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](http://httpd.apache.org/docs/2.2/logs.html#common).
|
||
|
|
* `CombinedLoggingHandler` for logging HTTP requests in the Apache [Combined Log
|
||
|
|
Format](http://httpd.apache.org/docs/2.2/logs.html#combined) 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.RemoteAddr` and `r.URL.Scheme` based on the
|
||
|
|
`X-Forwarded-For`, `X-Real-IP`, `X-Forwarded-Proto` and RFC7239 `Forwarded`
|
||
|
|
headers 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).
|
||
|
|
|
||
|
|
Other handlers are documented [on the Gorilla
|
||
|
|
website](http://www.gorillatoolkit.org/pkg/handlers).

## Example
|
||
|
|
|
||
|
|
A simple example using `handlers.LoggingHandler` and `handlers.CompressHandler`:
|
||
|
|
|
||
|
|
```go
|
||
|
|
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))
|
||
|
|
}
|
||
|
|
```
