summary

A light go web framework. Most of the functional components are implemented by interfaces.

Support custom execution nodes and Middleware.

Boy framework like and demo, Defined some alias global variables, easy to use.

You can as soo as possible organize a smaller or bigger framework using the corresponding packages.

The ultimate goal of writing this:

1 The framework can be as large or as small as possible to customize and modify most components.

2 Highly configurable. You can easily deploy multiple services on one machine. Independent of system environment variables

Installation

To install boy framework, you should install Go first.

Go required 1.14+

go get -u github.com/slclub/boy 

If you use "go mod" to manager your project. just import the packeage.

import "github.com/slclub/boy"

If you want to use the latest code. please change to latest version in the go.mod file.

require ( github.com/slclub/boy latest )

Quick start

package main import ( "github.com/slclub/boy" "github.com/slclub/gnet" ) func main() { boy.R.GET("/example/ping", func(this gnet.Contexter) { this.Response().WriteString("Hello World!") }) boy.Run() }

This benchmark results come from gcore bench testing.

Configration

Install from boy.Install()

Config file template

If there is no config file. It will automaticlly generate one.

You don't have to worry about it.

Router

Import from grouter

  • Restfull router added.
boy.R. GET(url string, ctx gnet.HandleFunc) POST(url string, ctx gnet.HandleFunc) PUT(url string, ctx gnet.HandleFunc) DELETE(url string, ctx gnet.HandleFunc) PATCH(url string, ctx gnet.HandleFunc) HEAD(url string, ctx gnet.HandleFunc) OPTIONS(url string, ctx gnet.HandleFunc) // can accept any http.Method request. ANY(url string, ctx gnet.HandleFunc)
  • Use Group
//  boy.R.Group(func(group grouter.IGroup){ // add this group routes a middlerware. group.Use(func(ctx gnet.Contexter) {}) // Deny a middlerware for these routes. group.Deny(gnet.HandleFunc) boy.R.GET(url string, ctx gnet.HandleFunc) boy.R.POST(url string, ctx gnet.HandleFunc) ...	})
  • Use Defined code handle, 404, 405,500;
boy.R.BindCodeHandle(404, gnet.HandleFunc) boy.R.BindCodeHandle(405, gnet.HandleFunc) ...

Context

gnet.Contexter

Request

Request object. Obtain all kinds of requested information and parameter routes in the object here

Source Code, You can read it from this link.

Request Paramters

You can use these methods get paramters from path param, query, form, and so on.

You don't care about where the paramters come from.

type RequestParameter interface { // Get param inetface ---------------------------------------------------------- // just get string by key string. // q=a // return a GetString(key string, args ...string) (value string, ret bool) // q[]=a&q[]=b // return []string{a, b} GetArray(key string, args ...[]string) ([]string, bool) // q[a]=a&q[b]=b // return map[string]string{"a":"a", "b":"b"} GetMapString(key string, args ...map[string]string) (map[string]string, bool) GetInt64(key string, args ...int64) (int64, bool) GetInt(key string, args ...int) (int, bool) // set SetParam(key, value string) // input :// data BodyByte() ([]byte, error) }
// example boy.R.GET(url, func(ctx gnet.Contexter){ s1, ok := ctx.Request().GetString(key, default_value string)	})
Request Interface
type IRequest interface { GetHttpRequest() *http.Request RequestParameter // init and reset InitWithHttp(*http.Request) Reset() // header GetHeader(key string) string ContentType(args ...bool) string GetRemoteAddr() string //file FormFile(key string) (*multipart.FileHeader, error) }
// example boy.R.GET(url, func(ctx gnet.Contexter){ s1 := ctx.Request().ContentType()	})

Response

Rewrite the interface of http.ResponseWriter.

type IResponse interface {	http.ResponseWriter	http.Hijacker	http.Flusher	http.CloseNotifier // Returns the HTTP response status code of the current request. Status() int // Returns the number of bytes already written into the response http body. // See Written() Size() int // Writes the string into the response body. WriteString(string) (int, error) // Returns true if the response body was already written. Written() bool // Forces to write the http header (status code + headers). FlushHeader() // get the http.Pusher for server push Pusher() http.Pusher // init reset Reset() InitSelf(http.ResponseWriter) // update ResponseWriter.Header() Headers(key, value string) }
// example boy.R.GET(url, func(ctx gnet.Contexter){ ctx.Response().Write([]bytes{"hello girls"}) ctx.Response().WriteString("hello girls")	})

Contexter Api

Source Code

These methods been used in the same way.

 // example boy.R.GET(url, func(ctx gnet.Contexter){ ctx.Xxx(args ...) })
Reset() // gerror.StackError([]error) support: // Push(err error) // Pop() error // Size() int GetStackError() gerror.StackError SetSameSite(st http.SameSite) ClientIP() string // GetHandler() HandleFunc SetHandler(HandleFunc) GetExecute() Executer SetExecute(exe Executer) //redirect Redirect(location string, args ...int)
Contexter Setter Getter

For custome key-value pairs extension.

type SetterGetter interface { // setter Set(key string, val interface{}) // getter Get(key string) (interface{}, bool) GetString(key string) string GetInt(key string) int GetInt64(key string) int64 }
Contexter Get Set Request
// request from other place. type IContextRequest interface { Request() IRequest SetRequest(IRequest) bool // cookie SetCookie(name, value string, args ...interface{}) Cookie(string) (string, error) // echo data to response writer. Data(map[string]interface{})gnet.Contexter Echo(args...string) }
Contexter Get Set Response
// response to client or other server. type IContextResponse interface { Response() IResponse SetResponse(IResponse) bool }
Contexter Abort

Execution process jump control.

// interrupt interface. type Aborter interface { // abort current handle . Abort() AbortStatus(int) // Jump out of the whole execution process. // break whole work flow. Exit() }

Save File

Upload file.

f1 = func(ctx gnet.Contexter) { f, err := ctx.Request().FormFile("file") gnet.SaveUploadFile(f, "/tmp/glog/test") }

MiddlerWare

Tutorials

Source Code. You can use or deny any flow node or url handle middlerware.

No matter where the middleware is used.

  • interface
type Middler interface { // public excuter interface.	flow.IExecuteNode // middle ware interface Use(gnet.HandleFunc) Deny(gnet.HandleFunc) GetHandle(i int) (gnet.HandleFunc, string) Combine(Middler) Size() int }
  • Use Deny
example: mf1 := func(ctx gnet.Contexter){} mf2 := func(ctx gnet.Contexter){} mf3 := func(ctx gnet.Contexter){} // public before node use or deny middlerware. boy.MiddlerBefore.Use(mf1) boy.MiddlerBefore.Use(mf2) // The url1 handle will only execute the first gnet.HandleFunc.  // flow: mf1(ctx), handle boy.R.Deny(mf2) boy.R.GET(url1, func(ctx gnet.Contexter){}) // The url2 will execute boths handles. // flow: mf1(ctx), mf2(ctx), mf3(ctx) handle boy.R.Use(mf3) boy.R.GET(url2, func...) // after node use or deny middlerware. boy.MiddlerAfter.Use ...
  • Group Router Use Deny

Router Group use or deny middlerware.

example: mf1 := func(ctx gnet.Contexter){} mf2 := func(ctx gnet.Contexter){} mf3 := func(ctx gnet.Contexter){} boy.MiddlerBefore.Use(f1) boy.MiddlerBefore.Use(f2) // These routes of group have to same flow way. // flow: mf1(ctx), mf3(ctx) , handle, mf5(ctx) boy.R.Group(func(group grouter.IGroup){ group.Deny(mf2) group.Use(mf3) group.Deny(mf4) boy.R.GET(url1, gnet.HandleFunc) boy.R.GET(url2, gnet.HandleFunc) boy.R.GET(url3, gnet.HandleFunc)	}) mf4 := func(ctx gnet.Contexter){} mf5 := func(ctx gnet.Contexter){} boy.MiddlerAfter.Use(f4) boy.MiddlerAfter.Use(f5) 

Third Middlewares

Static

Static service listening

You just need to change the file of etc/go.ini

# static service setting. [static_service] # Static root path. # Default value is empty # If you set the value of this field. It should be an absoluted path. root= # example:  # Listening to multiple static folders needs to be separated by backspaces service=sa sb # param @1 aliase of static path that is used to url. # @2 actual floder path. # @3 folder listing. true,on,yes,false; Where can browse directories. sa=source source true sb=static assets true

Custom

  • Rewrite router

Example : Just implement the github.com/slclub/gouter.Router, if you want to rewrite router.

// examples: func NewRouter() grouter.Router { r := &router{} r.initself(grouter.NewRouter()) //r.SetStore(grouter.NewStore()) //r.SetDecoder(grouter.NewPath()) //r.code_handles = make(map[int]gnet.HandleFunc) //bind code handle r.BindCodeHandle(http.StatusNotFound, func(ctx gnet.Contexter) { ctx.Response().WriteHeader(404) ctx.Response().WriteString("grouter 404 not found") }) r.NotFoundHandler = func(w http.ResponseWriter, r *http.Request) { w.WriteHeader(404) w.Write([]byte("grouter 404 not found")) } //http.StatusMethodNotAllowed //r.BindCodeHandle(http.StatusMethodNotAllowed, grouter.http_405_handle) //r.BindCodeHandle(http.StatusInternalServerError, grouter.http_500_handle) return r } type router struct { grouter.Router NotFoundHandler func(http.ResponseWriter, *http.Request) } func (r *router) initself(rr grouter.Router) { r.Router = rr } router := NewRouter() router.SetKey("router") boy.App.DriverRegister(router)
