基于原生Go語(yǔ)言開(kāi)發(fā)一個(gè)博客系統(tǒng)

更新時(shí)間：2024年02月28日 10:50:18 作者：lucky九年

這篇文章主要為大家詳細(xì)介紹了如何基于原生Go語(yǔ)言開(kāi)發(fā)一個(gè)簡(jiǎn)單的博客系統(tǒng),文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

1. 搭建項(xiàng)目

package main

import (
	"encoding/json"
	"log"
	"net/http"
)

type IndexData struct {
	Title string `json:"title"`
	Desc string `json:"desc"`
}
func index(w http.ResponseWriter,r *http.Request)  {
	w.Header().Set("Content-Type","application/json")
	var indexData IndexData
	indexData.Title = "碼神之路go博客"
	indexData.Desc = "現(xiàn)在是入門(mén)教程"
	jsonStr,_ := json.Marshal(indexData)
	w.Write(jsonStr)
}

func main()  {
	//程序入口，一個(gè)項(xiàng)目 只能有一個(gè)入口
	//web程序，http協(xié)議 ip port
	server := http.Server{
		Addr: "127.0.0.1:8080",
	}
	http.HandleFunc("/",index)
	if err := server.ListenAndServe();err != nil{
		log.Println(err)
	}
}

2. 響應(yīng)頁(yè)面

func indexHtml(w http.ResponseWriter,r *http.Request)  {
	t := template.New("index.html")
	viewPath, _ := os.Getwd()
	t,_ = t.ParseFiles(viewPath + "/template/index.html")
	var indexData IndexData
	indexData.Title = "碼神之路go博客"
	indexData.Desc = "現(xiàn)在是入門(mén)教程"
	err := t.Execute(w,indexData)
	fmt.Println(err)
}

func main()  {
	//程序入口，一個(gè)項(xiàng)目 只能有一個(gè)入口
	//web程序，http協(xié)議 ip port
	server := http.Server{
		Addr: "127.0.0.1:8080",
	}
	http.HandleFunc("/",index)
	http.HandleFunc("/index.html",indexHtml)
	if err := server.ListenAndServe();err != nil{
		log.Println(err)
	}
}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
 hello mszlu blog!!
{{.Title}}
 {{.Desc}}
</body>
</html>

3. 首頁(yè)

3.1 頁(yè)面解析

func index(w http.ResponseWriter,r *http.Request)  {
	var indexData IndexData
	indexData.Title = "碼神之路go博客"
	indexData.Desc = "現(xiàn)在是入門(mén)教程"
	t := template.New("index.html")
	//1. 拿到當(dāng)前的路徑
	path,_ := os.Getwd()
	//訪問(wèn)博客首頁(yè)模板的時(shí)候，因?yàn)橛卸鄠€(gè)模板的嵌套，解析文件的時(shí)候，需要將其涉及到的所有模板都進(jìn)行解析
	home := path + "/template/home.html"
	header := path + "/template/layout/header.html"
	footer := path + "/template/layout/footer.html"
	personal := path + "/template/layout/personal.html"
	post := path + "/template/layout/post-list.html"
	pagination := path + "/template/layout/pagination.html"
	t,_ = t.ParseFiles(path + "/template/index.html",home,header,footer,personal,post,pagination)

	//頁(yè)面上涉及到的所有的數(shù)據(jù)，必須有定義
	t.Execute(w,indexData)
}

3.2 首頁(yè)數(shù)據(jù)格式定義

5. 假數(shù)據(jù)-顯示首頁(yè)內(nèi)容

func index(w http.ResponseWriter,r *http.Request)  {
	t := template.New("index.html")
	//1. 拿到當(dāng)前的路徑
	path := config.Cfg.System.CurrentDir

	//頁(yè)面上涉及到的所有的數(shù)據(jù)，必須有定義
	var categorys = []models.Category{
