您可以尝试使用template.Lookup,整个过程如下所示:
var (
templates *template.Template
)
func loadTemplate() {
funcMap := template.FuncMap{
"safe":func(s string) template.HTML {
return template.HTML(s)
},
}
var err error
templates, err = utils.BuildTemplate("/theme/path/", funcMap)
if err != nil {
log.Printf("Can't read template file %v,", err)
}
}
func homeHandler(w http.ResponseWriter, r *http.Request) {
//lookup the theme your want to use
templ = templates.Lookup("theme.html")
err := templ.Execute(w, data)
if err != nil {
log.Println(err)
}
}
func main() {
loadTemplate()
}
BuildTemplate看起来像:
func BuildTemplate(dir string, funcMap template.FuncMap) (*template.Template, error) {
fs, err := ioutil.ReadDir(dir)
if err != nil {
fmt.Printf("Can't read template folder: %s\n", dir)
return nil, err
}
files := make([]string, len(fs))
for i, f := range (fs) {
files[i] = path.Join(dir, f.Name())
}
return template.Must(template.New("Template").Funcs(funcMap).ParseFiles(files...)), nil
}
