我有两个 HTML 模板(login.html、signup.html)，它们都继承了(base.html)文件，问题是两个文件之一覆盖了另一个文件的标题和内容。这意味着当我转到/login/时，我会看到登录内容，但是当我转到/signup/时，我会再次看到登录内容!当我停止(login.html)扩展base.html时，/signup/向我显示注册页面的内容。
我对 Go 还很陌生，正在构建一个待办事项应用程序，所以我在这里做错了什么？
base.html:
{{define "base"}}
<!DOCTYPE html>
...
<title>{{template "title"}}</title>
...
{{template "main" .}}
...
{{end}}
登录.html:
{{template "base" .}}
{{define "title"}}Login{{end}}
{{define "main"}}
Login Now!
{{end}}
到目前为止一切正常
现在当我开始添加更多模板时:
注册.html
{{template "base" .}}
{{define "title"}}Sign Up{{end}}
{{define "main"}}
Login or miss who you love >:(
{{end}}
更新:我的 Go 代码
main.go(负责路由和可重用功能):主包
import (
"html/template"
"log"
"net/http"
"github.com/julienschmidt/httprouter"
)
var templates = template.Must(template.ParseFiles("tmpl/base.html", "tmpl/index.html", "tmpl/signup.html", "tmpl/login.html"))
func renderTemplate(w http.ResponseWriter, r *http.Request, tmpl string, data interface{}) {
err := templates.ExecuteTemplate(w, tmpl+".html", data)
if err != nil {
http.NotFound(w, r)
return
}
}
func main() {
r := httprouter.New()
r.GET("/signup/", signupHandler)
r.POST("/createUser/", createUserHandler)
r.GET("/login/", loginHandler)
log.Fatal(http.ListenAndServe(":8080", r))
}
auth.go(包含身份验证处理程序)
package main
import (
"net/http"
"github.com/julienschmidt/httprouter"
)
func signupHandler(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
renderTemplate(w, r, "signup", nil)
}
// Logins
func loginHandler(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
renderTemplate(w, r, "login", nil)
return
}

if r.FormValue("password1") != r.FormValue("password2") {

return
}
db := connectDB(w, "TodoWoo")
defer db.Close()
q := `INSERT INTO users(username, password) VALUES (?, ?)`
if _, err := db.Exec(q, r.FormValue("username"), r.FormValue("password1")); err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
http.Redirect(w, r, "/login/", http.StatusFound)
}
func loginUserHandler(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
}
driver.go(正在连接数据库，不确定这是否相关
package main
import (

)
// Don't forgot to defer db.Close()
func connectDB(w http.ResponseWriter, scm string) *sql.DB {
db, err := sql.Open("mysql", fmt.Sprintf("root:My44200444Sql@(127.0.0.1:3306)/%s?parseTime=true", scm))
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
return db
}
最佳答案
你可以这样做:
base.html
{{define "base_header"}}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{ . }}</title>
</head>
<body>
{{end}}
{{define "base_footer"}}
</body>
</html>
{{end}}
login.html
{{ $page_title := "Login" }}
{{ $page_footer := "login footer text" }}
{{ template "base_header" $page_title }}
Login Now!
{{ template "base_footer" $page_footer }}
signup.html
{{ $page_title := "Sign Up" }}
{{ $page_footer := "signup footer text" }}
{{ template "base_header" $page_title }}
Login or miss who you love >:(
{{ template "base_footer" $page_footer }}
