[GO]使用map生成 json

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    m := make(map[string]interface{}, 4) //因为结构体的键名都是字符串类型，但是值有很多类型，这里就使用interface{}万能类型，容量为4
    m["company"] = "zyg"
    m["subject"] = []string{"go", "python", "java"}
    m["isok"] = true
    m["price"] = 5.55

    result, err := json.Marshal(m)
    if err != nil {
        return
    }
    fmt.Println("result = ", string(result))
}

执行结果

result =  {"company":"zyg","isok":true,"price":5.55,"subject":["go","python","java"]}
