# Boy framework
[源码](https://github.com/slclub/boy)
[English](https://github.com/slclub/boy/blob/master/README.md) [中文](https://github.com/slclub/boy/blob/master/README.ch.md)
## 概述
一个轻型的go web 框架。80% 的代码都是用接口实现的。支持自定义执行节点 以及中间件。
这个Boy 框架 像是是一个demo，仅仅是定义一些别名简写方便使用，定义了一些执行节点。
您也可以迅速的用它重写一个属于自己的框架。可重可轻，不过需要知道相关的几个包都是
做什么的，以及如何使用他们。
通过ini配置文件我们可以 同时监听http 和 https 甚至是websocket, 以及静态服务配置等
比较工程化。
通过这些年的工作，一个可伸缩的框架才是我理想中的框架。所以我们此框架最终主要为了
以下几点：
1 伸缩性：框架具有伸缩性，可重，可轻，满足不同的需求。
2 可变：框架可以根据不同配置参数适当的变化运行方式，不需要再去改框架代码。减少依赖和修改源码。
3 简洁:更为简洁统一的写法，很多时候不必关系内部处理。
4 最小重写：当重写时尽可能的少写代码，仅改需要改的部分即可。
## 安装
你需要先安装go 环境。暂时还没有做docker 支持
Go 版本 1.14+
```ssh

If there is no config file. It will automaticlly generate one.
You don't have to worry about it.
### Router
Import from [grouter](https://github.com/slclub/grouter)
- Restfull router added.
```go
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
```go
//
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;
```go
boy.R.BindCodeHandle(404, gnet.HandleFunc)
boy.R.BindCodeHandle(405, gnet.HandleFunc)
...
```
- [group.Router interface](https://github.com/slclub/grouter/blob/master/irouter.go)
### Context
[gnet.Contexter](https://github.com/slclub/gnet)
#### Request
Request object. Obtain all kinds of requested information and parameter routes in the object here
[Source Code](https://github.com/slclub/gnet/blob/master/request.go), 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.
```go
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)
}
```
```go
// example
boy.R.GET(url, func(ctx gnet.Contexter){
s1, ok := ctx.Request().GetString(key, default_value string)
})
```
##### Request Interface
```go
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)
}
```
```go
// example
boy.R.GET(url, func(ctx gnet.Contexter){
s1 := ctx.Request().ContentType()
})
```
#### Response
Rewrite the interface of http.ResponseWriter.
```go
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)
}
```
```go
// example
boy.R.GET(url, func(ctx gnet.Contexter){
ctx.Response().Write([]bytes{"hello girls"})
ctx.Response().WriteString("hello girls")
})
```
#### Contexter Api
[Source Code](https://github.com/slclub/gnet/blob/master/context.go)
These methods been used in the same way.
```go
// example
boy.R.GET(url, func(ctx gnet.Contexter){
ctx.Xxx(args ...)
})
```
```go
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.
```go
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
```go
// request from other place.
type IContextRequest interface {
Request() IRequest
SetRequest(IRequest) bool
// cookie
SetCookie(name, value string, args ...interface{})
Cookie(string) (string, error)
}
```
##### Contexter Get Set Response
```go
// response to client or other server.
type IContextResponse interface {
Response() IResponse
SetResponse(IResponse) bool
}
```
##### Contexter Abort
Execution process jump control.
```go
// 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.
```go
f1 = func(ctx gnet.Contexter) {
f, err := ctx.Request().FormFile("file")
gnet.SaveUploadFile(f, "/tmp/glog/test")
}
```
### MiddlerWare
[Source Code](https://github.com/slclub/gcore/blob/master/execute/middleware.go). You can use or deny any flow node or url handle middlerware.
No matter where the middleware is used.
- interface
```go
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
```go
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.
```go
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)
```
### Static
Static service listening
You just need to change the file of etc/go.ini
```go
# 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](https://github.com/slclub/grouter), if you want to rewrite router.
```go
// 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)
```
