我正在尝试使用结构的动态字段键解组json 该json从storcli实用程序针对Linux返回。 代码的一部分工作良好，但是如果json数据包含许多结构，则无法解组。 我认为这是因为DriveDetailedInformation结构没有所有的json标签。 有人可以帮我吗？

由于您的密钥值不正确，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Response Data可以解析为一个结构。
