Golang importing custom structures, implementing interfaces

Project root directory is Mygo, new go file, write an entry function

package mainfunc main() {    }

Create a new model folder and create a new. Go file (with no arbitrary file name), customize the structure

package peopletype Info struct {    Age int}type People struct {    Name string    Info Info}func (p People) Getname() string {    return p.Name}func (p People) Setname(name string) People {    p.Name = name    return p}

声明首字母大写可供外部调用

Create a new Imp folder to put the interface file, create a new. Go file, write an interface

package peopleiimport "mygo/model" //导入刚才的定义的结构体包type PeopleI interface {    Getname() string  // 返回类型string    Setname(name string) people.People  //放回类型为people}

Importing custom structures into the portal file and implementing interfaces

package mainimport (    "fmt"    "mygo/model" //结构体    "mygo/imp" //接口目录)func main() {    var pi peoplei.PeopleI = new(people.People); //声明接口    p := pi.Setname("dagx") //Setname返回结构体，此处声明p并赋值    p.Info.Age = 10;    fmt.Print(p.Getname(), ":", p.Info.Age)}

Summarize

• 1. Import Package Imports is a folder, not a file name, the name of the files and import and call Independent

• 2. The name of the package is called, regardless of the file name

• 3. The property method is capitalized first, otherwise it cannot be called
