如何在Golang中将模板输出写入文件？

使用数组作为第二个参数，而不是模板本身。

package mainimport (        "html/template"        "log"        "os")func main() {        t := template.Must(template.New("").Parse(`{{- range .}}{{.}}:        echo "from {{.}}"{{end}}`))        t.Execute(os.Stdout, []string{"app1", "app2", "app3"})        f, err := os.Create("./myfile")        if err != nil {     log.Println("create file: ", err)     return        }        err = t.Execute(f, []string{"app1", "app2", "app3"})        if err != nil {     log.Print("execute: ", err)     return        }        f.Close()}

输出：

app1:    echo "from app1"app2:    echo "from app2"app3:    echo "from app3"

而且的内容

myfile

app1:    echo "from app1"app2:    echo "from app2"app3:    echo "from app3"
