Json Marshal&＃xff1a;将数据编码成json字符串

package main
import("fmt""encoding/json"
)
type Stu struct {Name string &＃96;json:"name"&＃96;Age intHIgh boolsex stringClass *Class &＃96;json:"class"&＃96;
}type Class struct {Name stringGrade int
}func main() {//实例化一个数据结构&＃xff0c;用于生成json字符串stu :&＃61; Stu{Name: "张三",Age: 18,HIgh: true,sex: "男",}//指针变量cla :&＃61; new(Class)cla.Name &＃61; "1班"cla.Grade &＃61; 3stu.Class&＃61;cla//Marshal失败时err!&＃61;niljsonStu, err :&＃61; json.Marshal(stu)if err !&＃61; nil {fmt.Println("生成json字符串错误")}fmt.Println(string(jsonStu))var a &＃61; [3]Stu{stu, stu, stu}jsonStu2, err2 :&＃61; json.Marshal(a)if err2 !&＃61; nil {fmt.Println("生成json字符串错误")}//jsonStu是[]byte类型&＃xff0c;转化成string类型便于查看fmt.Println(string(jsonStu2))
