如何使用Haskell'；s Network.HTTP.Req库？,http,haskell,Http,Haskell,我试图执行一个简单的HTTPGET请求，但我得到了一个404。我假设URL上有问题，但我找不到以下是执行请求的函数： getMockResource :: (MonadHttp m) => m BsResponse getMockResource = req GET (http "www.mocky.io" /: "/v2/5da208d92f00007900f418ff") NoReqBody bsResponse mempty 我的主要意见是： main :

我试图执行一个简单的HTTPGET请求，但我得到了一个404。我假设URL上有问题，但我找不到

以下是执行请求的函数：

getMockResource :: (MonadHttp m) =>  m BsResponse 
getMockResource = req
  GET
  (http "www.mocky.io" /: "/v2/5da208d92f00007900f418ff")
  NoReqBody
  bsResponse
  mempty

我的主要意见是：

main :: IO ()
main = runReq defaultHttpConfig $ do
  r <- getMockResource
  liftIO $ B.putStrLn (responseBody r)

main:：IO（）
main=runReq defaultHttpConfig$do
r路径在此转义。要使用斜杠，可以使用：
getMockResource:：MonadHttp m=>BSM响应
getMockResource=req
得到
（http“www.mocky.io”/：“v2”/“5da208d92f00007900f418ff”）

BSR响应
mempty
感谢的提示，我仔细查看了URL创建，需要
http“www.mocky.io”/：“v2”/：“5da208d92f00007900f418ff”

而不是：
（http“www.mocky.io”/v2/5da208d92f0007900f418ff）
路径在此处转义。注意/%2F等。
