Golang从文件中嵌入HTML [英] Golang embed html from file
问题描述
如果我有这样的HTML文件，该如何在Golang中进行操作:
How can I do in Golang if I have an HTML file like this:
<html>
<head lang="en">
</head>
<body>
<header>{{.Header}}</header>
<div class="panel panel-default">
</div>
</body>
</html>
我想将一部分代码嵌入到其他文件的标头标签中，如下所示:
and I want to embed a part of code into to header tags from an other file like this:
<div id="logo"></div><div id="motto"></div>
我的尝试:
header, _ := template.ParseFiles("header.html")
c := Content{Header: ""}
header.Execute(c.Header, nil)
index := template.Must(template.ParseFiles("index.html"))
index.Execute(w, c)
推荐答案
如果使用">code> template.ParseGlob() ，这些模板可以互相引用，也可以互相包含.
If you parse all your template files with template.ParseFiles() or with template.ParseGlob(), the templates can refer to each other, they can include each other.
将您的 index.html 更改为包含 header.html ，如下所示:
Change your index.html to include the header.html like this:
<html>
<head lang="en">
</head>
<body>
<header>{{template "header.html"}}</header>
<div class="panel panel-default">
</div>
</body>
</html>
然后是完整的程序(从当前目录解析文件，执行"index.html" 并将结果写入标准输出):
And then the complete program (which parses files from the current directory, executes "index.html" and writes the result to the standard output):
t, err := template.ParseFiles("index.html", "header.html")
if err != nil {
panic(err)
}
err = t.ExecuteTemplate(os.Stdout, "index.html", nil)
if err != nil {
panic(err)
}
使用 template.ParseGlob()可能看起来像这样:
With template.ParseGlob() it could look like this:
t, err := template.ParseGlob("*.html")
// ...and the rest is the same...
输出(打印在控制台上):
The output (printed on the console):
<html>
<head lang="en">
</head>
<body>
<header><div id="logo"></div><div id="motto"></div></header>
<div class="panel panel-default">
</div>
</body>
</html>
