We need a place to store information about the available books.
Let's use a simple slice within our books handler.
}
-type books struct{}
+type books struct {
+ all []book
+}
+
+type book struct {
+ Title string `json:"title"`
+}
func (h *books) ServeHTTP(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
model := struct {
- Message string `json:"message"`
+ Books []book `json:"books"`
}{
- "No books available!",
+ h.all,
}
json.NewEncoder(w).Encode(model)
}
