在APP开发中，cookie也开始变的越来越重要了。为了更好的切换，注销和登录账户，就必须熟悉cookie的用法。
花了点时间把代码整理了一下，注释也都标上了
1，获取cookie
获取cookie只能在请求中获取cookie，否则时获取不到的，url就不给出了，大家用自己的url测试一下就行。
获取到cookie后把cookie进行归档保存到userDefaults里

#pragma mark 获取并保存cookie到userDefaults- (void)getAndSaveCookie{ NSLog(@"=============获取cookie=============="); NSString *urlString = @""; //请求一个网址，即可分配到cookie AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFJSONResponseSerializer new]; [manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { //获取cookie NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; for (NSHTTPCookie *tempCookie in cookies) { //打印获得的cookie NSLog(@"getCookie: %@", tempCookie); } /* * 把cookie进行归档并转换为NSData类型 * 注意：cookie不能直接转换为NSData类型，否则会引起崩溃。 * 所以先进行归档处理，再转换为Data */ NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]]; //存储归档后的cookie NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setObject: cookiesData forKey: @"cookie"]; NSLog(@"\n"); [self deleteCookie]; [self setCoookie]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { nil; }];} |
2，删除cookie
把获取到的cookie删除掉，该步骤可以用在注销或者切换账号里。
当前，我这里删除cookie是为了检测后面的通过本地存储的数据进行设置cookie是否成功

#pragma mark 删除cookie- (void)deleteCookie{ NSLog(@"============删除cookie==============="); NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; //删除cookie for (NSHTTPCookie *tempCookie in cookies) { [cookieStorage deleteCookie:tempCookie]; } //把cookie打印出来，检测是否已经删除 NSArray *cookiesAfterDelete = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; for (NSHTTPCookie *tempCookie in cookiesAfterDelete) { NSLog(@"cookieAfterDelete: %@", tempCookie); } NSLog(@"\n");} |
3，通过本地存储的数据设置cookie
把本地的cookie取出并反归档，设置到cookie中，并且检测cookie是否设置成功

#pragma mark 再取出保存的cookie重新设置cookie- (void)setCoookie{ NSLog(@"============再取出保存的cookie重新设置cookie==============="); //取出保存的cookie NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; //对取出的cookie进行反归档处理 NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData:[userDefaults objectForKey:@"cookie"]]; if (cookies) { NSLog(@"有cookie"); //设置cookie NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; for (id cookie in cookies) { [cookieStorage setCookie:(NSHTTPCookie *)cookie]; } }else{ NSLog(@"无cookie"); } //打印cookie，检测是否成功设置了cookie NSArray *cookiesA = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; for (NSHTTPCookie *cookie in cookiesA) { NSLog(@"setCookie: %@", cookie); } NSLog(@"\n");} |
看一下运行截图
最后，奉上demo
