}
func testRange(w http.ResponseWriter, req *http.Request){
users:=[]model.User{

//解析模板文件
t:=template.Must(template.ParseFiles("range.html"))
//执行

}
func testWith(w http.ResponseWriter, req *http.Request){
//解析模板文件
t:=template.Must(template.ParseFiles("with.html"))
//执行
t.Execute(w, "狸猫")
}
func testTemplate(w http.ResponseWriter, req *http.Request){
//解析模板文件
t:=template.Must(template.ParseFiles("template1.html","template2.html"))
//执行
t.Execute(w, "我能在两个文件中显示吗？")
}
