【问题描述】：

NSDictionary *partyOne = [NSDictionary dictionaryWithObjectsAndKeys:
                              [NSNumber numberWithInt:2], @"type",
                              [NSNumber numberWithInt:1], @"status",
                              @"name", @"name",
                              @"name", @"nid",
                              @"name", @"nationality",
                              @"", @"address",
                              @"name", @"mobile",
                              nil];

    NSDictionary *partyTwo = [NSDictionary dictionaryWithObjectsAndKeys:
                              [NSNumber numberWithInt:2], @"type",
                              [NSNumber numberWithInt:1], @"status",
                              @"name", @"name",
                              @"name", @"nid",
                              @"name", @"nationality",
                              @"", @"address",
                              @"name", @"mobile",
                              nil];


    NSArray *partyArray = [NSArray arrayWithObjects: partyOne, partyTwo, nil];

   NSDictionary  *finalData =[NSDictionary dictionaryWithObject: partyArray forKey:@"details"];

当我将上述 NSDictionary 发送到 php 中的 AFNetworking 2 时，如下所示，

// Send the data to server
    NSDictionary *regDic = [self generteJasonData];

    // Send the registered data to server
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:userName password:userpassWd];
     manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager setShouldUseCredentialStorage:NO];

    NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:@"POST" URLString:@"http://testlink/submit"parameters:regDic];
    [request setHTTPShouldHandleCookies:NO];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    AFJSONResponseSerializer *serializer = [AFJSONResponseSerializer serializer];
    [operation setResponseSerializer:serializer ];
    [operation setShouldUseCredentialStorage:NO];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) 
        NSLog(@"Success: %@", responseObject);
        [manager.requestSerializer clearAuthorizationHeader];
        [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
        NSLog(@"Failure: %@ responce :%@", error,operation.responseString);
        [manager.requestSerializer clearAuthorizationHeader];
        [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"upload", @"")                                                                                         message:NSLocalizedString(@"Some error occureed while uploading data, please tryagain later", @"")
                                                       delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];


    ];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    [operation start];

我在我的 php 服务器上接收它，

details =             (
                                
                    address = "";
                ,
                                
                    mobile = name;
                ,
                               
                    name = name;
                ,
                                
                    nationality = name;
                ,
                                
                    nid = name;
                ,
                               
                    status = 1;
                ,
                                
                    type = 2;
                ,
                                
                    address = "";
                ,            
                    mobile = name;
                ,           
                    name = name;
                ,
                                
                    nationality = name;
                ,
                                
                    nid = name;
                ,
                       
                    status = 1;
                ,
                                
                    type = 2;
                ,
            );

即我发送了 2 个数组元素，但我收到的数组元素也一样多。 谁能让我知道这里有什么问题。他们是 AFNetworking 2.0 API 的问题还是我的代码有问题。

【问题讨论】：

这里NSDictionary *finalData =[NSDictionary dictionaryWithObject:arrayDictionary forKey:@"details"]; arrayDictionary 是什么？

@katre，我已经编辑了我的查询。它是“partyArray”

我遇到了同样的问题，Vaz，你找到解决方案了吗？

【参考方案1】：

好的，所以你需要做的就是修复方法

NSArray * AFQueryStringPairsFromKeyAndValue(NSString *key, id value)

在文件 AFURLRequestSerialization.m 中： 而不是

for (id nestedValue in array)

做起来

for (int i = 0;i < [array count];++i)

然后代替

[mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue([NSString stringWithFormat:@"%@[]", key], nestedValue)];

做起来

[mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue([NSString stringWithFormat:@"%@[%d]", key,i], nestedValue)];

【讨论】：

精湛的答案兄弟。我很震惊为什么这个答案不被接受，但你应该解释一下

老兄，你救了我的命 :)，我只花了半天时间来解决这个问题。非常感谢

【参考方案2】：

AFNetworking 2.0：我使用了@gilad 答案并对其进行了一些修改以使其正常工作。所以我所做的写在下面：

NSArray * AFQueryStringPairsFromKeyAndValue(NSString *key, id value) 
   NSMutableArray *mutableQueryStringComponents = [NSMutableArray array];

    NSSortDescriptor *sortDescriptor = [NSSortDescriptor    sortDescriptorWithKey:@"description" ascending:YES selector:@selector(compare:)];

  if ([value isKindOfClass:[NSDictionary class]]) 
    NSDictionary *dictionary = value;
    // Sort dictionary keys to ensure consistent ordering in query string, which is important when deserializing potentially ambiguous sequences, such as an array of dictionaries
    for (id nestedKey in [dictionary.allKeys sortedArrayUsingDescriptors:@[ sortDescriptor ]]) 
        id nestedValue = [dictionary objectForKey:nestedKey];
        if (nestedValue) 
            [mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue((key ? [NSString stringWithFormat:@"%@[%@]", key, nestedKey] : nestedKey), nestedValue)];
        
    
   else if ([value isKindOfClass:[NSArray class]]) 

   // This is modified by me
    NSArray *array = value;
    int i = 0;
    for (id nestedValue in array) 
    // A check has been added for NSDictionary
        if ([nestedValue isKindOfClass:[NSDictionary class]]) 
           //Here i used @gilad's answer 
            [mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue([NSString stringWithFormat:@"%@[%d]", key,i], nestedValue)];

        else

        [mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue([NSString stringWithFormat:@"%@[]", key], nestedValue)];
        
        i++;
    
    else if ([value isKindOfClass:[NSSet class]]) 
       NSSet *set = value;
       for (id obj in [set sortedArrayUsingDescriptors:@[ sortDescriptor ]]) 
            [mutableQueryStringComponents addObjectsFromArray:AFQueryStringPairsFromKeyAndValue(key, obj)];
       
    else 
       [mutableQueryStringComponents addObject:[[AFQueryStringPair alloc] initWithField:key value:value]];
   

    return mutableQueryStringComponents;

如上所述，我刚刚在 AFURLRequestSerialization.m 类中编辑了 AFQueryStringPairsFromKeyAndValue，然后它开始按我们想要的方式工作。

【讨论】：

这个怎么用？我需要使用以下格式请求， [ "path": "/", "value": "state": "ACTIVE" , "op": "replace" ] 你能解释一下吗？告诉我你的使用代码..

@karthikeyan 我的请求类似于 [, ,] 格式。正如我在回答中提到的那样，我已经用地雷替换了 NSArray * AFQueryStringPairsFromKeyAndValue(NSString *key, id value) 这个方法

@karthikeyan 如果您仍在寻找解决方案，那么您可以告诉我。我可以尝试给你编辑过的 AFNetworking 框架

感谢重播，我已经做到了，通过使用 NSMutableString，我只是像这样制作了格式，并转换为数据，然后将其发送到服务器，这对我有用，
