Haskell Spock:如何获取原始请求体

body中的Web.Spock.Action函数应该返回原始请求正文。但是,它似乎并没有这样做:

{-# LANGUAGE OverloadedStrings #-}
module Main where

import Data.Text.Encoding (decodeUtf8)
import Debug.Trace        (trace)
import Web.Spock
import Web.Spock.Config

app :: SpockM () () () ()
app = do
    get root $ text "Hello!"
    post "test" $ do
        b <- body       -- b is always ""!
        text $ trace ("b="++show b) decodeUtf8 b

main :: IO ()
main = do
       spockCfg <- defaultSpockCfg () PCNoDatabase ()
       runSpock 3000 (spock spockCfg app)

curl --data 123123 localhost:3000/test不返回任何内容,trace输出确认b为空字符串。

Spock is running on port 3000
b=""

等效的Scotty应用可以正常运行:

{-# LANGUAGE OverloadedStrings #-}
module Main where

import Data.Text.Lazy.Encoding (decodeUtf8)
import Web.Scotty

main = scotty 3000 $ do
    get "/" $ text "Hello!"
    post "/test" $  do
        b <- body       -- works fine
        text $ decodeUtf8 b

我绝对看不出我做错了什么。任何意见都将受到高度赞赏!

更新:以上示例适用于Spock >= 0.12.0.0
