如何从`MoyaError`获取错误statusCode？(How to get error statusCode from `MoyaError`?)

 我正在使用Moya ， Moya_ModelMapper和RxSwift来执行网络请求。 这是我的示例代码： 
 
let provider = RxMoyaProvider<MyEndpoint>()
let observable: Observable<RegistrationResponse> = provider.request(.register(firstName: "", lastName: "", email: "", password: "")).mapObject(type: RegistrationResponse.self)
observable.subscribe {
    [weak self] (event: Event<RegistrationResponse>) in
    switch event {
    case .next(let response):
        print(response)
    case .error(let error):
        print(error)
    case .completed:
        break
    }
}
 
 一切工作正常，但我不知道如何从服务器收到例如409状态码响应类型时得到错误代码。 如果我打印错误，我会得到： 
 
 jsonMapping(Status Code: 409, Data Length: 0) 
 
 但我不知道如何通过代码获取此状态码。 错误是MoyaError ，它是一个Enum类型。 这里是MoyaError的源代码 。 
 
 谢谢！ 

I'm using a Moya, Moya_ModelMapper and RxSwift to perform network requests. Here is my example code: 
 
let provider = RxMoyaProvider<MyEndpoint>()
let observable: Observable<RegistrationResponse> = provider.request(.register(firstName: "", lastName: "", email: "", password: "")).mapObject(type: RegistrationResponse.self)
observable.subscribe {
    [weak self] (event: Event<RegistrationResponse>) in
    switch event {
    case .next(let response):
        print(response)
    case .error(let error):
        print(error)
    case .completed:
        break
    }
}
 
Everything works fine, but I don't know how to get an error code when I receive for example a 409 status code response type from the server. If I print the error I will get: 
 
jsonMapping(Status Code: 409, Data Length: 0)
 
but I don't know how to get this status code by code. The error is MoyaError which is an Enum type. Here it's a source code of MoyaError.
 
Thanks!
