Go语言对JSON进行编码和解码

package mainimport (
    "fmt"
    "encoding/json")func main() {
    // json encode
    j1 := make(map[string]interface{})
    j1["name"] = "outofmemory"
    j1["url"] = "http://outofmemory.cn/"

    js1, err := json.Marshal(j1)
    if err != nil {
        panic(err)
    }

    println(string(js1))

    // json decode
    j2 := make(map[string]interface{})
    err = json.Unmarshal(js1, &j2)
    if err != nil {
        panic(err)
    }

    fmt.Printf("%#v\n", j2)}
