ios - 如何删除 WKWebview cookie

Question

现在我正在这样做

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

但它不适用于 iOS 8、64 位设备。

WKWebview的干净cookie还有其他方式吗？任何帮助将不胜感激。谢谢。

Apple 为iOS 9发布了新的 API，因此现在我们可以使用以下代码删除为WKWebView存储的域特定 cookie ，但这仅适用于iOS 9或更高版本的设备：

WKWebsiteDataStore *dateStore = [WKWebsiteDataStore defaultDataStore];
[dateStore
   fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes]
   completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) {
     for (WKWebsiteDataRecord *record  in records) {
       if ( [record.displayName containsString:@"facebook"]) {
         [[WKWebsiteDataStore defaultDataStore]
             removeDataOfTypes:record.dataTypes
             forDataRecords:@[record]
             completionHandler:^{
               NSLog(@"Cookies for %@ deleted successfully",record.displayName);
             }
         ];
       }
     }
   }
 ];

上面的代码片段肯定适用于iOS 9及更高版本。不幸的是，如果我们在iOS 9之前的 iOS 版本中使用WKWebView，我们仍然必须坚持传统的方法并删除整个 cookie 存储，如下所示。

NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"];
NSError *errors;
[[NSFileManager defaultManager] removeItemAtPath:cookiesFolderPath error:&errors];

下面是 Swift 3 版本

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);
                })
            }
        }
    }

和斯威夫特 4：

let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
  dataStore.removeData(
    ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
    for: records.filter { $0.displayName.contains("facebook") },
    completionHandler: completion
  )
}

支持iOS 11.0及以上

以下解决方案对我来说效果很好：

步骤 1. 移除 CookieHTTPCookieStorage

步骤 2. 从中获取数据记录WKWebsiteDataStore并删除它们。

步骤 3. 创建一个新的WKProcessPool

创建一个 WKWebView 扩展：

extension WKWebView {

    func cleanAllCookies() {
        HTTPCookieStorage.shared.removeCookies(since: Date.distantPast)
        print("All cookies deleted")

        WKWebsiteDataStore.default().fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
            records.forEach { record in
                WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record], completionHandler: {})
                print("Cookie ::: \(record) deleted")
            }
        }
    }

    func refreshCookies() {
        self.configuration.processPool = WKProcessPool()
    }
}

用法：

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(true)
        webView.cleanAllCookies()
        webView.refreshCookies()
    }

这些选项都不适合我，但我找到了一个：

let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
    config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {
     // I have no idea what to do for iOS 8 yet but this works in 9.
}

let webView = WKWebView(frame: .zero, configuration: config)

//// Execute

    // Done
    NSLog(@"remove done");
}];

除了清除共享cookie存储中的cookie之外，我还尝试清除缓存（NSURLCache）并丢弃WKWebView并使用新的WKProcessPool创建一个新的

在所有现有答案的基础上，如果您尝试清除特定 WKWebView 实例“webView”的 cookie 和数据记录，而不是“默认”存储的 cookie 和数据记录，则可以使用以下内容：

let dataStore = webView.configuration.websiteDataStore
let cookieStore = dataStore.httpCookieStore
cookieStore.getAllCookies {
    $0.forEach { cookie in
        cookieStore.delete(cookie)
    }
}
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
    records.forEach { record in
        dataStore.removeData(ofTypes: record.dataTypes, for: [record]) { }
    }
}

似乎 NSHTTPCookieStorage 现在正在 iOS 8.2 中用于根据需要正确清除 cookie。在打开基于 WKWebView 的登录之前，我已经发布了一个可以运行此代码的应用程序：

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

在 iOS 8.2 之前，网站会使用保存的 cookie 自动登录，现在它正确地要求用户重新登录。这一切都是在我没有向应用程序发送更新的情况下发生的。:)

Esqarrouth 的回答只是部分正确。
正确的快速版本是：

var libraryPath : String = NSFileManager().URLsForDirectory(.LibraryDirectory, inDomains: .UserDomainMask).first!.path!
libraryPath += "/Cookies"
do {
    try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
} catch {
    print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()

WKWebview 在 [NSHTTPCookieStorage sharedHTTPCookieStorage] 中不存储任何内容。

清除WKWebsiteDataStore将是解决此问题的方法。

仍然对于使用 WKwebview 的 IOS8，此方法不适用..

在 WKWebView 中，写入和读取需要一些时间，因此当您获取 cookie 时，您将获得更新的 cookie，但有时它会是旧的，并且您将在任何服务器请求上收到错误。我在 3 天内遇到了这个问题，

解决方案：无需在 WKWebsiteDataStore 中存储 cookie。

获取 cookie：

迅速：

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)
        }
    }
}

目标-c：

-(void )getAllCookies
{
    NSMutableString *updatedCockies= [[NSMutableString alloc] init];
    if (@available(iOS 11.0, *)) {
        WKHTTPCookieStore *cookieStore = _webView.configuration.websiteDataStore.httpCookieStore;
        NSLog(@"cookieStore *********************: %@",cookieStore);
        [cookieStore getAllCookies:^(NSArray* cookies) {
            NSHTTPCookie *cookie;
            for(cookie in cookies){
               NSLog(@"%@",cookie)
            }
            self->updatedCookie = updatedCockies;
            NSLog(@"cookie *********************: %@", self->updatedCookie);
        }];
    }
}

每次您想要新的 cookie 时，您都需要编写以下代码：Given Sharpio

斯威夫特：

let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
    config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {
     // I have no idea what to do for iOS 8 yet but this works in 9.
}

let webView = WKWebView(frame: .zero, configuration: config)

目标C——

WKWebViewConfiguration *wkWebConfig = [WKWebViewConfiguration new];
    wkWebConfig.websiteDataStore = [WKWebsiteDataStore nonPersistentDataStore];


self.webView = [[WKWebView alloc] initWithFrame: CGRectZero
                                      configuration: wkWebConfig];
