### How to use?
|
||
|
|
|
||
|
|
pat is pretty simple. The documentation lives [here](http://www.gorillatoolkit.org/pkg/pat).
|
||
|
|
|
||
|
|
### Install
|
||
|
|
With a properly configured Go toolchain:
|
||
|
|
```sh
|
||
|
|
go get github.com/gorilla/pat
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
Here's an example of a RESTful api:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"log"
|
||
|
|
"net/http"
|
||
|
|
|
||
|
|
"github.com/gorilla/pat"
|
||
|
|
)
|
||
|
|
|
||
|
|
func homeHandler(wr http.ResponseWriter, req *http.Request) {
|
||
|
|
wr.WriteHeader(http.StatusOK)
|
||
|
|
wr.Write([]byte("Yay! We're home, Jim!"))
|
||
|
|
}
|
||
|
|
|
||
|
|
func getAllTheThings(wr http.ResponseWriter, req *http.Request) {
|
||
|
|
wr.WriteHeader(http.StatusOK)
|
||
|
|
wr.Write([]byte("Look, Jim! Get all the things!"))
|
||
|
|
}
|
||
|
|
|
||
|
|
func putOneThing(wr http.ResponseWriter, req *http.Request) {
|
||
|
|
wr.WriteHeader(http.StatusOK)
|
||
|
|
wr.Write([]byte("Look, Jim! Put one thing!"))
|
||
|
|
}
|
||
|
|
|
||
|
|
func deleteOneThing(wr http.ResponseWriter, req *http.Request) {
|
||
|
|
wr.WriteHeader(http.StatusOK)
|
||
|
|
wr.Write([]byte("Look, Jim! Delete one thing!"))
|
||
|
|
}
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
router := pat.New()
|
||
|
|
|
||
|
|
router.Get("/things", getAllTheThings)
|
||
|
|
|
||
|
|
router.Put("/things/{id}", putOneThing)
|
||
|
|
router.Delete("/things/{id}", deleteOneThing)
|
||
|
|
|
||
|
|
router.Get("/", homeHandler)
|
||
|
|
|
||
|
|
http.Handle("/", router)
|
||
|
|
|
||
|
|
log.Print("Listening on 127.0.0.1:8000...")
|
||
|
|
log.Fatal(http.ListenAndServe(":8000", nil))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
Notice how the routes descend? That's because Pat will take the first route
|
||
|
|
that matches. For your own testing, take the line ```router.Get("/",
|
||
|
|
homeHandler)``` and put it above the other routes and run the example. When you
|
||
|
|
try to curl any of the routes, you'll only get what the homeHandler returns.
|
||
|
|
Design your routes carefully.
