I'm fairly certain that I've overlooked something obvious, but I'm not sure what. I'm building a simple web application that serves up templated pages of books. The template works fine, and the path for the image seems to be populating correctly, but I keep getting a 404 error for the image itself.
Here is the template:
<h1>{{.Title}}</h1>
<h2>{{.Author.Name}}</h2>
<image src="../images/{{.ImageURI}}" />
and here is the application itself:
package main
import (
"html/template"
"log"
"net/http"
"time"
"github.com/gorilla/mux"
"github.com/user/marketplace/typelibrary"
)
var books []typelibrary.Book
func ItemHandler(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
var selected typelibrary.Book
//Retrieve item data
for _, item := range books {
if item.ID == params["id"] {
selected = item
break
}
}
t, _ := template.ParseFiles("./templates/book.html")
t.Execute(w, selected)
}
func main() {
router := mux.NewRouter()
books = append(books, typelibrary.Book{ID: "1", Title: "The Fellowship of the Ring", ImageURI: "LotR-FotR.jpg", Author: &typelibrary.Author{Name: "JRR Tolkien"}})
books = append(books, typelibrary.Book{ID: "2", Title: "The Two Towers", ImageURI: "LotR-tTT.jpg", Author: &typelibrary.Author{Name: "JRR Tolkien"}})
books = append(books, typelibrary.Book{ID: "3", Title: "The Return of the King", ImageURI: "LotR-RotK.jpg", Author: &typelibrary.Author{Name: "JRR Tolkien"}})
books = append(books, typelibrary.Book{ID: "4", Title: "Monster Hunter International", ImageURI: "MHI1.jpg", Author: &typelibrary.Author{Name: "Larry Correia"}})
router.Handle("/", http.FileServer(http.Dir(".")))
router.Handle("/images/", http.FileServer(http.Dir("../images/")))
router.HandleFunc("/item/{id}", ItemHandler).Methods("GET")
srv := &http.Server{
Handler: router,
Addr: ":8080",
WriteTimeout: 10 * time.Second,
ReadTimeout: 10 * time.Second,
}
log.Fatal(srv.ListenAndServe())
}
The images are stored in the images
subdirectory, directly below the directory where the executable is. When I attempt to view the broken image in the page, the path shows up as localhost:8080/images/[imagename]
but gives a 404 error. What configuration or routing options am I missing here?
