Question

我极力尝试将自定义cookie添加到WKWebView实例（不使用Javascript或类似的解决方法）。

在iOS 11及更高版本中，Apple提供了执行此操作的API：WKWebView的{{1}}具有属性WKWebsiteDataStore。

这是我的（示例）代码：

httpCookieStore

此后，如果我使用import UIKit import WebKit class ViewController: UIViewController { var webView: WKWebView! override func viewDidLoad() { webView = WKWebView() view.addSubview(webView) super.viewDidLoad() } override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) let cookie = HTTPCookie(properties: [ HTTPCookiePropertyKey.domain : "google.com", HTTPCookiePropertyKey.path : "/", HTTPCookiePropertyKey.secure : true, HTTPCookiePropertyKey.name : "someCookieKey", HTTPCookiePropertyKey.value : "someCookieValue"])! let cookieStore = webView.configuration.websiteDataStore.httpCookieStore cookieStore.setCookie(cookie) { DispatchQueue.main.async { self.webView.load(URLRequest(url: URL(string: "https://google.com")!)) } } } override func viewWillLayoutSubviews() { super.viewWillLayoutSubviews() webView.frame = view.bounds } }，则会看到我的cookie在cookie列表中。

但是，当使用Safari的开发人员工具（当然使用iOS模拟器）检查Web视图时，cookie不会显示。

我还尝试使用HTTP代理（以我的情况为查尔斯）检查流量，以查看Cookie是否包含在我的HTTP请求中。不是。

我在这里做错了什么？如何将Cookie添加到webView.configuration.websiteDataStore.httpCookieStore.getAllCookies(completionHandler:)（在iOS 11及更高版本上）？

Answer 1

有点晚了，但是我想分享一个对我有用的解决方案，希望它也可以帮助在iOS 12上也面临同样问题的人。

这是我使用的简化工作流程：

实例化WKWebsiteDataStore对象
将自定义Cookie设置为其httpCookieStore
等待设置cookie
实例化WKWebView
加载请求

为此，我创建了WKWebViewConfiguration的扩展：

extension WKWebViewConfiguration {

static func includeCookie(cookie:HTTPCookie, preferences:WKPreferences, completion: @escaping (WKWebViewConfiguration?) -> Void) {
     let config = WKWebViewConfiguration()
     config.preferences = preferences

     let dataStore = WKWebsiteDataStore.nonPersistent()

     DispatchQueue.main.async {
        let waitGroup = DispatchGroup()

        waitGroup.enter()
        dataStore.httpCookieStore.setCookie(cookie) {
            waitGroup.leave()
        }

        waitGroup.notify(queue: DispatchQueue.main) {
            config.websiteDataStore = dataStore
            completion(config)
        }
    }
}

在我的示例中，我使用它的方式如下：

override func viewDidLoad() {
  self.AddWebView()
}

private func addWebView(){

    let preferences = WKPreferences()
    preferences.javaScriptEnabled = true
    preferences.javaScriptCanOpenWindowsAutomatically = true

    let cookie = HTTPCookie(properties: [
        .domain: COOKIE_DOMAIN,
        .path: "/",
        .name: COOKIE_NAME,
        .value: myCookieValue,
        .secure: "TRUE",
        .expires: NSDate(timeIntervalSinceNow: 3600)
        ])

     //Makes sure the cookie is set before instantiating the webview and initiating the request
     if let myCookie = cookie {
        WKWebViewConfiguration.includeCookie(cookie: myCookie, preferences: preferences, completion: {
           [weak self] config in
              if let `self` = self {
                 if let configuration = config {
                    self.webView = WKWebView(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width , height: self.view.frame.height), configuration: configuration)

                    self.view.addSubview(self.webView)
                    self.webView.load(self.customRequest)
                 }
              }
     }
}

Answer 2

对google.com的任何请求都会重定向到www.google.com。

您需要将www.添加到cookie的domain字段。如果域或路径与请求不匹配，则不会发送cookie。

您可以显式添加cookie。

let url = URL(string: "https://www.google.com")!
var request = URLRequest(url: url)
if let cookies = HTTPCookieStorage.shared.cookies(for: url) {
    request.allHTTPHeaderFields = HTTPCookie.requestHeaderFields(with: cookies)
}
self.webView.load(request)

Answer 3

对于iOS 11或更高版本，您真的不需要担心cookie，因为它非常简单。像这样创建您的cookie。不要使其安全 true

let newcookie = HTTPCookie(properties: [
        .domain: "domain",
        .path: "/",
        .name: "name",
        .value: "vale",
        .secure: "FALSE",
        .expires: NSDate(timeIntervalSinceNow: 31556926)
        ])!

self.webview.configuration.websiteDataStore.httpCookieStore.setCookie(newcookie, completionHandler: {
                        // completion load your url request here. Better to add cookie in Request as well. like this way
       request.addCookies()
//enable cookie through request
        request.httpShouldHandleCookies = true

//load request in your webview.


                    })

请求范围在Cookie值“;”

之后添加

extension URLRequest {

internal mutating func addCookies() {
    var cookiesStr: String = ""

        let mutableRequest = ((self as NSURLRequest).mutableCopy() as? NSMutableURLRequest)!
            cookiesStr += cookie.name + "=" + cookie.value + ";"                

            mutableRequest.setValue(cookiesStr, forHTTPHeaderField: "Cookie")
            self = mutableRequest as URLRequest

     }

}

我还可以看到您没有设置wkwebview的WKWebViewConfiguration。设置您的wkwebview的配置。还要实现 WKHTTPCookieStoreObserver 并实现功能。

    func cookiesDidChange(in cookieStore: WKHTTPCookieStore) {
    // Must implement otherwise wkwebview cookie not sync properly
    self.httpCookieStore.getAllCookies { (cookies) in
        cookies.forEach({ (cookie) in

        })
    }
}

希望如此，这会起作用。

无法设置WKWebView设置Cookie（iOS 11+）
