Our application allows logging in via SSO, which we do by firing up a WKWebKit view to a particular URL that communicates to our server, and eventually redirects to a URL that we are expecting. During this process we get a cookie that we need to transfer to our SessionManager, however, when trying to get the cookies from the WKHTTPCookieStore, we don't always get the callback. Here is some code:
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
let httpCookieStore = WKWebsiteDataStore.default().httpCookieStore
httpCookieStore.getAllCookies { (cookies) in
// This block not always called!!!
}
}
This typically happens on initial install of the app on device, and is reproducible almost always on device, but not in the simulator.
At this point I have tried everything I can think of, but I don't know why the callback is sometimes called but not always.
To see all cookies you can use this code
import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate {
var webView: WKWebView?
override func viewDidLoad() {
super.viewDidLoad()
let configuration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero,configuration:configuration)
self.view = webView
}
override func viewDidAppear(_ animated: Bool) {
let url = URL(string: "YOUR URL")
let request = URLRequest(url: url!)
webView?.navigationDelegate = self
webView?.addObserver(self, forKeyPath: "URL", options: [.new, .old], context: nil)
self.webView?.load(request)
}
override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
if let newValue = change?[.newKey] as? Int, let oldValue = change?[.oldKey] as? Int, newValue != oldValue {
print("NEW",change?[.newKey])
} else {
print("OLD",change?[.oldKey])
}
webView?.configuration.websiteDataStore.httpCookieStore.getAllCookies { cookies in
for cookie in cookies {
print(cookie)
}
}
}
}
