ios - 如何检查 Alamofire 因网络连接不良而失败？

Question

如何检查我的 Alamofire 请求是否因互联网连接不良而失败？我收到错误，但我怎么知道它因此而失败

Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo={_kCFStreamErrorCodeKey=-4, NSUnderlyingError=0x6000007fe6a0 {Error Domain=kCFErrorDomainCFNetwork Code=-1005 "(null)" UserInfo={NSErrorPeerAddressKey={length = 28, capacity = 28, bytes = 0x1c1e1f96000000000000000000000000 ... 0000000100000000}, _kCFStreamErrorCodeKey=-4, _kCFStreamErrorDomainKey=4}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalUploadTask .<1>, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalUploadTask .<1>" )

您可以从失败案例中获取错误消息，如下所示

Alamofire.request("YourURL", method: .post, parameters: parameters)
    .responseJSON { response in
    if case .failure(let error) = response.result {
        print(error.localizedDescription)//The network connection was lost.
    } else if case .success = response.result {
        print(response.result.value)
    }
}
