Google App Engine with Golang: How do you parse URL path segments as variables?

In Google App Engine with Go, I would like to take a URL like this:

http://www.example.com/api/account/123456/product/573832

and treat it like this:

http://www.example.com/api/account/{acctId}/product/{prodId}

Then access acctId and prodId in my handler function.

How do I do this?

There you are:

func httpHandle(httpResponse http.ResponseWriter, httpRequest *http.Request) {
	urlPart := strings.Split(httpRequest.URL.Path, "/")
	// urlPart[3] is the acctId, urlPart[5] is the prodId
}

httprouter seems to be fast and simplistic. If you need a more advanced sophisticated routing framework then look elsewhere?

go get github.com/julienschmidt/httprouter

then:

package goseo

import (
    "fmt"
    "net/http"
    "github.com/julienschmidt/httprouter"
)

func init() {
    router := httprouter.New()
    router.GET("/", index)
    http.Handle("/", router)
}

func index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
    fmt.Fprint(w, "Hello, world!")
}

example matches:

Pattern: /user/:user

 /user/gordon              match
 /user/you                 match
 /user/gordon/profile      no match
 /user/                    no match

Further, I have an app.yaml:

application: student-course-review
module: goseo
version: goseo1
runtime: go
api_version: go1

handlers:
- url: /static/(.+)
  static_files: static/
  upload: static/(.*)

- url: /.*
  script: _go_app

You might want to consider using a library, like "httprouter" for this. This guide might help you choose one.
