使用ring format-params中间件访问已发布的json [英] Accessing posted json with ring format-params middleware

问题描述

我想在clojure中使用一个非常简单的API。我使用rack.middleware.format-params中间件将输出转换为json，并将输入从json转换为clojure数据结构。

I'm trying to make a very simple API using ring in clojure. I'm using the rack.middleware.format-params middleware to convert the output to json, and the input from json to clojure data structures.

我有输出工作很好，但我不能为我的生活访问通过json发送的参数。下面是一些适用于get请求的代码，但是我不能获取POST请求来返回它接收到的json

I've got the output working nicely, but I can't for the life of me access the parameters sent through json. Here's some code that works for get requests, but I can't get the POST request to return the json it recieves

(ns testing.core
  (:use [compojure.core]
        [ring.middleware.format-params :only [wrap-json-params]]
        [ring.middleware.format-response :only [wrap-json-response]]
        [ring.adapter.jetty])
  (:require [compojure.handler :as handler]))

(defroutes app-routes
  (GET "/"
       []
       {:body {:hello "world"}})

  (POST "/"
        {params :params}
        {:body params}))

(def app
  (-> (handler/api app-routes)
      (wrap-json-params)
      (wrap-json-response)))

{}

我做错了什么？

推荐答案

我是一个白痴，意识到，我没有发送json Content-Type头。希望没有人会犯同样的错误：P

I'm an idiot and realised that I wasn't sending the json Content-Type header. Hopefully no-one else makes the same silly mistake :P
