func (*HttpReverseProxy) Register

func (rp *HttpReverseProxy) Register(routeCfg VhostRouteConfig) error

Register register the route config to reverse proxy reverse proxy will use CreateConnFn from routeCfg to create a connection to the remote service

func (*HttpReverseProxy) ServeHTTP

func (rp *HttpReverseProxy) ServeHTTP(rw http.ResponseWriter, req *http.Request)

func (*HttpReverseProxy) UnRegister

func (rp *HttpReverseProxy) UnRegister(domain string, location string)

UnRegister unregister route config by domain and location

	ResponseHeaderTimeoutS int64
}

type HttpsMuxer

type HttpsMuxer struct {
	*VhostMuxer
}

func NewHttpsMuxer

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

func (*Listener) Accept

func (l *Listener) Accept() (net.Conn, error)

func (*Listener) Addr

func (l *Listener) Addr() net.Addr

func (*Listener) Close

func (l *Listener) Close() error

func (*Listener) Name

func (l *Listener) Name() string

type ReverseProxy

type ReverseProxy 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 must not access the provided Request
	// after returning.
	Director func(*http.Request)

	// The transport used to perform proxy requests.
	// If nil, http.DefaultTransport is used.
	Transport http.RoundTripper

	// FlushInterval specifies the flush interval
	// to flush to the client while copying the
	// response body.
	// If zero, no periodic flushing is done.
	// A negative value means to flush immediately
	// after each write to the client.
	// The FlushInterval is ignored when ReverseProxy
	// recognizes a response as a streaming response;
	// for such responses, writes are flushed to the client
	// immediately.
	FlushInterval time.Duration

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

	// BufferPool optionally specifies a buffer pool to
	// get byte slices for use by io.CopyBuffer when
	// copying HTTP response bodies.
	BufferPool BufferPool

	// ModifyResponse is an optional function that modifies the
	// Response from the backend. It is called if the backend
	// returns a response at all, with any HTTP status code.
	// If the backend is unreachable, the optional ErrorHandler is
	// called without any call to ModifyResponse.
	//
	// If ModifyResponse returns an error, ErrorHandler is called
	// with its error value. If ErrorHandler is nil, its default
	// implementation is used.
	ModifyResponse func(*http.Response) error

	// ErrorHandler is an optional function that handles errors
	// reaching the backend or errors from ModifyResponse.
	//
	// If nil, the default is to log the provided error and return
	// a 502 Status Bad Gateway response.
	ErrorHandler func(http.ResponseWriter, *http.Request, error)
}

ReverseProxy is an HTTP Handler that takes an incoming request and sends it to another server, proxying the response back to the client.

func NewSingleHostReverseProxy

func NewSingleHostReverseProxy(target *url.URL) *ReverseProxy

NewSingleHostReverseProxy returns a new ReverseProxy that routes URLs to the scheme, host, and base path provided in target. If the target's path is "/base" and the incoming request was for "/dir", the target request will be for /base/dir. NewSingleHostReverseProxy does not rewrite the Host header. To rewrite Host headers, use ReverseProxy directly with a custom Director policy.

func (*ReverseProxy) ServeHTTP

func (p *ReverseProxy) ServeHTTP(rw http.ResponseWriter, req *http.Request)

type VhostMuxer

type VhostMuxer struct {
	// contains filtered or unexported fields

func (v *VhostMuxer) Listen(ctx context.Context, cfg *VhostRouteConfig) (l *Listener, err error)

listen for a new domain name, if rewriteHost is not empty and rewriteFunc is not nil then rewrite the host header to rewriteHost
