go get github.com/beego/bee

需要配置环境变量或者临时设置 set PATH=%PATH%;%GOPATH%/bin

new 命令 web应用

api 命令 api应用

bee new testApi

运行项目项目都依赖 go get github.com/astaxie/beegoopen in new window

bee run

app.conf 配置

appname = testweb
runmode = dev

[dev]
httpport = 8080
[prod]
httpport = 8080
[test]
httpport = 8080

路由配置 router.go

 beego.Router("/beego", &controllers.MainController{})
 //任何方法访问
beego.Router("/beego", &controllers.MainController{},"*:Index")
beego.Router("/beego", &controllers.MainController{},"post:Index")
beego.Router("/beego", &controllers.MainController{},"put:Index")
beego.Router("/beego", &controllers.MainController{},"delete:Index")   
beego.Router("/beego", &controllers.MainController{},"get,post:Index")
beego.Router("/testinput",&controllers.TestinputController{},"get:Get;post:Post")


//测试controller
func (c *MainController)Post()  {
    c.Ctx.WriteString("this is method post!")
}

controller

继承controller

type MainController struct {
        beego.Controller
}


//TestController  t 必须大写
type TestController struct {
    beego.Controller
}

func (c *TestController) Get() {
    c.Data["Website"] = "beego.me" //data数据直接到tpl中
    c.Data["Email"] = "astaxie@gmail.com"
    c.TplName = "index.tpl" //模板名称
}

func (c *TestController)Post()  {
//相当于echo 
    c.Ctx.WriteString("<font style =\"color:red\">welcome</font>")
    //c.Ctx.WriteString("this is    method post!")
}

接收参数

//接收参数返回
 func (c *TestinputController) Get() {
    id :=c.GetString("id")
    c.Ctx.WriteString(id)
    id :=c.Input().Get("id")
    //fmt.Println(id)
    c.Ctx.WriteString(id)
}


//ParseForm 接收表单数据
type User struct {
    Id string
    Name string
}

func (c *TestinputController) Get() {

    u :=User{}
    if err :=c.ParseForm(&u); err !=nil{

    }
    c.Ctx.WriteString("   11 " +  u.Id  + "  111  "+u.Name)
}

使用RequestBody 接收数据

修改app.conf 
copyrequestbody = true


func (c *TestinputController) Get() {
    var ob models.Object
    json.Unmarshal(c.Ctx.Input.RequestBody,&ob)
    objectid := models.AddOne(ob)
    c.Data["json"]="{\"ObjectId\" :\"\"\" "+ objectid +"\"}"
    c.ServeJSON()
}

cookie

func (c *TestinputController) Get() {
    name := c.Ctx.GetCookie("name")
    password := c.Ctx.GetCookie("password")
    if name !=""{
        c.Ctx.WriteString("username:"+ name +"password:" +password)
    }else{
        c.Ctx.WriteString(`<html><form></form></html>`)
    }
}


func (c *TestinputController) Post() {
u :=User{}
if err:=c.ParseForm(&u) ; err != nil{

}
c.Ctx.SetCookie("name",u.Username , 100,"/")
c.Ctx.SetCookie("password", u.Password , 100 , "/")  //清楚cookie -1
c.Ctx.WriteString("Username:"+ u.Username + "password:" + u.Password)
}

session

//main设置
beego.BConfig.WebConfig.Session.SessionOn=true
//app.conf

sessionon = true


func (c *TestinputController) Get() {
    name := c.GetSession("name")
    if nameString , ok := name.(string); ok && nameString !=""{

    }

}

model

go get github.com/astaxie/beego/orm
go get github.com/go-sql-driver/mysql


type User struct {
    Id int
    Username string
    Password string
}
func (c *TestinputController) Get() {
    orm.RegisterDataBase("default","mysql","root:root@tcp(127.0.0.1:3306)/golang?charset=utf8" ,30)
    orm.RegisterModel(new(User))
    o:=orm.NewOrm()
    user :=User{
        Username:"zhangsan",
        Password:"123456",
    }
    //插入
    id,err :=o.Insert(&user)
    c.Ctx.WriteString(fmt.Sprint("%d   %v " , id , err))
}

type User struct {
    Id int
    Username string
    Password string
}
func (c *TestinputController) Get() {
    orm.RegisterDataBase("default","mysql","root:root@tcp(127.0.0.1:3306)/golang?charset=utf8" ,30)
    orm.RegisterModel(new(User))
    o:=orm.NewOrm()
    user :=User{
        Username:"zhangsan",
        Password:"222",
    }
    user.Id=1
    //修改
    id,err :=o.Update(&user)
    c.Ctx.WriteString(fmt.Sprint("%d   %v " , id , err))
}


var maps []orm.Params
num,err := o.Raw("Select * from user").Values(&maps)
for _,term :=range maps{
    fmt.Println((term["Id"]),":" , term["name"])
}

queryBuilder

    "fmt"
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql"
_ "github.com/lib/pq"
_ "github.com/mattn/go-sqlite3"


func (c *TestinputController) Get() {
    orm.Debug=true
    orm.RegisterDataBase("default","mysql","root:root@tcp(127.0.0.1:3306)/golang?charset=utf8" ,30)
    orm.RegisterModel(new(User2))
    o:=orm.NewOrm()
    var users []User2
    qb , _:=orm.NewQueryBuilder("mysql")
    qb.Select("Password").From("user").Where("Username = ?").Limit(1)
    sql:=qb.String()
    o.Raw(sql,"zhangsan").QueryRows(&users)
    c.Ctx.WriteString(fmt.Sprintf("user :%v" , users))
}

controller 调用 model

//models代码
package models

import (
    "github.com/astaxie/beego/orm"
    _ "github.com/go-sql-driver/mysql"
)

type User struct {
    Id int64
    Username string
    Password string
}

var(
    db orm.Ormer
)
func init()  {
    orm.Debug=true
    orm.RegisterDataBase("default","mysql","root:root@tcp(127.0.0.1:3306)/golang?charset=utf8" ,30)
    orm.RegisterModel(new(User))
    db = orm.NewOrm()

}
func AddUser(user_info * User)(int64,error)  {

  id,err := db.Insert(user_info)
  return id,err
}


//控制器代码
user := models.User{Username:"admin" , Password:"1235689"}
px,py := models.AddUser(&user)
fmt.Sprint(py)
c.Ctx.WriteString(strconv.FormatInt(px,10))//int64-> string

打包linux 的项目

bee pack -be GOOS=linux

orm

o := orm.NewOrm()
var user []orm.Params
num,err := o.Raw("select * from user limit 2").Values(&user)
fmt.Println(num)
fmt.Println(err)
for k,v:=range user{
    fmt.Println(k,v["user_id"] , v["user_name"])
}
return user

nginx 部署

Go 是一个独立的 HTTP 服务器，但是我们有些时候为了 nginx 可以帮我做很多工作，例如访问日志，cc 攻击，静态服务等，nginx 已经做的很成熟了，Go 只要专注于业务逻辑和功能就好，所以通过 nginx 配置代理就可以实现多应用同时部署，如下就是典型的两个应用共享 80 端口，通过不同的域名访问，反向代理到不同的应用。

server {
    listen       80;
    server_name  .a.com;

    charset utf-8;
    access_log  /home/a.com.access.log;

    location /(css|js|fonts|img)/ {
        access_log off;
        expires 1d;

        root "/path/to/app_a/static";
        try_files $uri @backend;
    }

    location / {
        try_files /_not_exists_ @backend;
    }

    location @backend {
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host            $http_host;

        proxy_pass http://127.0.0.1:8080;
