英文:
Go: serve static templates
问题
我似乎无法提供静态模板服务。这是我的代码：
Go目录结构
src/github.com/sam/helloauth.gomain.go/templatessignup.html
auth.go
package main//...func homeHandler(w http.ResponseWriter, r *http.Request) {renderTemplate(w, "signup", nil)}func renderTemplate(w http.ResponseWriter, tmpl string, user *data.User) {t := template.Must(template.New("tele").ParseFiles("templates/" + tmpl + ".html"))err := t.ExecuteTemplate(w, tmpl, user)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)}}
main.go
package mainfunc main() {//...http.Handle("/templates/", http.StripPrefix("/templates/", http.FileServer(http.Dir("templates"))))//...}
signup.html
{{ define "signup" }}//html代码{{ end }}
我运行了go install github.com/sam/auth并打开了localhost:3000，但仍然出现了恐慌错误：
open templates/signup.html: no such file or directory
为什么会这样？
英文:
I can't seem to get the static templates served. Here's my code
Go Directory Structure
src/github.com/sam/helloauth.gomain.go/templatessignup.html
auth.go
package main//...func homeHandler(w http.ResponseWriter, r *http.Request) {renderTemplate(w, "signup", nil)}func renderTemplate(w http.ResponseWriter, tmpl string, user *data.User) {t := template.Must(template.New("tele").ParseFiles("templates/" + tmpl + ".html"))err := t.ExecuteTemplate(w, tmpl, user)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)}}
main.go
package mainfunc main() {//...http.Handle("/templates/", http.StripPrefix("/templates/", http.FileServer(http.Dir("templates"))))//...}
signup.html
{{ define "signup" }}//html code{{ end }}
Ran go install github.com/sam/auth and opened localhost:3000 but I still get the panic error:
open templates/signup.html: no such file or directory
WHY???

你使用的路径 - templates/ - 是相对于程序运行的位置的。如果你希望它在无论在哪里运行程序时都能正常工作，你应该使用绝对路径，比如 $GOPATH/src/github.com/sam/hello/templates/。
但这种方式也很脆弱，因为目录可能会移动，你的程序在另一台机器上可能无法运行。我建议你考虑将资源（模板）与二进制文件捆绑在一起。一个很好的方法是使用 go-bindata。
英文:
The path you use - templates/ - is relative to where the program is run. if you want it to work regardless of where you run the program, you should use an absolute path, like $GOPATH/src/github.com/sam/hello/templates/
But this is fragile too, since the directory can move, and your program will not run on another machine. I would suggest you look at bundling your assets (the templates) with the binary. A good way to do that is using go-bindata
