Fancy is a simple web framework written in Go (Golang)
- Build robust and scalable RESTful APIs
- Context
- Group APIs
- Template rendering
- Extensible middleware framework
- Define middleware at group or route level
- Data binding for JSON and form payload
- Simple Centralized HTTP error handling
- Built in simple logger system
As of version v0.1.0, Fancy is available as a Go module, example
go get github.com/gongwenlong/dayanta v0.1.0
package main
import (
fancy "github.com/gongwenlong/dayanta"
"net/http"
)
func main() {
engine := fancy.New()
v1 := engine.Group("/v1")
{
v1.GET("/hello", func(c *fancy.Context) {
c.String(http.StatusOK, "hello %s, you're at %s\n", c.Query("name"), c.Path)
})
}
engine.Run(":9996")
}
静态路由
https://localhost:9996/json?username=xxxxx
engine.GET("/json", func(c *fancy.Context) {
c.JSON(http.StatusOK, fancy.H{
"username": c.Query("username"),
})
})
engine.POST("/json", func(c *fancy.Context) {
c.JSON(http.StatusOK, fancy.H{
"username": c.PostForm("username"),
})
})
动态路由
engine.GET("/hello/:name/login", func(c *fancy.Context) {
// https://localhost:9996/hello/xxx/login
c.String(http.StatusOK, "hello %s, you're at %s\n", c.Param("name"), c.Path)
})
https://localhost:9996/v1/json?username=xxxxx
v1 := engine.Group("/v1")
{
v1.GET("/json", func(c *fancy.Context) {
c.JSON(http.StatusOK, fancy.H{
"username": c.Query("username"),
})
})
}
func main() {
engine := fancy.New()
engine.Use(Logger())
v2 := r.Group("/v2")
v2.Use(Logger()) // v2 group middleware
{
v2.GET("/hello", func(c *fancy.Context) {
// https://localhost:9996/v2/hello
c.String(http.StatusOK, c.Path)
})
}
.....
}
func Logger() fancy.HandlerFunc {
return func( c *fancy.Context) {
t := time.Now()
fmt.Println("time:" , t)
c.Next()
log.Printf("[%d] %s in %v", c.StatusCode, c.Req.RequestURI, time.Since(t))
}
}engine.GET("/panic", func(c *fancy.Context) {
names := []string{"test"}
c.String(http.StatusOK, names[100])
})
https://localhost:9996/students
type student struct {
Name string
Age int8
}
func FormatAsDate(t time.Time) string {
year, month, day := t.Date()
return fmt.Sprintf("%d-%02d-%02d", year, month, day)
}
func main() {
engine := fancy.New()
engine.SetFuncMap(template.FuncMap{
"FormatAsDate": FormatAsDate,
})
engine.LoadHTMLGlob("templates/*")
stu1 := &student{Name: "long", Age: 20}
stu2 := &student{Name: "Jack", Age: 22}
engine.GET("/students", func(c *fancy.Context) {
c.HTML(http.StatusOK, "arr.tmpl", fancy.H{
"title": "fancy",
"stuArr": [2]*student{stu1, stu2},
})
})
engine.Run(":9996")
}
项目根目录新建 templates
<!-- templates/arr.tmpl -->
<html>
<body>
<p>hello, {{.title}}</p>
{{range $index, $ele := .stuArr }}
<p>{{ $index }}: {{ $ele.Name }} is {{ $ele.Age }} years old</p>
{{ end }}
</body>
</html>

engine.Static("/assets", "/Users/admin/dongfangmingzhu/static")
