Ios 一种嵌套NSDictionary的afpost方法,ios,json,afnetworking-2,Ios,Json,Afnetworking 2,我正在使用AF网络2。我想将嵌套的NSMutableDictionary发送到服务器。这就是我正在使用的方法 NSMutableArray *arrayRecordSet =[NSMutableArray array]; for (id contact in _contactGroupArr) { ContactGroup *contactGroup=contact; NSMutableDictionary *dictGroupDetails=[NSM

我正在使用AF网络2。我想将嵌套的

NSMutableDictionary

发送到服务器。这就是我正在使用的方法

NSMutableArray *arrayRecordSet =[NSMutableArray array];
    for (id contact in _contactGroupArr) {

        ContactGroup *contactGroup=contact;

        NSMutableDictionary *dictGroupDetails=[NSMutableDictionary dictionary];
        [dictGroupDetails setObject:contactGroup.guid forKey:@"guid"];
        [dictGroupDetails setObject:contactGroup.name forKey:@"name"];
        [dictGroupDetails setObject:@"" forKey:@"description"];
        [dictGroupDetails setObject:contactGroup.status forKey:@"isDeleted"];

        NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
        [dictContactGroup setObject:dictGroupDetails forKey:@"contact_group"];

        [arrayRecordSet addObject:dictContactGroup];

    }

    NSMutableDictionary *dictSyncData=[[NSMutableDictionary alloc]init];
    [dictSyncData setObject:arrayRecordSet forKey:@"recordset"];
    [dictSyncData setValue:@"2014-06-30 04:47:45" forKey:@"last_sync_date"];

    NSString *getPath = [NSString stringWithFormat:API_SYNC_CONATCTGROUP];

    [self POST:getPath parameters:dictSyncData
       success:^(NSURLSessionDataTask *task, id responseObject) {

           NSLog(@"%@",responseObject);
       }
       failure:^(NSURLSessionDataTask *task, NSError *error) {
           NSLog(@"%@",error);
       }];

但需要Json格式的服务器是

Array
(
    [last_sync_date] => 2014-06-30 04:47:45
    [recordset] => Array
        (
            [0] => Array
                (
                    [contact_group] => Array
                        (
                            [guid] => y37845y8y
                            [name] => Family
                            [description] => Family members
                            [isDeleted] => 0
                        )

                )

            [1] => Array
                (
                    [contact_group] => Array
                        (
                            [guid] => gt45tergh4
                            [name] => Office
                            [description] => Office members
                            [isDeleted] => 0
                        )

                )

        )

)

但是我的代码发送了错误的格式

但是我检查了我的

NSMutableDictionary

。这是正确的。因为我手动创建了

NSJson

字符串。它将给出正确的格式。我创建了错误的json格式

我全力以赴。但我还是有问题

编辑

服务器需要json

{  

    "last_sync_date": "2014-06-30 04:47:45",

    "recordset": [

        {

            "contact_group": {

                "guid": "y37845y8y",

                "name": "Family",        

                "description": "Family members",              

                "isDeleted": 0        

            } 

        },

        {

            "contact_group": { 

                "guid": "gt45tergh4",        

                "name": "Office",        

                "description": "Office members",              

                "isDeleted": 0        

            } 

        } 

    ]

}

看起来您在零件中缺少了一个额外的层：

NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
[dictContactGroup setObject:dictGroupDetails forKey:@"contact_group"];

我认为您需要包装您的：

dictGroupDetails

进入另一个数组，然后将该数组设置为dictContactGroup的对象，如下所示：

NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init]; 

NSArray *wrapperArray = @[dictGroupDetails];

[dictContactGroup setObject:wrapperArray forKey:@"contact_group"];

你明白我的意思吗

额外编辑1 忘了还提到，从您假定的预期输出来看，arrRecordSet中的每个元素似乎都包含一个联系人组数组

您可能还需要将您的联系人组本身包装在外部包装器阵列中：

NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init]; 

NSArray *wrapperArray = @[dictGroupDetails];

[dictContactGroup setObject:wrapperArray forKey:@"contact_group"];

// notice the extra @[ ]  wrapped around "dictContactGroup"
[arrayRecordSet addObject:@[dictContactGroup]];

额外编辑2 我不确定您上面提供的“预期输出”是否准确，您似乎已经手动输入了它

我已经编写了一个快速演示应用程序来测试上述逻辑：

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    NSMutableArray *arrRecordSet = [[NSMutableArray alloc] init];

    NSArray *arrContactGroups = @[@0, @1, @2, @3, @4, @5];

    for(int i = 0; i < arrContactGroups.count; i++)
    {
        NSMutableDictionary *dictGroupDetails=[NSMutableDictionary dictionary];
        [dictGroupDetails setObject:@"1234" forKey:@"guid"];
        [dictGroupDetails setObject:@"group name" forKey:@"name"];
        [dictGroupDetails setObject:@"group description" forKey:@"description"];
        [dictGroupDetails setObject:@"not deleted" forKey:@"isDeleted"];

        NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
        [dictContactGroup setObject:@[dictGroupDetails] forKey:@"contact_group"];

        [arrRecordSet addObject:@[dictContactGroup]];
    }

    NSMutableDictionary *dictSyncData=[[NSMutableDictionary alloc]init];
    [dictSyncData setObject:arrRecordSet forKey:@"recordset"];
    [dictSyncData setValue:@"2014-06-30 04:47:45" forKey:@"last_sync_date"];

    NSLog(@"dictSyncData = \n\n%@", dictSyncData);

}

这与您的预期输出相符，所以我认为在翻译过程中丢失了一些东西

您能否向我们提供应用程序控制台输出的实际结果，而不是手动键入的版本？

看起来您必须在另一个字典中扭曲

联系人组字典。试试这样的
int index = 0;

for (id contact in _contactGroupArr) {

        ContactGroup *contactGroup=contact;

        //level 1
        NSMutableDictionary *dictGroupDetails=[NSMutableDictionary dictionary];
        [dictGroupDetails setObject:contactGroup.guid forKey:@"guid"];
        [dictGroupDetails setObject:contactGroup.name forKey:@"name"];
        [dictGroupDetails setObject:@"" forKey:@"description"];
        [dictGroupDetails setObject:contactGroup.status forKey:@"isDeleted"];

        //level 2
        NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
        [dictContactGroup setObject:dictGroupDetails forKey:@"contact_group"];

        //level 3
        NSMutableDictionary *dictArry=[[NSMutableDictionary alloc]init];
        [dictArry setObject:dictContactGroup forKey:[NSString stringWithFormat:@"%d",index]];

        [arrayRecordSet addObject:dictArry];

        index ++;

    }

在这里，我在第3级所做的是将dictContactGroup
NSMutableDictionary包装到另一个名为dictArry
的NSMutableDictionary中，使JSON对象结构如下所示
    [0] => Array
    (
       [contact_group] => Array
         (
            [guid] => y37845y8y
            [name] => Family
            [description] => Family members
            [isDeleted] => 0
         )

    )

[上次同步日期]=>2014-06-30 04:47:45[记录集]=>Array（[0]=>Array（[0]=>Array（[0]=>Array（[description]=>）））[1]=>Array（[0]=>Array（[guid]=>8D9763F6-38EF-49C7-860D-62759D77A779）），也就是说，不确定这是否有帮助，但您是使用[AFJSONRequestSerializer]将响应作为JSON发送到服务器，还是使用[AFHTTPRequestSerializer]序列化程序？我尝试了所有的方法。但都不起作用。检查编辑的版本。我附加了服务器所需的json格式。我认为这会对您有所帮助。您还可以使用NSLog（@“dictSyncData=\n\n%@”，dictSyncData）的真实控制台日志结果编辑您的问题；就在NSString*getPath=[NSString stringWithFormat:API\u SYNC\u CONATCTGROUP]行之前？[\u contactGroupArr enumerateObjectsUsingBlock:^（id obj，整数idx，布尔*停止）{
    [0] => Array
    (
       [contact_group] => Array
         (
            [guid] => y37845y8y
            [name] => Family
            [description] => Family members
            [isDeleted] => 0
         )

    )
