go-render
This project is written by golang. Easily rendering serialized JSON, XML, and HTML template responses use http.ResponseWriter. It's migration from 'github.com/martini-contrib/render'
Usage
package main
import (
"html/template"
"net/http"
"time"
"github.com/gin-gonic/gin"
"gitera.cn/ron/go-render"
)
func main() {
var funcMap = template.FuncMap{
"Add": func(l, r int) int { return l + r },
"FormatTime": func(t time.Time, str string) string { return util.NewDate().Format(t, str) },
}
// 初始化render
render.Render(render.Options{
Directory: "templates", // Specify what path to load the templates from.
Layout: "layout", // Specify a layout template. Layouts can call {{ yield }} to render the current template.
Extensions: []string{".tmpl", ".html"},// Specify extensions to load for templates.
Delims: render.Delims{"{{", "}}"}, // Sets delimiters to the specified strings.
Charset: "UTF-8", // Sets encoding for json and html content-types. Default is "UTF-8".
IndentJSON: true, // Output human readable JSON
IndentXML: true, // Output human readable XML
FuncMap: funcMap, // Functions add to template
HTMLContentType: render.ContentHTML, // Output XHTML content type instead of default "text/html"
})
r := gin.Default()
// 添加路由
r.GET("/", func(ctx *gin.Context) {
// 设置参数
d := map[string]template.HTML{
"Title": "登陆",
}
// 渲染HTML
render.HTML(ctx.Writer, 200, "index", d)
})
// 设置http服务
s := &http.Server{
Addr: ":8080",
Handler: r,
ReadTimeout: 30 * time.Second,
WriteTimeout: 30 * time.Second,
MaxHeaderBytes: 1 << 20,
}
s.ListenAndServe()
}
The following templates:
<!-- templates/layout.tmpl -->
<!doctype html>
<html lang="zh">
<head>
<title>{{.Title}}</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link rel="shortcut icon" type="image/x-icon" href="/favicon.ico" />
</head>
<body>
<!-- Render the current template here -->
{{ yield }}
</body>
</html>
<!-- templates/index.tmpl -->
<h1>{{.Name}}</h1>
<ul>
<li>{{template "base/header"}}</li>
</ul>
<!-- templates/base/header.tmpl -->
<h2>我是头</h2>

Functions ¶
func Data ¶
func Data(w http.ResponseWriter, status int, v []byte)
func Error ¶
func Error(w http.ResponseWriter, status int, v []byte)
Error writes the given HTTP status to the current ResponseWriter
func HTML ¶
func HTML(w http.ResponseWriter, status int, name string, binding interface{}, htmlOptions ...HTMLOptions)
func Init ¶
func Init(o Options)
Init is a external rendering. An single variadic render.Options struct can be optionally provided to configure HTML rendering. The default directory for templates is "templates" and the default file extension is ".tmpl".
func JSON ¶
func JSON(w http.ResponseWriter, status int, v interface{})
func Status ¶
func Status(w http.ResponseWriter, status int)
func Text ¶
func Text(w http.ResponseWriter, status int, v string)
func XML ¶
func XML(w http.ResponseWriter, status int, v interface{})
Types ¶
type Delimiter ¶
type Delimiter struct {
// Left delimiter, defaults to {{
Left string `yaml:"Left"`
// Right delimiter, defaults to }}
Right string `yaml:"Right"`
}
Delimiter represents a set of Left and Right delimiters for HTML template rendering
type HTMLOptions ¶
type HTMLOptions struct {
// Layout template name. Overrides Options.Layout.
Layout string
}
HTMLOptions is a struct for overriding some rendering Options for specific HTML call
type Options ¶
type Options struct {
// Directory to load templates. Default is "templates"
Directory string `yaml:"Directory"`
// Layout template name. Will not render a layout if "". Defaults to "".
Layout string `yaml:"Layout"`
// Extensions to parse template files from. Defaults to [".tmpl"]
Extensions []string `yaml:"Extensions"`
// Funcs is a slice of FuncMap to apply to the template upon compilation. This is useful for helper functions. Defaults to [].
FuncMap template.FuncMap `yaml:"FuncMap"`
// Delimiter sets the action delimiters to the specified strings in the Delimiter struct.
Delimiter Delimiter `yaml:"Delimiter"`
// Appends the given charset to the Content-Type header. Default is "UTF-8".
Charset string `yaml:"Charset"`
// Outputs human readable JSON
IndentJSON bool `yaml:"IndentJSON"`
// Outputs human readable XML
IndentXML bool `yaml:"IndentXML"`
// Prefixes the JSON output with the given bytes.
PrefixJSON []byte `yaml:"PrefixJSON"`
// Prefixes the XML output with the given bytes.
PrefixXML []byte `yaml:"PrefixXML"`
// Allows changing of output to XHTML instead of HTML. Default is "text/html"
HTMLContentType string `yaml:"HTMLContentType"`
// Initial BufferPool cap
BufferPool int `yaml:"BufferPool"`
// Set template in debug mode to refresh template.
DebugMode bool `yaml:"DebugMode"`
}
Options is a struct for specifying configuration options for the render.Init middleware
