将地图转换为结构

最简单的方法是使用https://github.com/mitchellh/mapstructure

import "github.com/mitchellh/mapstructure"mapstructure.Depre(myData, &result)

如果您想自己做，则可以执行以下 *** 作：

func SetField(obj interface{}, name string, value interface{}) error {    structValue := reflect.ValueOf(obj).Elem()    structFieldValue := structValue.FieldByName(name)    if !structFieldValue.IsValid() {        return fmt.Errorf("No such field: %s in obj", name)    }    if !structFieldValue.CanSet() {        return fmt.Errorf("Cannot set %s field value", name)    }    structFieldType := structFieldValue.Type()    val := reflect.ValueOf(value)    if structFieldType != val.Type() {        return errors.New("Provided value type didn't match obj field type")    }    structFieldValue.Set(val)    return nil}type MyStruct struct {    Name string    Age  int64}func (s *MyStruct) FillStruct(m map[string]interface{}) error {    for k, v := range m {        err := SetField(s, k, v)        if err != nil { return err        }    }    return nil}func main() {    mydata:= make(map[string]interface{})    myData["Name"] = "Tony"    myData["Age"] = int64(23)    result := &MyStruct{}    err := result.FillStruct(myData)    if err != nil {        fmt.Println(err)    }    fmt.Println(result)}
