英文:
go error: undefined: "html/template".ParseFile
问题
在编译代码时，我遇到了以下错误：
“html/template undefined: "html/template".ParseFile”
错误出现在源代码的这一行：
t, _ := template.ParseFile("edit.html", nil)
以下是代码的翻译版本：
package main
import (
"net/http"
"io/ioutil"
"html/template"
)
type Page struct {
Title string
Body []byte
}
func (p *Page) save() error {
filename := p.Title + ".txt"
return ioutil.WriteFile(filename, p.Body, 0600)
}
func loadPage(title string) (*Page, error) {
filename := title + ".txt"
body, err := ioutil.ReadFile(filename)
if err != nil {
return nil, err
}
return &Page{Title: title, Body: body}, nil
}
const lenPath = len("/view/")
func editHandler(w http.ResponseWriter, r *http.Request) {
title := r.URL.Path[lenPath:]
p, err := loadPage(title)
if err != nil {
p = &Page{Title: title}
}
t, _ := template.ParseFile("edit.html", nil)
t.Execute(p, w)
}
func main() {
http.HandleFunc("/edit/", editHandler)
http.ListenAndServe(":8080", nil)
}
请帮我解决这个错误。

得分: 1
应该是template.ParseFiles("edit.html")。
复数形式而不是单数形式。
http://golang.org/pkg/html/template/#ParseFiles
英文:
It should be template.ParseFiles("edit.html")
plural not singular
