gin使用 swag 记录

1、go get -u github.com/swaggo/swag/cmd/swag

$ go get -u github.com/swaggo/swag/cmd/swag

报错：go 获取golang.org/x/tools包失败

go get  golang.org/x/tools/go/packages
package golang.org/x/tools/go/packages: unrecognized import path "golang.org/x/tools/go/packages" (https fetch: Get https://golang.org/x/tools/go/packages?go-get=1: proxyconnect tcp: net/http: TLS handshake timeout)

替代的解决办法就是直接去https://github.com/golang/tools.git 克隆一份然后放到E:\gopath\src[golang.org](http://golang.org/)\x\tools目录下

2、安装 gin-swagger
$ go get -u github.com/swaggo/gin-swagger

$ go get -u github.com/swaggo/gin-swagger/swaggerFiles

3、编写API注释

4、生成
进入项目根目录

[$ gin-blog]# swag init
2018/03/13 23:32:10 Generate swagger docs....
2018/03/13 23:32:10 Generate general API Info
2018/03/13 23:32:10 create docs.go at  docs/docs.go

坑爹的出现了下面的报错，然后懵逼了，从来没遇到过，后来仔细看了下报错的原因，去把对应目录下得testdata删掉了。然后就成功了。

5、main方法上添加注解

6、添加路由
