1、通过map生成json
示例1：
package main
import (
"encoding/json"
"fmt"
)
func main() {
//创建一个map
m := make(map[string]interface{}, 4)
m["company"] = "itcast"
m["subjects"] = []string{"Go", "C++", "Python", "Test"}
m["isok"] = true
m["price"] = 666.666
//编码成json
result, err := json.Marshal(m)
if err != nil {
fmt.Println("err = ", err)
return
}
fmt.Println("result = ", string(result))
}
执行结果：
result = {"company":"itcast","isok":true,"price":666.666,"subjects":["Go","C++","Python","Test"]}
示例2：
package main
import (
"encoding/json"
"fmt"
)
func main() {
//创建一个map
m := make(map[string]interface{}, 4)
m["company"] = "itcast"
m["subjects"] = []string{"Go", "C++", "Python", "Test"}
m["isok"] = true
m["price"] = 666.666
//编码成json
result, err := json.MarshalIndent(m, "", " ")
if err != nil {
fmt.Println("err = ", err)
return
}
fmt.Println("result = ", string(result))
}
执行结果：
result = {
"company": "itcast",
"isok": true,
"price": 666.666,
"subjects": [
"Go",
"C++",
"Python",
"Test"
]
}
