Question

我正在做一个非常基本的POST请求。将我的requestSerializationMIMEType设置为我的服务器所期望的RKMIMETypeFormURLEncoded（尽管它是默认设置）。

现在在日志中request.body看起来像这样：

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

服务器中产生的未知表单值。

这里的问题是参数名称，它们在方括号之间，我没有解释为什么他们会像这样序列化！

我的代码与github上提供的示例完全相同。

注意：我已经手动完成了POST请求而没有方括号，并且它工作正常。

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，传递rootKeyPath为空字符串会导致此问题。通过nil可以解决问题。

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

方括号之间的Restkit request.body值
