如何使用Alamofire 4和Swift 3的代理服务器

Question

请不要标记为重复,我无法用现有的线程解决我的问题.

我正在尝试将我的代理用于需要指定IP的API请求.为了调试我的问题,我从Web服务请求IP.

这是我目前的代码:

import UIKit
import Alamofire

class ViewController: UIViewController {

    var requestManager = Alamofire.SessionManager.default

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(true)

        var proxyConfiguration = [NSObject: AnyObject]()
        proxyConfiguration[kCFNetworkProxiesHTTPProxy] = "http://xxx@eu-west-static-01.quotaguard.com" as AnyObject?
        proxyConfiguration[kCFNetworkProxiesHTTPPort] = "9293" as AnyObject?
        proxyConfiguration[kCFNetworkProxiesHTTPEnable] = 1 as AnyObject?

        let cfg = Alamofire.SessionManager.default.session.configuration
        cfg.connectionProxyDictionary = proxyConfiguration

        let ip = URL(string: "https://api.ipify.org?format=json")

        requestManager = Alamofire.SessionManager(configuration: cfg)
        requestManager.request(ip!).response { response in
            print("Request: \(response.request)")
            print("Response: \(response.response)")
            print("Error: \(response.error)")

            if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
                print("Data: \(utf8Text)")
            }
        }
    }
}

问题是:无论是否有响应的IP都是相同的proxyConfiguration.非常感谢任何帮助.

PS:使用的物理设备.

我认为工作(应该被弃用)键是:

kCFStreamPropertyHTTPSProxyHost
kCFStreamPropertyHTTPSProxyPort

你能试试这段代码吗？

import UIKit
import Alamofire

class ViewController: UIViewController {

    var requestManager = Alamofire.SessionManager.default

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(true)

         var proxyConfiguration = [NSObject: AnyObject]()
         proxyConfiguration[kCFNetworkProxiesHTTPProxy] = "eu-west-static-01.quotaguard.com" as AnyObject?
         proxyConfiguration[kCFNetworkProxiesHTTPPort] = "9293" as AnyObject?
         proxyConfiguration[kCFNetworkProxiesHTTPEnable] = 1 as AnyObject?
         proxyConfiguration[kCFStreamPropertyHTTPSProxyHost as String] = "eu-west-static-01.quotaguard.com"
         proxyConfiguration[kCFStreamPropertyHTTPSProxyPort as String] = 9293
         proxyConfiguration[kCFProxyUsernameKey as String] = xxx
         //proxyConfiguration[kCFProxyPasswordKey as String] = "pwd if any"
        let cfg = Alamofire.SessionManager.default.session.configuration
        cfg.connectionProxyDictionary = proxyConfiguration

        let ip = URL(string: "https://api.ipify.org?format=json")

        requestManager = Alamofire.SessionManager(configuration: cfg)
        requestManager.request(ip!).response { response in
            print("Request: \(response.request)")
            print("Response: \(response.response)")
            print("Error: \(response.error)")

            if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
                print("Data: \(utf8Text)")
            }
        }
    }
}

另外,请确保您的代理服务器配置为处理https请求.

注意:它可能会对deprecated这些密钥发出警告但密钥仍然有效(请参阅https://forums.developer.apple.com/thread/19356#131446)

注意:我在这里发布了相同的答案.在这里发布的内容与此处适用的相同.Alamofire正在使用它URLSessionConfiguration.

根据 Manishg 的回答，我使用以下内容来避免警告

let configuration = URLSessionConfiguration.default
configuration.httpAdditionalHeaders = SessionManager.defaultHTTPHeaders

var proxyConfiguration = [String: AnyObject]()
proxyConfiguration.updateValue(1 as AnyObject, forKey: "HTTPEnable")
proxyConfiguration.updateValue("eu-west-static-01.quotaguard.com" as AnyObject, forKey: "HTTPProxy")
proxyConfiguration.updateValue(9293 as AnyObject, forKey: "HTTPPort")
proxyConfiguration.updateValue(1 as AnyObject, forKey: "HTTPSEnable")
proxyConfiguration.updateValue("eu-west-static-01.quotaguard.com" as AnyObject, forKey: "HTTPSProxy")
proxyConfiguration.updateValue(9293 as AnyObject, forKey: "HTTPSPort")
configuration.connectionProxyDictionary = proxyConfiguration

sharedManager = Alamofire.SessionManager(configuration: configuration)

https 常量已被弃用，可以随时删除。通过使用字符串值，代码可能会中断但不会崩溃
