使用Kingfisher访问一些服务器证书不被信任的问题

在用Charles抓包过程中使用KingFisher时遇到如下问题
"The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxx.xxx.xx” which could put your confidential information at risk."

Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxx.xxx.xx” which could put your confidential information at risk." UserInfo={NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, NSErrorPeerCertificateChainKey=(

方案一、
首先在模拟器上安装charles的https证书，也就是
1、在模拟器的浏览器里输入：chls.pro/ssl，然后点击alow
2、之后到模拟器的设置里安装证书（iOS15 系统的入口：Setting-General-Device Management - 选则要安装的证书）
3、信任证书（iOS15 系统的入口：Setting-General-About-Certificate Trust Settings - 选则要信任的证书开启）

解放方案二：
处理特定的域名：

import Kingfisher
let downloader = KingfisherManager.shared.downloader
downloader.trustedHosts = Set(["xxx.xxx.xxx"])

方案三、
写一个类来处理

import Kingfisher

class TrustAllHostAuthenticationChanllengeTool: NSObject, AuthenticationChallengeResponsible {
    static let shared = TrustAllHostAuthenticationChanllengeTool()
    class func trustAllImageHost() {
        let downloader = KingfisherManager.shared.downloader
        downloader.authenticationChallengeResponder = TrustAllHostAuthenticationChanllengeTool.shared
    }
    public func downloader(
        _ downloader: ImageDownloader,
        didReceive challenge: URLAuthenticationChallenge,
        completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void)
    {
        let credential = URLCredential(trust: challenge.protectionSpace.serverTrust!)
        completionHandler(.useCredential, credential)
        return
    }

}

// 在appdelegate的finishlaunch里调用一下
class AppDelegate: UIResponder, UIApplicationDelegate {
   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        TrustAllHostAuthenticationChanllengeTool.trustAllImageHost()
        return true
    }
// other
}
