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) { o := orm.NewOrm() qs := o.QueryTable("t_user") var offset int64 if page > 1 { offset = (page - 1) * pageSize } if user.Id != 0 { qs = qs.Filter("id__exact", user.Id) } if user.Phone != "" { qs = qs.Filter("phone__contains", user.Phone) } if user.Name != "" { qs = qs.Filter("name__contains", user.Name) } 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.Name = u.Name user.Email = u.Email user.Phone = u.Phone user.Image = u.Image user.Addr = u.Addr tm2, _ := time.Parse("2006-02-02", u.Birth) //日期字符串转为时间戳
    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) } if len(u.Image) > 0 { user["Image"] = u.Image } if len(u.Remark) > 0 { user["Remark"] = u.Remark } if len(user) == 0 { return 0, errors.New("update field is empty") } var table User num, err := o.QueryTable(table).Filter("Id", u.Id).Update(user) return num, err } func GetUserByUsername(username string) (user User) { user = User{Name: username} o := orm.NewOrm() o.Read(&user, "Name") return user }

lib下的stringutil.go工具类:

package lib import ( "crypto/md5"
    "encoding/hex" ) //create md5 string
func Strtomd5(s string) string { h := md5.New() h.Write([]byte(s)) rs := hex.EncodeToString(h.Sum(nil)) return rs } //password hash function
func Pwdhash(str string) string { return Strtomd5(str) }
