GoFrame框架Scan类型转换实例_Golang_

// Scan automatically calls MapToMap, MapToMaps, Struct or Structs function according to // the type of parameter `pointer` to implement the converting. // It calls function MapToMap if `pointer` is type of *map to do the converting. // It calls function MapToMaps if `pointer` is type of *[]map/*[]*map to do the converting. // It calls function Struct if `pointer` is type of *struct/**struct to do the converting. // It calls function Structs if `pointer` is type of *[]struct/*[]*struct to do the converting. func Scan(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)
