转到：在模板文件中打印URI（echo框架）

I'm using echo framework. I'm stuck when trying to print URI :mynumber as variable in template files.

All variable working fine except the URI :mynumber. I have no idea how to include :mynumber together with Name & Age

Below is my server.go:

package main

import (
    "github.com/labstack/echo"
    "html/template"
    "io"
    "net/http"
)

type Person struct {
    Name, Age, Mynumber string
}

type (
    Template struct {
        templates *template.Template
    }
)

func (t *Template) Render(w io.Writer, name string, data interface{}) error {
    return t.templates.ExecuteTemplate(w, name, data)
}

func main() {
    e := echo.New()

    p := Person{Name: "Mike San", Age: "35"}

    t := &Template{
        templates: template.Must(template.ParseFiles("public/views/testhere.html")),
    }
    e.Renderer(t)

    e.Get("/testing/:mynumber", func(c *echo.Context) {
        c.Render(http.StatusOK, "onlytestingtpl", p)
    })

    e.Run(":4444")
}

Below is public/views/testhere.html:

{{define "onlytestingtpl"}}My name is {{.Name}}. I'm {{.Age}} years old. My number is {{.Mynumber}}.{{end}}

For your reference, below is example is print URI without template file:

package main

import (
    "github.com/labstack/echo"
    "net/http"
)

func main() {
    e := echo.New()

    e.Get("/users/:id", func(c *echo.Context) {
        id := c.Param("id")
        c.String(http.StatusOK, "My number is "+id)
    })

    e.Run(":4444")
}

You simply need to retrieve it from the URL as per your working sample:

number := c.Param("mynumber")

And set it on the Person instance you're passing in:

p.Mynumber = number

Which would result in:

e.Get("/testing/:mynumber", func(c *echo.Context) {
    number := c.Param("mynumber")
    p.Mynumber = number
    c.Render(http.StatusOK, "onlytestingtpl", p)
})
