如何检查alamofire中的互联网连接？ [英] How to check internet connection in alamofire?

问题描述

我正在使用下面的代码在服务器中发出HTTP请求。现在我想知道它是否连接到互联网。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

适用于swift 3.1和Alamofire 4.4 ，我创建了一个名为 Connectivity 的快速类。使用 NetworkReachabilityManager 类 Alamofire 和配置 isConnectedToInternet（）方法根据您的需要。

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
    }
}

用法：

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

编辑：
由于swift鼓励计算属性，您可以更改以上函数如：

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
    }
}

并使用它：

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