Golang 巧用构造函数设置结构体的默认值

示例代码：

package main

import "fmt"

type s1 struct {
	ID string
	s2 s2
	s3 s3
}

type s2 struct {
	WebSiteName string
	URL         string
}

type s3 struct {
	KeyWord []string
	Where   string
}

func main() {

	ss := s1{
		ID: "123456",
		s2: s2{
			WebSiteName: "ydook.com",
			URL:         "www.ydook.com",
		},
		s3: s3{
			// 重点：在结构体内部使用数组
			KeyWord: []string{"IT", "AI", "Web", "technology", "knowledge"},
			Where:   "IT",
		},
	}

	fmt.Println(ss)
}

运行结果：

main.SomeStruct
{16881699 www.ydook.com}
