# YoyoGo 特色
- 漂亮又快速的路由器 & MVC 模式 .
- 丰富的中间件支持 (handler func & custom middleware) .
- 微服务框架抽象了分层，在一个框架体系兼容各种server实现，如 rest,grpc等 .
- 充分运用依赖注入DI，管理运行时生命周期，为框架提供了强大的扩展性 .
- 功能强大的微服务集成能力 (Nacos, Eureka, Consul, ETCD) .
- 受到许多出色的 Go Web 框架的启发，并实现了多种 server : **fasthttp** 和 **net.http** 和 **grpc** .

# 框架安装
```bash
go get github.com/yoyofx/yoyogo
```
# 安装依赖 (由于某些原因国内下载不了依赖)
##  go version < 1.20
```bash
window 下在 cmd 中执行：
set GO111MODULE=on
set GOPROXY=https://goproxy.cn,direct
linux  下执行：
export GO111MODULE=on
export GOPROXY=https://goproxy.cn,direct
```
##  go version >= 1.13
```
go env -w GOPROXY=https://goproxy.cn,direct
```
### vendor
```
go mod vendor       // 将依赖包拷贝到项目目录中去
```
# 简单的例子
```golang
package main
import ...

func main() {
	WebApplication.CreateDefaultBuilder(func(rb router.IRouterBuilder) {
        rb.GET("/info",func (ctx *context.HttpContext) {    // 支持Group方式
            ctx.JSON(200, context.H{"info": "ok"})
        })
    }).Build().Run()       //默认端口号 :8080
}
```

# 进阶范例

```golang

			app.UseMvc(func(builder *mvc.ControllerBuilder) {
				//builder.AddViews(&view.Option{Path: "./static/templates"})
				builder.AddViewsByConfig()
				builder.AddController(contollers.NewUserController)
				builder.AddFilter("/v1/user/info", &contollers.TestActionFilter{})
			})
		}).
		ConfigureServices(func(serviceCollection *dependencyinjection.ServiceCollection) {
			serviceCollection.AddTransientByImplements(models.NewUserAction, new(models.IUserAction))
