由于WKWebView實例不會把Cookie存入到App標準的的Cookie容器(HTTPCookieStorage)中, WKWebView擁有自己的私有存儲.

因為 NSURLSession/NSURLConnection等網(wǎng)絡(luò)請求使用HTTPCookieStorage進行訪問Cookie,所以不能訪問WKWebView的Cookie,現(xiàn)象就是WKWebView存了Cookie,其他的網(wǎng)絡(luò)類如NSURLSession/NSURLConnection卻看不到. 同時WKWebView也不會讀取存儲在HTTPCookieStorage中的Cookie.

要解決這一問題,通過JS的方式注入Cookie是對于我們目前的代碼來說是最合適也是最方便的. 因為我們已經(jīng)有了注入到HTTPCookieStorage的代碼, 那么只需要把這些Cookie轉(zhuǎn)化成JS并且注入到WKWebView里面就可以了拐袜。

fileprivate class func getJSCookiesString(_ cookies: [HTTPCookie]) -> String {
        var result = ""
        let dateFormatter = DateFormatter()
        dateFormatter.timeZone = TimeZone(abbreviation: "UTC")
        dateFormatter.dateFormat = "EEE, d MMM yyyy HH:mm:ss zzz"
        
        for cookie in cookies {
            result += "document.cookie='\(cookie.name)=\(cookie.value); domain=\(cookie.domain); path=\(cookie.path); "
            if let date = cookie.expiresDate {
                result += "expires=\(dateFormatter.string(from: date)); "
            }
            if (cookie.isSecure) {
                result += "secure; "
            }
            result += "'; "
        }
        return result
    }

注入的方法就是在每次initWkWebView的時候, 使用下面的config就可以了:

public class func wkWebViewConfig() -> WKWebViewConfiguration {
        let userContentController = WKUserContentController()
        if let cookies = HTTPCookieStorage.shared.cookies {
            let script = getJSCookiesString(cookies)
            let cookieScript = WKUserScript(source: script, injectionTime: WKUserScriptInjectionTime.atDocumentStart, forMainFrameOnly: false)
            userContentController.addUserScript(cookieScript)
        }
       //禁止長按彈出 UIMenuController 相關(guān)
       //禁止選擇 css 配置相關(guān)
        let css = "('body{-webkit-user-select:none;-webkit-user-drag:none;}')"
        //css 選中樣式取消
        let javaScript = NSMutableString()
        javaScript.append("var style = document.createElement('style');")
        javaScript.append("style.type = 'text/css';")
        javaScript.append("var cssContent = document.createTextNode\(css);")
        javaScript.append("style.appendChild(cssContent);")
        javaScript.append("document.body.appendChild(style);")
        javaScript.append("document.documentElement.style.webkitUserSelect='none';")//禁止選擇
        javaScript.append("document.documentElement.style.webkitTouchCallout='none';")//禁止長按
        let noneSelectScript = WKUserScript.init(source: javaScript as String, injectionTime: .atDocumentEnd, forMainFrameOnly: true)
        userContentController.addUserScript(noneSelectScript)
        let webViewConfig = WKWebViewConfiguration()
        webViewConfig.userContentController = userContentController
        
        return webViewConfig
    }
    
    public class func getJSCookiesString() -> String? {
        
        guard let cookies = HTTPCookieStorage.shared.cookies else {
            return nil
        }
        return getJSCookiesString(cookies)
    }

使用如下：

let config = CommonMethod.wkWebViewConfig()
var wkWebView = WKWebView.init(frame: CGRect(x:0,y:0,width:SCREEN_WIDTH,height:SCREEN_HEIGHT), configuration: config)
