wkwebview cookie同步

一、wkwebview之间同步

+(WKProcessPool *)shareWKProcessPool
{
    if (processPoll ==nil) {
        processPoll = [[WKProcessPoolalloc]init];
    }
    returnprocessPoll;
}

- (void)viewDidLoad {
    [superviewDidLoad];
    // Do any additional setup after loading the view.
    
    WKWebViewConfiguration *internalConfig = [[WKWebViewConfigurationalloc]init];
    internalConfig.processPool = [WKViewControllershareWKProcessPool];
    //WKUserContentController *contentController = [[WKUserContentController alloc] init];
    //internalConfig.userContentController = contentController;
    
    WKWebView *webView = [[WKWebViewalloc]initWithFrame:self.view.boundsconfiguration:internalConfig];
    [webView loadRequest:[NSURLRequestrequestWithURL:[NSURLURLWithString:@"http://localhost:81/test/indexcookie.html"]]];
    [self.viewaddSubview:webView];

    webView.navigationDelegate =self;
    webView.UIDelegate =self;
}

二、把UIWebView的cookie同步到WKWebView
方法1：

[internalConfig.userContentControllerremoveAllUserScripts];
    NSString *JSCookieString =@"document.cookie='name=value;domain=www.domain.com;expires=eee, dd MM yyyy HH:mm:ss;path=/'";
    WKUserScript * cookieScript = [[WKUserScriptalloc]
                                   initWithSource:JSCookieString
                                   injectionTime:WKUserScriptInjectionTimeAtDocumentStartforMainFrameOnly:NO];
    [internalConfig.userContentControlleraddUserScript:cookieScript];

WKWebView *webView = [[WKWebViewalloc] initWithFrame:self.view.boundsconfiguration:internalConfig];
    [webView loadRequest:[NSURLRequestrequestWithURL:[NSURLURLWithString:@"http://localhost:81/test/indexcookie.html"]]];

方法2：

NSMutableURLRequest * request = [NSMutableURLRequest
requestWithURL:[NSURL
URLWithString:@"http://localhost:81/test/indexcookie.html"]];
      [request addValue:@"name=value;...;..." forHTTPHeaderField:@"Cookie"];
    [webView loadRequest:request];

方法3：
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation
{
//    [webView evaluateJavaScript:@"document.cookie ='TeskCookieKey1=TeskCookieValue1';" completionHandler:^(id result, NSError *error) {
//        //...
//    }];
    
    //思路是这样子的，我们可以通过NSHTTPCookieStorage的一个单例，拿到app中所有的UIWebView的cookie，拿到之后再通过让WKWebView执行一段js代码，把这些cookie设置到WKWebView中，这样就可以实现WKWebView获取UIWebView的cookie了。
    //取出cookie
    NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStoragesharedHTTPCookieStorage];
    //js函数
    NSString *JSFuncString =@"function setCookie(name,value,expires)\
    {\
    var oDate=new Date();\
    oDate.setDate(oDate.getDate()+expires);\
    document.cookie=name+'='+value+';expires='+oDate;\
    }";
    
    //拼凑js字符串
    NSMutableString *JSCookieString = JSFuncString.mutableCopy;
    for (NSHTTPCookie *cookiein cookieStorage.cookies)
{
        NSString *excuteJSString = [NSStringstringWithFormat:@"setCookie('%@',
'%@', 1);", cookie.name, cookie.value];
        [JSCookieString appendString:excuteJSString];
    }
    //执行js
    [webView evaluateJavaScript:JSCookieStringcompletionHandler:nil];
    
    
    //读取
    [webView evaluateJavaScript:[NSStringstringWithFormat:@"document.cookie"]completionHandler:^(id_Nullable
response, NSError *_Nullable error) {
        if (response !=0) {
            NSLog(@"\n\n document.cookie:%@,%@",response,error);
        }
    }];
}
