如何渲染多个模板
创建了一个基本模板。随着呈现的 first.html 又一个模板。
eg. :
var tmpl = template.Must(template.ParseFiles(
"templates/base.html",
"templates/first.html",
))
但我也想添加更多的 .html 文件来渲染。有参考吗？

如果在模板文件夹中定义所有模板，则可以使用以下命令轻松解析整个目录：template.Must(template.ParseGlob("YOURDIRECTORY/*"))例如：头文件{{define "header"}} <head> <title>Index</title> </head>{{end}}索引.html{{define "indexPage"}} <html> {{template "header"}} <body> <h1>Index</h1> </body> </html>{{end}}main.gopackage mainimport( "html/template")// compile all templates and cache themvar templates = template.Must(template.ParseGlob("YOURTEMPLATEDIR/*"))func main(){ ...}func IndexHandler(w http.ResponseWriter, r *http.Request) { // you access the cached templates with the defined name, not the filename err := templates.ExecuteTemplate(w, "indexPage", nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return }}你执行你的 indexPage-Template templates.ExecuteTemplate(w, "indexPage", nil) -

如果你想用特定文件解析多个目录，这里有一个代码片段：//parse a pattern in a specific directory allTemplates := template.Must(template.ParseGlob("Directory/*"))//add another directory for parsing allTemplates = template.Must(allTemplates.ParseGlob("Another_Directory/*.tmpl"))//add specific file name allTemplates = template.Must(allTemplates.ParseFiles("path/to/file.tmpl"))func main() { ...}func FileHandler(w http.ResponseWriter, r *http.Request) { // access cached template by file name (in case you didn't define its name) err := allTemplates.ExecuteTemplate(w, "file.tmpl", nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return }}func NameHandler(w http.ResponseWriter, r *http.Request) { // access cached template by handler name err := allTemplates.ExecuteTemplate(w, "handlerName", nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return }}快捷方式：allTemplates := template.Must( template.Must( template.Must( template.ParseGlob("directory/*.tmpl")). ParseGlob("another_directory/*.tmpl")). ParseFiles("path/to/file.tmpl")), )file.tmpl 可以如下所示：<html>This is a template file </html>name.tmpl 应该看起来像这样{{define "handlerName" }}<p>this is a handler</p>{{end}}
