1. NSHTTPCookieStorage和NSHttpCookie

2. UIWebView Cookie

3. WKWebView Cookie

4. WKWebView Cookie 写入

WKUserContentController* userContentController = WKUserContentController.new;
WKUserScript * cookieScript = [[WKUserScript alloc] initWithSource: @"document.cookie ='TeskCookieKey1=TeskCookieValue1';document.cookie = 'TeskCookieKey2=TeskCookieValue2';"injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];

[userContentController addUserScript:cookieScript];
WKWebViewConfiguration* webViewConfig = WKWebViewConfiguration.new;
webViewConfig.userContentController = userContentController;
WKWebView * webView = [[WKWebView alloc] initWithFrame:CGRectMake(/*set your values*/) configuration:webViewConfig];
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation {
    [webView evaluateJavaScript:@"document.cookie ='TeskCookieKey1=TeskCookieValue1';" completionHandler:^(id result, NSError *error) {
        //...
    }];
}
NSMutableURLRequest *request= [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://dev.skyfox.org/cookie.php"]];
//[request setHTTPShouldHandleCookies:YES];
[request setValue:[NSString stringWithFormat:@"%@=%@",@"testwkcookie", @"testwkcookievalue"] forHTTPHeaderField:@"Cookie"];
  1. JS注入的Cookie,比如PHP代码在Cookie容器中取是取不到的, javascript document.cookie能读取到,浏览器中也能看到。

  2. NSMutableURLRequest 注入的PHP等动态语言直接能从$_COOKIE对象中获取到,但是js读取不到,浏览器也看不到

  3. 所以合理的办法让js,php,浏览器都能读取到相同的Cookie方法就是创建WebView的时候javascript注入Cookie,一开始发送NSMutableURLRequest请求的时候也要加上Cookie,并且保证两个地方的设置的cookie一致。

//初始化
WKUserContentController* userContentController = WKUserContentController.new;
WKUserScript * cookieScript = [[WKUserScript alloc] initWithSource: @"document.cookie ='TeskCookieKey3=TeskCookieValue3';"injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
 
[userContentController addUserScript:cookieScript];
WKWebViewConfiguration* webViewConfig = WKWebViewConfiguration.new;
webViewConfig.userContentController = userContentController;
WKWebView * webView = [[WKWebView alloc] initWithFrame:CGRectMake(/*set your values*/) configuration:webViewConfig];
 
//请求
NSMutableURLRequest *request= [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://dev.skyfox.org/cookie.php"]];
//[request setHTTPShouldHandleCookies:YES];
[request setValue:[NSString stringWithFormat:@"%@=%@",@"TeskCookieKey3", @"TeskCookieValue3"] forHTTPHeaderField:@"Cookie"];
[webView loadRequest:request];

5. WKWebsiteDataStore

WKWebsiteDataStore在iOS 9和OS X 10.11中引入,是一个新的API,它用于管理一个网站站点存储的数据,例如Cookies,它是你网页的 WKWebViewConfiguration上的一个可读写的属性。你可以根据类型或者时间来删除数据,例如Cookies和缓存,你可以用非持久性数 据存储来改变配置。

6. WKWebView Cookie 读取

因为cookie都存在http respone的headerfields,找到能获得respone的WKWebView回调,打印..

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler{
    NSHTTPURLResponse *response = (NSHTTPURLResponse *)navigationResponse.response;
    NSArray *cookies =[NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:response.URL];
    //读取wkwebview中的cookie 方法1
    for (NSHTTPCookie *cookie in cookies) {
//        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
        NSLog(@"wkwebview中的cookie:%@", cookie);
 
    }
    //读取wkwebview中的cookie 方法2 读取Set-Cookie字段
    NSString *cookieString = [[response allHeaderFields] valueForKey:@"Set-Cookie"];
    NSLog(@"wkwebview中的cookie:%@", cookieString);
 
    //看看存入到了NSHTTPCookieStorage了没有
    NSHTTPCookieStorage *cookieJar2 = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    for (NSHTTPCookie *cookie in cookieJar2.cookies) {
        NSLog(@"NSHTTPCookieStorage中的cookie%@", cookie);
    }
    decisionHandler(WKNavigationResponsePolicyAllow);
}

结果确实读取到了Cookie,但是打印NSHTTPCookieStorage单例中Cookie发现并没有任何Cookie。

7.WKWebsiteDataStore iOS9

- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
    WKWebsiteDataStore *dataStore = [WKWebsiteDataStore defaultDataStore];
    [dataStore fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes]
                     completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) {
                         for (WKWebsiteDataRecord *record  in records)
                         {
                             NSLog(@"WKWebsiteDataRecord:%@",[record description]);
                         }
                     }];
    
}

8. WKHTTPCookieStore iOS11

在iOS11中,苹果新增加了用于WKWebview Cookie存取操作的WKHTTPCookieStore。

A WKHTTPCookieStore object allows managing the HTTP cookies associated with a particular WKWebsiteDataStore.
