解决方案
extension WKWebView {
private var httpCookieStore: WKHTTPCookieStore { return WKWebsiteDataStore.default().httpCookieStore }
func getCookies(for domain: String? = nil, completion: @escaping ([String : Any])->()) {
var cookieDict = [String : AnyObject]()
httpCookieStore.getAllCookies { cookies in
for cookie in cookies {
if let domain = domain {
if cookie.domain.contains(domain) {
cookieDict[cookie.name] = cookie.properties as AnyObject?
}
} else {
cookieDict[cookie.name] = cookie.properties as AnyObject?
}
}
completion(cookieDict)
}
}
}
使用方法
// get cookies for domain
webView.getCookies(for: url.host) { data in
print("=========================================")
print("\(url.absoluteString)")
print(data)
}
// get all cookies
webView.getCookies() { data in
print("=========================================")
print("\(url.absoluteString)")
print(data)
}

代码
- 不要忘记在此处添加解决方案代码
- ViewController 包含嵌入的视图控制器
import UIKit
import WebKit
class ViewController: UIViewController {
private lazy var url = URL(string: "https://google.com")!
private weak var webView: WKWebView?
func initWebView(configuration: WKWebViewConfiguration) {
if webView != nil { return }
let webView = WKWebView(frame: UIScreen.main.bounds, configuration: configuration)
webView.navigationDelegate = self
webView.uiDelegate = self
view.addSubview(webView)
self.webView = webView
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if webView == nil { initWebView(configuration: WKWebViewConfiguration()) }
webView?.load(url: url)
}
}
extension ViewController: WKNavigationDelegate {
func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
decisionHandler(.allow)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
if let url = webView.url {
webView.getCookies(for: url.host) { data in
print("=========================================")
print("\(url.absoluteString)")
print(data)
}
}
}
}
extension ViewController: WKUIDelegate {
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if let url = navigationAction.request.url, navigationAction.targetFrame == nil {
let viewController = ViewController()
viewController.initWebView(configuration: configuration)
viewController.url = url
DispatchQueue.main.async { [weak self] in
self?.navigationController?.pushViewController(viewController, animated: true)
}
return viewController.webView
}
return nil
}
}
extension WKWebView {
func load(urlString: String) {
if let url = URL(string: urlString) { load(url: url) }
}
func load(url: URL) { load(URLRequest(url: url)) }
}
