iOS Cookie的配置及使用

本文介绍iOS中cookie的使用包含AFNetWorking 3.0中的使用，常用于登录状态信息保存

• 从 NSHTTPCookieStorage 获取想要Cookie，此种获取方式是获取的cookies中的

//获取cookie
    NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage]cookiesForURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",kBaseURL,[NSString stringWithFormat:@"/index.php?route=mapi/%@",urlstring]]]];
    for (NSHTTPCookie *tempCookie in cookies)
    {
        //打印cookies
        NSLog(@"getCookie:%@",tempCookie);
    }
    NSDictionary *Request = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
    
    NSUserDefaults *userCookies = [NSUserDefaults standardUserDefaults];
    
    [userCookies setObject:[Request objectForKey:@"Cookie"] forKey:@"cookie"];
    [userCookies synchronize];

• 清除Cookie

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

使用 AFNetworking 时，对Cookies管理的示例

• AFNetworking 3.0 默认是保存cookies的。
• 模拟登录，保存cookie以及设置cookie:

NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
    AFHTTPSessionManager *httpManager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:@"hostURL"] sessionConfiguration:sessionConfiguration];
    AFHTTPRequestSerializer *requestSerialization = [AFHTTPRequestSerializer serializer];
    requestSerialization.timeoutInterval = 15;

    // 设置自动管理Cookies
    requestSerialization.HTTPShouldHandleCookies = YES;

    // 如果已有Cookie, 则把你的cookie符上
    NSString *cookie = [[NSUserDefaults standardUserDefaults] objectForKey:@"Set-Cookie"];
        if (cookie != nil) {
            [requestSerialization setValue:cookie forHTTPHeaderField:@"Set-Cookie"];
        }

    // 安全策略
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
    securityPolicy.allowInvalidCertificates = YES;
    securityPolicy.validatesDomainName = NO;

    [httpManager POST:@"logInURL"
           parameters:nil
             progress:NULL
              success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                  if ([responseObject[@"status"] isEqualToString:@"SUCCESS"]) {
                      //获取 Cookie
                      NSHTTPURLResponse* response = (NSHTTPURLResponse* )task.response;
                      NSDictionary *allHeaderFieldsDic = response.allHeaderFields;
                      NSString *setCookie = allHeaderFieldsDic[@"Set-Cookie"];
                      if (setCookie != nil) {
                          NSString *cookie = [[setCookie componentsSeparatedByString:@";"] objectAtIndex:0];
                          // 这里对cookie进行存储
                          [[NSUserDefaults standardUserDefaults] setObject:cookie forKey:@"cookie"];
                      }
                  }else{
                      // 登录失败
                  }
              }
              failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                  NSString *errorMessage = error.userInfo[@"NSLocalizedDescription"];
              }];
