(1):总重复次数达到的时间越长,意味着越有信心的结果
(2):单次重复持续时间(ns / op),越低越好
(3):堆内存(B / op),越低越好
(4):每个重复的平均分配(分配/操作),越低越好
零分配路由器。
仍然是最快的http路由器和框架。从路由到写作。
完整的单元测试套件
测试战斗
API冻结,新版本不会破坏你的代码。
下载并安装它
1 | gogetgithub.com/gin-gonic/gin |
在你的代码中导入它:
1 | import"github.com/gin-gonic/gin" |
(可选)导入net/http
。例如,如果使用常量如http.StatusOK
。
1 | import"net/http" |
go get
govendor
1 | $gogetgithub.com/kardianos/govendor |
创建你的项目文件夹cd
到里面
1 | $mkdir-p$GOPATH/src/github.com/myusername/project&&cd"$_" |
Vendor init your project and add gin
1 2 | $govendorinit $govendorfetchgithub.com/gin-gonic/gin@v1.2 |
在项目中复制起始模板
1 | $curlhttps://raw.githubusercontent.com/gin-gonic/gin/master/examples/basic/main.go > main.go |
Run your project
1 | $gorunmain.go |
