golang学习之beego框架配合easyui实现增删改查及图片上传

demo目录：

upload文件夹主要放置上传的头像文件，main是主文件，所有效果如下：

删除：

新增/修改会员：

app.conf配置文件：

appname = easyui_crud
httpport = 8080
runmode = dev

#数据库配置
db.host = 192.168.20.132
db.port = 3306
db.user = root
db.pass = root
db.name = test
db.timezone = Asia/Shanghai

base.go主要放置一些公共操作：

package controllers

import (
    "github.com/astaxie/beego"
)

type BaseController struct {
    beego.Controller
}

func (this *BaseController) Rsp(status bool, str string) {
    this.Data["json"] = &map[string]interface{}{"succ": status, "msg": str}
    this.ServeJSON()
}

userController：

package controllers

import (
    m "easyui_crud/models"
    "fmt"
)

type UserController struct {
    BaseController
}

func (this *UserController) Index() {
    user := this.GetSession("userinfo")
    if user != nil {
        this.Data["userinfo"] = user
        this.TplName = "main.html"
        return
    }
    this.Redirect("/", 302)
}

func (this *UserController) UserIndex() {
    this.TplName = "user/usermanage.html"
}

func (this *UserController) UserList() {
    page, _ := this.GetInt64("page")
    pageSize, _ := this.GetInt64("rows")
    u := m.User{}
    if this.GetString("id") != "" {
        u.Id, _ = this.GetInt("id")
    }
    if this.GetString("name") != "" {
        u.Name = this.GetString("name")
    }
    if this.GetString("phone") != "" {
        u.Phone = this.GetString("phone")
    }
    nodes, cnt := m.GetUserList(page, pageSize, &u)
    this.Data["json"] = &map[string]interface{}{"total": cnt, "rows": &nodes}
    this.ServeJSON()
}

func (this *UserController) UserDel() {
    idstr := this.GetString("ids")
    err := m.DelUser(idstr)
    if err != nil {
        this.Rsp(false, err.Error())
    } else {
        this.Rsp(true, "删除成功")
    }
}

func (this *UserController) UserAdd() {
    u := m.User{}
    u.Id, _ = this.GetInt("Id")
    if err := this.ParseForm(&u); err != nil {
        this.Rsp(false, err.Error())
        return
    }
    id, err := m.AddUser(&u)
    if err == nil && id > 0 {
        this.Rsp(true, "新增成功")
        return
    } else {
        this.Rsp(false, err.Error())
        return
    }
}

func (this *UserController) UserUpdate() {
    u := m.User{}
    if err := this.ParseForm(&u); err != nil {
        this.Rsp(false, err.Error())
        return
    }
    id, err := m.UpdateUser(&u)
    if err == nil && id > 0 {
        this.Rsp(true, "修改成功")
        return
    } else {
        this.Rsp(false, err.Error())
        return
    }

}

func (this *UserController) UserUpload() {

    f, fh, err := this.GetFile("uploadFile")
    defer f.Close()
    if err != nil {
        fmt.Println("get file error ", err)
        this.Data["json"] = &map[string]interface{}{"path": "", "succ": false}
        this.ServeJSON()
    } else {
        fmt.Println(fh.Filename)
        this.SaveToFile("uploadFile", "static/upload/"+fh.Filename)
        this.Data["json"] = &map[string]interface{}{"path": "/static/upload/" + fh.Filename, "succ": true}
        this.ServeJSON()
    }

}

 

models下的init主要用来进行数据库初始化：

package models

import (
    "net/url"

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

func init() {
    dbhost := beego.AppConfig.String("db.host")
    dbport := beego.AppConfig.String("db.port")
    dbname := beego.AppConfig.String("db.name")
    dbuser := beego.AppConfig.String("db.user")
    dbpass := beego.AppConfig.String("db.pass")
    timezone := beego.AppConfig.String("db.timezone")

    if dbport == "" {
        dbport = "3306"
    }
    dsn := dbuser + ":" + dbpass + "@tcp(" + dbhost + ":" + dbport + ")/" + dbname + "?charset=utf8"
    if timezone != "" {
        dsn = dsn + "&loc=" + url.QueryEscape(timezone)
    }
    orm.RegisterDataBase("default", "mysql", dsn, 5, 30)
    if beego.AppConfig.String("runmode") == "dev" {
        orm.Debug = true
    }
}

user models，user类的增删改查具体实现封装：

package models

import (
    "errors"
    "fmt"
    "log"
    "strconv"
    "strings"
    "time"

    "github.com/astaxie/beego/orm"
    "github.com/astaxie/beego/validation"
)

type User struct {
    Id      int
    Name    string `form:"name" valid:"Required;MaxSize(20);MinSize(6)"`
    Pass    string `form:"pass" valid:"Required;MaxSize(20);MinSize(6)"`
    Email   string `form:"email" valid:"Required;Email"`
    Phone   string `form:"phone" valid:"Required;Mobile"`
    Image   string `form:"image" valid:"MaxSize(50);MinSize(6)"`
    Addr    string `form:"addr" valid:"MaxSize(30)" form:"name"`
    Regtime string
    Birth   string `form:"birth"`
    Remark  string `valid:"MaxSize(200)" form:"remark"`
}

func init() {
    orm.RegisterModel(new(User))
}

func (u *User) TableName() string {
    return "t_user"
}

func (this *User) ToString() string {
    return fmt.Sprintf("Id:%d\tName:%s", this.Id, this.Name)
}

func checkUser(u *User) (err error) {
    valid := validation.Validation{}
    b, _ := valid.Valid(&u)
    if !b {
        for _, err := range valid.Errors {
            log.Println(err.Key, err.Message)
            return errors.New(err.Message)
        }
    }
    return nil
}

func GetUserList(page int64, pageSize int64, user *User) (userlist []*User, count int64) {

    var offset int64

    qs.Limit(pageSize, offset).OrderBy("-Id").All(&userlist)
    count, _ = qs.Count()
    return userlist, count
}

func DelUser(idstr string) error {
    ids := strings.Split(idstr, ",")
    num, err := orm.NewOrm().QueryTable("t_user").Filter("id__in", ids).Delete()
    if num > 0 && err == nil {
        return nil
    } else {
        return err
    }
}

func AddUser(u *User) (int64, error) {
    if err := checkUser(u); err != nil {
        return 0, err
    }
    o := orm.NewOrm()
    user := new(User)

    user.Birth = strconv.FormatInt(tm2.Unix(), 10)

    user.Remark = u.Remark
    user.Regtime = strconv.FormatInt(time.Now().Unix(), 10) //获取当前时间戳
    id, err := o.Insert(user)
    return id, err
}

func UpdateUser(u *User) (int64, error) {
    if err := checkUser(u); err != nil {
        return 0, err
    }
    o := orm.NewOrm()
    user := make(orm.Params)
    if len(u.Name) > 0 {
        user["Name"] = u.Name
    }
    if len(u.Phone) > 0 {
        user["Phone"] = u.Phone
    }
    if len(u.Addr) > 0 {
        user["Addr"] = u.Addr
    }
    if len(u.Email) > 0 {
        user["Email"] = u.Email
    }
    if len(u.Birth) > 0 {
        tm, _ := time.Parse("2006-02-02", u.Birth) //日期字符串转为时间戳
        user["Birth"] = strconv.FormatInt(tm.Unix(), 10)

func GetUserByUsername(username string) (user User) {
    user = User{Name: username}
    o := orm.NewOrm()
    o.Read(&user, "Name")
    return user
