tcp-streams

One stop solution for tcp client and server with tls support!

• use io-streams for auto read buffering and easy streamming process.

• use tls for tls connection.

Built-in mozilla CA list date: 2017/06/07.

From v0.6 TLS using HsOpenSSL is split into tcp-streams-openssl due to the difficulties of setting up openssl on many platform.

Also take a look at wire-stream, for serialize/deserialize data. Happy hacking!

Example

import           Data.Connection
import qualified System.IO.Streams.TCP     as TCP
import qualified Data.TLSSetting           as TLS
import qualified System.IO.Streams.TLS     as TLS

--  TCP Client
...
conn <- TCP.connect "127.0.0.1" 8888
send conn "Hello! World." ..  -- sending
res <- Stream.read (source conn) ..  -- receiving
close conn                ..  -- closing
...


-- TCP Server
...
sock <- TCP.bindAndListen 1024 8888
conn <- TCP.accept sock
req <- Stream.read (source conn) ..   -- receiving
send conn "GoodBye!" ..  -- sending
...


--  TLS Client
...
cp <- TLS.makeTLSClientParams (TLS.CustomCAStore "myCA.pem")
conn <- TLS.connect cp (Just "myCAName") "127.0.0.1" 8888
...


--  TLS Server
...
sp <- TLS.makeServerParams "server.crt" [] "server.key"
sock <- TCP.bindAndListen 1024 8889
conn <- TLS.accept sp sock
...


-- HTTPS Client
...
cp <- TLS.makeClientParams TLS.MozillaCAStore
conn <- TLS.connect cp Nothing "www.google.com" 443
send conn "GET / HTTP/1.1\r\n"
send conn "Host: www.google.com\r\n"
send conn "\r\n"
bs <- Stream.readExactly 1024 (source conn)
...
