Clojure的Redis的设定是设置值，而不是价值

Question

我使用下面的代码来设置redis的

(defn save-to-redis[key value] 
    (let [str-value (json/generate-string value)] 
     (redis/with-server {:host "127.0.0.1" :port 6379 :db 0} 
     (redis/set key str-value)))) 

键，但是当我检查值运行redis-设置有串的长度CLI我看到它返回STR-值不STR-值的长度

这我已经剥离下来到：

(defn save-to-redis[key value] 
    (redis/with-server {:host "127.0.0.1" :port 6379 :db 0} 
    (redis/set "foo" "bar"))) 

，当我用“的Redis-CLI>得到富”它响应“3”

我上http://devender.wordpress.com/2010/06/13/redis-and-clojure/看的例子，甚至复制和粘贴他的榜样失败。我尝试：

(defn test-redis [] 
(println "testing redis") 
(redis/with-server {:host "127.0.0.1" :port 6379 :db 0} 
    (do 
    (redis/set "foo" "bar") 
    (println (redis/get "foo"))))) 

，我得到

我在我束手无策。如果它有帮助，这里是我的ns形式：

(ns spendy.core 
    (:use [hiccup core page-helpers]) 
    (:require redis 
     [clj-json.core :as json]))

您使用的是哪个版本的redis-clojure？它的工作原理罚款与此：https://github.com/tavisrudd/redis-clojure

试试这个（从mmcgrana和technomancy - 两个Clojure的大师）。顺便说
