MPS (middle-proxy-server) is an high-performance middle proxy library. support HTTP, HTTPS, Websocket, ForwardProxy, ReverseProxy, TunnelProxy, MitmProxy.
- Http Proxy
- Https Proxy
- Forward Proxy

A simple proxy service
package main
import (
"github.com/telanflow/mps"
"log"
"net/http"
)
func main() {
proxy := mps.NewHttpProxy()
log.Fatal(http.ListenAndServe(":8080", proxy))
}More examples
Middleware can intercept requests and responses. we have several middleware implementations built in, including BasicAuth
func main() {
proxy := mps.NewHttpProxy()
proxy.Use(mps.MiddlewareFunc(func(req *http.Request, ctx *mps.Context) (*http.Response, error) {
log.Printf("[INFO] middleware -- %s %s", req.Method, req.URL)
return ctx.Next(req)
}))
proxy.UseFunc(func(req *http.Request, ctx *mps.Context) (*http.Response, error) {
log.Printf("[INFO] middleware -- %s %s", req.Method, req.URL)
resp, err := ctx.Next(req)
if err != nil {
return nil, err
}
log.Printf("[INFO] resp -- %d", resp.StatusCode)
return resp, err
})
log.Fatal(http.ListenAndServe(":8080", proxy))
}Filters can filter requests and responses for unified processing. It is based on middleware implementation.
func main() {
proxy := mps.NewHttpProxy()
// request Filter Group
reqGroup := proxy.OnRequest(mps.FilterHostMatches(regexp.MustCompile("^.*$")))
reqGroup.DoFunc(func(req *http.Request, ctx *mps.Context) (*http.Request, *http.Response) {
log.Printf("[INFO] req -- %s %s", req.Method, req.URL)
return req, nil
})
// response Filter Group
respGroup := proxy.OnResponse()
respGroup.DoFunc(func(resp *http.Response, err error, ctx *mps.Context) (*http.Response, error) {
if err != nil {
log.Printf("[ERRO] resp -- %s %v", ctx.Request.Method, err)
return nil, err
}
log.Printf("[INFO] resp -- %d", resp.StatusCode)
return resp, err
})
log.Fatal(http.ListenAndServe(":8080", proxy))
