proxy

proxy library supported http(s) and socks5 protocol.

http

https://tools.ietf.org/html/rfc7230#section-5.7.2

supported user/pass authentication.

• ServerConf.Check: set true.
• ServerHandler.CheckUserPass: check input user/pass is valid.

supported https proxy with set ServerConf.Key and ServerConf.Crt field.

server example

var cfg proxy.ServerConf
// cfg.Key = "server.key"
// cfg.Crt = "server.crt"
svr := proxy.NewServer(cfg, ":1080")
assert(svr.ListenAndServe())
// assert(svr.ListenAndServeTLS())

client example

req, err := http.NewRequest("GET", "http://myip.ipip.net", nil)
assert(err)
httpCli := &http.Client{
    Transport: &http.Transport{
        Proxy: func(req *http.Request) (*url.URL, error) {
            return url.Parse("http://127.0.0.1:1080")
        },
        // TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    },
}
rep, err := httpCli.Do(req)
assert(err)
defer rep.Body.Close()
data, _ := ioutil.ReadAll(rep.Body)
fmt.Print(string(data))

socks5

https://tools.ietf.org/html/rfc1928

supported user/pass authentication.

• ServerHandler.Handshake: check input supported socks5.MethodUserPass and return that.
• ServerHandler.CheckUserPass: check input user/pass is valid.
• Client.DialUserPass: dial connection by user/pass.

server example

var cfg socks5.ServerConf
svr := socks5.NewServer(cfg)
svr.ListenAndServe(":1080")

client example

var cfg socks5.ClientConf
cli, err := socks5.NewClient(cfg)
if err != nil {
    panic(err)
}
req, err := http.NewRequest("GET", "http://myip.ipip.net", nil)
if err != nil {
    panic(err)
}
httpCli := &http.Client{
    Transport: &http.Transport{
        Dial: func(network, addr string) (net.Conn, error) {
            return cli.Dial(addr)
        },
    },
}
rep, err := httpCli.Do(req)
if err != nil {
    panic(err)
}
defer rep.Body.Close()
data, _ := ioutil.ReadAll(rep.Body)
fmt.Print(string(data))
