My scenario
Compiled angular projects are saved like
.
├── branch1
│ ├── commitC
│ │ ├── app1
│ │ │ ├── index.html
│ │ │ └── stylesheet.css
│ └── commitD
│ ├── app1
│ │ ├── index.html
│ │ └── stylesheet.css
│ └── app2
│ ├── index.html
│ └── stylesheet.css
├── branch2
│ ├── commitE
│ ├── app1
│ │ ├── index.html
│ │ └── stylesheet.css
│ └── app2
│ ├── index.html
│ └── stylesheet.css
└── master
├── commitA
│ ├── app1
│ │ ├── index.html
│ │ └── stylesheet.css
└── commitB
├── app1
├── index.html
└── stylesheet.css
Database
TABLE data(id , branch, commit)
Entries: e.g.
| id | branch | commit |
|---|---|---|
| abc | branch1 | commitC |
| def | branch1 | commitD |
| ghi | master | commitA |
Now I want to access
:8080/apps/{id}
e.g.: localhost:8080/apps/abc
the path should will be generated after requesting the DB entry
and a fileserver serves the directory ./files/branch1/commitC/
now i would expect to see the folders app1 and app2
What I have
func main() {
mux = mux.NewRouter()
mux.HandleFunc("/apps/{id}/{app}", s.serveApp).Methods("GET")
}
func (s *Server) serveApp(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
app := params["app"]
id := params["id"]
entry, err := getFromDB(id)
if err != nil {
w.Header().Set("Content-Type", "text/html")
respondWithError(w, http.StatusInternalServerError, err.Error())
return
}
file := filepath.Join(DefaultFolder, entry.Branch, entry.Commit, app, "index.html")
fmt.Printf("redirecting to %s", file)
http.ServeFile(w, r, file)
}
how can I serve the whole directory like that, so all css and js files can be accessed correctly?
I think I need something like this
http.Handle("/tmpfiles/", http.StripPrefix("/tmpfiles/", http.FileServer(http.Dir("/tmp"))))
but how can a access mux.Vars(request) to build up the directory path?
############ Regarding CSS serving problem
import (
"log"
"net/http"
"github.com/gorilla/mux"
)
func main() {
mux := mux.NewRouter()
fs := http.FileServer(http.Dir("static"))
mux.Handle("/", fs)
log.Println("Listening...")
http.ListenAndServe(":3000", mux)
}
CSS files are served as 'text/plain'
Files:
- main.go
- static/
- index.html
- main.css
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>A static page</title>
<link rel="stylesheet" href="main.css">
</head>
<body>
<h1>Hello from a static page</h1>
</body>
</html>
main.css
body {color: #c0392b}
http.FileServerreturns a handler. This handler can be called manually instead of registered to a fix path.You pass the original
w http.ResponseWriter, r *http.Requestparameters to it, so the http.FileServer is able to access the request and write the response.You will probably need to wrap the
http.FileServerinto ahttp.StripPrefixhandler so the path in the original request gets stripped down to a path relativ to thepathvariable.
