模板渲染存储文件
(index.html同模板渲染终端index.html保持不变)
~~~
package main
import (
"os"
"fmt"
"html/template"
// "io"
"net/http"
)
var myTemplate *template.Template
type Person struct {
Name string
age string
}
func userInfo(w http.ResponseWriter,r *http.Request) {
p := Person{Name:"Murphy",age:"28"}
myTemplate.Execute(os.Stdout,p)
file,err := os.OpenFile("demo.dat", os.O_CREATE|os.O_WRONLY, 0755)
if err != nil {
fmt.Println("open failed err:", err)
return
}
myTemplate.Execute(file,p)
}
func initTemplate(fileName string) (err error){
myTemplate,err = template.ParseFiles(fileName)
if err != nil{
fmt.Println("parse file err:",err)
return
}
return
}
/*
func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {
DefaultServeMux.HandleFunc(pattern, handler)
}
*/
func main() {
initTemplate("./index.html")
http.HandleFunc("/user/info", userInfo)
err := http.ListenAndServe("0.0.0.0:8880", nil)
if err != nil {
fmt.Println("http listen failed")
}
}

命令行：
$ go run main.go
然后在浏览器中输入 :
http://localhost:8880/user/info
命令行显示：
~~~
';
hello,Murphy {Murphy 28}
~~~ 命令行： control+c ^Csignal: interrupt $ ls demo.dat index.html main.go $ cat demo.dat ~~~hello,Murphy {Murphy 28}
