}tag中设置验证规则
validate:定义验证规则
lable：自定义错误提示

控制层验
func (userAddressApi *UserAddressApi) CreateDealerUserAddress(c *gin.Context) {
userToken, _, e := common.GetContextDealerUser(c)
if e != nil {
response.FailWithMessage("获取用户信息失败", c)
return
}
var userAddressApi erp.UserAddress
err := c.ShouldBindJSON(&userAddressApi)
if err != nil {
global.GVA_LOG.Error("参数解析失败!", zap.Error(err))
response.FailWithMessage("参数解析失败", c)
return
}
if msg, errCode := validator.Validate(userAddressApi); errCode != 0 {
err := fmt.Errorf("参数验证失败!code:%d msg:%s", errCode, msg)
global.GVA_LOG.Error(err.Error(), zap.Error(err))
response.FailWithMessage(err.Error(), c)
return
}
if err := userAddressService.CreateUserAddress(&userAddressApi, userToken); err != nil {
global.GVA_LOG.Error("创建失败!", zap.Error(err))
response.FailWithMessage("创建失败", c)
} else {
response.OkWithDetailed(userAddressApi, "创建成功", c)
