问题 I am am trying to setup LevelDB in a ring/compojure app, and looking for an idiomatic way to to access the opened db descriptor into each request. For example: (defn -main "I don't do a whole lot ... yet." [& args] (println "Opening LevelDB file in db/main") (with-open [main-db (db/open "db/main")] (println "Running server on port 3000") (run-jetty #'web/app {:port 3000}))) How do you access the main-db descriptor into the request handlers? ie.: (defroutes handler (GET "/test" [] (db/put main

问题 I am configuring and setting up a web application to serve the JSON data http://www.ericrochester.com/clj-data-analysis/data/census-race.json file statically. My dependencies: :dependencies [[org.clojure/clojure "1.5.1"] [org.clojure/clojurescript "0.0-2197"] [ring/ring-core "1.1.7"] [ring/ring-jetty-adapter "1.1.7"] [compojure "1.1.3"] [hiccup "1.0.2"] [lein-cljsbuild "0.2.10"]] As the title says I'm using Ring as a development plugin, i.e. :plugins [[lein-ring "0.8.3"]] The Leiningen

问题 I think I have a fairly straightforward problem here. But I've been looking at this screen too long. So I'm trying (and failing) to get stateful sessions working in Compojure. The refheap code paste is here . You can see me trying to use lib-noir (line 62) to initialize stateful sessions. Then when the app is running, I try to make a call to session/put! some data in the session (line 43). Now, this stacktrace says that in session.put!, lib-noir is trying to swap out a session var that hasn't

问题 In Clojure / Compojure, how do I convert a map to a URL query string? {:foo 1 :bar 2 :baz 3} to foo=1&bar=2&baz=3 Is there any utility method to do this in compojure? 回答1: Yes, there is a utility for this already that doesn't involve Hiccup or rolling your own string/join/URLEncoder function: user=> (ring.util.codec/form-encode {:foo 1 :bar 2 :baz 3}) "foo=1&bar=2&baz=3" user=> Compojure depends on ring/ring-core, which includes ring.util.codec, so you already have it. 回答2: Something like:

问题 How does one inject state into ring handlers most conveniently (without using global vars)? Here is an example: (defroutes main-routes (GET "/api/fu" [] (rest-of-the-app the-state))) (def app (-> (handler/api main-routes))) I would like to get the-state into the compojure handler for main-routes . The state might be something like a map created with: (defn create-app-state [] {:db (connect-to-db) :log (create-log)}) In a non ring application I would create the state in a main function and

问题 Update : this question has changed since the original set of commenters left responses. Apologies for any confusion. This is my code repository https://github.com/Integralist/spurious-clojure-example you can use it as an example for what I'm working with. Note that the above repo relies on a library I've not yet published to Clojars (as I'm still testing it - hence this question opened). You can see the source code of the library here: https://github.com/Integralist/spurious-clojure-aws-sdk

问题 I'm writing a Compojure application and am using clj-webdriver to graphically test it. I'm trying to use with-redefs to mock out the function that pulls out data from persistence to just return canned values, but it's ignoring my function overwrite. I know with-redefs works in terms of vars, but it's still not working: project.clj relevant pieces: (defproject run-hub "0.1.0-SNAPSHOT" :main run-hub.handler/start-server) handler.clj: (ns run-hub.handler (:require [compojure.core :refer :all]

问题 I am writing a small website in Clojure and Compojure. I would like to set the HTTP response status for each request based on the data found or not found. The last call is the html5 macro that returns to the handler the html that needs to be sent back to the browser. Is it possible to set the HTTP response status somehow here? (ns myapp.views.layout (:require [hiccup.page :refer (html5 include-css include-js)])) (defn layout [title & content] (html5 (head title) (body content))) 回答1: If you

问题 My code: (defn json-response [data & [status]] {:status (or status 200) :headers {"Content-Type" "application/json"} :body (json/generate-string data)}) (defroutes checkin-app-handler (GET "/:code" [code & more] (json-response {"code" code "params" more}))) When I load the file to the repl and run this command, the params seems to be blank: $ (checkin-app-handler {:server-port 8080 :server-name "127.0.0.1" :remote-addr "127.0.0.1" :uri "/123" :query-string "foo=1&bar=2" :scheme :http :headers
