仅作简单逻辑处理以走通流程，无阅读难度，前端模板采用Xadmin2.0的login.html，直接贴代码：
数据表user结构：
控制器login.go：
package controllers
import (
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
"testbeego/models"
)
type LoginController struct {
beego.Controller
CommentController
}
func (c *LoginController) Login() {
c.TplName = "login.html"
}
func (c *LoginController) LoginCheck(){
ReturnData := make(map[string]interface{})
var user models.User
account := c.Input().Get("account")
password := c.Input().Get("password")
o := orm.NewOrm()
user.Account = account
err := o.Read(&user,"account")
if err == orm.ErrNoRows{
ReturnData["status"] = -1
ReturnData["message"] = "账号不存在"
}else if err != nil{
ReturnData["status"] = -3
ReturnData["message"] = "数据库查询错误:"+err.Error()
}else{
if password == user.Password{
ReturnData["status"] = 1
ReturnData["message"] = "登录成功"
c.SetSession("userId",user.Id)
} else{
ReturnData["status"] = -2
ReturnData["message"] = "密码错误"
}
}
c.Data["json"] = ReturnData
c.ServeJSON()
c.StopRun()
}
模型user.go：
package models
type User struct {
Id int `json:"id" orm:"column(id)"`
Account string `json:"account" orm:"column(account)"`
Password string `json:"password" orm:"column(password)"`
CreateTime int `json:"create_time" orm:"column(create_time)"`
UpdateTime int `json:"update_time" orm:"column(update_time)"`
Status int `json:"status" orm:"column(status)"`
}
前端页面login.html：

基类控制器base.go：
package controllers
import (
"github.com/astaxie/beego"
)
type BaseController struct {
beego.Controller
}
type JsonReturn struct {
Msg string `json:"msg"`
Code int `json:"code"`
Data interface{} `json:"data"`
}
func (c *BaseController) ApiJsonReturn(msg string,code int,data interface{}) {
var JsonReturn JsonReturn
JsonReturn.Msg = msg
JsonReturn.Code = code
JsonReturn.Data = data
c.Data["json"] = JsonReturn
c.ServeJSON()
c.StopRun()
}
func (c *BaseController) Prepare() {
controller,action := c.Controller.GetControllerAndAction()
userId := c.GetSession("userId")
if userId == nil{
c.Ctx.Redirect(302,"/login")
}
}
入口main.go：
package main
import (
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql"
"testbeego/models"
_ "testbeego/routers"
)
func main() {
registerModel()
sessionConfig()
ormConfig()
beego.Run()
}
func registerModel() {
orm.RegisterModel(new(models.User))
}
func sessionConfig() {
beego.BConfig.WebConfig.Session.SessionOn = true
beego.BConfig.WebConfig.Session.SessionGCMaxLifetime = 86400
}
func ormConfig() {
_ = orm.RegisterDriver("mysql", orm.DRMySQL)
_ = orm.RegisterDataBase("default", "mysql", "root:jx5333136@/testbeego?charset=utf8")
}
