如何将嵌套的json转换为打字稿中的接口

Question

我目前有一个json响应，如下所示：

FixedIp: {_IpAddress: "10.98.0.199", _Subnet: "255.255.254.0", _DefaultGateway: "10.98.0.1", _MTU: "1500", _HostName: "icmp-5b2607a"}
IsDhcpEnabled: {_Value: "false"}
StaticRoute: {_IsEnabled: "true", _TargetIpAddress: "10.98.0.0", _Subnet: "255.255.254.0", _Gateway: "255.255.254.1"}

我创建了一个打字稿界面，如下所示：

export interface MediaAdapter {
    IsDhcpEnabled: IsDhcpEnabled;
    FixedIp: FixedIP;
    StaticRoute: StaticRoute;
}



export interface FixedIP {
    _DefaultGateway: string;
    _MTU: string;
    _Subnet: string;
    _IpAddress: string;
}
 export interface IsDhcpEnabled {
    _Value: boolean;
}

export interface StaticRoute {
    _IsEnabled: boolean;
    _Subnet: string;
    _Gateway: string;
    _TargetIpAddress: string;
}

我的回应如下：

 const parsedJSON = JSON.parse(JSON.stringify(obj[key]));
          const value: MediaAdapter = <MediaAdapter>parsedJSON as MediaAdapter;

我不知何故把所有的布尔值都当作字符串。我的布尔值arent被解析为字符串。 我做错了什么？
