如果在模板文件夾中定義所有模板，則可以使用以下命令輕松解析整個目錄：
template.Must(template.ParseGlob("YOURDIRECTORY/*"))
例如：
頭文件
{{define "header"}}
<head>
<title>Index</title>
</head>
{{end}}
索引.html
{{define "indexPage"}}
<html>
{{template "header"}}
<body>
<h1>Index</h1>
</body>
</html>
{{end}}
main.go
package main
import(
"html/template"
)
// compile all templates and cache them
var templates = template.Must(template.ParseGlob("YOURTEMPLATEDIR/*"))
func main(){
...
}
func IndexHandler(w http.ResponseWriter, r *http.Request) {
// you access the cached templates with the defined name, not the filename
err := templates.ExecuteTemplate(w, "indexPage", nil)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
}
你執行你的 indexPage-Template templates.ExecuteTemplate(w, "indexPage", nil)

如果你想用特定文件解析多個目錄，這里有一個代碼片段：
//parse a pattern in a specific directory
allTemplates := template.Must(template.ParseGlob("Directory/*"))
//add another directory for parsing
allTemplates = template.Must(allTemplates.ParseGlob("Another_Directory/*.tmpl"))
//add specific file name
allTemplates = template.Must(allTemplates.ParseFiles("path/to/file.tmpl"))
func main() {
...
}
func FileHandler(w http.ResponseWriter, r *http.Request) {
// access cached template by file name (in case you didn't define its name)
err := allTemplates.ExecuteTemplate(w, "file.tmpl", nil)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
}
func NameHandler(w http.ResponseWriter, r *http.Request) {
// access cached template by handler name
err := allTemplates.ExecuteTemplate(w, "handlerName", nil)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
}
快捷方式：
allTemplates := template.Must(
template.Must(
template.Must(
template.ParseGlob("directory/*.tmpl")).
ParseGlob("another_directory/*.tmpl")).
ParseFiles("path/to/file.tmpl")),
)
file.tmpl 可以如下所示：
<html>
This is a template file
</html>
name.tmpl 應該看起來像這樣
{{define "handlerName" }}
<p>this is a handler</p>
{{end}}
