HTML渲染

使用LoadHTMLGlob() 或者 LoadHTMLFiles()

func main() {
router := gin.Default()
router.LoadHTMLGlob("templates/*")
//router.LoadHTMLFiles("templates/template1.html", "templates/template2.html")
router.GET("/index", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.tmpl", gin.H{
"title": "Main website",
})
})
router.Run(":8080")
}

templates/index.tmpl



<html>
<h1>
{{ .title }}
</h1>
</html>

在不同目录中使用具有相同名称的模板

func main() {
router := gin.Default()
router.LoadHTMLGlob("templates/**/*")
router.GET("/posts/index", func(c *gin.Context) {
c.HTML(http.StatusOK, "posts/index.tmpl", gin.H{
"title": "Posts",
})
})
router.GET("/users/index", func(c *gin.Context) {
c.HTML(http.StatusOK, "users/index.tmpl", gin.H{
"title": "Users",
})
})
router.Run(":8080")
}

templates/posts/index.tmpl

{{ define "posts/index.tmpl" }}
<html><h1>
{{ .title }}
</h1>
<p>Using posts/index.tmpl</p>
</html>
{{ end }}
templates/users/index.tmpl

{{ define "users/index.tmpl" }}
<html><h1>
{{ .title }}
</h1>
<p>Using users/index.tmpl</p>
</html>
{{ end }}

自定义模板渲染器

import "html/template"

func main() {
router := gin.Default()
html := template.Must(template.ParseFiles("file1", "file2"))
router.SetHTMLTemplate(html)
router.Run(":8080")
}
自定义渲染分隔符

r := gin.Default()
r.Delims("{[{", "}]}")
r.LoadHTMLGlob("/path/to/templates")

自定义模板函数

详细信息

main.go

import (
"fmt"
"html/template"
"net/http"
"time"

"github.com/gin-gonic/gin"
)

func formatAsDate(t time.Time) string {
year, month, day := t.Date()
return fmt.Sprintf("%d%02d/%02d", year, month, day)
}

func main() {
router := gin.Default()
router.Delims("{[{", "}]}")
router.SetFuncMap(template.FuncMap{
"formatAsDate": formatAsDate,
})
router.LoadHTMLFiles("./testdata/template/raw.tmpl")

router.GET("/raw", func(c *gin.Context) {
c.HTML(http.StatusOK, "raw.tmpl", map[string]interface{}{
"now": time.Date(2017, 07, 01, 0, 0, 0, 0, time.UTC),
})
})

router.Run(":8080")
}

raw.tmpl

然后就可以在html中直接使用formatAsDate函数了

Date: {[{.now | formatAsDate}]}

Result:

Date: 2017/07/01
