第四单元 参数配置

第四单元 参数配置

 

1.配置文件存放位置

conf/app.conf

xml:EXtensible Markup Language

html:

json:

xml和json的用途:用于数据交互与共享

xml json: json_encode,json_decode

 

appname:项目名称

runmode：运行级别，比如可设置为:dev,test,prod

httport:监听端口号

httpAddr:服务器地址

autorender:自动加载视图 默认为true,比如:true：自动加载，false：不自动加载

 

mysqluser = "root"

mysqlpass = "root"

mysqlurls = "127.0.0.1"

mysqldb = "beegotest"

redisurl = 127.0.0.1

redisport = 6379

 

2.获取配置参数

beego.AppConfig.String(参数名)

beego.AppConfig.String("runmode")

 

 

示例代码

appname = 1803a #项目名 runmode = test #运行模式 autorender = false #自动加载视图 [dev] httpport = 8088 #监听端口 dbhost = 127.0.0.1 dbport = 3306 dbuser = root dbpwd = root dbname = 1803a [test] httpport = 8080 #监听端口 dbhost = test.com dbport = 3306 dbuser = test dbpwd = test123456 dbname = 1803a

 

main.go获取

package main import ( _ "1803a/routers" "fmt" "github.com/astaxie/beego" ) func init() { runmode := beego.AppConfig.String("runmode") fmt.Printf("runmode:" + runmode) } func main() { beego.Run() }

 

多运行模式获取参数

用法:beego.AppConfig.String(运行模式::参数名)

例如:beego.AppConfig.String("test::httpport") 获取test模式下的httpport

 

多配置文件

include:引入子文件

 

app.conf

include "dev.conf"

include "test.conf"

 

dev.conf:

[dev]

httpport = 8088

dbhost = 127.0.0.1

dbport = 3306

dbuser = root

dbpwd = root

dbname = 1803a

 

 

test.conf

 

[test]

httpport = 8080

dbhost = test.com

dbport = 3306

dbuser = test

dbpwd = test123456

dbname = 1803a
