生命不止，繼續 go go go !!!
先來一點小小的插曲，部落格關於go的uv量：
今天，跟大家一起學習分享的是在golang中如何使用markdown文法，當然是使用第三方庫了russross/blackfriday。
參考：http://blog.will3942.com/creating-blog-go
Markdown是一種可以使用普通文字編輯器編寫的標記語言，通過簡單的標記文法，它可以使普通常值內容具有一定的格式。
Markdown具有一系列衍生版本，用於擴充Markdown的功能（如表格、腳註、內嵌HTML等等），這些功能原初的Markdown尚不具備，它們能讓Markdown轉換成更多的格式，例如LaTeX，Docbook。Markdown增強版中比較有名的有Markdown Extra、MultiMarkdown、 Maruku等。這些衍生版本要麼基於工具，如Pandoc；要麼基於網站，如GitHub和Wikipedia，在文法上基本相容，但在一些文法和渲染效果上有改動
這裡怒推一款好用的markdown編輯軟體：

也是在golang中，最有名的吧
Blackfriday: a markdown processor for Go
watch:72
star:2591
fork:328
Blackfriday is a Markdown processor implemented in Go. It is paranoid about its input (so you can safely feed it user-supplied data), it is fast, it supports common extensions (tables, smart punctuation substitutions, etc.), and it is safe for all utf-8 (unicode) input.
一個簡單的server
package mainimport ( "fmt" "net/http")func handlerequest(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hi i am SuperWang %s", r.URL.Path[1:])}func main() { http.HandleFunc("/", handlerequest) http.ListenAndServe(":8000", nil)}使用template
關於如何使用html/template，請參考部落格：
Go語言學習之html/template包(The way to go)
index.html:
<html> <body> <h1>SuperWang's Blog!</h1> <p>{{.}}</p> </body></html>package mainimport ( "html/template" "net/http")func handlerequest(w http.ResponseWriter, r *http.Request) { title := "Hello Golang World!" t := template.New("index.html") t, _ = t.ParseFiles("index.html") t.Execute(w, title)}func main() { http.HandleFunc("/", handlerequest) http.ListenAndServe(":8000", nil)}讀取markdown檔案
index.html修改為：
<html> <body> <h1>SuperWang's Blog!</h1> {{range .}} <a href="/{{.File}}"><h2>{{.Title}} ({{.Date}})</h2></a> <p>{{.Summary}}</p> {{end}} </body></html>md檔案，姑且命名為test.md:
First post!8/9/2017This is the summary.This is the main post!# Markdown!*it's* **golang**!main.go:
package mainimport ( "html/template" "io/ioutil" "net/http" "path/filepath" "strings" "github.com/russross/blackfriday")type Post struct { Title string Date string Summary string Body string File string}func handlerequest(w http.ResponseWriter, r *http.Request) { posts := getPosts() t := template.New("index.html") t, _ = t.ParseFiles("index.html") t.Execute(w, posts)}func getPosts() []Post { a := []Post{} files, _ := filepath.Glob("posts/*") for _, f := range files { file := strings.Replace(f, "posts/", "", -1) file = strings.Replace(file, ".md", "", -1) fileread, _ := ioutil.ReadFile(f) lines := strings.Split(string(fileread), "\n") title := string(lines[0]) date := string(lines[1]) summary := string(lines[2]) body := strings.Join(lines[3:len(lines)], "\n") body = string(blackfriday.MarkdownCommon([]byte(body))) a = append(a, Post{title, date, summary, body, file}) } return a}func main() { http.HandleFunc("/", handlerequest) http.ListenAndServe(":8000", nil)}Start building with 50+ products and up to 12 months usage for Elastic Compute Service
