JSON（JavaScript Object Notation，JavaScript对象表示法）是一种轻量级的数据交换格式，因简单、可读性强被广泛使用。
JSON编码即将Go数据类型转换为JSON字符串
map转json
package main
import (
"encoding/json"
"fmt"
)
func main() {
m:= map[string][]string{
"name":{"flower"},
"type":{"玫瑰","百合"},
}
// map 转json
if data,err:= json.Marshal(m);err==nil{
fmt.Printf("%s",data)
}
fmt.Println("")
if data,err:= json.MarshalIndent(m,""," ");err==nil{
fmt.Printf("%s",data)
}
}
输出：
{"name":["flower"],"type":["玫瑰","百合"]}
{
"name": [
"flower"
],
"type": [
"玫瑰",
"百合"
]
}
Deb
package main import ( "encoding/json" "fmt" ) // 通过结构体标签，改变json的key type User struct { name string `json:"_name"` age int `json:"_age"` sex uint `json:"-"` address string } func main() { user:=User{ name: "yo", age:20, sex:1, address: "polaris", } if data,err:= json.MarshalIndent(user,""," ");err==nil{ fmt.Printf("%s",data) } }
