1. Struct转Map

      1. func StructToMap(obj interface{}) map[string]interface{}{
      2.  obj1 := reflect.TypeOf(obj)
      3.  obj2 := reflect.ValueOf(obj)
      5.  var data = make(map[string]interface{})
      6.  for i := 0; i < obj1.NumField(); i++ {
      7.      data[obj1.Field(i).Name] = obj2.Field(i).Interface()
      8.  }
      9.  return data
      10. }

    2.Map转Struct

    1. func MapToStruct(){
    2.         mapInstance := make(map[string]interface{})
    3.         mapInstance["Name"] = "jqw"
    4.         mapInstance["Age"] = 18
    6.         var people People
    7.         err := mapstructure.Decode(mapInstance, &people)
    8.         if err != nil {
    9.                 fmt.Println(err)
    10.         }
    11.         fmt.Println(people)
    12. }

    3.map[string]string类型转换为map[string]interface{}

    1. var src []map[string]string
    2. var dest []map[string]interface{}
    4. for i := range src {
    5.     m := src[i]
    6.     n := make(map[string]interface{})
    7.     for k,v := range m {
    8.         n[k] = interface{}(v)
    9.     }
    10.     dest = append(dest, n)
    11. }
