io.pedestal.http.route — io.pedestal/pedestal.route 0.5.5

decode-query-part clj

(decode-query-part string)

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

encode-query-part clj

(encode-query-part string)

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

expand-routes clj

(expand-routes route-spec)

Given a value (the route specification), produce and return a sequence of route-maps -- the expanded routes from the specification.

Ensure the integrity of the sequence of route maps (even if they've already been checked).

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

ExpandableRoutes clj protocol

-expand-routes clj

(-expand-routes expandable-route-spec)

Generate and return the routing table from a given expandable form of routing data.

form-action-for-routes clj

(form-action-for-routes routes & default-options)

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.

method-param clj

(method-param)

(method-param query-param-or-param-path)

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.

parse-param-map clj

(parse-param-map m)

parse-path-params clj

(parse-path-params request)

parse-query-params clj

(parse-query-params request)

parse-query-string clj

(parse-query-string string & options)

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.

path-params-decoder clj

An Interceptor which URL-decodes path parameters.

print-routes clj

(print-routes routes)

Prints route table routes in easier to read format.

query-params clj

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.

router clj

(router spec)

(router spec router-impl-key-or-fn)

Delegating fn for router-specification.

router-implementations clj

RouterSpecification clj protocol

router-spec clj

(router-spec specification router-ctor)

Returns an interceptor which attempts to match each route against a :request in context. For the first route that matches, it will:

• enqueue the matched route's interceptors
• associate the route into the context at :route
• associate a map of :path-params into the :request

If no route matches, returns context with :route nil.

try-routing-for clj

(try-routing-for spec router-type query-string verb)

url-for clj

(url-for route-name & options)

Invokes currently bound contextual linker to generate url based on

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

url-for-routes clj

(url-for-routes routes & default-options)

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.
