AFN获取cookie与设置cookie

1获取cookie

<pre name="code" class="objc">[manager POST:requestUrl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {    /**     *  从response的HeaderField获得头文件，从头文件中通过NSHTTPCookie的cookiesWithResponseHeaderFields组成cookie的NSArray，将生成cookie的array，使用NSHttpCookie的reqeustHeaderFieldsWithCookies方法拼接成合法的http header field。最后set到request中即可。     [manager.requestSerializer setValue:[requestFields objectForKey:@"Cookie"] forHTTPHeaderField:@"Cookie"];     */    NSDictionary *fields= [operation.response allHeaderFields];    NSArray *cookies=[NSHTTPCookie cookiesWithResponseHeaderFields:fields forURL:[NSURL URLWithString:BaseURLString]];    NSDictionary* requestFields=[NSHTTPCookie requestHeaderFieldsWithCookies:cookies];    [[NSUserDefaults standardUserDefaults] setObject:[requestFields objectForKey:@"Cookie"] forKey:mUserDefaultsCookie];                // 使用jsonkit进行json解析    int result=[self jsonToUserDefault:operation];    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {    DLog(@"Error: %@", error);    // 使用Bl的 loginfailed方法    [_delegate loginFail];}];

2.设置cookie

<pre name="code" class="objc">[objc] view plain copy print?AFHTTPRequestOperationManager *manager           = [AFHTTPRequestOperationManager manager];manager.responseSerializer                       = [AFJSONResponseSerializer serializer];[manager.requestSerializer setValue: [[NSUserDefaults standardUserDefaults] objectForKey:mUserDefaultsCookie]forHTTPHeaderField:@"Cookie"];manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/html"];NSString* suffix=[NSString stringWithFormat:@"?m=user&a=edit&nickname=%@&age=%@",nickName,age];NSString* requestUrl                             =[BaseURLString stringByAppendingString:suffix];NSString* utf8=[requestUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];//将请求地址转换为utf8编码，使用默认unicode进行请求会报编码错误
