unrolled/render 集成Masterminds/sprig 增强模版处理

作者：互联网

Masterminds/sprig 是一个强大的golang 模版函数，以下是一个unrolled/render 集成Masterminds/sprig 的简单demo

环境准备

module github.com/rongfengliang/renameio-app
​
go 1.14
​
require (
    github.com/Masterminds/goutils v1.1.0 // indirect
    github.com/Masterminds/semver v1.5.0 // indirect

golang 代码集成

package main
​
import (
    "encoding/xml"
    "errors"
    "html/template"
    "net/http"
​
    "github.com/Masterminds/sprig"
    "github.com/google/renameio"
    "github.com/unrolled/render"
)
​
// fielname for test
func filname() error {
    confContent := `
    nginx {
        main {
            server {
                port :9090;
            }
        }
    }
    `
    err := renameio.WriteFile("./demo.conf", []byte(confContent), 0644)
    if err != nil {
        return errors.New("some wrong:" + err.Error())
    }
    return nil
}
​
// render demo
func main() {
​
    r := render.New(render.Options{
        Layout:        "layout",
        IsDevelopment: true,
        Funcs: []template.FuncMap{
            sprig.FuncMap(),
        },
    })
    mux := http.NewServeMux()
    mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
        w.Write([]byte("Welcome, visit sub pages now."))
    })
    ob := struct {
        XMLName xml.Name `json:"-" xml:"dalongdemoapp"`
        Name    string   `json:"dalongrong" xml:"dalongdemo"`
        Items   []string `json:"items" xml:"items"`
    }{
        Name:  "dalong",
        Items: []string{"demo", "app"},
    }
    mux.HandleFunc("/json", func(w http.ResponseWriter, req *http.Request) {
        r.JSON(w, 200, ob)
    })
    mux.HandleFunc("/xml", func(w http.ResponseWriter, req *http.Request) {
        r.XML(w, 200, ob)
    })
    mux.HandleFunc("/rename", func(w http.ResponseWriter, req *http.Request) {
        if err := filname(); err != nil {
            r.JSON(w, 500, "rename wrong")
            return
        }
        r.JSON(w, 200, "rename ok")
​
    })
    mux.HandleFunc("/html", func(w http.ResponseWriter, req *http.Request) {
        r.HTML(w, 200, "index", ob)
    })
    http.ListenAndServe("127.0.0.1:3000", mux)
}

集成模版函数的demo

 

 

说明

以上只是一个简单的集成，实际上sprig 还是很强大的，helm就集成了此模块
效果
