解决Network.HTTP'用户错误(不支持https)' [英] Resolving Network.HTTP 'user error (https not supported)'

问题描述

使用 runghc 运行此Haskell程序时:

When running this Haskell program using runghc:

import Network.HTTP

main = simpleHTTP (getRequest "https://stackoverflow.com")
       >>= getResponseBody >>= putStrLn

我收到错误消息

printso.hs: user error (https not supported)

我不想切换到未加密的HTTP，如何使用 Network.HTTP 具有SSL/TLS?

I don't want to switch to unencrypted HTTP -- how can I use Network.HTTP with SSL/TLS?

推荐答案

您不能直接这样做，例如，请参见 Network.代替来自 http-conduit 库的HTTP.Conduit .

You can't do that directly, see for example this post. However you could use Network.HTTP.Conduit from the http-conduit library instead.

首先使用 cabal install http-conduit 进行安装.

然后，您可以使用以下代码(请注意，它与 Network.HTTP 相对，它使用了懒惰的 ByteString s)代替:

Then you can use this code (note that it contrast to Network.HTTP it uses lazy ByteStrings) as a replacement:

import Network.HTTP.Conduit
import qualified Data.ByteString.Lazy as LB

main = simpleHttp "https://stackoverflow.com"
       >>= LB.putStr

另一种替代方法是使用 Haskell libcurl 绑定，具体取决于但是，在本地 libcurl 上.

Another alternative is to use the Haskell libcurl binding which depends on the native libcurl, however.
