swift 3 clear version

Question

如果有一个主题，人们可以使用新语言Swift轻松了解如何在Webview中管理Cookie？如果您在互联网上办理登机手续，则在您需要实施此计划时，您将无法找到任何有趣的内容。甚至苹果的文档也很差。

有人知道如何在Swift中处理这些过程吗？这是我在Obj-C中找到的：

SEE COOKIES STORED

NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
NSLog(@"%@", cookie);
}

删除已存储的Cookie

NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in [storage cookies]) {
[storage deleteCookie:cookie];
}
[[NSUserDefaults standardUserDefaults] synchronize];

如果我们能给出一次这样的答案，对每个人都会很好！干杯！

Answer 1

试试这段代码：

SEE COOKIES STORED

    if let cookies = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies {
        for cookie in cookies {
            NSLog("\(cookie)")
        }
    }

删除已存储的Cookie

    var storage : NSHTTPCookieStorage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
    for cookie in storage.cookies  as! [NSHTTPCookie]{
        storage.deleteCookie(cookie)
    }

swift 2.0

let storage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
for cookie in storage.cookies! {
 storage.deleteCookie(cookie)
}

Swift 3.0

if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        NSLog("\(cookie)")
    }
}

let storage = HTTPCookieStorage.shared
for cookie in storage.cookies! {
    storage.deleteCookie(cookie)
}

保存Cookie

func saveCookies() {
    guard let cookies = HTTPCookieStorage.shared.cookies else {
        return
    }
    let array = cookies.flatMap { (cookie) -> [HTTPCookiePropertyKey: Any]? in
        cookie.properties
    }
    UserDefaults.standard.set(array, forKey: "cookies")
    UserDefaults.standard.synchronize()
}

加载Cookie ：

func loadCookies() {
    guard let cookies = UserDefaults.standard.value(forKey: "cookies") as? [[HTTPCookiePropertyKey: Any]] else {
        return
    }
    cookies.forEach { (cookie) in
        guard let cookie = HTTPCookie.init(properties: cookie) else {
            return
        }
        HTTPCookieStorage.shared.setCookie(cookie)
    }
}

您可以像下面的代码一样调用这些函数

func webViewDidStartLoad(_ webView: UIWebView) {
    loadCookies()
}

func webViewDidFinishLoad(_ webView: UIWebView) {
    saveCookies()
}

不要忘记为 webViewDidStartLoad 和 webViewDidFinishLoad

设置WebView代理

Answer 3

感谢swift＆＃34;翻译＆＃34; ...只需要将删除更改为！强迫垂头丧气：

var storage : NSHTTPCookieStorage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
for cookie in storage.cookies  as! [NSHTTPCookie]
{
    storage.deleteCookie(cookie)
}
NSUserDefaults.standardUserDefaults()

Answer 4

以下是如何使用UIWebView的委托功能捕获cookie的完整答案：

sub maximum($) {
    ($num1) = @_ ; 
    ($num2) = @_ ; 
    ($num2) = @_ ; 

    $max = $num1;

    if ($num2 > $num1) {
        $max = $num2;
    }    
    elsif ($num3 > $max ) {
        $max = $num3;
    }
}

$n1 = $ARGV[0];
chomp($n1);
$n2 = $ARGV[1];
chomp($n2);
$n3 = $ARGV[2];
chomp($n3);

maximum($n1, $n2, $n3);

请记住，Cookie将保存为默认值，此委托函数会调用webview加载完成的所有移动。（它还使用 Swift 3.0.1 进行了更新）

Answer 5

如果您正在使用 swift 4 ，则此代码将停用 Cookie ，并删除网址缓存。

let cookieJar : HTTPCookieStorage = HTTPCookieStorage.shared
for cookie in cookieJar.cookies! as [HTTPCookie]{
    NSLog("cookie.domain = %@", cookie.domain)
     cookieJar.deleteCookie(cookie)
}

URLCache.shared.removeAllCachedResponses() 
URLCache.shared.diskCapacity = 0 
URLCache.shared.memoryCapacity = 0

Answer 6

swift 3

    let storage = HTTPCookieStorage.shared

    for cookie in storage.cookies! {
        storage.deleteCookie(cookie)
    }

Answer 7

退出api VKontakte，swift 3 +

let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { (records) in
    for record in records {
        if record.displayName.contains("facebook") {
            dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), for: [record], completionHandler: {
                print("Deleted: " + record.displayName);
            })
        }
    }
}
