如何删除 WKWebview cookies

Question

目前我是这样做的

    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 clean cookie 有没有其他方式？任何帮助将不胜感激。谢谢。

Answer 1

iOS8.2 中似乎正在使用 NSHTTPCookieStorage 来根据需要正确清除 cookie。在打开基于 WKWebView 的登录之前，我发布了一个应用程序运行此代码：

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

早于 iOS 8.2 的网站会使用保存的 cookie 自动登录，现在它会正确地要求用户重新登录。所有这一切都发生在我没有发布应用程序更新的情况下。 :)

Answer 2

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

Answer 3

Apple 为 iOS 9 发布了新的 API，因此现在我们可以删除为 [=31] 存储的域特定 cookie =]WKWebView 使用以下代码，但这仅适用于具有 iOS 的设备版本 9 or 后来:

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);
             }
         ];
       }
     }
   }
 ];

以上代码段肯定适用于 iOS 9 及更高版本。不幸的是，如果我们在 iOS 之前的 iOS 版本中使用 WKWebView 9，我们还是要坚持传统的方法，删除整个cookie存储如下。

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

下面是Swift3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Swift 4：

let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
  dataStore.removeData(
    ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
    for: records.filter { [=13=].displayName.contains("facebook") },
    completionHandler: completion
  )
}

Answer 4

在iOS9中：

//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
                        WKWebsiteDataTypeDiskCache,
                        //WKWebsiteDataTypeOfflineWebApplicationCache,
                        WKWebsiteDataTypeMemoryCache,
                        //WKWebsiteDataTypeLocalStorage,
                        //WKWebsiteDataTypeCookies,
                        //WKWebsiteDataTypeSessionStorage,
                        //WKWebsiteDataTypeIndexedDBDatabases,
                        //WKWebsiteDataTypeWebSQLDatabases
                        ]];
//// All kinds of data
//NSSet *websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
//// Date from
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
//// Execute
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
    // Done
    NSLog(@"remove done");
}];

Answer 5

Swift版本：

var libraryPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.LibraryDirectory, NSSearchPathDomainMask.UserDomainMask, false).first!
libraryPath += "/Cookies"

do {
  let result = try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
  print(result)
} catch {
  print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()

Answer 6

Esqarrouth 的回答只对了一部分。
正确的 swift 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()

Answer 7

None 这些选项对我有用，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)

Answer 8

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。

还是IOS8用的是WKwebview，这个方法不适用..

Swift 3 版萨拉特的回答：

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: {

}

Answer 10

Swift 4 和更短的版本：

let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
    dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
                         for: records.filter { [=10=].displayName.contains("facebook") },
                         completionHandler: completion)
}

Answer 11

支持iOS11.0及以上

以下解决方案对我来说效果很好：

第 1 步。从 HTTPCookieStorage

中删除 Cookie

第 2 步。从 WKWebsiteDataStore 中获取数据记录并删除它们。

第 3 步。创建一个新的 WKProcessPool

创建 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()
    }

Answer 12

在 WKWebView 中有问题写入和读取它需要一些时间，所以当你获取 cookie 的时候你会得到更新的 cookie 但有时它会是旧的，你会得到错误任何服务器请求。我在 3 天内遇到了这个问题，

解决方案：无需在WKWebsiteDataStore中存储cookie。

正在获取 cookie：

Swift:

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)
        }
    }
}

Objective-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);
        }];
    }
}

每次你想要新的cookie所以你需要写下面的代码：鉴于 Sharpio

Swift :

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)

Objective C--

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


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

*******每次你都会得到新的cookies********

Answer 13

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 'default' 存储的 cookie 和数据记录，您可以使用以下内容：

let dataStore = webView.configuration.websiteDataStore
let cookieStore = dataStore.httpCookieStore
cookieStore.getAllCookies {
    [=10=].forEach { cookie in
        cookieStore.delete(cookie)
    }
}
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
    records.forEach { record in
        dataStore.removeData(ofTypes: record.dataTypes, for: [record]) { }
    }
}

Answer 14

Swift 5

    /// old API cookies
    for cookie in HTTPCookieStorage.shared.cookies ?? [] {
        HTTPCookieStorage.shared.deleteCookie(cookie)
    }
    /// URL cache
    URLCache.shared.removeAllCachedResponses()
    /// WebKit cache
    let date = Date(timeIntervalSince1970: 0)
    WKWebsiteDataStore.default().removeData(
        ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
        modifiedSince: date,
        completionHandler:{})
