Question

我试图将JSON字符串发布到php。我创建了JSON为

NSMutableArray *arr = [[NSMutableArray alloc] init];
    [arr addObject:@{@"step1":[[NSArray alloc] initWithObjects:@{@"key1":@"value1"}, @{@"key2":@"value2"}, @{@"key3":@"value3"}, nil]}];
     [arr addObject:@{@"step2":[[NSArray alloc] initWithObjects:@{@"key1":@"value1"}, @{@"key2":@"value2"}, @{@"key3":@"value3"}, nil]}];
    jsonString = [NSJSONSerialization JSONObjectWithData: [NSJSONSerialization dataWithJSONObject:arr options:NSJSONWritingPrettyPrinted error:nil] options:NSJSONReadingMutableContainers error:nil];
NSLog(@"JSON %@",jsonString);

将json打印为

JSON (
        {
        step1 =         (
                        {
                key1 = value1;
            },
                        {
                key2 = value2;
            },
                        {
                key3 = value3;
            }
        );
    },
        {
        step2 =         (
                        {
                key1 = value1;
            },
                        {
                key2 = value2;
            },
                        {
                key3 = value3;
            }
        );
    }
)

我发出请求发送json字符串如下

 NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"2", @"userid",jsonString , @"totaldata", nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:url]];
[client registerHTTPOperationClass:[AFJSONRequestOperation class]];
    NSLog(@"Requesting..");
    [client postPath:@"" parameters:params success:^(AFHTTPRequestOperation *operation, id response){
        NSLog(@"AFN response %@", operation.responseString);
        NSError *error;
        NSDictionary *responseData = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingAllowFragments error:&error];
        complete(responseData);
    }
    failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         NSDictionary *nsDError = [NSDictionary dictionaryWithObjectsAndKeys:error.description, @"error", nil];
         failure(nsDError);
     }];
}

当我从php打印时，我得到了回应

{"json":[{"step1":[{"key1":"value1"}]},{"step1":[{"key2":"value2"}]},{"step1":[{"key3":"value3"}]},{"step2":[{"key1":"value1"}]},{"step2":[{"key2":"value2"}]},{"step2":[{"key3":"value3"}]}]}

我的PHP脚本，

$totaldata = $_POST["totaldata"];
$response = array("json"=>$totaldata);        
 $this->response($response,200);

在php中，我只是打印json字符串以响应json请求。我期望json在请求和响应中是相等的，但作为响应，json随请求的json字符串而变化。在这方面有谁可以帮助我？
