我无法为我的结构获取正确的定义来捕获json保存在变量中的嵌套数据。我的代码片段如下:
package main
import "fmt"
import "encoding/json"
type Data struct {
P string `json:"ports"`
Ports struct {
Portnums []int
}
Protocols []string `json:"protocols"`
}
func main() {
y := `{
"ports": {
"udp": [
1,
30
],
"tcp": [
100,
1023
]
},
"protocols": [
"tcp",
"udp"
]
}`
var data Data
e := json.Unmarshal([]byte(y), &data)
if e == nil {
fmt.Println(data)
} else {
fmt.Println("Failed:", e)
}
}
$ go run foo.go
Failed: json: cannot unmarshal object into Go value of type string
