Question

我有这种代码

systemctl restart openstack-nova-*
 systemctl restart openstack-nova-scheduler.service

结果不能给我带来任何进步。它只返回let req = Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers) req.downloadProgress { (progress) in print("progess!", Float(req.progress.fractionCompleted)) } req.responseJSON { response in if response.result.isSuccess { print(response.result.value!) } else { print(response.result.error!) } }，就这样，但是我需要此请求的进度。

请有人帮助我。

Answer 1

使用req.progress.fractionCompleted时出错。改用progress.fractionCompleted。

let req = Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
    req.downloadProgress { (progress) in
        print("progess!", Float(progress.fractionCompleted))
    }

    req.responseJSON { response in
        if response.result.isSuccess {
            print(response.result.value!)
        }
        else {
            print(response.result.error!)
        }
    }

在主队列中添加进度

request?.downloadProgress(queue: .main,closure: {progress in
        self.downloadProcess.text = "Download \((progress.fractionCompleted*100))% completed"
        print(self.downloadProcess.text)
        if #available(iOS 11.0, *) {

        } else {
            // Fallback on earlier versions
        }

    })
