Wkwebview 100％丢包预设

2024-05-03 • 问答

我有一个异步调用，用于在新的wkwebview中刷新我的cookie。

 public override func viewDidLoad() {
            super.viewDidLoad()
            let cookies = cookieService.getcookies(forDomain: urlService.getTopLevelDomain())
            authenticationService.authenticateIfNeeded { [weak self] error in
                if let error = error {
                   print(failed)
                } else {

                self?.identityService.storeCookies(cookies) {
                    DispatchQueue.main.async {
                        self?.loadRequest()
                    }
                }
            }
        }

public func authenticateIfNeeded(completion: @escaping (Error?) -> Void) {
       let domain = urlService.getTopLevelDomain()
        identityService.refreshCookies(for: domain,force: true,completion: completion)
    }

我已将网络设置为100％丢包预设。

在身份服务中具有setcookies的逻辑具有重试选项，完成此重试调用总共需要60秒。

func storeCookies(_ cookies: [AnyObject],completion: (() -> Void)? = nil) {

        let group = DispatchGroup()
        let httpCookies = cookies.compactMap { $0 as? HTTPCookie }
        for httpCookie in httpCookies {

            self.cookieStorageService.setCookie(httpCookie)
            group.enter()
            wkCookieStorage.setCookie(httpCookie) {
                group.leave()
            }
        }
        group.notify(queue: .main) {
            completion?()
        }
    }



func refreshCookies(for domain: String,force: Bool,completion: @escaping VoidResultHandler) {
        Retry<Void>.call(
            shouldRetry: self.shouldRetryIdentityOperation,handler: completion,method: { completion in
                self.identityOperations.refreshCookies(force: force,domain: domain,handler: { result in
                    switch result {
                    case .value(let cookies):
                        self.storeCookies(cookies) {
                            completion(.value(()))
                        }
                    case .error(let error):
                        completion(.error(error))
                    }
                })
        })
    }

直到出现空白屏幕，然后出现重试选项。如何减少这种延迟以拥有更好的用户体验。

import UIKit import WebKit class ViewController: UIViewController { private weak var webView: WKWebView! public override func viewDidLoad() { super.viewDidLoad() let webView = WKWebView(frame: .zero,configuration: WKWebViewConfiguration()) view.addSubview(webView) webView.translatesAutoresizingMaskIntoConstraints = false webView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true webView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true view.rightAnchor.constraint(equalTo: webView.rightAnchor).isActive = true view.bottomAnchor.constraint(equalTo: webView.bottomAnchor).isActive = true self.webView = webView checkNetworkSpeed(timeout: 5) { [weak self] error in guard let self = self else { return } if let error = error { print("!!!!

HTTPURLResponse else { responseError = CheckNetworkErrors.noResponse return } guard (200...299).contains(httpResponse.statusCode) else { responseError = CheckNetworkErrors.wrongStatusCode(httpResponse.statusCode) return } }).resume() } } }
