Passing value to static page Golang
问题
我是你的中文翻译助手，以下是翻译好的内容：
我对Golang还不熟悉。如何将值传递给静态页面？
假设我有以下代码：
// webtes项目的main.go文件
package main
import (
"log"
"net/http"
)
func main() {
http.HandleFunc("/sayName", func(writer http.ResponseWriter, r *http.Request) {
name := "Jon Snow"
http.ServeFile(writer, r, "static/sayName.html")/*我如何将'name'传递给这个静态页面并打印出来？*/
})
log.Fatal(http.ListenAndServe(":8081", nil))
}
static/sayName.html
<!doctype html>
<html>
<head></head>
<body>{/*在这里打印name*/}</body>
</html>
我想将变量"name"传递给静态页面"sayName.html"并在那里打印出来。我该如何实现？谢谢。

常见的方法是将sayName.html作为html/template处理，并在每个请求上执行它。
然后，你的处理程序可以是这样的：
func templateHandler(w http.ResponseWriter, r *http.Request){
tplTxt,err := ioutil.ReadFile(...)
// 错误处理
tpl := template.Must(template.New("").Parse(string(tplTxt)))
templateData := map[string]interface{}{"Name":"Jon Snow"}
tpl.Execute(w, templateData)
}
你的HTML模板可以使用{{.Name}}来插入名称。
你应该缓存解析后的模板并更好地处理错误，但这是一般的思路。
英文:
A common approach it to make sayName.html an html/template, and execute it on each request.
Then your handler is something like:
func templateHandler(w http.ResponseWriter, r *http.Request){
tplTxt,err := ioutil.ReadFile(...)
//error handling
tpl := template.Must(template.New("").Parse(string(tplTxt)))
templateData := map[string]interface{}{"Name":"Jon Snow"}
tpl.Execute(w, templateData)
}
And your html template can use {{.Name}} to insert the name.
You should cache the parsed templates and handle errors better, but thats the general idea.
