AFnetworking框架存储cookie和使用cookie请求总结

  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"];

使用以下代码进行请求，解析为cookie存入NSUserDefaults，全局单例类

[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];
    }];

在要使用时，从[NSUserDefaults standardUserDefaults]中取出，使用AFHTTPRequestOperationManager的[manager.requestSerializer setValue:   forHTTPHeaderField:];对NSMutableRequest的headerField中的cookie进行赋值。

 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
