Beego的使用

 

1.Beego概述

官网帮助文档连接

2.Beego的启动

启动Beego

import (
        _ "quickstart/routers"
        "github.com/beego/beego/v2/server/web"
)

func main() {
        web.Run()
}

添加控制器

package routers

import (
        "quickstart/controllers"
        "github.com/beego/beego/v2/server/web"
)

func init() {

   web.Router("/", &controllers.MainController{})
}

说明：
web.Router添加Uri相应的Controller对象
web.Run进行如下四个处理：
解析configuration file，即app.conf文件，其中监听端口的配置

2.1 配置文件

appname = beepkg
httpaddr = "127.0.0.1"
httpport = 9090
runmode ="dev"
autorender = false
recoverpanic = false
viewspath = "myview"

These configurations will replace Beego’s default values.

Other application specific values can also be set using this file, such as database connection details:

mysqluser = "root"
mysqlpass = "rootpass"
mysqlurls = "127.0.0.1"
mysqldb   = "beego"

These configurations can be accessed like this:

beego.AppConfig.String("mysqluser")
beego.AppConfig.String("mysqlpass")
beego.AppConfig.String("mysqlurls")
beego.AppConfig.String("mysqldb")

AppConfig’s methods:

• Set(key, val string) error
• String(key string) string
• Strings(key string) []string
• Int(key string) (int, error)
• Int64(key string) (int64, error)
• Bool(key string) (bool, error)
• Float(key string) (float64, error)
• DefaultString(key string, defaultVal string) string
• DefaultStrings(key string, defaultVal []string)
• DefaultInt(key string, defaultVal int) int
• DefaultInt64(key string, defaultVal int64) int64
• DefaultBool(key string, defaultVal bool) bool
• DefaultFloat(key string, defaultVal float64) float64
• DIY(key string) (interface{}, error)
• GetSection(section string) (map[string]string, error)
• SaveConfigFile(filename string) error

When using the INI format the key supports the section::key pattern.

The Default* methods can be used to return default values if the config file cannot be read.
