ios - 方括号之间的 Restkit request.body 值

Question

我正在执行一个非常基本的 POST 请求。将我的 requestSerializationMIMEType 设置为 RKMIMETypeFormURLEncoded 作为我的服务器所期望的(尽管这是默认设置)。

现在在日志中，request.body 看起来像这样:

request.body=[param1]=test&[param2]=2724

在服务器中产生未知的表单值。

这里的问题是参数名称，它们在方括号之间，我没有解释为什么它们被这样序列化!

我的代码在某种程度上与 github 上提供的示例完全相同.

注意:我在没有方括号的情况下手动完成了 POST 请求，并且工作正常。

代码

RKObjectMapping *responseMapping = [RKObjectMapping mappingForClass:[GenericResponse class]];
[responseMapping addAttributeMappingsFromDictionary:@{@"error":@"error", @"status":@"status"}];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful); 
RKResponseDescriptor *genericDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:responseMapping method:RKRequestMethodAny pathPattern:@"" keyPath:@"" statusCodes:statusCodes];

RKObjectMapping *requestMapping = [RKObjectMapping requestMapping]; 
[requestMapping addAttributeMappingsFromDictionary:[User generateJSONMapping]];//dictionary mapping
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[User class] rootKeyPath:@"" method:RKRequestMethodPOST];

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"https://foo.com/rest/createUser/"]];
[manager addRequestDescriptor:requestDescriptor];
[manager addResponseDescriptor:genericDescriptor];
manager.requestSerializationMIMEType=RKMIMETypeFormURLEncoded;

// POST to create
[manager postObject:user path:@"" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
    NSLog(@"success");// the request is success but the params are not delivered to the server 
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"fail");
}];

我猜 User 非常简单

@interface User : NSObject
   @property NSNumber *idShort;
   @property NSNumber *idLong;
   @property NSNumber *idCom;
   @property NSString *comment;
   @property NSString *token;

   + (NSDictionary *) generateJSONMapping;
@end


@implementation User
   + (NSDictionary *) generateJSONMapping
   {
      return @{
         @"idShort": @"idShort",
         @"idLong": @"idLong",
         @"idCom":@"idCom",
         @"comment":@"comment",
         @"token":@"token",
         };
   }
@end

问题出在 RKRequestDescriptor 中，将 rootKeyPath 作为空字符串传递会导致此问题。传递 nil 将解决问题。

RKRequestDescriptor *requestDescriptor = [
RKRequestDescriptor requestDescriptorWithMapping:requestMapping
objectClass:[User class]
rootKeyPath:nil
method:RKRequestMethodPOST];
