如何在HTML文件中编写Golang代码(Gin Gonic框架)

Im newbie in golang code as well as in gin gonic. I got a problem while using gin gonic.

In my controller. i get all articles and render to html file by code.

c.HTML(http.StatusOK, "articles/list", gin.H{
    "title":    "Articles",
    "articles": articles,
})

and articles have field "CreatedOn" type int64 (created date) So in my view list.html, how i can parse CreateOn type int64 to date format.

<div class="list-group">
  {{ range $article := $articles }}
    <a href="/articles/{{ $article.Id }}" class="list-group-item">
      <h4 class="list-group-item-heading">{{ $article.Title }}</h4>
      <p class="list-group-item-text">{{ $article.Body }}</p>
      <p class="list-group-item-text">{{ $article.CreatedOn  }}</p>
      <p class="list-group-item-text"></p>
    </a>
  {{ end }}
  </div>

Thanks all

I had found a way that i write a method FormatDate()

func (a *Article) FormatDate(ab int64) string {
    return "test Time"
}

in model "Article". then in my view i call

  <p class="list-group-item-text">{{ .FormatDate article.CreatedOn  }}</p>

Anything else????

    TL;DR use SetHTMLTemplate

    Looking at the Gin documentation, you can use your own templating engine.

    By invoking r.SetHTMLTemplate(tmpl)

    Gin itself is using the golang builtin html/template standard package.

    You can use the same engine and add user defined functions.

    Create the functions, using template.FuncMap:

    funcMap := template.FuncMap{
        "formatTime": func(raw int64) string {
            t := time.Unix(raw, 0)
    
            return t.Format("Jan 2 15:04:05 2006")
        },
    }
    

    Instantiate a template:

    tmpl := template.Must(template.New("main").Funcs(funcMap).ParseGlob("templates/**/*"))
    

    Register the new template:

    r := gin.Default()
    r.SetHTMLTemplate(tmpl)
    

    If you use same templates name for different endpoints, specify name:

    {{ define "articles/list.tmpl"}}
    
    <div class="list-group">
    {{ range $article := .articles }}
      <a href="/articles/{{ $article.Id }}" class="list-group-item">
        <h4 class="list-group-item-heading">{{ $article.Title }}</h4>
        <p class="list-group-item-text">{{ formatTime $article.CreatedOn }}</p>
        <p class="list-group-item-text"></p>
      </a>
    {{ end }}
    </div>
    
    {{ end }}
    

    formatTime: Is defined using template.FuncMap

    To invoke, use the normal way:

    c.HTML(http.StatusOK, "articles/list", gin.H{
        "title":    "Articles",
        "articles": articles,
    })
