我有以下格式的json
{
"status_code": 200,
"status_message": "OK",
"response": {
"Messages": [
"CODE_NOT_AVAILABLE"
],
"UnknownDevices": {
"": [
"6",
"7",
"8",
"9",
"10"
]
}
}
}
正如我们所看到的那样,我们缺少一个索引键,在unknownDevices之后,我试图用以下方式使用golan解组这个json
package main
import (
"encoding/json"
"fmt"
)
type pushWooshResponse struct {
Status int `json:"status_code"`
Status_msg string `json:"status_message"`
Response response
}
type response struct {
Message []string `json:"Messages"`
UnknownDevices devices
}
type devices struct {
Udevices []string `json:""`
}
func main() {
itemInfoR := `{"status_code":200,"status_message":"OK","response":{"Messages":["CODE_NOT_AVAILABLE"],"UnknownDevices":{"devices":["6","7","8","9","10"]}}}`
itemInfoBytes := []byte(itemInfoR)
var ItemInfo pushWooshResponse
er := json.Unmarshal(itemInfoBytes, &ItemInfo)
if er != nil {
fmt.Println("Error", er.Error())
} else {
fmt.Println(ItemInfo)
}
}
输出
{200 OK {[CODE_NOT_AVAILABLE] {[]}}}
除了最后一部分,一切都工作正常,我无法解决这个问题。你能帮我解决json的最后一部分。

可能还有其他选项,但每当您看到奇怪的JSON时,您都可以通过实施json.Unmarshaler
和/或json.Marshaler
来实施自己的自定义(联合)编组。
也许是这样的:
type devices struct {
Udevices []string
}
func (d *devices) UnmarshalJSON(b []byte) error {
var x map[string][]string
err := json.Unmarshal(b, &x)
if err == nil {
// perhaps check that only a single
// key exists in the map as well
d.Udevices = x[""]
}
return err
}
func (d devices) MarshalJSON() ([]byte, error) {
x := map[string][]string{"": d.Udevices}
return json.Marshal(x)
}
