我有一个具有 JSON 字段的结构,如下所示:
详细信息 := &Detail{ 名称字符串详细信息 json.RawMessage }
模板看起来像这样:
细节=At {{Name}} {{CreatedAt}} {{UpdatedAt}}
我的问题是我们可以为单个模板使用一个或多个结构,还是仅限于一个结构。
你可以传递任意数量的东西。您没有提供太多可供使用的示例,因此我将假设一些事情,但您将如何解决它:
// Shorthand - useful!
type M map[string]interface
func SomeHandler(w http.ResponseWriter, r *http.Request) {
detail := Detail{}
// From a DB, or API response, etc.
populateDetail(&detail)
user := User{}
populateUser(&user)
// Get a session, set headers, etc.
// Assuming tmpl is already a defined *template.Template
tmpl.RenderTemplate(w, "index.tmpl", M{
// We can pass as many things as we like
"detail": detail,
"profile": user,
"status": "", // Just an example
}
}

...以及我们的模板:
<!DOCTYPE html>
<html>
<body>
// Using "with"
{{ with .detail }}
{{ .Name }}
{{ .CreatedAt }}
{{ .UpdatedAt }}
{{ end }}
// ... or the fully-qualified way
// User has fields "Name", "Email", "Address". We'll use just two.
Hi there, {{ .profile.Name }}!
Logged in as {{ .profile.Email }}
</body>
</html>

希望能澄清。
