Functions

func IsWebSocketRequest

func IsWebSocketRequest(r *http.Request) bool

IsWebSocketRequest returns a boolean indicating whether the request has the headers of a WebSocket handshake request.

Types

type HTTPReverseProxy

type HTTPReverseProxy struct {
	// contains filtered or unexported fields
}

HTTPReverseProxy it work with a regular HTTP request

func NewHTTPReverseProxy

func NewHTTPReverseProxy(target *url.URL, rpc *rpc.Client) *HTTPReverseProxy

NewHTTPReverseProxy create new http-proxy-handler

func (*HTTPReverseProxy) ServeHTTP

func (handler *HTTPReverseProxy) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Proxy

type Proxy struct {
	// contains filtered or unexported fields
}

Proxy accept http and ws requests

func New

func New(addr *url.URL, rpc *rpc.Client) *Proxy

New create new router

func (*Proxy) ServeHTTP

func (p *Proxy) ServeHTTP(w http.ResponseWriter, r *http.Request)

type WebsocketReverseProxy

type WebsocketReverseProxy struct {
	// Director must be a function which modifies
	// the request into a new request to be sent
	// using Transport. Its response is then copied
	// back to the original client unmodified.
	Director func(*http.Request)

	// Dial specifies the dial function for dialing the proxied
	// server over tcp.
	// If Dial is nil, net.Dial is used.
	Dial func(network, addr string) (net.Conn, error)

	// TLSClientConfig specifies the TLS configuration to use for 'wss'.
	// If nil, the default configuration is used.
	TLSClientConfig *tls.Config

	// ErrorLog specifies an optional logger for errors
	// that occur when attempting to proxy the request.
	// If nil, logging goes to os.Stderr via the log package's
	// standard logger.
	ErrorLog *log.Logger
}

WebsocketReverseProxy it will not work with a regular HTTP request, so it is the caller's responsiblity to ensure the incoming request is a WebSocket request.

func NewWebsocketReverseProxy

func NewWebsocketReverseProxy(target *url.URL) *WebsocketReverseProxy

NewWebsocketReverseProxy returns a new websocket ReverseProxy. The path rewrites follow the same rules as the httputil.ReverseProxy. If the target url has the path '/foo' and the incoming request '/bar', the request path will be updated to '/foo/bar' before forwarding. Scheme should specify if 'ws' or 'wss' should be used.

func (*WebsocketReverseProxy) ServeHTTP

func (p *WebsocketReverseProxy) ServeHTTP(w http.ResponseWriter, r *http.Request)

Function to implement the http.Handler interface.
