下载安装GoLand

goland 会自动安装golang，但是不会设置全局环境变量。需要手动设置，在goland中找到sdk地址。

安装beego

# 设置网络环境
go env -w GOPROXY=https://goproxy.io,direct
go env -w GO111MODULE=on

# 安装bee
go get -u github.com/astaxie/beego
go get -u github.com/beego/bee

# 检查bee 
bee version

# bee如果失败，需要手动打包bee
# 查看环境变量
go env  
GOPATH=C:\Users\Administrator\go
# 找到bee地址
C:\Users\Administrator\go\src\github.com\beego\bee
# 三种任意一种都行，都试一下吧，不太确定是哪个。我记得是前两个，第三个是我网上看见的。不一定生成bee.exe,也有可能是main.exe,名字改一下bee.exe,配置一下环境变量就好了，
go build 
go build main.go
go install

新建api

# 最开始我是这样的，发现不对
bee new bee-api
# 正确命令
bee api bee-api
# 需要修改swagger/index.html, 
#SwaggerUIBundle url值:https://petstore.swagger.io/v2/swagger.json》swagger.json,不然不会显示正确的文档
# 访问：http://localhost:8080/swagger
# 程序配置信息修改在conf/app.conf文件

运行项目

bee run -gendoc=true -downdoc=true

orm可能需要获取

go get github.com/astaxie/beego/orm
