ios – 如何在Swift 3中使用代理服务器的URLSession

概述对于API请求,我尝试使用代理设置URLSession.为了测试目的,我使用公共代理和响应IP的API. func makeRequestViaUrlSessionProxy(_ url: String, completion: @escaping (_ result: String?) -> ()) { let request = URLRequest(url: URL(string: 对于API请求,我尝试使用代理设置URLSession.为了测试目的,我使用公共代理和响应IP的API.

func makeRequestViaUrlSessionProxy(_ url: String,completion: @escaPing (_ result: String?) -> ()) {    let request = URLRequest(url: URL(string: url)!)    let config = URLSessionConfiguration.default    config.requestCachePolicy = URLRequest.CachePolicy.reloadIgnoringLocalCacheData    config.connectionProxyDictionary = [AnyHashable: Any]()    config.connectionProxyDictionary?[kcfNetworkProxIEshttpEnable as String] = 1    config.connectionProxyDictionary?[kcfNetworkProxIEshttpProxy as String] = "142.54.173.19"    config.connectionProxyDictionary?[kcfNetworkProxIEshttpPort as String] = 8888    let session = URLSession.init(configuration: config,delegate: nil,delegateQueue: OperationQueue.current)    let task = session.dataTask(with: request) {        (data: Data?,response: URLResponse?,error: Error?) in        if error != nil {            NSLog("ClIEnt-sIDe error in request to \(url): \(error)")            completion(nil)            return        }        if data == nil {            NSLog("Data from request to \(url) is nil")            completion(nil)            return        }        let httpResponse = response as? httpURLResponse        if httpResponse?.statusCode != 200 {            NSLog("Server-sIDe error in request to \(url): \(httpResponse)")            completion(nil)            return        }        let enCodingname = response?.textEnCodingname != nil ? response?.textEnCodingname : "utf-8"        let enCoding = CFStringConvertEnCodingTonsstringencoding(CFStringConvertIANACharSetnameToEnCoding(enCodingname as CFString!))        let stringData = String(data: data!,enCoding: String.EnCoding(rawValue: UInt(enCoding)))        session.invalIDateAndCancel()        completion(stringData)    }    task.resume()}

调用者：

overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    makeRequestViaUrlSessionProxy("https://API.ipify.org?format=Json") { string in        print(string)    }}

看起来配置完全被忽略了,因为即使使用了代理IP,响应IP始终是实际的设备IP

任何帮助是非常感谢.

编辑：按照用户hasan83的建议,采取“httpS密钥”似乎不是一个选择.

解决方法 我认为工作(应该被弃用)的键是：

kcfStreamPropertyhttpSProxyHostkcfStreamPropertyhttpSProxyPort

你可以试试这个代码吗？

func makeRequestViaUrlSessionProxy(_ url: String,completion: @escaPing (_ result: String?) -> ()) {    let request = URLRequest(url: URL(string: url)!)    let config = URLSessionConfiguration.default    config.requestCachePolicy = URLRequest.CachePolicy.reloadIgnoringLocalCacheData    config.connectionProxyDictionary = [AnyHashable: Any]()    config.connectionProxyDictionary?[kcfNetworkProxIEshttpEnable as String] = 1    config.connectionProxyDictionary?[kcfNetworkProxIEshttpProxy as String] = "142.54.173.19"    config.connectionProxyDictionary?[kcfNetworkProxIEshttpPort as String] = 8888    config.connectionProxyDictionary?[kcfStreamPropertyhttpSProxyHost as String] = "142.54.173.19"    config.connectionProxyDictionary?[kcfStreamPropertyhttpSProxyPort as String] = 8888    let session = URLSession.init(configuration: config,enCoding: String.EnCoding(rawValue: UInt(enCoding)))        session.invalIDateAndCancel()        completion(stringData)    }    task.resume()}

还请确保您的代理服务器配置为处理https请求.

注意：它可能会为这些键提供不推荐的警告,但键仍然工作(请参阅https://forums.developer.apple.com/thread/19356#131446)
