gorilla/handlers
Package handlers is a collection of handlers (aka "HTTP middleware") for use
with Go's net/http package (or any framework supporting http.Handler), including:
- LoggingHandler for logging HTTP requests in the Apache Common Log Format.
- CombinedLoggingHandler for logging HTTP requests in the Apache Combined Log Format commonly used by both Apache and nginx.
- CompressHandler for gzipping responses.
- ContentTypeHandler for validating requests against a list of accepted content types.
- MethodHandler for matching HTTP methods against handlers in a
map[string]http.Handler - ProxyHeaders for populating
r.RemoteAddrandr.URL.Schemebased on theX-Forwarded-For,X-Real-IP,X-Forwarded-Protoand RFC7239Forwardedheaders when running a Go server behind a HTTP reverse proxy. - CanonicalHost for re-directing to the preferred host when handling multiple domains (i.e. multiple CNAME aliases).
- RecoveryHandler for recovering from unexpected panics.
Other handlers are documented on the Gorilla website.
Example
A simple example using handlers.LoggingHandler and handlers.CompressHandler:
import (
"net/http"
"github.com/gorilla/handlers"
)
func main() {
r := http.NewServeMux()
// Only log requests to our admin dashboard to stdout
r.Handle("/admin", handlers.LoggingHandler(os.Stdout, http.HandlerFunc(ShowAdminDashboard)))
r.HandleFunc("/", ShowIndex)
// Wrap our server with our gzip handler to gzip compress all responses.
http.ListenAndServe(":8000", handlers.CompressHandler(r))
