iOS原生請求獲取Cookie值

以前用到兩個請求，第一個請求返回cookie值，須要保存起來，第二個請求須要帶第一個請求的cookie值這種狀況，如今有時間就整理了一下

獲取請求返回值中的cookie

 1     //建立URL
 2     NSURL * url = [NSURL URLWithString:@"http://api.skyfox.org/api-test.php"];
 3     
 4     //建立request請求
 5     NSURLRequest * request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:3];
 6     
 7     //初始化請求隊列
 8     NSOperationQueue *queue = [NSOperationQueue mainQueue];
 9     
10     [NSURLConnection sendAsynchronousRequest:request
11                                        queue:queue
12                            completionHandler:
13      ^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
14          
15          //轉換NSURLResponse成爲HTTPResponse
16          NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
17          
18          //獲取headerfields
19          
20          //原生NSURLConnection寫法
21          NSDictionary *fields = [httpResponse allHeaderFields];
22          
23          //afnetworking寫法
24          //NSDictionary *fields = [operation.response allHeaderFields];
25          
26          
27          //獲取cookie方法1
28          NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:fields forURL:url];
29       
30          for (NSHTTPCookie * cookie in cookies) {
31              
32              NSDictionary * cookieDic = [cookie properties];
33              NSLog(@"%@",cookieDic);
34          }
35          
36          //獲取cookie方法2
37          /*
38           NSString *cookieString = [[httpResponse allHeaderFields] valueForKey:@"Set-Cookie"];
39           */
40          
41          
42          //獲取cookie方法3
43          /*
44           NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
45           
46           for (NSHTTPCookie *cookie in [cookieJar cookies])
47           {
48           NSLog(@"cookie%@", cookie);
49           }
50           */
51     }];

第二個請求添加cookie方法

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