iOS-HTTP协议使用cookie

1、平时浏览访问一个网站时，NSURLRequest都会帮你主动记录下来你访问的站点设置的cookie，当你下次再访问这个站点时，NSURLRequest会拿着上次保存下来了的cookie继续去请求。之前以为手机是不存在cookie的，但是看了一些博客文章，发现其实也能输出cookie的。

// 1.创建一个网络路径
 NSURL *url = [NSURL URLWithString:@"http://www.baidu.com"];
 // 2.创建一个网络请求
 NSURLRequest *request = [NSURLRequest requestWithURL:url
 cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
 timeoutInterval:3];
 // 3.获得会话对象
 NSURLSession *session = [NSURLSession sharedSession];
 // 4.根据会话对象，创建一个Task任务：
 NSURLSessionDataTask *sessionDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
 // NSLog(@"从服务器获取到数据");
 // 
 // /*
 // 对从服务器获取到的数据data进行相应的处理：
 // */
 // NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:(NSJSONReadingMutableLeaves) error:nil];
 
 }];
 
 // 5.最后一步，执行任务（resume也是继续执行）:
 [sessionDataTask resume];
 
 //输出cookie
 NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
 for (NSHTTPCookie *cookie in [cookieJar cookies]) {
 NSLog(@"%@", cookie);
 }

最后会看到控制台输出的cookie内容如下：

2016-06-15 20:34:08.017 cookie[1099:37861] <NSHTTPCookie version:0 name:"BD_NOT_HTTPS" value:"1" expiresDate:2016-06-15 12:29:54 +0000 created:2016-06-15 12:24:54 +0000 sessionOnly:FALSE domain:"www.baidu.com" path:"/" isSecure:FALSE>
 2016-06-15 20:34:08.019 cookie[1099:37861] <NSHTTPCookie version:0 name:"BIDUPSID" value:"644741F6E4EB97BB49CD4064752A819F" expiresDate:2084-07-03 15:38:23 +0000 created:2016-06-15 12:24:16 +0000 sessionOnly:FALSE domain:".baidu.com" path:"/" isSecure:FALSE>
 2016-06-15 20:34:08.019 cookie[1099:37861] <NSHTTPCookie version:0 name:"PSTM" value:"1465993436" expiresDate:2084-07-03 15:38:23 +0000 created:2016-06-15 12:24:16 +0000 sessionOnly:FALSE domain:".baidu.com" path:"/" isSecure:FALSE>

2、清空cookie代码

NSHTTPCookieStorage *cookie = [NSHTTPCookieStorage sharedHTTPCookieStorage];
 NSArray *_tmpArray = [NSArray arrayWithArray:[cookie cookies]];
 for (id obj in _tmpArray) {
 [cookieJar deleteCookie:obj];
 }

3、设置cookie代码

NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
 [cookieProperties setObject:@"username" forKey:NSHTTPCookieName];
 [cookieProperties setObject:@"ming" forKey:NSHTTPCookieValue];
 [cookieProperties setObject:@"http://write.blog.csdn.net/postlist" forKey:NSHTTPCookieDomain];
 [cookieProperties setObject:@"http://write.blog.csdn.net/postlist" forKey:NSHTTPCookieOriginURL];
 [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
 [cookieProperties setObject:@"1" forKey:NSHTTPCookieVersion];
 
 NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
 [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
 NSLog(@"%@", cookie);

打印输出如下：
