使用 Go 模板在 GAE 中显示结构体中的数据（使用切片）

package main

import (
    "html/template"
    "net/http"
)

type Data struct {
    Items []string
}

func handler(w http.ResponseWriter, r *http.Request) {
    data := Data{
        Items: []string{"Item 1", "Item 2", "Item 3"},
    }

    tmpl, err := template.New("webpage").Parse(`
        <h1>Items:</h1>
        <ul>
        {{range .Items}}
            <li>{{.}}</li>
        {{end}}
        </ul>
    `)

    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }

    err = tmpl.Execute(w, data)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

tmpl, err := template.New("webpage").Parse(`
    <h1>Items:</h1>
    <ul>
    {{range .Items}}
        <li>{{.}}</li>
    {{end}}
    </ul>
`)

err = tmpl.Execute(w, data)
if err != nil {
    http.Error(w, err.Error(), http.StatusInternalServerError)
    return
}
