. The returned function has the signature:

route-name & options

Where ‘options’ are key-value pairs from:

:app-name Application name specified for this route

:request The original request; it will be merged into the generated link.

:params A map of all parameters; any params not used as path parameters will be added to the query string

:path-params A map of path parameters only

:strict-path-params? A boolean, when true will throw an exception if all path-params aren’t fulfilled for the url

:query-params A map of query-string parameters only

:method-param Keyword naming the query-string parameter in which to place the HTTP method name, if it is neither GET nor POST. If nil, the HTTP method name will not be included in the query string. Default is nil.

:context A string, function that returns a string, or symbol that resolves to a function that returns a string that specifies a root context for the URL. Default is nil.

:fragment A string for the fragment part of the url.

:absolute? Boolean, whether or not to force an absolute URL

:scheme Keyword (:http | :https) used to override the scheme portion of the url.

:host A string used to override the host portion of the URL.

:port An integer used to override the port in the URL.

In addition, you may supply default-options to the ‘url-for-routes’ function, which are merged with the options supplied to the returned function.
