iOS原生请求获取Cookie值

之前用到两个请求，第一个请求返回cookie值，需要保存起来，第二个请求需要带第一个请求的cookie值这种情况，现在有时间就整理了一下

获取请求返回值中的cookie

    //创建URL
    NSURL * url = [NSURL URLWithString:@"http://api.skyfox.org/api-test.php"];
    
    //创建request请求
    NSURLRequest * request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:3];
    
    //初始化请求队列
    NSOperationQueue *queue = [NSOperationQueue mainQueue];
    
    [NSURLConnection sendAsynchronousRequest:request
                                       queue:queue
                           completionHandler:
     ^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
         
         //转换NSURLResponse成为HTTPResponse
         NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
         
         //获取headerfields
         
         //原生NSURLConnection写法
         NSDictionary *fields = [httpResponse allHeaderFields];
         
         //afnetworking写法
         //NSDictionary *fields = [operation.response allHeaderFields];
         
         
         //获取cookie方法1
         NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:fields forURL:url];
      
         for (NSHTTPCookie * cookie in cookies) {
             
             NSDictionary * cookieDic = [cookie properties];
             NSLog(@"%@",cookieDic);
         }
         
         //获取cookie方法2
         /*
          NSString *cookieString = [[httpResponse allHeaderFields] valueForKey:@"Set-Cookie"];
          */
         
         
         //获取cookie方法3
         /*
          NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
          
          for (NSHTTPCookie *cookie in [cookieJar cookies])
          {
          NSLog(@"cookie%@", cookie);
          }
          */
    }];

第二个请求添加cookie方法

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookieArray forURL:url mainDocumentURL:request.mainDocumentURL];
