# Connect Proxy

[![CI](https://github.com/spider-gazelle/connect-proxy/actions/workflows/ci.yml/badge.svg)](https://github.com/spider-gazelle/connect-proxy/actions/workflows/ci.yml)

A simple implementation of the [connect method](https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_method) for HTTP tunnelling.

Most commonly used in [HTTP proxy servers](https://en.wikipedia.org/wiki/Proxy_server#Web_proxy_servers).

# Usage

The most common usage of this shard is to use the crystal `::HTTP::Client` via a proxy server

```crystal

host = URI.parse("https://www.google.com")

response = ConnectProxy::HTTPClient.new(host) do |client|

  client.exec("GET", "/")

end

response.success?

```

By default the HTTP client will pick up the `https_proxy` or `http_proxy` environment variables and use the URLs configured in there.

However you can override the environment or provide your own proxy server.

```crystal

host = URI.parse("https://www.google.com")

client = ConnectProxy::HTTPClient.new(host)

proxy = ConnectProxy.new("134.209.219.234", 80, {username: "admin", password: "pass"})

client.set_proxy(proxy)

response = client.exec("GET", "/")

response.success?

```

## Forcing Proxy Support

It's possible to simply introduce proxy support to any app by including extensions to the core classes.

I wouldn't recommend this unless there are too many libs to patch / you don't control the code directly

```crystal

# Patches ::HTTP::Client

require "connect-proxy/ext/http-client"

# Patches ::HTTP::Websocket

require "connect-proxy/ext/websocket"

```

This method requires you to use the standard proxy ENV vars
