如何在 alamofire 中检查互联网连接? [英] How to check internet connection in alamofire?

问题描述

我正在使用以下代码在服务器中发出 HTTP 请求.现在我想知道它是否已连接到互联网.下面是我的代码

I am using below code for making HTTP request in server.Now I want to know whether it is connected to internet or not. Below is my code

  let request = Alamofire.request(completeURL(domainName: path), method: method, parameters: parameters, encoding: encoding.value, headers: headers)
      .responseJSON {


        let resstr = NSString(data: $0.data!, encoding: String.Encoding.utf8.rawValue)
        print("error is (resstr)")


        if $0.result.isFailure {
          self.failure("Network")
          print("API FAILED 4")
          return
        }
        guard let result = $0.result.value else {
          self.unKnownError()
          self.failure("")
          print("API FAILED 3")

          return
        }
        self.handleSuccess(JSON(result))
    }

推荐答案

对于 swift 3.1 和 Alamofire 4.4，我创建了一个名为 Connectivity 的 swift 类代码> .根据需要使用 Alamofire 中的 NetworkReachabilityManager 类和 configure isConnectedToInternet() 方法.

For swift 3.1 and Alamofire 4.4 ,I created a swift class called Connectivity . Use NetworkReachabilityManager class from Alamofire and configure the isConnectedToInternet() method as per your need.

import Foundation
import Alamofire

class Connectivity {
    class func isConnectedToInternet() -> Bool {
        return NetworkReachabilityManager()?.isReachable ?? false
    }
}

用法:

if Connectivity.isConnectedToInternet() {
        print("Yes! internet is available.")
        // do some tasks..
 }

由于 swift 鼓励计算属性，您可以更改上述函数，如:

Since swift is encouraging computed properties, you can change the above function like:

import Foundation
import Alamofire
class Connectivity {
    class var isConnectedToInternet:Bool {
        return NetworkReachabilityManager()?.isReachable ?? false
    }
}

并像这样使用它:

if Connectivity.isConnectedToInternet {
        print("Yes! internet is available.")
        // do some tasks..
 }
