sessionConfig.httpMaximumConnectionsPerHost = 5
sessionConfig.httpShouldSetCookies = true
sessionConfig.httpCookieAcceptPolicy = .onlyFromMainDocumentDomain

// 设置是否允许使用不受信任的证书
sessionConfig.shouldAllowInvalidSSLCertificates = true

let session = URLSession(configuration: sessionConfig)

let url = URL(string: "https://www.example.com")!

let task = session.dataTask(with: url) { (data, response, error) in
    // 处理响应数据
    if let error = error {
        print("请求失败：\(error)")

        let responseString = String(data: data, encoding: .utf8)
        print("响应数据：\(responseString ?? "")")
    }
}

task.resume()
