只需指定Foos何時(shí)解組
package main
import "fmt"
import "encoding/json"
type Foo struct {
Id uint64 `json:"id"`
Name string `json:"name"`
}
type BaseResult struct {
Error string `json:"error"`
}
type FooResult struct {
BaseResult
Foos []Foo
}
func main() {
// Simple and works.
structBody := []byte(`{"id": 1,"name": "foo"}`)
structResult := Foo{}
json.Unmarshal(structBody, &structResult)
fmt.Printf("%#v\n", structResult)
// Doesn't work.
arrayBody := []byte(`[{"id": 1,"name": "foo"},{"id": 2,"name": "bar"},{"id": 3,"name": "foobar"}]`)
arrayResult := FooResult{}
if err := json.Unmarshal(arrayBody, &arrayResult.Foos); err != nil {
arrayResult.BaseResult.Error = string(arrayBody)
}
fmt.Printf("%#v\n", arrayResult)
}
