问题内容
我正在尝试使用结构体的动态字段键来解组 json 该 json 从 linux 的 storcli 实用程序返回。 代码的一部分运行良好，但如果 json 数据包含许多结构，我无法对其进行解组。 我认为这是因为 drivedetailedinformation 结构没有所有 json 标签。 有人可以帮助我吗？

`
func main() {
var f jsonStruct
err := json.Unmarshal([]byte(jsonData), &f)
if err != nil {
fmt.Println("Error parsing JSON: ", err)
}
for _, controller := range f.Controllers {
for k, v := range controller.ResponseData {
///THAT IS WORK
var ds []DriveStruct
if err := json.Unmarshal(*v, &ds); err == nil {
fmt.Println(k, ds)
}
///THAT IS NOT WORK WHY?
var dds DriveDetailedInformation
if err := json.Unmarshal(*v, &dds); err == nil {
fmt.Println(k, dds)
}
}
}
}解决方案
因为你的键值不正确。下面是我修改的代码。
type DriveDetailedInformation struct {
DriveState DriveStateStruct `json:"Drive /c0/e31/s0 State"`
DriveDeviceAttributes DriveDeviceAttributesStruct `json:"Drive /c0/e31/s0 Device attributes"`
DrivePoliciesSettings DrivePoliciesSettingsStruct `json:"Drive /c0/e31/s0 Policies/Settings"`
InquiryData string `json:"Inquiry Data"`
}
type DriveDetailedInformation1 struct {
DriveState DriveStateStruct `json:"Drive /c0/e31/s1 State"`
DriveDeviceAttributes DriveDeviceAttributesStruct `json:"Drive /c0/e31/s1 Device attributes"`
DrivePoliciesSettings DrivePoliciesSettingsStruct `json:"Drive /c0/e31/s1 Policies/Settings"`
InquiryData string `json:"Inquiry Data"`
}
func main() {
var f jsonStruct
err := json.Unmarshal([]byte(jsonData), &f)
if err != nil {
fmt.Println("Error parsing JSON: ", err)
}
for _, controller := range f.Controllers {
for k, v := range controller.ResponseData {
switch k {
case "Drive /c0/e31/s0","Drive /c0/e31/s1":
var ds []DriveStruct
if err := json.Unmarshal(*v, &ds); err == nil {
fmt.Println(k, ds)
}
case "Drive /c0/e31/s1 - Detailed Information":
var dds1 DriveDetailedInformation1
if err := json.Unmarshal(*v, &dds1); err == nil {
fmt.Println(k, dds1)
}
case "Drive /c0/e31/s0 - Detailed Information":
var dds DriveDetailedInformation
if err := json.Unmarshal(*v, &dds); err == nil {
fmt.Println(k, dds)
}
}
}
}
}
我认为响应数据可以在结构中解析。
