Specify names for parsed templates
问题
我正在尝试使用文件夹中的walk动态解析文件，并且我希望能够设置文件的路径"path/file.html"。但是我的问题是，如果我在文件夹"path/folder/files.html"中有一个文件，我无法这样做，因为当我执行ExecuteTemplate时，文件名将是相同的"files.html"。是否可以在ParseFiles时为每个模板命名？
如果一次尝试处理所有文件无法工作，我可以一个一个地处理文件。
// 解析文件并发送到responsewriter
func View(w http.ResponseWriter, path string) {
temp, err := template.ParseFiles("application/views/" + path + ".html")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
} else {
temp.ExecuteTemplate(w, path, nil)
}
}

I am trying to dynamically parse files using walk in a folder and I want to be able to set the path of the file "path/file.html". But my issue is if I have a file in a folder "path/folder/files.html" I can't do it because when I ExecuteTemplate the file name will be the same "files.html". Is it possible to name each template as I ParseFiles?
Im ok with doing a file one at a time if trying to do them all at once wont work.

// Parse file and send to responsewriter
func View(w http.ResponseWriter, path string) {
temp, err := template.ParseFiles("application/views/"+path+".html")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
} else {
temp.ExecuteTemplate(w, path, nil)
}
}

使用filepath.Walk和一个consumer方法遍历文件系统，该方法将使用完整的文件路径作为模板名称创建模板：
package main
import (
"fmt"
"html/template"
"os"
"path/filepath"
)
func consumer(p string, i os.FileInfo, e error) error {
t := template.New(p)
fmt.Println(t.Name())
return nil
}
func main() {
filepath.Walk("/path/to/template/root", filepath.WalkFunc(consumer))
}
英文:
Walk the filesystem using filepath.Walk and a consumer method that will create templates with the full file paths as names:
package main
import (
"fmt"
"html/template"
"os"
"path/filepath"
)
func consumer(p string, i os.FileInfo, e error) error {
t := template.New(p)
fmt.Println(t.Name())
return nil
}
func main() {
filepath.Walk("/path/to/template/root", filepath.WalkFunc(consumer))
}

你可以尝试使用template.Lookup，整个过程如下：
var (
templates *template.Template
)
func loadTemplate() {
funcMap := template.FuncMap{
"safe": func(s string) template.HTML {
return template.HTML(s)
},
}
var err error
templates, err = utils.BuildTemplate("/theme/path/", funcMap)
if err != nil {
log.Printf("无法读取模板文件 %v,", err)
}
}
func homeHandler(w http.ResponseWriter, r *http.Request) {
//查找你想要使用的主题
templ = templates.Lookup("theme.html")
err := templ.Execute(w, data)
if err != nil {
log.Println(err)
}
}
func main() {
loadTemplate()
}
BuildTemplate的样子如下：
func BuildTemplate(dir string, funcMap template.FuncMap) (*template.Template, error) {
fs, err := ioutil.ReadDir(dir)
if err != nil {
fmt.Printf("无法读取模板文件夹：%s\n", dir)
return nil, err
}
files := make([]string, len(fs))
for i, f := range (fs) {
files[i] = path.Join(dir, f.Name())
}
return template.Must(template.New("Template").Funcs(funcMap).ParseFiles(files...)), nil
}
英文:
You can try template.Lookup, the whole process looks like:
var (
templates *template.Template
)
func loadTemplate() {
funcMap := template.FuncMap{
"safe":func(s string) template.HTML {
return template.HTML(s)
},
}
var err error
templates, err = utils.BuildTemplate("/theme/path/", funcMap)
if err != nil {
log.Printf("Can't read template file %v,", err)
}
}
func homeHandler(w http.ResponseWriter, r *http.Request) {
//lookup the theme your want to use
templ = templates.Lookup("theme.html")
err := templ.Execute(w, data)
if err != nil {
log.Println(err)
}
}
func main() {
loadTemplate()
}
BuildTemplate looks like:
func BuildTemplate(dir string, funcMap template.FuncMap) (*template.Template, error) {
fs, err := ioutil.ReadDir(dir)
if err != nil {
fmt.Printf("Can't read template folder: %s\n", dir)
return nil, err
}
files := make([]string, len(fs))
for i, f := range (fs) {
files[i] = path.Join(dir, f.Name())
}
return template.Must(template.New("Template").Funcs(funcMap).ParseFiles(files...)), nil
}
