一般在web与js的交互中想再post时需要拿到web里的用户信息,登录状态等,需要传递web的cooki
wk设置-->wk获取-->存储-->af取-->af设置

wkwebview的处理

  WKWebViewConfiguration *config                           = [WKWebViewConfiguration new];
// 设置偏好设置
config.preferences                                       = [WKPreferences new];
// 默认为0
config.preferences.minimumFontSize                       = 10;
// 默认为yes
config.preferences.javaScriptEnabled                     = YES;
// 在iOS上默认为NO，表示不能自动通过窗口打开
config.preferences.javaScriptCanOpenWindowsAutomatically = NO;
// web内容处理池
config.processPool                                       = [[WKProcessPool alloc] init];
// 注入JS对象名称AppModel，当JS通过AppModel来调用时，
// 我们可以在WKScriptMessageHandler代理中接收到
userContentController = [[WKUserContentController alloc]init];
config.userContentController = userContentController;

[userContentController addScriptMessageHandler:self name:@"AppModel"];
 

WKWebView *wkWebView         = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) configuration:config];
wkWebView.autoresizingMask   = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
wkWebView.backgroundColor    = [UIColor whiteColor];
wkWebView.navigationDelegate = self;
wkWebView.UIDelegate = self;

(这里是添加cookie(重点代码))
WKUserScript * cookieScript = [[WKUserScript alloc] initWithSource: @"document.cookie ='TeskWKCookieKey1=TeskWKCookieValue1';document.cookie = 'TeskWKCookieKey2=TeskWKCookieValue2';"injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
[userContentController addUserScript:cookieScript];
NSMutableURLRequest *request= [NSMutableURLRequest requestWithURL:[NSURL URLWithString:baseUrl]];
[request setValue:[NSString stringWithFormat:@"%@=%@",@"testWKcookie", @"testWKcookievalue"] forHTTPHeaderField:@"Cookie"];
 (把我想象成一条分割线呀~~~)

[wkWebView loadRequest:request];   
 self.wKWebView               = wkWebView;

Delegate(重点代码)

- (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];

/////////////// 存cookie(主要是这里)
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:cookies];
[[NSUserDefaults standardUserDefaults] setObject:data forKey:@"WebViewCookie"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSLog(@"存:cookies : %@",cookies);
(把我想象成一条分割线呀~~~)

//读取wkwebview中的cookie 方法1
for (NSHTTPCookie *cookie in cookies) {
    //        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
 //   NSLog(@"webview ---- %@", 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);
  //  NSLog(@"webview ---- %@", cookie);
}    
decisionHandler(WKNavigationResponsePolicyAllow);
}

Afnetworking处的处理

  AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setSecurityPolicy:securityPolicy];

[manager.requestSerializer setHTTPShouldHandleCookies:NO];


manager.responseSerializer = [AFHTTPResponseSerializer serializer];

//////////////设置web的cookie给af(重点代码)
 NSData *cookiesdata = [[NSUserDefaults standardUserDefaults] objectForKey:@"WebViewCookie"];
if([cookiesdata length]) {
    NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData:cookiesdata];
    NSHTTPCookie *cookie;
    for (cookie in cookies) {
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
        
        NSLog(@"取:cookies : %@",cookies);
    }  
}

(把我想象成一条分割线呀~~~)

[manager POST:url parameters:body progress:^(NSProgress * _Nonnull uploadProgress) {
    
    
} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    if (success) {
        
        success(task, responseObject);
        
        NSDictionary *fields = ((NSHTTPURLResponse*)task.response).allHeaderFields;
       // NSLog(@"post --- fields = %@",[fields description]);
       // NSURL *url = [NSURL URLWithString:@"http://dev.skyfox.org/cookie.php"];
        //获取cookie方法1
        NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:fields forURL:[NSURL URLWithString:url]];
        for (NSHTTPCookie *cookie in cookies) {
          //  NSLog(@"post --- cookie,name:= %@,valuie = %@",cookie.name,cookie.value);
        }
    }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    if (failure) {
        
        failure(task, error);

    }
    
}]
