前置：

代码层次还是由低到高：model层数据库操作->service层封装->路由层调用业务

Gin篇：gorm 使用 - -零 - 博客园 (cnblogs.com)

1）get方式获取参数context.Query("xxx")

golang gin 获取请求中的查询参数，并设置默认值 - golang - 大象笔记 (sunzhongwei.com)

2)post方式获取参数context.Request.FormValue("xxx")

作用基本同上：可以查询url后的？参数、href超链里？后参数

1.路由层

	//用户模块r.POST("/user/getUserList", service.GetUserList) //遇到指定请求，调用service层的函数r.POST("/user/createUser", service.CreateUser)//r.GET("/user/createUser", service.CreateUser)  //用于swagger UI测试r.POST("/user/deleteUser", service.DeleteUser)r.POST("/user/updateUser", service.UpdateUser)r.POST("/user/findUserByNameAndPwd", service.FindUserByNameAndPwd)r.POST("/user/find", service.FindByID)

2.service层，这里都是post方式

1）.用户增加

func CreateUser(c *gin.Context) {user := models.UserBasic{}//get请求专用c.Query查询请求URL ?后面的参数// user.Name = c.Query("name")// password := c.Query("password")// repassword := c.Query("repassword")//post请求用函数FormValue//设置属性值user.Name = c.Request.FormValue("name")password := c.Request.FormValue("password")repassword := c.Request.FormValue("Identity")fmt.Println(user.Name, "  >>>>>>>>>>>  ", password, repassword)salt := fmt.Sprintf("%06d", rand.Int31())data := models.FindUserByName(user.Name)if user.Name == "" || password == "" || repassword == "" {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "用户名或密码不能为空！","data":    user,})return}if data.Name != "" {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "用户名已注册！","data":    user,})return}if password != repassword {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "两次密码不一致！","data":    user,})return}//user.PassWord = passworduser.PassWord = utils.MakePassword(password, salt)user.Salt = saltfmt.Println(user.PassWord)user.LoginTime = time.Now()user.LoginOutTime = time.Now()user.HeartbeatTime = time.Now()models.CreateUser(user)c.JSON(200, gin.H{"code":    0, //  0成功   -1失败"message": "新增用户成功！","data":    user,})
}

2）.删除

func DeleteUser(c *gin.Context) {user := models.UserBasic{}id, _ := strconv.Atoi(c.Query("id"))fmt.Println(id)user.ID = uint(id)models.DeleteUser(user)c.JSON(200, gin.H{"code":    0, //  0成功   -1失败"message": "删除用户成功！","data":    user,})}

3）.修改

func UpdateUser(c *gin.Context) {user := models.UserBasic{}id, _ := strconv.Atoi(c.PostForm("id"))user.ID = uint(id)user.Name = c.PostForm("name")user.PassWord = c.PostForm("password")user.Phone = c.PostForm("phone")user.Avatar = c.PostForm("icon")user.Email = c.PostForm("email")fmt.Println("update :", user)_, err := govalidator.ValidateStruct(user)if err != nil {fmt.Println(err)c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "修改参数不匹配！","data":    user,})} else {models.UpdateUser(user)c.JSON(200, gin.H{"code":    0, //  0成功   -1失败"message": "修改用户成功！","data":    user,})}}

4）.查

func FindUserByNameAndPwd(c *gin.Context) {data := models.UserBasic{}//name := c.Query("name")//password := c.Query("password")name := c.Request.FormValue("name")password := c.Request.FormValue("password")fmt.Println(name, password)user := models.FindUserByName(name)if user.Name == "" {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "该用户不存在","data":    data,})return}flag := utils.ValidPassword(password, user.Salt, user.PassWord)if !flag {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "密码不正确","data":    data,})return}pwd := utils.MakePassword(password, user.Salt)data = models.FindUserByNameAndPwd(name, pwd)c.JSON(200, gin.H{"code":    0, //  0成功   -1失败"message": "登录成功","data":    data,})
}func FindUserByNameAndPwd(c *gin.Context) {data := models.UserBasic{}//name := c.Query("name")//password := c.Query("password")name := c.Request.FormValue("name")password := c.Request.FormValue("password")fmt.Println(name, password)user := models.FindUserByName(name)if user.Name == "" {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "该用户不存在","data":    data,})return}flag := utils.ValidPassword(password, user.Salt, user.PassWord)if !flag {c.JSON(200, gin.H{"code":    -1, //  0成功   -1失败"message": "密码不正确","data":    data,})return}pwd := utils.MakePassword(password, user.Salt)data = models.FindUserByNameAndPwd(name, pwd)c.JSON(200, gin.H{"code":    0, //  0成功   -1失败"message": "登录成功","data":    data,})
}
