# Adapters
|
|
|
|
Adapters is a collection of useful HTTP middleware or "Adapters". They follow the Adapter Pattern described by Mat Ryer in his blog post [Writing middleware in #golang and how Go makes it so much fun.](https://medium.com/@matryer/writing-middleware-in-golang-and-how-go-makes-it-so-much-fun-4375c1246e81)
|
|
|
|
Adapters can be chained in any way and will be executed in the order they are specified.
|
|
|
|
## Usage
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"log"
|
|
"net/http"
|
|
|
|
"github.com/mastertinner/adapters"
|
|
"github.com/mastertinner/adapters/logging"
|
|
)
|
|
|
|
// IndexHandler says what it loves
|
|
func IndexHandler() http.Handler {
|
|
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
|
fmt.Fprintf(w, "Hi there, I love %s!", r.URL.Path[1:])
|
|
})
|
|
}
|
|
|
|
func main() {
|
|
logger := log.New(os.Stdout, "", log.Ldate|log.Ltime)
|
|
http.Handle("/", adapters.Adapt(IndexHandler(), logging.Handler(logger)))
|
|
log.Fatal(http.ListenAndServe(":8080", nil))
|
|
}
|
|
```
|
|
|
|
## Adapters
|
|
|
|
This package contains the following adapters:
|
|
|
|
* Logging: Logs the request and the time it took to serve it
|
|
* OAuth2: Checks if a request is authenticated through [OAuth 2](https://oauth.net/2/) using [Redis](https://redis.io/) as a cache
