我写了一个包装函数来渲染这样的模板
func RenderTemplate(w http.ResponseWriter, data interface{}, tmpl... string) {
cwd, _ := os.Getwd()
for _ , file := range tmpl{
file = filepath.Join(cwd,"./view/"+file+".html")
}
t, err := template.ParseFiles(tmpl...)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
err = t.Execute(w, data)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
}
我在 main 中设置静态文件夹和路由处理程序
http.Handle("/public/",http.StripPrefix("/public/",http.FileServer(http.Dir("public"))))
http.HandleFunc("/",route.IndexHandler)
这是我的路由处理器
func IndexHandler(w http.ResponseWriter, r *http.Request) {
files:=[]string{"base","index"}
util.RenderTemplate(w, nil, files...)
}
我打算使用模板嵌套来帮助index.html扩展base.html
这是base.html
{{define "base"}}
<!DOCTYPE html>
<html>
<head>
<meta charget="utf-8">
<title>{{template "title".}}</title>

</head>
<body>
{{template "index".}}
</body>
</html>
{{end}}
这是index.html
<!DOCTYPE html>
<html>
{{define "title"}}Homepage{{end}}
<body>
{{define "index"}}
<div class="wrapper">
<div class="page-content">
<div class="container">
<div class="left">

<div class="right">

</div>
</div>
</div>
</div>
{{end}}
</body>
</html>
但是当我运行服务器，并在浏览器上请求路径时，它显示错误
open base: 没有那个文件或目录
我的渲染函数有问题吗？
最佳答案
t, err := template.ParseFiles(tmpl...)
我猜 `tmpl' 似乎不是一个文件路径 :(
我猜你想喜欢这个。
files := make([]string, len(tmpl))
for i, file := range tmpl{
files[i] = appendfilepath.Join(cwd,"./view/"+file+".html")
}
t, err := template.ParseFiles(files...)
关于html - go - 打开文件没有那个文件或目录，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35905338/
