Clojure Ring和Compojure-内容类型为application/json的POST请求不起作用

使用内容类型application/json发送POST请求的正确方法是什么

当我向应用程序发送请求时，我无法检索参数

curl -X POST http://localhost:3000/agents --data '{"name":"verma"}' --header "Content-type:application/json"

我正在使用：

[org.clojure/clojure "1.8.0"]
[compojure "1.5.1"]
[ring/ring-defaults "0.2.1"]]

我的handler.cljs是：

▾|    1 (ns sof.rest.handler
 |    2   (:require [compojure.core :refer :all]
 |    3             [compojure.route :as route]
 |    4             [clojure.data.json :as json]
 |    8             [ring.middleware.defaults :refer [wrap-defaults api-defaults]]))
 |    9
 |   10 (defn json-response [data & [status]]
 |   11   {:status (or status 200)
 |   12    :headers {"Content-Type" "application/json"}
 |   13    :body (json/write-str data)})
 |   14
 |   15 (defroutes app-routes
 |~  16   (POST "/agents" params (println params))
 |   21
~|   22 (def app
~|   23   (wrap-defaults app-routes api-defaults))

这些是我运行CURL命令时记录的参数：

{:ssl-client-cert nil, :remote-addr 0:0:0:0:0:0:0:1, :params {}, :route- 
params {}, :headers {accept */*, user-agent curl/7.54.0, content-type 
application/json, content-length 16, host localhost:3000}, :server-port 
3000, :content-length 16, :form-params {}, :compojure/route [:post 
/agents], :query-params {}, :content-type application/json, :character- 
encoding nil, :uri /agents, :server-name localhost, :query-string nil, 
:body #object[org.eclipse.jetty.server.HttpInput 0x70504fbe 
org.eclipse.jetty.server.HttpInput@70504fbe], :scheme :http, :request- 
method :post}

您可以

slurp

输入流（将其读入字符串）并解析其JSON。大概是这样的：

(POST "/agents" request
  (let [body (json/read-str (slurp (:body request)))]
    (println body)))

但是，您应该使用自动执行此操作。

请参阅：form params键i添加了错误的输出。我刚刚编辑过：）
