template包(html/template)实现了数据驱动的模板,用于生成可对抗代码注入的安全HTML输出。本包提供了和text/template包相同的接口,无论何时当输出是HTML的时候都应使用本包。

main.go

package mainimport (	"html/template"	"io/ioutil"	"os"	"time"	"fmt")func main() {	t := template.New("第一个模板").Delims("[[", "]]") //创建一个模板,设置模板边界	t, _ = t.Parse("hello,[[.UserName]]\n")       //解析模板文件	data := map[string]interface{}{"UserName": template.HTML("<script>alert('you have been pwned')</script>")}	t.Execute(os.Stdout, data) //执行模板的merger操作,并输出到控制台	t2 := template.New("新的模板")                         //创建模板	t2.Funcs(map[string]interface{}{"tihuan": tihuan}) //向模板中注入函数	bytes, _ := ioutil.ReadFile("test2.html")          //读文件	template.Must(t2.Parse(string(bytes)))             //将字符串读作模板	t2.Execute(os.Stdout, map[string]interface{}{"UserName": "你好世界"})	fmt.Println("\n", t2.Name(), "\n")	t3, _ := template.ParseFiles("test1.html") //将一个文件读作模板	t3.Execute(os.Stdout, data)	fmt.Println(t3.Name(), "\n") //模板名称	t4, _ := template.ParseGlob("test1.html") //将一个文件读作模板	t4.Execute(os.Stdout, data)	fmt.Println(t4.Name())}//注入模板的函数func tihuan(str string) string {	return str + "-------" + time.Now().Format("2006-01-02")}



test1.html

<!DOCTYPE html><html><head>	<title>template</title></head><body>hello {{.UserName}}<br></body></html>



test2.html

<!DOCTYPE html><html><head>	<title>template</title></head><body>hello {{.UserName}}<br>{{tihuan .UserName}}</body></html>
