HTML 渲染 · Gin開發文檔

使用 LoadHTMLGlob() 或者 LoadHTMLFiles() ```go 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 <html> <h1> {{ .title }} </h1> </html> ``` 使用不同目錄下名稱相同的模板 ```go 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 ```html {{ define "posts/index.tmpl" }} <html><h1> {{ .title }} </h1> <p>Using posts/index.tmpl</p> </html> {{ end }} ``` templates/users/index.tmpl ```html {{ define "users/index.tmpl" }} <html><h1> {{ .title }} </h1> <p>Using users/index.tmpl</p> </html> {{ end }} ``` #### 自定義模板渲染器你可以使用自定義的 html 模板渲染 ```go import "html/template" func main() { router := gin.Default() html := template.Must(template.ParseFiles("file1", "file2")) router.SetHTMLTemplate(html) router.Run(":8080") } ``` #### 自定義分隔符你可以使用自定義分隔 ```go r := gin.Default() r.Delims("{[{", "}]}") r.LoadHTMLGlob("/path/to/templates") ``` #### 自定義模板功能查看詳細[示例代碼](https://github.com/gin-gonic/examples/tree/master/template)。 main.go ```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 ```sh Date: {[{.now | formatAsDate}]} ``` 結果： ```sh Date: 2017/07/01 ```
