Swift：如何使用HTTPS代理

我有一个付费代理（HTTP/HTTPS/SOCKS）。 我可以使用HTTP方案发出请求，但不能使用HTTPS

我总是犯错误：

Error Domain=kCFErrorDomainCFNetwork Code=311 "(null)" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <69F444DF-8C0E-4F4B-B723-C7BCD72B6C02>.<1>, _kCFStreamErrorDomainKey=4, _NSURLErrorRelatedURLSessionTaskErrorKey=(
    "LocalDataTask <69F444DF-8C0E-4F4B-B723-C7BCD72B6C02>.<1>"
), _kCFStreamErrorCodeKey=-2097}

请求功能：

private func getProxySessionConfigration() -> URLSessionConfiguration {
        
        let login = ConfigurationData.proxy.login
        let password = ConfigurationData.proxy.password
        let sessionConfiguration = URLSessionConfiguration.default
        
        let userPasswordString = "\(login):\(password)"
        let userPasswordData = userPasswordString.data(using: String.Encoding.utf8)
        let base64EncodedCredential = userPasswordData!.base64EncodedString(options: Data.Base64EncodingOptions(rawValue: 0))
        let authString = "Basic \(base64EncodedCredential)"
        sessionConfiguration.httpAdditionalHeaders = ["Authorization" : authString]
        
        
        sessionConfiguration.connectionProxyDictionary = [
            "HTTPEnable": true,
            "HTTPPort": ConfigurationData.proxy.port,
            "HTTPProxy": ConfigurationData.proxy.host,
            "HTTPSEnable": true,
            "HTTPSPort": ConfigurationData.proxy.port,
            "HTTPSProxy": ConfigurationData.proxy.host
        ]
        
        return sessionConfiguration
    }

public func getPage(_ url: URL, completion: @escaping (String?, RequestError?) -> Void) {
        
        let session = URLSession(configuration: getProxySessionConfigration())
        let task = session.dataTask(with: url) { (data, response, error) in
            
            guard let httpResponse = response as? HTTPURLResponse,
                  (200...299).contains(httpResponse.statusCode) else {
                if let error = error {
                    completion(nil, .requestFailed(error))
                } else {
                    completion(nil, .unknown(response))
                }
                return
            }
            
            
            if let data = data {
                print(httpResponse)
                if let urlContent = NSString(data: data, encoding: String.Encoding.utf8.self.rawValue) {
                    completion(urlContent as String, nil)
                } else {
                    completion(nil, .dataDecodeFailed(data))
                }
            } else {
                completion(nil, .noData)
            }
            
        }
        
        task.resume()
   
    }

let requestAvito = AvitoProjectPlaygroud_Sources.RequestAvito()

 let url = URL(string: "https://www.avito.ru/krasnodar/vakansii/voditel_v_yandeks_taksi_zarabotok_ot_1388074044")!


requestAvito.getPage(url) { (htmlString, error) in
    if let error = error {
        switch error {
            case .noData: print("ERROR: no data")
            case .unknown(let response):
                print("ERROR: unknown error")
                if let response =  response { print(response) }
            case .urlFailed: print("ERROR: url generating failed")
            case .requestFailed(let returnedError): print("ERROR: \(returnedError)")
            case .dataDecodeFailed(let data):
                print("ERROR: data decoding failed")
                print(data!)
        }
        return
    }
    
    if let htmlString = htmlString {
        // print(htmlString)
        print(String(htmlEncodedString: htmlString))
    } else {
        print("NO DATA")
    }
}

函数调用：

        let login = ConfigurationData.proxy.login
        let password = ConfigurationData.proxy.password

        let userPasswordString = "\(login):\(password)"

        let base64EncodedCredential = userPasswordData!.base64EncodedString(options: Data.Base64EncodingOptions(rawValue: 0))
        let authString = "Basic \(base64EncodedCredential)"
        sessionConfiguration.httpAdditionalHeaders = ["Authorization" : authString]
        
        
        sessionConfiguration.connectionProxyDictionary = [

        ]
        
        return sessionConfiguration
    }

对于您的问题，首先（在做其他事情之前，请确保您的代理处理HTTPS代理），如果否，则不管您输入的代码如何

要处理HTTPS代理，有两个键可以使用，似乎您正在使用它。我可以看到的一件事是，您使用true作为布尔值，等等

根据我的经验，我总是使用数值或字符串

确保数据以字符串/Int（true->1）等形式传递，这可能会有所帮助

有时，它会对那些将“真”转换为1的假设产生一些问题

下面是我如何使用它的示例：

  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] = "xxx.yyy.zzz.bbb"
    config.connectionProxyDictionary?[kCFNetworkProxiesHTTPPort as String] = 8888
    config.connectionProxyDictionary?[kCFStreamPropertyHTTPSProxyHost as String] = "xxx.yyy.zzz.bbb"
    config.connectionProxyDictionary?[kCFStreamPropertyHTTPSProxyPort as String] = 8888

简言之：

• 首先验证您的代理（确保已处理https代理）
• 然后按上述方式传递数据

希望它能解决您的问题。

谢谢您的回答。我检查了你的代码，得到了同样的问题-error（（一个也检查了代理（使用命令行））并且它可以同时工作两种类型-HTTPS和HTTPS
