Readme for http-client-0.7.19

[back to package description]

http-client

Full tutorial docs are available at: https://github.com/snoyberg/http-client/blob/master/TUTORIAL.md

An HTTP client engine, intended as a base layer for more user-friendly packages.

This codebase has been refactored from http-conduit.

Note that, if you want to make HTTPS secure connections, you should use http-client-tls in addition to this library.

Below is a series of cookbook recipes. A number of recipes exist elsewhere, including Network.HTTP.Client and Network.HTTP.Conduit. The goal is to expand this list over time.

Proxy environment variable

Use the following approach to get proxy settings from the http_proxy and https_proxy environment variables.

{-# LANGUAGE OverloadedStrings #-}
import Network.HTTP.Client
main :: IO ()
main = do
 let settings = managerSetProxy
 (proxyEnvironment Nothing)
 defaultManagerSettings
 man <- newManager settings
 let req = "http://httpbin.org"
 -- Note that the following settings will be completely ignored.
 { proxy = Just $ Proxy "localhost" 1234
 }
 httpLbs req man >>= print
